# NTSB SEA04LA153: Piper PA-24-260, N9394P, Redmond, OR, August 1, 2004 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 1, 2004, 16:47 local (23:47 UTC) - Place: Redmond, OR - Coordinates: 44.253887, -121.149719 - Nearby events: https://openairdocs.org/map.md?lat=44.2539&lon=-121.1497&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report April 28, 2005 - Report: Approved by Office Director - Parties: FAA-FSDO - NTSB case key (mKey): 59816 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA04LA153 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/59816/pdf - Page: https://openairdocs.org/ntsb/SEA04LA153 ## Probable cause Unknown malfunction of the landing gear system for undetermined reasons that resulted in a gear collapse during landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, landing - landing gear - malfunction (cause) - Gear collapsed, landing ## Analysis On landing, just as the airplane touched down, the landing gear collapsed resulting in substantial damage to the airframe. The pilot reported that he lowered the landing gear after entering the downwind for the landing runway. He stated that after lowering the gear, the "down and locked" indicator light illuminated confirming the gear was down. He further stated the landing flare was normal, however the airplane continued to settle, eventually landing with the gear in the up position. Post accident evaluation of the landing gear system, to include a gear swing, revealed no anomalies that would have prevented the landing gear from fully extending to the down and locked position. ## Factual narrative On August 1, 2004, at 1647 Pacific daylight time, a Piper PA-24-260 (Comanche), N9394P, sustained substantial damage following a wheels up landing at Roberts Field Airport, Redmond, Oregon. The airplane, which is owned by the pilot, was being operated as a visual flight rules (VFR) cross-country flight under the provisions of Title 14, CFR Part 91, when the accident occurred. The private pilot and two passengers aboard the airplane were not injured in the accident. Visual meteorological conditions prevailed for the cross-country flight that originated at Tacoma Narrows (KTIW), Tacoma, Washington. During a telephone conversation with the National Transportation Safety Board IIC, on August 4, the pilot reported that he lowered the landing gear after entering the downwind for the landing runway. He stated that after lowering the gear, the "down and locked" indicator light illuminated confirming the gear was down. He further stated the landing flare was normal, however the airplane continued to settle, eventually landing with the gear in the up position. Post accident evaluation of the landing gear system, to include a gear swing, revealed no anomalies that would have prevented the landing gear from fully extending to the down and locked position. ## Aircraft - Registration: [N9394P](https://openairdocs.org/aircraft/N9394P), registered now, S/N 24-4897, built 1969 (OpenAirDocs) - Reported make and model: Piper PA-24-260 - Registry model: [Piper PA-24-260](https://openairdocs.org/model/piper-pa-24-260) (registry code 7102406) (OpenAirDocs) - Registry engine: [Lycoming TI0-540 series](https://openairdocs.org/engine/lycoming-ti0-540-series) (registry code 41533, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: 24-4897 - Airframe hours: 4244 - Engines: Lycoming IO-540 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Andreas G.
