# NTSB LAX05LA251: Cessna 210A, N9468X, San Diego, CA, July 31, 2005 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 30, 2005, 20:02 local (Jul 31, 2005, 03:02 UTC) - Place: San Diego, CA - Coordinates: 32.82611, -116.972503 - Nearby events: https://openairdocs.org/map.md?lat=32.8261&lon=-116.9725&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report August 29, 2006 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 62108 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX05LA251 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/62108/pdf - Page: https://openairdocs.org/ntsb/LAX05LA251 ## Probable cause The pilot's failure to ensure that the landing gear was fully extended prior to landing. A contributing factor was the pilot's diverted attention. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Gear collapsed, landing - roll - terrain condition - runway - landing gear,main gear - collapsed (cause) - gear down and locked - not verified, pilot in command (cause) - diverted attention, pilot in command (contributing factor) ## Analysis The partially extended landing gear collapsed during rollout on the runway. No evidence of a mechanical malfunction was noted with the landing gear system during the pilot's flight. The pilot said that on approach he was distracted while looking for another airplane, and he did not observe whether the green gear down light was illuminated after he extended the landing gear. He increased engine power in anticipation of performing a go-around, then located the other airplane, whereupon he closed the throttle and landed. Seconds later during rollout, the airplane's landing gear collapsed. Airport management reported that the airplane was subsequently hoisted up by a crane, the landing gear was manually extended into the locked position, and the airplane was rolled off the runway. The landing gear extension system and the related gear warning horn were functionally examined after the accident with no anomalies found. ## Factual narrative On July 30, 2005, about 2002 Pacific daylight time, a Cessna 210A, N9468X, landed on runway 27R at the Gillespie Field, San Diego, California, with the landing gear partially extended. During rollout, the landing gear collapsed. The airplane was owned by a private individual, and it was substantially damaged. The commercial pilot was not injured. Visual meteorological conditions prevailed at the time of the personal flight, and no flight plan had been filed. The flight was performed under the provisions of 14 CFR Part 91, and it originated from Long Beach, California, about 1730. The pilot reported to the National Transportation Safety Board investigator that earlier during the week the landing gear had been examined. Thereafter, he flew the borrowed airplane to Long Beach. No evidence of a mechanical malfunction was noted with the landing gear system during his takeoff from Long Beach. According to the pilot, on approach to the Gillespie Field he was distracted, and he did not observe whether the green gear down light was illuminating after he extended the landing gear. When the pilot reduced the throttle during the approach, he did not hear any gear warning horn. During the landing rollout, the partially extended landing gear collapsed, and the horizontal stabilizer bent upon impacting the runway. In the pilot's completed "Aircraft Accident Report" he indicated that during his approach for landing he was advised of another airplane ahead and below his position. The pilot reported that he was unable to locate the other airplane until he was on final approach. The other airplane made a long landing on the runway, which resulted in the accident pilot adding engine power for a possible go-around. The pilot reported "at that moment" the other airplane turned off the runway, and he was cleared to land. The pilot closed the throttle, flared, and touched down on the main wheels. Shortly after that he allowed the nose wheel to touch down, and the main landing gear collapsed. The airport manager reported to the National Transportation Safety Board investigator that under her direction the accident airplane was removed from the runway. A crane hoisted the airplane up and the landing gear was extended. The airplane was rolled off the runway without further difficulty. On August 8, 2005, the Federal Aviation Administration (FAA) coordinator verbally reported to the Safety Board investigator that the airplane had been examined. The landing gear was hydraulically raised and lowered. No anomalies were noted with its operation. The landing gear warning horn system was also functionally examined, and it operated normally. ## Aircraft - Registration: [N9468X](https://openairdocs.org/aircraft/N9468X), registered now, S/N 21057768 (OpenAirDocs) - Reported make and model: Cessna 210A - Registry model: [Cessna 210A](https://openairdocs.org/model/cessna-210a) (registry code 2073408) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 21057768 - Airframe hours: 2579 - Engines: Continental IO-470E 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Richard M.

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.
