# NTSB LAX00LA140: Stuart RAF 2000 GTX SE, N60739, Overton, NV, March 27, 2000 - Type: NTSB accident investigation - Classification: Accident · Fatal · Limited investigation · Final report - Date: March 27, 2000, 11:24 local (19:24 UTC) - Place: Overton, NV - Coordinates: 36.389373, -114.369445 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=36.3894&lon=-114.3694&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: Fatal - Injuries: 1 fatal - Status: Completed, report December 14, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 51205 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX00LA140 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/51205/pdf - Page: https://openairdocs.org/ntsb/LAX00LA140 ## Probable cause Failure of the pilot to obtain/maintain aircraft control. A factor in the accident was the pilot's inexperience in rotorcraft. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, approach - vfr pattern - base leg/base to final - aircraft control - not obtained/maintained, pilot in command (cause) - lack of experience, pilot in command (contributing factor) - porpoise/pilot-induced oscillation - encountered, pilot in command - In flight collision with terrain/water, descent - uncontrolled - terrain condition - runway ## Analysis The gyrocopter was seen porpoising over the runway when it became inverted and impacted the runway from 100 feet agl. The gyrocopter was destroyed in the ensuing post-impact fire. The pilot had indicated to a hangar mate and his spouse that this was the maiden flight. The pilot had purchased the gyrocopter a year earlier and conducted only taxi runs and engine ground runs during that time. A witness saw him take off and immediately saw the gyrocopter porpoising. The gyrocopter left the airport environment for a few minutes and then made a turn back towards the runway. The porpoising was observed to have stopped, and then started up again with an increase in intensity. A witness heard the engine power back and then saw the gyrocopter become inverted and impact the runway. Another witness stated that he saw the gyrocopter takeoff and noted that the main rotor blades appeared to be turning slowly. A review of the pilot's airman's certificate revealed that he did not hold a rotorcraft rating. ## Factual narrative On March 27, 2000, at 1124 hours Pacific standard time, a Stuart RAF 2000 GTX SE, N60739, became inverted and impacted the runway at Perkins Field Airport, Overton, Nevada. The experimental gyrocopter, operated under 14 CFR Part 91, was destroyed in a post-impact fire. The private pilot/owner was fatally injured. Visual meteorological conditions existed for the local area personal flight and no flight plan was filed. The flight departed the airport a few minutes prior to the accident and was scheduled to terminate there. One witness had talked to the pilot prior to takeoff. He stated that the pilot had told him this was his maiden flight. The witness watched him take off and immediately saw the gyrocopter porpoising in the air. He watched him leave the airport environment and then make a turn back towards the runway. The porpoising stopped; then it started again. As the gyrocopter flew over the runway the porpoising increased in severity. The witness stated that the pilot reduced power during this portion of the flight. The final porpoise that he saw placed the gyrocopter in an inverted position. The witness then saw the gyrocopter fall inverted to the ground from about 100 feet agl. Another witness saw the gyrocopter takeoff and noted that the main rotor blades were turning slowly. He didn't think anything of it and continued on with his next stop. As he was departing from his delivery he noted that the gyrocopter was over the airport and then saw it crash. PERSONNEL INFORMATION The pilot's logbook was not available for review by the Safety Board. A review of the Federal Aviation Administration (FAA) Airman's Certification records revealed that the pilot was issued a private pilot certificate on February 2, 1969, with ratings for airplane single engine land and instrument. A review of the FAA Medical Certification records revealed that the pilot held a third-class medical certificate issued on October 28, 1999, with limitations for near vision. At that time he reported his total flight time to be 5,000 hours. AIRCRAFT INFORMATION Review of the gyrocopter logbook disclosed that on June 29, 1998, a Special Airworthiness Certificate was issued. The next condition inspection was due on July 1, 1999. MEDICAL AND PATHOLOGICAL INFORMATION The Clark County Coroner, Las Vegas, Nevada, conducted a post mortem examination of the pilot. The toxicological analysis was performed by the FAA Civil Aeromedical Institute, Oklahoma City, Oklahoma. The tests were negative for alcohol, all screened drug substances, Carbon Monoxide, and Cyanide. According to the spouse, the pilot had flown helicopters for the past 10 years. He had purchased the gyrocopter last year from a private individual in Oregon. The pilot traveled to Oregon to transport the gyrocopter back to Nevada via a trailer. Since that time he had only ground run the engine and conducted taxi runs, he had not flown it. The accident flight was to be the maiden flight. According to an FAA inspector, the pilot did not hold a rotorcraft category rating. ## Aircraft - Registration: [N60739](https://openairdocs.org/deregistered/N60739-2001-04-10), registration cancelled 2001-04-10, S/N H2-97-8-312 (OpenAirDocs) - Reported make and model: Stuart RAF 2000 GTX SE (RAF 2000 G) - Registry model: [Stuart Donald L RAF 2000 GTX SE](https://openairdocs.org/model/stuart-donald-l-raf-2000-gtx-se) (registry code 05605LE) (OpenAirDocs) - Category: Gyroplane, amateur-built - Serial number: H2-97-8-312 - Engines: Subaru EJ22 100 horsepower reciprocating - Damage: Destroyed - Fire: On-Ground - Flight: Personal, Part 91 - Registered owner: Glenn E.
