# NTSB SEA04LA007: Cessna 185, N1841R, Trout Lake, WA, October 18, 2003 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 18, 2003, 14:20 local (21:20 UTC) - Place: Trout Lake, WA - Coordinates: 46.002223, -121.524719 - Nearby events: https://openairdocs.org/map.md?lat=46.0022&lon=-121.5247&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report March 2, 2004 - Report: Approved by Office Director - Parties: Hillsboro, Oregon - NTSB case key (mKey): 58197 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA04LA007 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/58197/pdf - Page: https://openairdocs.org/ntsb/SEA04LA007 ## Probable cause The failure of the pilot to maintain directional control of the aircraft during the landing roll. A factor was the wet runway. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - directional control - not maintained, pilot in command (cause) - terrain condition - wet (contributing factor) - Nose over, landing - roll ## Analysis After touching down on the wet runway, the aircraft veered slightly to the right. During landing rollout the aircraft did not respond to left rudder or left wheel braking, but skid marks measuring 200 feet in length indicated the left brake was functioning. After applying heavy braking, the right wheel plowed into the ground causing the aircraft to nose over. A post-accident inspection of the airplane did not indicate a mechanical failure or malfunction. ## Factual narrative On October 18, 2003, approximately 1420 Pacific daylight time, a Cessna 185 single-engine airplane, N1841R, was substantially damaged following a loss of control during landing roll at the Trout Lake Airport (66WA), Trout Lake, Washington. The airplane was registered to and operated by a private individual. The private pilot and his sole passenger were not injured. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 CFR Part 91 personal flight. The local flight departed Trout Lake at 1410. In a telephone interview with the NTSB investigator-in-charge (IIC), and according to the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2), the pilot reported that after a normal touchdown, the aircraft rollout was slightly to the right. The pilot stated the aircraft did not respond to left rudder or left wheel braking, but that the skid marks, which were 200 feet in length, indicated the left brake was functioning. The pilot further reported that he then applied heavy braking, and subsequently the right wheel plowed into the ground, causing the tail to come up and the aircraft nosing over. The pilot reported the runway surface was "slightly" wet. An FAA inspector, who traveled to the accident site, inspected the aircraft and reported that there was no evidence found to indicate a mechanical failure or malfunction. The inspector also reported the aircraft had sustained substantial damage to the rudder and vertical stabilizer. ## Aircraft - Registration: [N1841R](https://openairdocs.org/aircraft/N1841R), registered now, S/N 18502556, built 1974 (OpenAirDocs) - Reported make and model: Cessna 185 - Registry model: [Cessna A185F](https://openairdocs.org/model/cessna-a185f) (registry code 2072821) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18502556 - Airframe hours: 6445 - Engines: Continental IO-520D 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, August 27, 2003, 36 hours before - Departed: 66WA, Trout Lake, WA - Airport: 66WA, Trout Lake Airport, runway 25, 1,800 × 60 ft, grass/turf ## Flight crew As NTSB recorded them.

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.
