What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Airplane, multiengine training flight terminated at training base with simulated engine out approach and landing. Engine out simulation was terminated on short final and normal touchdown was made by student pilot. Flight instructor commanded pilot flying to apply braking after touch down in order to turn off at taxiway mid-field. The aircraft then veered to the left and the instructor verbally commanded the pilot flying to get off the brakes. The instructor, not having wheel brakes from the right seat then applied right rudder to compensate for swerve. Exchange of flight controls was then made to the instructor while continuing to apply full right rudder. The instructor was of the opinion that the left tire was flat due to the continuation of the left swerve. With full right rudder, the aircraft continued off the runway (to the left) onto the sod area adjacent the runway (rwy 32) whereupon; the left main gear struck uneven terrain causing the left main gear to collapse. The aircraft continued for another few yards turning to the left before coming to a stop. Skid marks were observed on the runway approximately 1,400 feet from the approach end continuing for approximately 345 yards to the point where the right main gear had left a gouge in the sod area to the west of the runway. The instructor suspects that the wheel break was locked on the left wheel shortly after touch down whereupon the tire sustained damage causing it to go flat. A post incident inspection of the tire and brake assembly revealed a flat spot and hole in the left tire. A post incident test of the left brake revealed it to be functioning as designed. Iic concludes that student pilot application of braking was excessive following touch down or, the brake callipers on the left wheel assembly stuck in the applied position.
As the FAA filed it
(-23) AIRPLANE, MULTIENGINE TRAINING FLIGHT TERMINATED AT TRAINING BASE WITH SIMULATED ENGINE OUT APPROACH AND LANDING. ENGINE OUT SIMULATION WAS TERMINATED ON SHORT FINAL AND NORMAL TOUCHDOWN WAS MADE BY STUDENT PILOT. FLIGHT INSTRUCTOR COMMANDED PILOT FLYING TO APPLY BRAKING AFTER TOUCH DOWN IN ORDER TO TURN OFF AT TAXIWAY MID-FIELD. THE AIRCRAFT THEN VEERED TO THE LEFT AND THE INSTRUCTOR VERBALLY COMMANDED THE PILOT FLYING TO GET OFF THE BRAKES. THE INSTRUCTOR, NOT HAVING WHEEL BRAKES FROM THE RIGHT SEAT THEN APPLIED RIGHT RUDDER TO COMPENSATE FOR SWERVE. EXCHANGE OF FLIGHT CONTROLS WAS THEN MADE TO THE INSTRUCTOR WHILE CONTINUING TO APPLY FULL RIGHT RUDDER. THE INSTRUCTOR WAS OF THE OPINION THAT THE LEFT TIRE WAS FLAT DUE TO THE CONTINUATION OF THE LEFT SWERVE. WITH FULL RIGHT RUDDER, THE AIRCRAFT CONTINUED OFF THE RUNWAY (TO THE LEFT) ONTO THE SOD AREA ADJACENT THE RUNWAY (RWY 32) WHEREUPON; THE LEFT MAIN GEAR STRUCK UNEVEN TERRAIN CAUSING THE LEFT MAIN GEAR TO COLLAPSE. THE AIRCRAFT CONTINUED FOR ANOTHER FEW YARDS TURNING TO THE LEFT BEFORE COMING TO A STOP. SKID MARKS WERE OBSERVED ON THE RUNWAY APPROXIMATELY 1,400 FEET FROM THE APPROACH END CONTINUING FOR APPROXIMATELY 345 YARDS TO THE POINT WHERE THE RIGHT MAIN GEAR HAD LEFT A GOUGE IN THE SOD AREA TO THE WEST OF THE RUNWAY. THE INSTRUCTOR SUSPECTS THAT THE WHEEL BREAK WAS LOCKED ON THE LEFT WHEEL SHORTLY AFTER TOUCH DOWN WHEREUPON THE TIRE SUSTAINED DAMAGE CAUSING IT TO GO FLAT. A POST INCIDENT INSPECTION OF THE TIRE AND BRAKE ASSEMBLY REVEALED A FLAT SPOT AND HOLE IN THE LEFT TIRE. A POST INCIDENT TEST OF THE LEFT BRAKE REVEALED IT TO BE FUNCTIONING AS DESIGNED. IIC CONCLUDES THAT STUDENT PILOT APPLICATION OF BRAKING WAS EXCESSIVE FOLLOWING TOUCH DOWN OR, THE BRAKE CALLIPERS ON THE LEFT WHEEL ASSEMBLY STUCK IN THE APPLIED POSITION.
