B-24 Liberator Willow Run Assembly Plant
The manufacturing and construction production video for the Consolidated B-24 Liberator heavy bomber. This video is about the Ford Motor Company production plant at Willow Run for B-24's before and during World War II. Ford Motor Company manufactured and built B-24 Liberators under license from Consolidated Aircraft Company. Production rates were so great at the Ford Willow Run plant, which a new B-24 rolled off the production line every 55 minutes.
 
This video shows and example of the periodic ordnance tests and test fight requirements for every Lib coming off the Ford assembly line. The dummy bomb ordnance drop test appears to be performed perhaps over Lake Erie or possibly Lake St. Clair?
 
This video answers many of my earlier aircraft production acceptance protocol questions, I would assume that these aircraft test practices were performed at all aircraft assembly and/or Mod Center locations.

Re:Tribute to Ford Willow Run Liberator Production
The B-24 bomber (serial number 44-48800) shown in the opening of the video crashed before it was accepted by the Air Corps.
 
At 12:27 on the afternoon of 19 August, 1944, B-24J serial # 44-8800 took off from Willow Run Airport on a certification flight. The plane was the 300th plane in the lot and as such was given extra testing to determine the acceptance of the next 300 plane lot. It was the 5,549th Ford built B-24 to come off the assembly line. The plane had not been turned over to the Army Air Forces and was thus the property of Ford Motor Co. It was on its sixth test flight, a high altitude bomb drop, when it crashed in clear weather at approximately 3:40 pm on the farm of Jerry King, about 2 miles ESE of Imlay City, MI. All aboard the plane perished in the accident.
The cause of the crash was later determined to be structural failure of the elevator control surfaces which were found miles away from the crash site in a farm field. This problem was just beginning to become apparent in this model plane and not uncommon during WWII when design changes had to be made on the fly. Indeed, a year earlier on 3 August, 1943, a B-24E crashed near Pueblo, CO under extremely similar circumstances. Recommendations were made to alter the construction to allow for easy visual inspection of these components during pre-flight. It was further determined not exceed 260 mph dive speeds during test dives, the previous allowable speed was 300 mph.

 
According to the official accident Report:
 
            1.  In accordance with the requirements of existing contracts and Materiel Command, Wright Field, letter prh:60-14, dated 6 June 1944, by Major R. M. Sinnen, this airplane, 44-8800, was selected as representative of a production lot of airplanes manufactured by the Ford Motor Company, Willow Run, Ypsilanti, Michigan, and was on its 6th Flight for bomb dropping tests at altitude in operational check of bomb bay doors at all allowable speeds. The airplane left Willow Run at 12:27 and no further radio contact was made. Weather was reported as C.A.V.U. throughout this area. The flight schedule provided for dropping of  bombs at altitude over the assigned area along the shore of Lake Huron. Upon completion of this part of the flight, the airplane descends to about 12,000 feet, at which time the airplane is put into a power dive testing the bomb bay door operation at all allowable speeds. It is believed this procedure was followed, although no information was obtained to ascertain this. It is believed that bomb bay door operation was tried and a "squawk" was found, necessitating regaining altitude for a repetition of the test.
 
2.  The first actual witness to the flight of the plane immediately prior to the crash, located the ship in an area south of the scene of the accident, climbing from a low altitude and proceeding in a northeasterly direction. The ship was then observed by other witnesses to proceed in a northerly direction then turning to the west followed by a turn to a southeasterly course. At this time the ship was reported to be several miles north of the location of the crash at an estimated altitude of 7,000 to 10,000 feet. It was then observed to proceed in a southeasterly direction in a power dive. Shortly after the power dive was started, witnesses observed pieces of what appeared to be paper fall from the airplane. The airplane continued in this power dive at a high rate of speed with all four engines running. Then it was observed to go into a steeper dive and then suddenly into a vertical dive at an altitude of approximately 300 or 400 feet.
 
3.  Judging from the impact, the airplane struck at a terrific speed. The airplane exploded on impact, scattering fragments over a wide area. Evidence indicated that at the time of the crash one Flight Engineer was in the Bombardier's compartment where he could operate the bomb bay doors. Apparently, the other Flight Engineer was in the or near the Radio compartment where he could inspect the operation of the doors. The Pilot and Co-pilot in their respective places.
 
