# NTSB FTW01LA189: Donald A Chiasson FP-404, N404DC, Port Allen, LA, August 10, 2001 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 10, 2001, 18:30 UTC - Place: Port Allen, LA - Coordinates: 30.533056, -91.149444 - Nearby events: https://openairdocs.org/map.md?lat=30.5331&lon=-91.1494&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report April 29, 2003 - Report: Approved by Office Director - Parties: FEDERAL AVIATION ADMINISTRATION - NTSB case key (mKey): 53102 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW01LA189 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/53102/pdf - Page: https://openairdocs.org/ntsb/FTW01LA189 ## Probable cause The loss of engine power for undetermined reason. A contributing factor was the lack of suitable terrain 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, landing - flare/touchdown - reason for occurrence undetermined (cause) - Forced landing, emergency descent/landing - In flight collision with object, emergency landing - terrain condition - crop - terrain condition - none suitable (contributing factor) ## Analysis The pilot of the homebuilt airplane reported that the engine began to run rough while maneuvering at about 1,000 feet above the ground. The engine subsequently lost power and seized. The pilot executed a forced landing to a sugar cane field. The reason for the loss of engine power could not be determined. ## Factual narrative On August 10, 2001, approximately 1830 central daylight time, a Donald Chiasson FP-404 homebuilt experimental airplane, N404DC, registered to and operated by the pilot, was substantially damaged when it impacted terrain during a forced landing following a loss of engine power near Port Allen, Louisiana. The non-instrument rated private pilot, sole occupant of the airplane, was not injured. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The flight originated from the Omni Field (LA46), near a Port Allen, Louisiana, approximately 1800 local. The 525-hour pilot reported to the FAA inspector, that while in level flight at about 800 feet above the ground, the 52 horsepower Rotax 503 engine began to run rough and lose RPM. A few seconds later, while the pilot was attempting to return to the airport, the engine lost power and seized. The pilot elected to execute forced landing to a sugar cane field. The pilot was able to egress the airplane unassisted. There was no fire. Examination of the airplane revealed structural damage to the airframe, both main landing gears were damaged, the engine mounts were bent, and one propeller blade was fractured. The airplane had accumulated a total of 11.6 hours since it was built by the pilot. The reason for the loss of engine power could not be determined. ## Aircraft - Registration: [N404DC](https://openairdocs.org/deregistered/N404DC-2018-01-18), registration cancelled 2018-01-18, S/N 4180, built 2000 (OpenAirDocs) - Reported make and model: Donald A Chiasson FP-404 - Registry model: [Chiasson Donald A FP-404](https://openairdocs.org/model/chiasson-donald-a-fp-404) (registry code 05607RO) (OpenAirDocs) - Registry engine: [Bombardier ROTAX (ALL)](https://openairdocs.org/engine/bombardier-rotax-all) (registry code 09050, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 4180 - Airframe hours: 12 - Engines: Rotax 503 52 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Donald A.

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.
