Incident at St. Martins, N.B.


1999-02-19: The Flight Instructor was demonstrating a precautionary approach procedure to the student. The aircraft had 40 degrees of flap selected. During the overshoot and climb the Instructor selected flaps up. During the flap retraction, the left flap jammed. The pilot maintained control of the aircraft, declared "PAN" and returned to Saint John for an uneventful landing with ERS on standby. The left flap received minor damage. The operator will submit a complete damage report to the TSB upon aircraft inspection and will submit an SDR to Transport Canada. TSB case closed. Update: Maintenance reported that the left flap track inboard roller assembly needle bearing (PN 0523920) had seized and that continued operation of the flap in this condition had caused the roller to wear a flat and make a burr on the flap track. Maintenance suspects that the left flap had jammed on the burr during retraction. The right flap was inspected and the inboard roller bearing was also seized although the track wear was less evident.
