The flight crew departed for the destination airport knowing that the anti-skid system was inoperative. While in flight the flight crew briefed the operational procedures for landing with an inpoerative anti-skid system, including manual deployment of the speed brakes and thrust reversers before using minimal braking during the landing to avoid tire blowout. During the landing the flight crew encountered four blown main landing gear tires, resulting in minor damage to the airplane. An examination of the wheels, tires, and brakes revealed no anomalies. Further examination of the airplane and its systems revealed no anomalies aside from the inoperative anti-skid system. The flight data recorder data depicted no deployment of the speed brakes, no use of the thrust reversers, and an increase in brake pressure at the same time weight was transferred to the nose gear, consistent with brake application upon landing.
The flight crew's improper landing technique for an inoperative anti-skid system resulting in locked brakes and four blown main landing gear tires.
