The September 18 crash of a T-6A Texan II trainer was caused by a contractor’s failure, according to an official Air Force investigation. No one was killed and there was minimal damage to civilian property, but the $5.7 million plane was destroyed. The crash occurred a few miles away from Joint Base San Antonio-Randolph, Texas, while the plane was returning to base following takeoff and landing practice. The Air Force Accident Investigation Board determined that a fuel transfer tube locking plate was improperly installed during a 4,500-hour engine overhaul. The mistake caused engine failure when the plane “was not in a position to land safely,” according to the report.
