29 Oct 2019: Cessna 170 B — Perry Aeronautical Services Llc — Albuquerque, NM

Albuquerque, NM, United States

On 29 Oct 2019, a Cessna 170 B operated by Perry Aeronautical Services Llc was involved in an aviation accident near Albuquerque, NM. No fatalities were reported. Investigators recorded the probable cause as: The pilot receiving instruction's failure to maintain directional control and his inadvertent left brake pedal application during the landing roll, which resulted in a runway excursion and ground-loop. This summary draws on records from NTSB; 12 related events involving the same aircraft type or operator are linked below.

During tailwheel endorsement training, a student pilot aborted a landing, overcorrected with rudder, and inadvertently applied brake, causing the aircraft to veer off the runway. The right wing struck the ground three times before the aircraft came to rest upright, resulting in substantial damage.

Flight Details

The pilot receiving instruction for a tailwheel endorsement reported that he and the instructor were practicing touch-and-go landings and takeoffs on an asphalt runway. The aircraft was equipped with toe brakes.

Sequence of Events

After landing, the pilot added power to abort the landing and applied right rudder as the airspeed accelerated to 30 knots. He held the right rudder pedal application for too long, causing the airplane to veer to the right. He corrected by applying left rudder but overcorrected. The flight instructor then took control and applied full deflection of the right rudder.

The airplane did not respond to the instructor's right rudder input, so the instructor applied left aileron. The pilot receiving instruction kept his feet on the pedals and inadvertently applied left brake. The airplane was side-loaded to the right, and the right wing struck the ground. The instructor held his inputs to direct the airplane right, but the right wing struck the ground a second time before the aircraft exited the left side of the runway.

The airplane's heading was about 60 degrees left of the runway heading. The wheels dug into the dirt on the left side of the runway, the elevator struck the ground, and the right wing struck the ground a third time before the airplane came to rest upright.

Damage and Findings

The airplane sustained substantial damage to the right wing and the right elevator. The pilot receiving instruction, who was also the aircraft owner, reported that he had installed removable 1-inch blocks on the lower portion of the rudder/brake pedals to reduce required ankle deflection and allow applying rudder controls with less likelihood of simultaneously applying brake inputs. The pilot reported that there were no mechanical malfunctions or failures that would have precluded normal operation.
