## Discrepancy

THE RIGHT ENGINE INBOARD ACCESS COWLING (PN: 212-53105-1) DISENGAGED ALLOWING THE COWLING TO OPEN IN FLIGHT.  THE COWLING DID NOT DEPART THE AIRCRAFT.  THE LATCHES WERE CLOSED AND LOCKED, BUT THE FORWARD LATCH SHOWED SIGNS WEAR TO THE HOOK AND MOST LIKELY DISENGAGED ALLOWING THE AIR-STREAM TO ENTER THE COWLING OVERLOADING THE 2 REMAINING LATCHES.
