Abstract:

The aircraft demonstrated a 1.6-hour mean time between failures and a 1.5-hour mean time between aircrew writeups. The overall aircraft reliability was significantly degraded by the low reliability of the flight controls and most avionics subsystems. The reliability of most non-avionics subsystems was acceptable. The contractor predicted that 23.8 maintenance manhours per flying hour would be required, and 48.0 manhours were actually measured the difference was attributed to low reliability. Except for excessive removal, bench check, and replacement of good components during troubleshooting, the maintainability of the FB-111A was good.
