## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ONE CFI AND ONE PILOT WERE PRACTICING AIR WORK AND TOUCH AND GOES AT BYRON AIRPORT. WHILE PERFORMING A POWER OFF LANDING WITH FLAPS AT 40% THE APPROACH WAS SHORT. POWER WAS APPLIED, FLAPS SELECTED TO 20 THEN 10 THEN 0. AT APPROX. 100-300 FT AGL, THE PIC SITTING IN THE RIGHT SEAT FELT LEFT ROLL. HE HAD TO APPLY YOKE PRESSURE TO COUNTERACT THE ROLL. AT APPROX. 400-600 FT AGL HE TRANSFERRED CONTROL OF AIRCRAFT TO CFI, DUE TO ABNORMAL CONDITION. HE LOOKED OVER HIS RIGHT SHOULDER AND IDENTIFIED A BENT FLAP. NOTIFIED CFI, CFI PERFORMED CONTROLLABILITY CHECK AND LANDED WITH OUT INCIDENT.

THE INBOARD FLAP ROLLER CAUGHT IN THE TRACK DURING TRANSITION. THE FLAP CONTINUED TO BE RETRACTED BY THE ACTUATOR. THIS CAUSED THE FLAP TO DEVELOP A BEND OF APPROX 30 DEGREES. THE APEX OF THE BEND WAS LOCATED AT THE ACTUATOR ATTACH POINT.
