Analysis

While taxiing to takeoff & on the takeoff roll, the left brake overheated. Ten to fifteen mins after departure both tires on the left main landing gear exploded. The bearings and brakes also seized due to the high temperatures. Upon arrival at the dest, the normal gear extension system was inoperative and the emergency extension system was utilized. No further damage was incurred during the landing. Investigators discovered a sticking valve in the left parking brake. Maintenance records revealed that on June 19 and 22, difficulty was reported in releasing the parking brakes; maintenance personnel could not duplicate the discrepancy and returned the acft to service.
