Narrative:
Background: T/M/south sabreliner T39G is a military owned aircraft maintained by contractor. By contract only FAA-pma parts are to be utilized. Incident: prior to takeoff the pilot experienced an uncommanded right engine shutdown; accompanied by a fuel leak (right engine). Maintenance reported the fuel flow transmitter to be the cause of both the fuel leak and uncommanded engine shutdown. Cause: the fuel flow had failed internally due to (6 each) allen head bolts backing out. The F/F transmitter separated into two halves when it was removed from the engine. When all 6 of the internal bolt backed out it broke an internal guide tube. Preventive action: safety wire allen head bolts.
