ESCAPE HATCH DEPARTED AIRCRAFT AT 2,200 FEET, SIX MILES WEST OF LANCASTER AIRPORT. NO DAMAGE WAS FOUND ON THE AIRCRAFT. INSPECTION OF THE FRAME, OF THE ESCAPE HATCH OPENING, FOUND NOTHING BROKEN IN THE RETAINING SYSTEM. IT APPEARED THE RETAINING PINS VIBRATED OUT ENOUGH TO ALLOW THE HATCH TO BE PULLED OUT BY THE WIND.
