Fighters' age may play role
By Eric Rosenberg, Hearst Newspapers
WASHINGTON -- The Air Force is still trying to determine whether The Boeing Co. should be held legally liable for defective parts on the service's F-15 Eagle aircraft fleet, a top Air Force acquisition official says.
Air Force Lt. Gen. Donald Hoffman, the service's top uniformed acquisition officer, said in an interview that the investigation is continuing. "At this point, there is no smoking gun that says, 'Aha.' "
The Air Force grounded the entire fleet of 665 jets after a spectacular midflight accident Nov. 2 in which the front section of a Missouri Air National Guard F-15 broke off during a high-stress maneuver. The pilot survived. An accident board determined that it was caused by poorly made "longerons" -- specialized metal beams that help stitch the aircraft together.
McDonnell Douglas Corp. manufactured the F-15 fleet; Boeing later bought the company.
All but 161 F-15s have been cleared to return to operations after they were inspected, said Lt. Col. Jennifer Cassidy, an Air Force spokeswoman at the Pentagon. "Every jet is getting an individual review to determine the severity of the longeron issue," she said.
Hoffman said one mitigating factor in ascribing liability to Boeing is that the aircraft are old -- the average age of the planes is over 25 years -- and the aging process and length of service may be as much a factor as the poorly made longerons. The F-15 that broke apart was 27 years old and had about 5,600 flight hours out of a life expectancy of 8,000 hours.
Hoffman used a car analogy to explain the dilemma. If you take your car back to the dealer "because it is worn out and you say this part wasn't made the way it was supposed to, you'll have a lame argument there," he said.
Air Force officials said last month that determining legal liability will partially hinge on the nitty-gritty of the contractual relationship and obligations between McDonnell Douglas and the Air Force. Specifically, the Air Force is trying to determine whether the service accepted delivery of the jets knowing that some had defective longerons.
However, many contracting records that would show this level of detail have been discarded over the years because the aircraft are so old.
"There isn't a big file cabinet where you can go back and get all this information," Hoffman said. "We are doing due diligence to see whether there is any residual liability from the manufacturing process."
The Air Force has not decided what to do with the 161 jets that have faulty longerons. Officials are considering replacing the longerons; this would be a costly remedy because each longeron costs about $250,000 and each aircraft has several longerons.
The best-case scenario, said Cassidy, is that the planes might be returned to service but with more frequent inspection.
Still another possibility is that the service might decide the jets are too risky to return to service and retire them early.
The plane is also used by the air forces of Israel, Saudi Arabia and Japan.
