TULSA, OK, USA
N6374M
CESSNA 152
THE PILOT RECEIVED A CLEARANCE TO TAXI INTO POSITION AND HOLD ON RUNWAY 19R. SHORTLY AFTER HOLDING THE PILOT HEARD WHAT HE BELIEVED TO BE A CLEARANCE FOR HIM TO TAKEOFF. HE ACKNOWLEDGED THE CLEARANCE AND INITIATED A TAKEOFF ROLL. AFTER THE AIRCRAFT ATTAINED MINIMUM FLYING AIRSPEED, HE WAS INSTRUCTED TO ABORT THE TAKEOFF. HE REDUCED POWER AND BEGAN BRAKING. THE PILOT STATED, 'THE LEFT BRAKE GRABBED MORE THAN THE RIGHT', AND THE AIRCRAFT WAS REPORTED VEERING TO THE LEFT, DEPARTING THE RUNWAY, AND STRIKING A 'PAPI' LIGHT. IN ONE OF THE TWO SUBMITTED STUDENT PILOT STATEMENTS HE REPORTED THAT 'APPARENTLY THE LEFT BRAKE WAS HIT HARDER THAN THE RIGHT.'
On January 21, 1994 at 1141 central standard time, a Cessna 152, N6374M, was substantially damaged during an aborted takeoff at the Tulsa, Oklahoma, Richard L. Jones, Jr. Airport. The student pilot sustained minor injuries. Visual meteorological conditions prevailed for the solo instructional flight. Tower personnel reported that the aircraft was cleared to taxi into position and hold on runway 19R. Shortly after holding, the aircraft initiated a takeoff roll without clearance. The tower instructed the pilot to abort the takeoff. The pilot reported that he heard what he believed to be a clearance for him to takeoff, which he acknowledged. After the aircraft attained minimum flying airspeed, he was instructed to abort the takeoff. He then reduced power and began braking. The pilot reported, "the left brake grabbed harder than the right and I turned toward the ditch." He further stated that the airplane departed the runway, struck a PAPI light, and came to rest in sand. No mechanical malfunctions were reported. In a statement signed by the student pilot dated January 20, 1994, he reported that "apparently the left brake was pushed harder than the right."
THE STUDENT PILOT'S IMPROPER BRAKING TECHNIQUE AND THE RESULTANT FAILURE TO MAINTAIN DIRECTIONAL CONTROL. A FACTOR WAS THE PILOT NOT OBTAINING AN ATC CLEARANCE PRIOR TO TAKEOFF.
