Factual narrative
AFTER A REPOSITIONING FLT, THE MAIN GEAR COLLAPSED. AN EXAM OF THE HAND PUMP SELECTOR CONTROL VALVE REVEALED THAT ONE OF THE TWO DUMP PORTS FOR THR FLAP POSITION HAD A HYDRAULIC LEAK. REPORTEDLY, THIS ALLOWED SYSTEM PRESSURE TO RETRACT THE GEAR. THE VALVE, P/N 9055-1, HAD A TOTAL FLT TIME OF 1662.8 HRS SINCE BEING INSTALLED ON 7/21/81.
