# NTSB SEA02LA078: American Champion 8KCAB, N86AA, Davenport, WA, May 2, 2002 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: May 2, 2002, 12:30 local (19:30 UTC) - Place: Davenport, WA - Coordinates: 47.67052, -118.190818 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=47.6705&lon=-118.1908&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report October 24, 2002 - Report: Approved by Office Director - Parties: FAA-FSDO - NTSB case key (mKey): 54641 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA02LA078 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/54641/pdf - NTSB docket: https://data.ntsb.gov/Docket?ProjectID=54641 - Page: https://openairdocs.org/ntsb/SEA02LA078 ## Probable cause The pilot's failure to adequately compensate for the wind conditions during takeoff. Gusting wind was a factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - roll/run - weather condition - gusts (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - On ground/water encounter with terrain/water, takeoff - roll/run ## Analysis The pilot reported that he was taking off from runway 23 in 20 to 25 knot winds with gusts to 30 plus from 200 degrees. Just as the aircraft was lifting off the runway, a strong gust of wind picked up the left wing. The pilot tried to lower the left wing, however the wing continued to raise and the right wing contacted the runway surface. The aircraft cart wheeled onto its nose then struck the tail, coming to rest upright off the right side of the runway. The pilot reported no mechanical failures or malfunctions with the aircraft at the time. ## Factual narrative On May 2, 2002, about 1230 Pacific daylight time, an American Champion 8KCAB, N86AA, registered to and operated by the pilot as a 14 CFR Part 91 personal flight, collided with the terrain during the takeoff ground roll from the Davenport Airport, Davenport, Washington. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft was substantially damaged and the commercial pilot and his passenger were not injured. The aircraft was departing for Chelan, Washington. During a telephone interview and subsequent written statement, the pilot reported that during the takeoff ground roll from runway 23 with a 20 to 25 knot wind with gusts to 30 plus knots from 200 degrees, the aircraft traveled from behind a row of hangars that parallel the runway. At this point, as the aircraft was just lifting off the runway, a strong gust of wind picked up the left wing. The pilot tried to lower the left wing, however the wing continued to raise and the right wing contacted the runway surface. The aircraft "cart wheeled" onto its nose then struck the tail, coming to rest upright off the right side of the runway. The pilot reported no mechanical failures or malfunctions with the aircraft at the time. The weather reported at Spokane, Washington, 26 nautical miles east of Davenport, was reporting at 1156, wind from 220 degrees at 19 knots, gusting to 27 knots. ## Aircraft - Registration: [N86AA](https://openairdocs.org/deregistered/N86AA-2002-06-26), registration cancelled 2002-06-26, S/N 773-96 (OpenAirDocs) - Reported make and model: American Champion (ACAC) 8KCAB - Registry model: [American Champion 8KCAB](https://openairdocs.org/model/american-champion-8kcab) (registry code 2121000) (OpenAirDocs) - Category: Airplane - Serial number: 773-96 - Engines: Lycoming IO-360-H1B 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Stanley N.

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.
