# NTSB SEA98LA032: Cessna 180, N180AJ, Sun Valley, ID, January 31, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: January 30, 1998, 18:38 local (Jan 31, 1998, 01:38 UTC) - Place: Sun Valley, ID - Coordinates: 43.770671, -114.619766 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=43.7707&lon=-114.6198&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report December 8, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 42752 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA98LA032 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/42752/pdf - Page: https://openairdocs.org/ntsb/SEA98LA032 ## Probable cause the pilot's inadvertent actuation of the parking brake. ## Analysis The pilot stated that he had landed earlier on a plowed runway with hard-packed snow and ice surface conditions. He believed that while taxiing for turnaround at the end of the runway, the right-hand brake apparently became hydraulically locked due to engagement of the parking brake mechanism on that side. He stated that at no time was the parking brake handle pulled. He said his takeoff on the icy runway seemed normal, and he was completely unaware of the locked condition of the brake at that time. Upon touchdown at Hailey, the airplane immediately veered violently to the right and the brake remained locked. The airplane swerved to the right before nosing over. Investigation determined that the parking brake locking lever on the right brake cylinder was in its overcenter position, locking the brake. ## Factual narrative On January 30, 1998, approximately 1838 mountain standard time, a Cessna 180, N180AJ, sustained substantial damage when it nosed over during the landing roll at Friedman Memorial Airport, Hailey, Idaho.

Visual meteorological conditions prevailed at the time of the accident. There was no report of the ELT actuating.

Upon touchdown at Hailey, the airplane immediately veered violently to the right and the brake remained locked. The airplane swerved to the right before nosing over. Investigation determined that the parking brake locking lever on the right brake cylinder was in its overcenter position, locking the brake. The pilot reported that he never used the parking brake on this airplane. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Nose over, landing - roll - parking brakes - inadvertent use, pilot in command (cause) ## Aircraft - Registration: [N180AJ](https://openairdocs.org/deregistered/N180AJ-2022-03-21), registration cancelled 2022-03-21, S/N 31229, built 1954 (OpenAirDocs) - Reported make and model: Cessna 180 - Registry model: [Cessna 180](https://openairdocs.org/model/cessna-180) (registry code 2072602) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 31229 - Airframe hours: 4820 - Engines: Continental O-470K 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Kevin R.
