Aircraft Accident/Incident Report

Newberg, Oregon 97132
Monday, July 13, 1998 11:49 PDT

NTSB Narrative Summary Released at Completion of Accident

Following touchdown on the runway center line, the homebuilt tail-wheel equipped Cygnet SF-2A drifted left and the pilot-in-command applied right rudder to correct. The aircraft then veered to the right and, in spite of hard left brake and rudder application, departed the north edge of the runway, impacting a fence post. The accident flight was the pilot-in-command's first solo in the toe-brake equipped aircraft. She did possess approximately 100 hours in the tail-wheel equipped Citabria. This aircraft, however, was equipped with heel-brakes, rather than toe-brakes.

NTSB Probable Cause Narrative

The pilot-in-command's failure to maintain directional control. Factors contributing were the pilot-in-command's lack of experience in make of aircraft (i.e., use of toe brakes) and the fence post.
