REPORT QUALITY ASSURANCE TUTORIALSample Preparatory Step 2 - Markup. (Underline reported name of each actor and what actor reportedly did.) Go to Step 3 inferred events. Again pilot (X) made an approach at 90 mph and 25deg. flaps. He stated that he touched down approximately 50 feet past the runway threshold numbers. He raised the flaps, then proceeded to apply the toe brakes. At this point, he claims the aircraft pulled to the right sharply, and he straightened its path by use of rudder. Mr. (X) now attempted stopping the aircraft by applying the hand brake and foot brakes. This time the aircraft started off toward the left of runway centerline. N4668J went off the departure end of the runway, left of centerline. His estimated speed at this time was approximately 30 mph. He traveled through 10 feet of grass, then his main landing gear struck a small trench, the aircraft then struck a dirt pile where it came to rest. Pilot and passengers exited N4668J without injury. Examination of the accident scene of 11-29-79 by EA-GADO-11 maintenance and operations personnel disclosed the following: Runway 18 showed one tire skid mark which measured approximately 300 feet long. It started on runway centerline and traveled to the end, gradually traveling toward the left edge. From the end of the runway hardtop, the skid mark went through the grass, across a 14 inch wide trench, and terminated at the dirt pile. Examination of N4668J was conducted on 11-29-79 in a hangar at (X) Airport where the aircraft had been moved to protect it from vandalism. 'The left wing was deformed, buckled and wrinkled at the rear spar, starting at the wing root and traveling outboard for approximately 7 feet. Rivets were and skin wrinkled on the left wing lower side at the area behind the left main gear well. The right main landing gear disc brake assembly had failed at the area were it is welded to the brake disc housing. This area was badly corroded to the point where the metal in this area is paper thin. Both propeller tips were bent 90deg. and one bend had a crack 1-1/2 inches long. Nose wheel gear was torn and bent. N4668J had sustained major structural damage to the left wing.