4.  The pieces which appeared to be paper that fell from the airplane in flight were found to be elevator trim tabs, part of the elevator, bomb bay doors and parts of the nose turret. These pieces were found in the adjacent farms on the course of the airplane, about a mile to a mile and half from the scene of the accident.
 
5.  It is the opinion of the Board that the Pilot attempted to use the elevator trim tabs to recover from the test dive for bomb bay door operation, at which time the elevator tabs failed, causing the structural failure of the elevator which made it impossible for the Pilot to recover from the dive. As the dive continued, speed of the airplane increased, causing the failure of the bomb bay doors and nose turret.
 
6.  There is a remote possibility that bomb bay doors were torn off in the test operation which struck the elevator, causing further structural damage. The failure of the elevators resulted in the Pilot losing complete control of the airplane, with the result that the airplane assumed an ever increasing diving angle
            On 19 August 1944 approximately 1540, Airplane B-24J #44-8800 crashed two miles north and one and one-half miles east of Almont, Michigan. The ship was piloted by Lt. John K. Howmiller, AC, Assistant AAF Resident Representative and FLight Engineering Officer, stationed at the Ford Motor Company Willow Run Bomber Plant, and co-piloted by Capt. Thomas W. Vaughn, AC, Assistant AAF Resident Representative and Assistant Operations Officer, stationed at Ford Motor Company Willow Run Bomber Plant. Two Ford Motor Company employees, Flight Engineers C.R. Wonack and Harvey D. Jenkins, completed the crew of the ship. All members of the crew were instantly killed. The Subject airplane was on a routine Bomb Dropping Test prior to Army Air Forces acceptance and was still the property of the Ford Motor Company. Preliminary investigation was requested by the District Intelligence Officer, Central Procurement District. The Detroit office of the Federal Bureau of Investigation was notified upon receipt of the crash by the District Intelligence Officer.
 
            1.  On 19 August 1944 this Agent surveyed the scene of the accident which was located on Section 11 of the Almont Township, known as the Jerry King Farm. The property on which the plane crashed is owned by Harry L. Armstrong, 201 Lapeer Street, Lake Orion, Michigan. It appeared from the scene of the accident that the airplane approached from the northwest, traveling in a southeasterly direction. (Exhibit A) As it was over the above-mentioned land it made an almost vertical dive, striking the ground head-on. The land is partially wooded pasture land and the position of branches broken from the trees indicate that the final dive was almost straight down. The plane apparently exploded upon contact with the ground and the force of the impact and the explosion scattered parts of it over a 300 yard square area. All four engines of the ship were buried several feet in the ground. The ship was completely demolished (Exhibit B). Parts if the fuel tanks, engine cowlings, selector valves, and other parts were found from 200 to 300 yards from the actual crash, apparently having been blown there the explosion.
 
            2.  The destruction of the plane was such that very little could be ascertained from an examination of the scattered wreckage. Imprints on the ground made it appear that the leading edge of the left wing probably struck the ground first with the nose section, all four engines and the right wing striking immediately thereafter.
  
The plane crashed at the height of production, the most produced aircraft of WWII, hunderds of changes were made during the production of the aircraft, changes were made as a result of the accident up through the end of its production.  In the first year alone, 1941,  there were 575 changes required. The total number of B-24s built at Willow Run was 8,685. At its peak, August 1944, Willow Run produced 428 B-24s per month. In the beginning in December 1941, a total of 107 bombers had been offered to the Army Air Corps, but only 56 were acceptable. Part of the problem was that, as in the auto industry, the plant was using hard steel dies instead of the softer dies more conducive to the multiple changes demanded by the aircraft industry.  The B-24 contained 100,000 parts, as opposed to the 15,000 needed in a 1940 automobile. Test flying the newly built planes and putting them through their paces required alot of skill, unfortunetly this one plane did not pass the test.  I've read the when many of the Ford built planes arrived at other bases they were grounded due to defects and poor quality parts. Rework depots were set up and the planes were majorly modified before heading into combat areas.  It was a great plane, but it did have its problems.
 
