# NTSB LAX00LA001: Ismari Canard C3A, N4526W, Henderson, NV, October 2, 1999 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 2, 1999, 08:45 local (15:45 UTC) - Place: Henderson, NV - Coordinates: 36.040863, -114.929176 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=36.0409&lon=-114.9292&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report April 25, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 47550 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX00LA001 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/47550/pdf - Page: https://openairdocs.org/ntsb/LAX00LA001 ## Probable cause A partial loss of engine power for undetermined nonmechanical reasons. A contributing factor was the rough nature of the terrain used for the forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - nonmechanical, takeoff - initial climb - reason for occurrence undetermined (cause) - Forced landing, emergency landing after takeoff - On ground/water encounter with terrain/water, landing - flare/touchdown - terrain condition - rough/uneven (contributing factor) ## Analysis About 100 feet above ground level during initial climb, the experimental airplane's engine began vibrating, sputtering, and losing power. The pilot adjusted the mixture and throttle controls, but was unable to regain sufficient rpm to sustain flight. The pilot made a forced landing on rough desert terrain, about 1 mile from the departure airport. During the subsequent engine examination, no evidence of case or cylinder damage was noted. Oil was found on the dipstick, the carburetor was intact, and the throttle control was secure. The reason for the partial loss of engine power was not determined. ## Factual narrative On October 2, 1999, about 0845 hours Pacific daylight time, an experimental Ismari Canard C3A, N4526W, owned and operated by the pilot, experienced a partial loss of engine power during initial climb from the Henderson, Nevada, airport. The commercial pilot made a forced landing in rough terrain, and the homebuilt airplane was substantially damaged. The personal flight was conducted under the provisions of 14 CFR Part 91. The pilot was not injured. Visual meteorological conditions prevailed at the time of the local area flight, and no flight plan was filed. The flight, which lasted about 3 minutes, was originating at the time of the accident. The pilot reported that upon climbing 100 feet above ground level the engine began vibrating, sputtering, and losing power. Unable to resolve the problem by adjusting the mixture and throttle controls, and with reduced rpm, the pilot was unable to maintain flight. He made a forced landing in desert terrain, about 1 mile southwest of Henderson. The Federal Aviation Administration (FAA) coordinator performed a visual, external examination of the engine. No evidence of case or cylinder damage was noted. Oil was present on the dipstick, and the carburetor was intact without any apparent damage. The throttle control was found intact. ## Aircraft - Registration: [N4526W](https://openairdocs.org/deregistered/N4526W-2000-02-17), registration cancelled 2000-02-17, S/N 01 (OpenAirDocs) - Reported make and model: Ismari CANARD C3A - Registry model: [Ismari Donald L CANARD C3A](https://openairdocs.org/model/ismari-donald-l-canard-c3a) (registry code 05644HY) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 01 - Airframe hours: 638 - Engines: Revmaster 2100D 65 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Donald L.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
