What was found
THE PILOT DISCOVERED THAT THE GIRT BAR FOR THE EMERGENCY ESCAPE SLIDE AT R1 DOOR WOULD NOT REMAIN IN THE ARMED POSITION. RECEPTACLES WERE OBSTRUCTED ENOUGH THAT THE GIRT BAR WOULD KICK OUT OF LATCH. THE DOOR SLIDE GIRT BAR LATCHING RETAINER WAS CLEANED AND THE FOLLOW-UP FUNCTIONAL CHECK WAS GOOD.