I located the crash site back in 2009. It is located on a farm in Almont Michigan. Very little remains of the plane, but I still found some parts!

Re:Tribute to Ford Willow Run Liberator Production
Dave,
Jeff has a great website and quite thorough follow-up crash investigation, quite remarkable. Other than the one crash at Pueblo; are you aware of similar fatigue related failures during test flights at any of the other four assembly plants resulting in crashes?

Re:Tribute to Ford Willow Run Liberator Production
Scott, thanks for posting this!  However, for some reason, I have not yet been able to open the clip.  What is the link?  I'm not sure if the difficulty is with my laptop or the clip itself at this point...  That being said, the background info was interesting.  Sometimes I think I've "forgotten" more facts and trivia about Ford Willow Run than most will learn, BUT I ALWAYS find and welcome something new.  Most of the dummy ordnance was dropped over Lake Erie and, on occasion, over Lake St. Clair.  I can just imagine what it must have been like thru April and May 1944 when FO was at its peak production in April hitting 455 planes in 450 every 59.34 minutes across 25 working days using two nine-hour shifts!  As I've mentioned in other places, it seems incredible to have reached this point especially after the early setbacks when the media had dubbed Willow Run as "Willit Run!"

Re:Tribute to Ford Willow Run Liberator Production
Dave T. and Scott, There were other incidencies which are referenced and scattered about here on this Website.  Back in 2009 on my Thread about Willow Run, we had a lot of chatter going on a particular incident (intermittently on posts # 129-144 - more or less - especially #144) involving even possible sabotage: http://forum.armyairforces.com/History-Willow-Run-Liberators-m121256-p8.aspx.  Strange, but August eeriely seemed to be when these incidences occurred here in MI. Somehow or other it seemed to be during foul weather also.  I have this grainy old pic of a mid-August, night-time thunder storm over the new FO WR plant which always conjures up images of these incidences for me....  BTW, an EXCELLENT "resource person" on this Site for concerns about "fatal accidents" would be Tony J. Mireles.

Re:Tribute to Ford Willow Run Liberator Production
Steven,
I don’t believe weather played a part in this 19 August, 1944 incident as the investigation report states conditions to be CAVU “Ceiling And Visibility Unrestricted”. The alleged sabotage at the San Diego facility is an interesting twist. As it appears the perpetrator was arrested was it determined to enemy activity or a Labor/Union/Personnel issue at the factory?

Re:Tribute to Ford Willow Run Liberator Production
Scott,
I know Tony J. Mireles. I have investigated dozens of B-24 accidents all across the USA. Reguarding this B-24, 44-48800 accident, I found that one of the main causes was the fact that the plane was much heavier than originally designed. The extra weight caused the failure of the  Aileron. This may be a factor in other accidents, but was not discovered until this one. I have the copy of the change that was made as a direct result of this accident. They made the ailerons much more stronger. See attached documents. I'm currently researching other B-24 accidents and crash sites to determine if these design problems were also a factor. I'm also looking for more FORD built B-24 crash sites.
The other known problem with  the B-24 was the tail falling off. This was later found to be a result of vibration. I believe there is a thread on that problem somewhere.
The engineers at Ford made changes as they went along after they learned of problems and solutions, unfortunately sometimes they learned too late and design flaws resulted in accidents and deaths. The accident of B-24 44-48800 was tragic but something was learned from it and changes were made as a result. The B-24 is still my favorite plane, but it did have problems.

