He retarded the throttle and attempted to apply toe brakes, but the airplane was equipped with a hand brake instead of toe brakes. The flight instructor reported that the airplane moved toward a hangar at a "rapid speed" as he tried to slow the airplane. The airplane collided with a hangar door, resulting in substantial damage to the airframe. The instructor stated that the time from loss of control to the collision with the hangar was about 2 to 3 seconds. The instructor had 1.9 hours of experience in the accident airplane. The pilots reported that there were no anomalies or malfunctions with the airplane during the accident sequence. ## Factual narrative The non-certificated student pilot reported that, while taxiing to the runway and adjusting the throttle, the engine spooled up and the taxi speed increased. He retarded the throttle and attempted to apply toe brakes. The airplane was equipped with a hand brake instead of toe brakes. The certified flight instructor (CFI) reported that the airplane moved toward a hangar at a "rapid speed" as he tried to slow the airplane. The airplane collided with a hangar door, resulting in substantial damage to the airframe. The CFI stated that the time from loss of control to the collision with the hangar was about two to three seconds. The CFI had 1.9 hours of experience in the accident airplane. The pilots reported that there were no anomalies or malfunctions with the airplane during the accident sequence. ## Aircraft - Registration: [N701CF](https://openairdocs.org/deregistered/N701CF-2013-08-05), registration cancelled 2013-08-05, S/N 237 07, built 2007 (OpenAirDocs) - Reported make and model: AEROPRO CZ EUROFOX LSA - Registry model: [Aeropro CZ EUROFOX LSA](https://openairdocs.org/model/aeropro-cz-eurofox-lsa) (registry code 0600024) (OpenAirDocs) - Registry engine: [Rotax 912ULS series](https://openairdocs.org/engine/rotax-912uls-series) (registry code 55572, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 237 07 - Airframe hours: 791 - Engines: ROTAX 912ULS 100 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Airworthiness certificate: Special, Experimental light sport (Special) - Last inspection: 100 hour, May 9, 2011 - Departed: GIF, Winter Haven, FL - Destination: GIF, Winter Haven, FL - Airport: GIF, Gilbert Airport, runway 05, 5,005 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
