As the airplane approached the end of the runway, the pilot realized that the airplane would not stop in time and used right engine differential power to turn left and avoid a 150-foot drop-off located at the end of the runway. The airplane veered left off the end of the runway onto a gravel area. When the airplane entered the gravel area the right main landing gear collapsed, resulting in substantial damage to the outboard edge of the aileron, and damage to the landing gear and top of the inboard wing. The pilot reported no preimpact mechanical malfunctions with the airplane. ## Factual narrative The pilot reported that it had just rained on the 2,695-foot-long runway that he intended to land on. During the landing roll, the pilot applied moderate braking but he did not sense that the airplane was decelerating sufficiently. The pilot stated that his knowledge of this airport made him aware of a 150 foot drop off located at the end of the runway. With the end of the runway approaching, the pilot elected to turn left off the runway and he used the right engine to assist the turn. The airplane veered left off the end of the runway onto a gravel area. When the airplane entered the gravel area the right main landing gear collapsed, resulting in substantial damage to the outboard edge of the aileron, and damage to the landing gear and top of the inboard wing. The pilot said there were no preimpact mechanical malfunctions or failures. ## Aircraft - Registration: [N601FD](https://openairdocs.org/deregistered/N601FD-2013-08-19), registration cancelled 2013-08-19, S/N TC-1772, built 1974 (OpenAirDocs) - Reported make and model: BEECH 95-B55 (T42A) - Registry model: [Beech 95-B55 (T42A)](https://openairdocs.org/model/beech-95-b55-t42a) (registry code 1152706) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: TC-1772 - Airframe hours: 4268 - Engines: CONT MOTOR IO-470 SERIES 300 horsepower reciprocating; CONT MOTOR I0-470 SERIES 300 horsepower reciprocating - Damage: Substantial damage - Flight: Business, Part 91 - Operator: Beachmont LLC - Registered owner: Beachmont LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, December 10, 2010, 48 hours before - Departed: KSZT, Sandpoint, ID - Destination: 63S, Colville, WA - Airport: 63S, Colville Municipal Airport, runway 19, 2,695 × 40 ft, asphalt ## Flight crew As NTSB recorded them.