Re:Tribute to Ford Willow Run Liberator Production
More from the Official accident report reguarding B-24 44-48800. During a bomb bay door operation test conducted 19 Aug 1944 while diving the elevator tabs failed causing the structural failure of the elevator which made it impossible for the pilot to recover from the dive.  The B-24J crashed due to loss of elevator control surfaces which broke off during the dive.
Recommendations from the accident investigation board.
1. Radio contact should be maintained on bombing tests at frequent intervals.
2. Universal Joint assembly with the elevator should be of such design so that visual inspection could be made of the detailed parts as an assembled unit.
3. Further investigation and study should be made of the strength of the elevator around the tab area for all allowable flight conditions
4. Dive speed should be restricted to 260 miles per hour for bomb bay door operation.
Research: According to the pilot manual that I have for the B-24D, the diving speed limits are 56,000 lbs are 275 MPH The dive speed remained the same in the B-24J as the B-24D and was unchanged in a B-24J manual dated in 1945.  The pilots were briefed to “Air loads build up rapidly on any large airplane in a dive; therefore avoid abrupt movements of the controls. Control trim should be maintained with the idea of keeping tail surface forces at a minimum. It is better to trim the airplane to slightly nose heavy rather than tail heavy.” Most likely the test pilots were using abrupt movements during the test flight.  So, the change was mainly on how to fly the bomber and not the max speed limit.  2. The area around the tab area in the elevator was modified after the accident and strengthened in latter model B-24s. This was confirmed by the attached service bulletins. So,  this means that the engineers did make changes to fix the tab problem and last but not least, the 4 crew members did not die in vein, something was learned from the tragic accident.

Re:Tribute to Ford Willow Run Liberator Production
More research: By December 1942 a total of 107 bombers had been offered to the Army Air Corps, but only 56 were acceptable. Part of the problem was that, as in the auto industry, the plant was using hard steel dies instead of the softer dies more conducive to the multiple changes demanded by the aircraft industry. In the first year alone there were 575 changes required.
I would like to know how many official changes were made to the B-24 during WWII.

Re:Tribute to Ford Willow Run Liberator Production
The first completed B-24 came off the assembly line at Willow Run on May 15, 1942, I’m sure WR was having production start up problems as all new manufacturing facilities will regardless of the product they are producing. To compound these difficulties it appears they were getting little support form Consolidated in San Diego. This was the beginning of the ramp up mobilization with other companies producing their product under contract. I would think this to be a hard pill to swallow by the aircraft Original Equipment Manufacturers as proprietary designs and manufacturing procedures that once might be considered company secretes were now being given away wholesale. To further compound these difficulties Consolidated as of November 1941 was under new management as Reuben Fleet had sold out to AVCO with operations falling under their subsidiary Vultee.
 
Here is an interesting link: http://www.liberatorcrew.com/06_B-24_Prod.htm there is a reference here about Libs training at Pueblo coming from WR, but it’s not clear if this is referring to all Libs at Pueblo or just one crew that went on to combat in Italy, presumably with the 15th Air Force. It is also unclear if one thing leads to the other regarding the previously noted similar crash incident at Pueblo.

Re:Tribute to Ford Willow Run Liberator Production
Scott,  A couple of things here...  The first true Lib off the Assembly Line thru the entire "assembly process" with FO parts was on 9.1.42 while the one from 5.15.42 was a "training ship" assembled with parts from Consolidated at CO by Ford's educational unit.  A great read is:  The Wartime Journals of Charles A Lindberg   (http://forum.armyairforces.com/tm.aspx?m=147658&high=Wartime+Journals+of+Charles+A There is about a 200 page section dedicated exclusively to his work at Willow Run as a "Consultant" in which he goes thru all the processes that needed to be "corrected" in adapting the Ford automotive "mechanized assembly process and interchangeable parts" to the production of airplanes.  This included massive engineering changes, massive hiring and  training, the use of soft steel dies (as DaveT has mentioned) in lieu of hard, incomplete and often non-existent prints from CO, and the list goes on and on!  Also, thanks for the note in post #7.... I missed that ealier in DaveT's info about the CAVU.

Thanks, Scott!  I think that just about everyone flags me on this 13 min clip.  I have both the VHS  and a re-mastered DVD of the full 43 min USAAF / Ford  version.  It's good "promo," but really doesn't do justice to the people who built the Libs at FO.  On pages 15, 16 and 17 of the attached link is a "brief" article I wrote for the Heritage Herald Review giving a glimpse of some of the people who worked at Willow Run:  Rosies, the little people, Charles Lindbergh and the father of one my engineers who was, back in the day, an engineer for Ford.

B-24 Sabotage in San Diego

 The alleged sabotage at the San Diego facility is an interesting twist. As it appears the perpetrator was arrested was it determined to enemy activity or a Labor/Union/Personnel issue at the factory? 
Scott

Scott, do you have more details of this incident? Is it discussed in this forum?
 
