IN THE "FALSE LATCH" CONDITION, THE REAR DOORS MAY GIVETHE IMPRESSION THAT THE DOOR IS PROPERLY LATCHED WHEN IT IS NOT. THIS COULD LEADTO PASSENGERS AND/OR CARGO FALLING FROM REAR DOORS WHICH CAN OPEN WITHOUT PRIORWARNING.
Remedy
CHECK THE DOOR LATCHES AND STRIKERS FOR CORRECT ALIGNMENT AND REPAIR IF NECESSARY; ALSO INSPECT REAR DOOR HINGES FOR CORROSION AND REPLACE IF NECESSARY.
