GRUMMAN FLXIBLE CORP.
The problem
CRACKS MAY DEVELOP IN THE TRUNNION TO WHICH THE APEX OF THE "A-FRAME" IS ATTACHED. THESE CRACKS MAY PROGRESS TO THE POINT THAT THE TRUNNION COULD FAIL AND THE A-FRAME COULD SEPARATE FROM IT. IF THIS OCCURS, THE A-FRAME COULD COME INTO CONTACT WITH THE CONDUIT CARRYING AIR, AS WELL AS THE ELECTRICAL AND FUEL LINES.
What owners should do
TRUNNION WILL BE INSPECTED FOR CRACKS AND, IF POSSIBLE, CRACKS WILL BE REPAIRED AS AN INTERIM MEASURE. ALL TRUNNIONS WILL BE REINFORCED BY GRUMMAN; ANY DEFORMED TRUNNIONS WILL BE REPLACED WITH A REINFORCED PART. REPAIRS WILL BE PERFORMED AT NO CHARGE.
