WASHINGTON The Department of Defense Inspector General on Monday disputed an Air Force investigation that blamed pilot error rather than oxygen supply problems for the crash of an F-22 Raptor in November 2010.
The Air Force grounded the jets considered the worlds most advanced for several months in 2011 after reports by pilots that oxygen-supply system failures lead to symptoms including headache, fatigue and nausea.
The Air Force report, completed in late 2011, concluded that it was not an oxygen supply problem, but several errors by Capt. Jeffrey Haney, who was killed, that led to the crash north of Anchorage, Alaska.
I find the cause of the mishap was [Haneys] failure to recognize and initiate a timely dive recovery due to channelized attention, breakdown of visual scan and unrecognized spatial disorientation, wrote the officer who headed the Air Force accident investigation.
But a report by the DOD IG said the Air Force conclusion was not supported by the facts within the crash report.
The Air Force investigation concluded that while the planes oxygen supply had stopped, Haney failed to activate a backup system or react quickly enough to recover control of the aircraft, which was diving, while trying to restore airflow to his mask.
But the facts in the Air Force report dont prove that Haney kept his mask in place in the full up position during the incident, the IG report said.
The report also failed to properly document how the Air Force concluded that lack of oxygen, gravity-induced unconsciousness and other physiological factors did not cause the crash, the IG report said.
Additionally, the report doesnt explain how what investigators concluded were the main contributors to the crash actually worked together to cause it.
Failure to adequately explain this interrelationship calls into question the AIB Statement of Opinion regarding the cause of the mishap, the IG report said.
The Air Force should take another run at making sense of the November 2010 crash, the IG report said.
We recommend that the Judge Advocate General of the Air Force reevaluate the AIB report and take appropriate action in light of the findings ...," the report said.
In response, the Air Force said it had reviewed the IGs findings but upheld the crash reports conclusions.

Here's the IG report: http://www.airforce-magazine.com/SiteCollectionDocuments/Reports/2013/February%202013/Day13/DODIG_F-22_020613.pdf
All on the AIB should be hammered, it was totally unsat.
USAF isn’t going to stand for any criticism of the F-22 or F-35.
The former OT&E guy in me suspects there was so much pressure to get the plane approved, and Lockheed was making so much off of making everything new, needed or not, that this design was allowed to pass.
We would have been vastly better off if we had decided to build BOTH the F-22 & F-23 on a competitive basis, rather than the F-22 followed by the F-35...

Gotta agree with you. Competition in production aircraft would mean ensuring higher cquality than the other guy and failures would be highly noted.
No F-22 on there yet though :(

They left out "because of hypoxia." in the above.
Yup. They should put the AIB in a pressure chamber, suck out the air until it matches the air pressure at 50,000 feet, and we’ll see how well they do their job. Oh wait, that happened. And the result is the report that you see here.
