Hmm, eerily similar.
F-16D, Shaw Air Force Base, South Carolina, April 18, 2005. Onboard: one pilot, one passenger. No fatalities. Both pilot and passenger ejected safely following engine failure in an F-16D assigned to the 20th Fighter Wing at Shaw AFB. According to the Air Force Accident Investigation Board's report, "There is clear and convincing evidence that the cause of the mishap was the ME's [mishap engine's] catastrophic failure and sudden lack of thrust due to High Pressure Turbine (HPT) blade failure. There is clear and convincing evidence that the HPT blade failure was caused by the required blade seals not being installed in the HPT rotor assembly during scheduled maintenance." During the post-crash examination of the F-16D's General Electric F110-GE-129 engine, investigators found that no blade seals were present in the HPT rotor assembly. "Additionally," the Air Force report noted, "the HPT blades lacked witness marks, which are routinely made by the blade seals--further indicating no seals were ever present. The specific maintenance actions that led to the failure to install the required blade seals included not heeding a caution in a technical order, which warned that "missing HPT rotor blades seals will cause HPT rotor blade failure." The maintenance crew also did not accomplish steps in the technical order that included not only installing the seals but also inspecting the seals to make sure they are installed properly and testing their fit with a piece of shim stock. "Therefore, two additional opportunities to avoid the mishap were missed," stated the Air Force report.
