Incident Overview
A flight instructor was at the controls of a Luscombe aircraft at Nampa Airport. The purpose of the flight was to familiarize himself with the aircraft so that he could later provide instruction to the new owner during a flight to Texas. After a short local flight, the instructor performed a touch-and-go landing and then entered the traffic pattern for a second landing.
Sequence of Events
During the landing roll of the second landing, the aircraft began to veer from side to side. The pilot described the motion as an "aggravated pilot induced oscillation." In response, he applied full aft stick to increase tailwheel authority. As he pulled the stick aft, he inadvertently added left aileron, which raised the right wing. The aircraft then started to veer off the right side of the runway. The pilot applied full left rudder, significant left brake, and full power, but these inputs were insufficient to correct the path. The aircraft departed the right side of the runway and encountered soft terrain, causing the left main landing gear to collapse.
Pilot Remarks
In a telephone conversation with the NTSB, the pilot stated that he had been "slow to recognize" the situation that led to the loss of control. Investigation revealed that the pilot had a total of one hour of previous experience in a Luscombe aircraft.
