## Discrepancy

DURING TAKEOFF, PILOT VEERED OFF RUN WAY, STRIKING A RUNWAY LIGHT.  THE PILOT CLAIMED THAT THE LT BRAKE WAS DRAGGING, CONTRIBUTING TO THE INCIDENT.  SUBSEQUENT REPORTS FROM MECHANIC, REVEALED THAT THE PISTON O-RING ON THE LT CALIPER, PN MS 28775-213, WAS FOUND PINCHED DURING DISASSEMBLY. INSP OF THIS AREA SHOULD INVOLVE CLOSE EXAMINATION OF FLUID LEAKAGE AND ABNORMAL PUCK/DISC WEAR.
