What was found
(CAN) THE AIRCRAFT SAT FOR APPROXIMATELY 7 YEARS. AFTER A POWER LOSS IN FLIGHT, SUBSEQUENT INSPECTION OF THE INJECTOR NOZZLES (TO FIND CONTAMINATION PRESENT) THE FUEL SYSTEM WAS SENT FOR REPAIR. IT WAS GREEN-TAGGED AS REPAIRED. PROBLEM STILL PRESENT, WENT BACK, WAS BENCH-CHECKED AND PASSED. PROBLEM STILL NOT FIXED, SENT BACK, GREEN-TAGGED AGAIN, PROBLEM STILL PRESENT. FINALLY, WE OPENED ONE OF THE UNUSED PORTS AND THE ATTACHED PHOTOS SHOW THE CONTAMINATION THAT WAS FOUND. A NEW (OVERHAULED) FLOW DIVIDER WAS PURCHASED AND INSTALLED. PROBLEM HAS NOT RETURNED.
