Factors include a slush-covered runway. ## Analysis The pilot attempted to land on a 1,500 foot grass strip. He said that the airplane touched down 'on the numbers', but he was unable to stop the aircraft due to water and slush on the airstrip. He reported that the aircraft was 'hydroplaning across the grass' and when he applied the aircraft's brakes they 'locked up.' The pilot elected to initiate a go-around. Shortly after lift-off, the aircraft's main wheels collided with a four-foot deep snow bank at the departure end of runway. The nose gear was torn from the aircraft and the fuselage was damaged. The pilot reported no mechanical failures or malfunctions with the aircraft prior to the accident. ## Factual narrative On February 13, 1999, about 1405 mountain standard time, a Cessna 182A, N3753D, registered to and operated by the pilot as a 14 CFR 91 personal flight, was substantially damaged during the landing rollout at the Trapper Creek Airport, Connor, Montana. Visual meteorological conditions prevailed and no flight plan was filed for the local flight. The private pilot and his passenger were not injured. There was no fire and no report of an ELT actuating. The flight originated from the Trapper Creek Airport approximately one hour before the accident. During a telephone interview and written statement, the pilot stated he attempted to land on a 1,500 foot grass strip. The pilot then stated that the airplane touched down "on the numbers", but he was unable to stop the aircraft due to water and slush on the airstrip. The pilot reported that the aircraft was "hydroplaning across the grass" and when he applied the aircraft's brake's they "locked up." The pilot elected to initiate a go-around and shortly after lift-off the aircraft's main wheels collided with a four-foot deep snow bank at the departure end of the runway. The nose gear was torn from the aircraft and the fuselage was damaged. The pilot reported no mechanical failures or malfunctions with the aircraft prior to the accident. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - On ground/water encounter with terrain/water, landing - aborted - airport facilities,runway/landing area condition - slush covered (contributing factor) - go-around - delayed, pilot in command (cause) ## Aircraft - Registration: [N3753D](https://openairdocs.org/deregistered/N3753D-2013-04-22), registration cancelled 2013-04-22, S/N 34453, built 1957 (OpenAirDocs) - Reported make and model: Cessna 182A - Registry model: [Cessna 182A](https://openairdocs.org/model/cessna-182a) (registry code 2072704) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 34453 - Airframe hours: 4211 - Engines: Continental O-470L 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Frost, Dean H. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 22, 1998, 31 hours before - Departed: MT30 - Airport: MT30, Trapper Creek, runway 16, 1,500 × 60 ft, grass/turf ## Flight crew As NTSB recorded them.

Acft was unable to stop after landing due to the rwy being slick, and the acft ran into a snow bank on the end of the rwy. Other circumstances are unknown.… From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date; the registry's history has gaps, so older matches can be wrong.
