[219] The crash was attributed to a bleed air system malfunction after an engine overheat condition was detected, shutting down the Environmental Control System (ECS) and OBOGS. 4005 completes successful first flight. The result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. Certification of the improved AN/APG-77(V)1 radar was completed in March 2007, and airframes from production Lot 5 onward were fitted with this radar, which incorporates air-to-ground modes.
