After the Air Force was informed of the Inspector General's conclusions, the service said it convened a separate task force to review the AIB report. The task force found that while some portions of the AIB could have been written more clearly, the service stands by its original accounting of the cause of the crash.
"That group of experts validated the AIB's conclusions," an Air Force spokesperson told ABC News.
The spokesperson said the service is currently rewriting its crash report to clarify certain points raised by the Inspector General's report.
Last August the plane's primary manufacturer, Lockheed Martin, along with other defense contractors involved in the plane's production, settled a wrongful death lawsuit with Haney's widow, Anna. The suit had contended that the companies knowingly provided the Air Force with a "defective" aircraft and that Capt. Jeff Haney was a casualty of that decision. The terms of the settlement were not disclosed.