Dad ferried new B-24s from Wayne-Romulus in late '43 and often commented about the glitches they encountered in those first long-distance flights. He also picked up P-39s in Buffalo and those all had problems as well. These appear all to be related to quality control and the poor-quality of the work force.

Re:B-24 Sabotage in San Diego
David,
 
I’m at a loss here as I cannot find the related link to a sabotage incident in San Diego. I’ve read and re-read all of the information in this thread previous to my post regarding the alleged San Diego incident and can find no reference. This is quite disturbing as there are no edits of any kind in this thread so at this point I must assume I misread Steven’s referenced post from 2009  http://forum.armyairforces.com/History-Willow-Run-Liberators-m121256-p8.aspx but this is all related to WR not  San Diego. If I was using an outside source, I did not book make it and in an independent web search today on the related topic I’m getting a negative response with no results. I’ll keep looking, but at this point I’m beginning to think this was an error on my part.

The B-24 bomber (serial number 44-48800) shown in the opening of the video crashed before it was accepted by the Air Corps.

At 12:27 on the afternoon of 19 August, 1944, B-24J serial # 44-8800 took off from Willow Run Airport on a certification flight. The plane was the 300th plane in the lot and as such was given extra testing to determine the acceptance of the next 300 plane lot. It was the 5,549th Ford built B-24 to come off the assembly line. The plane had not been turned over to the Army Air Forces and was thus the property of Ford Motor Co. It was on its sixth test flight, a high altitude bomb drop, when it crashed in clear weather at approximately 3:40 pm on the farm of Jerry King, about 2 miles ESE of Imlay City, MI. All aboard the plane perished in the accident.
The cause of the crash was later determined to be structural failure of the elevator control surfaces which were found miles away from the crash site in a farm field. This problem was just beginning to become apparent in this model plane and not uncommon during WWII when design changes had to be made on the fly. Indeed, a year earlier on 3 August, 1943, a B-24E crashed near Pueblo, CO under extremely similar circumstances. Recommendations were made to alter the construction to allow for easy visual inspection of these components during pre-flight. It was further determined not exceed 260 mph dive speeds during test dives, the previous allowable speed was 300 mph.

It is believed that bomb bay door operation was tried and a "squawk" was found, necessitating regaining altitude for a repetition of the test.

2.  The first actual witness to the flight of the plane immediately prior to the crash, located the ship in an area south of the scene of the accident, climbing from a low altitude and proceeding in a northeasterly direction. The ship was then observed by other witnesses to proceed in a northerly direction then turning to the west followed by a turn to a southeasterly course. At this time the ship was reported to be several miles north of the location of the crash at an estimated altitude of 7,000 to 10,000 feet.

The airplane continued in this power dive at a high rate of speed with all four engines running.

3.  Judging from the impact, the airplane struck at a terrific speed. The airplane exploded on impact, scattering fragments over a wide area. Evidence indicated that at the time of the crash one Flight Engineer was in the Bombardier's compartment where he could operate the bomb bay doors. Apparently, the other Flight Engineer was in the or near the Radio compartment where he could inspect the operation of the doors. The Pilot and Co-pilot in their respective places.

4.  The pieces which appeared to be paper that fell from the airplane in flight were found to be elevator trim tabs, part of the elevator, bomb bay doors and parts of the nose turret. These pieces were found in the adjacent farms on the course of the airplane, about a mile to a mile and half from the scene of the accident.

Re:B-24 Sabotage in San Diego
Scott,
I'm more interested about the tails falling off B-24s or the thousands of changes made to the B-24 during production.

Tribute to Ford Willow Run Liberator Production
DaveT,
I would think that these are the more important questions as well but online sources are sorely lacking in both categories. Perhaps the twin vertical stabilizer issue is cover in Tony Mireles’s book series but I’ve not seen these publications. The massive number of modification is reportedly cover in CONSOLIDATED MESS by Alan Griffith: http://forum.armyairforces.com/CONSOLIDATED-MESS-by-Alan-Griffith-m218068.aspx
 
The other question I have is why the name of this thread changed from “Tribute to Ford Willow Run Liberator Production” to “B-24 Sabotage in San Diego” Who thought that was a good idea?
