Narrative:
On short final approach captain requested the customary 30 degree flap selection for landing after which all indications were normal except for a large amount of left aileron required to maintain wings level. After landing, a 'deadheading' flight crew member (riding in passenger compartment) paged the cockpit to report that a piece of flap had separated from the aircraft on short final. We subsequently decided not to raise the flaps during taxi-in. Postflt examination revealed large portion of right outboard trailing edge foreflap had failed and separated. Callback conversation with reporter revealed the following information: this reporter was a B727-200 so and he did attempt to find out about what happened to the aircraft, but other than confirming that the right outboard foreflap had broken from its mounts and departed he was unable. He estimated that about 15 degrees of left wing down aileron was required until the nose was on the runway to control the aircraft with more than that initially.
Original NASA ASRS Text
Title: AN ACR FLC OF A B727-200 HAS THE R OUTBOARD TRAILING EDGE FOREFLAP SEPARATE FROM THE ACFT ON SHORT FINAL APCH.
Narrative: ON SHORT FINAL APCH CAPT REQUESTED THE CUSTOMARY 30 DEG FLAP SELECTION FOR LNDG AFTER WHICH ALL INDICATIONS WERE NORMAL EXCEPT FOR A LARGE AMOUNT OF L AILERON REQUIRED TO MAINTAIN WINGS LEVEL. AFTER LNDG, A 'DEADHEADING' FLC MEMBER (RIDING IN PAX COMPARTMENT) PAGED THE COCKPIT TO RPT THAT A PIECE OF FLAP HAD SEPARATED FROM THE ACFT ON SHORT FINAL. WE SUBSEQUENTLY DECIDED NOT TO RAISE THE FLAPS DURING TAXI-IN. POSTFLT EXAMINATION REVEALED LARGE PORTION OF R OUTBOARD TRAILING EDGE FOREFLAP HAD FAILED AND SEPARATED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THIS RPTR WAS A B727-200 SO AND HE DID ATTEMPT TO FIND OUT ABOUT WHAT HAPPENED TO THE ACFT, BUT OTHER THAN CONFIRMING THAT THE R OUTBOARD FOREFLAP HAD BROKEN FROM ITS MOUNTS AND DEPARTED HE WAS UNABLE. HE ESTIMATED THAT ABOUT 15 DEGS OF L WING DOWN AILERON WAS REQUIRED UNTIL THE NOSE WAS ON THE RWY TO CTL THE ACFT WITH MORE THAN THAT INITIALLY.
