# NTSB SEA00LA134: Cessna 182, N6473A, Snohomish, WA, July 15, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 15, 2000, 10:30 local (17:30 UTC) - Place: Snohomish, WA - Coordinates: 47.85057, -122.090553 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=47.8506&lon=-122.0906&mi=10 - Phase of flight: [Taxi](https://openairdocs.org/ntsb-phases/250) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 5 uninjured - Status: Completed, report May 9, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 49736 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA00LA134 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49736/pdf - Page: https://openairdocs.org/ntsb/SEA00LA134 ## Probable cause The right main landing gear failed for undetermined reasons. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Gear collapsed, taxi - reason for occurrence undetermined (cause) ## Analysis The pilot reported that she taxied the aircraft to the grass covered run-up area in preparation for takeoff. As the aircraft moved over the grass, a 'snapping' sound was heard and the aircraft 'tilted back and to the right.' The right wing and right side stabilizer contacted the ground. Inspection of the right side landing gear revealed that the right landing gear spring failed at the mating area of the outside support, located inside the aircraft fuselage. After the accident, and prior to NTSB or FAA notification, recovery personnel welded the gear leg back into place in order to move the aircraft from the run-up area. ## Factual narrative On July 15, 2000, about 1030 Pacific daylight time, a Cessna 182, N6473A, registered to the owner of Snohomish Parachute Center as a 14 CFR Part 91 parachute drop operation, broke the right main landing gear leg while taxiing for takeoff at Harvey Field, Snohomish, Washington. Visual meteorological conditions prevailed and no flight plan was filed. The aircraft was substantially damaged and the commercial pilot and her four passengers (parachutists) were not injured. In a written statement, the pilot reported that she taxied the aircraft to the run-up area in preparation for takeoff on runway 32. The run-up area is grass covered. As the aircraft moved over the grass, a "snapping" sound was heard and the aircraft "tilted back and to the right." The pilot shut the engine down and the occupants exited the aircraft. Upon inspection of the aircraft, it was found that the right side main landing gear leg broke and penetrated the cabin wall. The right wing and right side horizontal stabilizer subsequently contacted the ground. The owner of the aircraft reported that in order to move the aircraft off of the run-up area, the gear leg was welded back into place. This was done prior to notification of the accident, and before National Transportation Safety Board or Federal Aviation Administration inspection to determine the failure mode. A Federal Aviation Administration Inspector from the Seattle, Washington, Flight Standards District Office, inspected the aircraft and reported that p/n: 0741009-4 - right landing gear spring failed at the mating area of p/n: 0541121-2 - landing gear outside support, located inside the aircraft fuselage. ## Aircraft - Registration: [N6473A](https://openairdocs.org/aircraft/N6473A), registered now, S/N 33273, built 1956 (OpenAirDocs) - Reported make and model: Cessna 182 - Registry model: [Cessna 182](https://openairdocs.org/model/cessna-182) (registry code 2072702) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 33273 - Airframe hours: 14306 - Engines: Continental O-470-SO 285 horsepower reciprocating - Damage: Substantial damage - Flight: Part 91 - Registered owner: Snohomish Parachute Center - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 15, 2000, 61 hours before - Airport: S43, Harvey Field, runway 32, 2,660 × 36 ft, asphalt ## Flight crew As NTSB recorded them.

(-23) While taxing onto grass at Harvey field in Snohomish Washington, the right landign gear support failed. Inspection at the owners facility revealed p/n… From the NTSB's public API. 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.
