Narrative:
THE AIRCRAFT LOST POWER AND CRASHED IN A TRACTOR TRAILER PARKING LOT, DESTROYING THE HELICOPTER AND CAUSING SERIOUS INJURIES TO THE PILOT AND ONE PASSENGER. THE INVESTIGATION REVEALED AN IMPROPER FUEL FLOW SWITCH, WHICH HAD NO CHECK VALVE PROTECTION INSTALLED ON SYSTEM NO 1. THE FAA CERTIFICATION BRANCH (ASW-170) STATED THAT IF THE WRONG FUEL FLOW SWITCH IS USED AND THE BOOST PUMP CIRCUIT BREAKERS ARE PULLED, A FLAME OUT IS LIKELY. THE PILOT SAID HE PULLED THE MASTER CAUTION BREAKER AND MAY HAVE PULLED THE BOOST PUMP BREAKERS 'PREPARING FOR LANDING'. THE FUEL BOOST PUMP CIRCUIT BREAKERS WERE PULLED AND THERE WERE APPROXIMATELY 27 GAL OF FUEL REMAINING, WHEN THE ENGINE QUIT.

Of the five persons on board, two were seriously injured, and three received minor injuries. Registration N555GC cancelled by the FAA on December 12, 1988
