# NTSB SEA00LA147: Cessna A185F, N7485C, Tillamook, OR, July 28, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 28, 2000, 12:00 local (19:00 UTC) - Place: Tillamook, OR - Coordinates: 45.460891, -123.709571 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=45.4609&lon=-123.7096&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report September 30, 2003 - Report: Approved by Office Director - Parties: FAA - HILLSBORO FSDO - NTSB case key (mKey): 49860 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA00LA147 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49860/pdf - Page: https://openairdocs.org/ntsb/SEA00LA147 ## Probable cause The pilot's failure to maintain directional control. ## 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) - Nose down, landing - roll ## Analysis The pilot entered a downwind for runway 31 and noted calm winds from a nearby smoke stack and the midfield windsock. He established the aircraft on short final with three notches of flaps and 65 knots of airspeed for a three-point landing. Touchdown on the main wheels occurred just slightly before the tailwheel touchdown. Once on the runway, the pilot applied full aft elevator, raised the manually operated flaps, and applied light braking during which the aircraft suddenly veered left. The pilot reported that rudder control was inadequate, and that applying power worsened the yaw. He then retarded the throttle to idle, applied full up elevator, hard right rudder and hard braking, during which the aircraft continued to yaw left and eventually impacted the right wingtip. The pilot reported that there was no mechanical malfunction with the aircraft during the event. ## Factual narrative On July 28, 2000, approximately 1200 Pacific daylight time, a Cessna A185F, N7485C, registered to Aero Management Group, LLC, and being flown by a private pilot, sustained substantial damage during a loss of control on landing at Tillamook airport, Tillamook, Oregon. The pilot was uninjured. Visual meteorological conditions prevailed and no flight plan had been filed. The flight, which was personal, was operated under 14CFR91, and originated from Hillsboro, Oregon, approximately 1115. The pilot was telephonically interviewed and subsequently submitted a statement on NTSB Form 6120.1/2 (attached) reporting that he departed Hillsboro, Oregon, en route to Tillamook, Oregon. Upon arrival in the Tillamook area he entered a downwind for runway 31, and noted the smoke trail from a nearby sawmill north of the airport ascending vertically indicating negligible winds. After entering downwind, he ascertained calm wind conditions from the mid-field windsock. He reported that he flew a normal approach selecting "three notches" of flaps and slowing to 65 knots on short final for a three-point landing. The pilot further reported, "Touchdown was on [the] mains, just slightly before [the] tailwheel. With [the] control yoke full back, [the] aircraft on all three gear, light braking was applied and flaps retracted. [The] aircraft suddenly veered left. Rudder control was inadequate to counteract. [An] attempt to add power worsened [the] yaw so [the] engine was pulled to idle cut-off. With full up elevator, hard right rudder, and hard braking, [the] aircraft continued to yaw left, skidded on [the] right main, rolled right onto [the] wingtip and slid 20 - 30 feet before pitching forward onto [the] nose. [The] aircraft slid on [its] nose & main gear 2 feet before tipping onto [the] left wingtip and coming to rest on [the] left side of 31." The pilot reported that there was no mechanical malfunction with the aircraft during the event. The aircraft was equipped with manually operated flaps. ## Aircraft - Registration: [N7485C](https://openairdocs.org/aircraft/N7485C), registered now, S/N 18502373, built 1974 (OpenAirDocs) - Reported make and model: Cessna A185F - 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: 18502373 - Airframe hours: 1922 - Engines: Continental IO-520D 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Lachenmeier, Timothy T. - Registered owner: Aero Management Group, LLC. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 1, 2000, 19 hours before - Departed: HIO, HILLSBORO, OR - Destination: S47 - Airport: S47, Tillamook, runway 31, 4,990 × 100 ft, asphalt ## 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.
