What was found
DURING REGULAR MAINTENANCE AND LUBRICATION OF THE FLAP CONTROL ROD ENDS, A CRACK WAS NOTICED IN THE FLAP ITSELF. THE CRACK IS AROUND THE BASE OF THE BRACKET FOR THE ROD END ATTACHMENT, THROUGH THE FLAPS SPAR. THERE IS NO SUPPORT ON THE BACK SIDE OF THE SPAR FOR THE 4 BOLTS THAT HOLD THE BRACKET IN PLACE. A BEEF-UP OF THIS AREA WILL BE NEEDED TO PRECLUDE THIS HAPPENING. SUSPECT CAUSE DUE TO EXTENSION OF FLAPS AT A HIGHER THAN NORMAL SPEED.
