# NTSB FTW01LA170: Cessna T210N, N6114A, Amarillo, TX, July 21, 2001 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 21, 2001, 12:15 local (17:15 UTC) - Place: Amarillo, TX - Coordinates: 35.219596, -101.709053 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=35.2196&lon=-101.7091&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report May 21, 2002 - Report: Approved by Office Director - Parties: FAA FSDO - NTSB case key (mKey): 52807 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW01LA170 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/52807/pdf - Page: https://openairdocs.org/ntsb/FTW01LA170 ## Probable cause the pilot's failure to verify that the landing gear was extended and locked before landing. A contributing factor was a tripped landing gear motor circuit breaker, which resulted in the failure of the main landing gear to fully extend and lock. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Gear collapsed, landing - flare/touchdown - electrical system,circuit breaker - popped/tripped (contributing factor) - gear down and locked - not verified, pilot in command (cause) - landing gear,main gear - unlocked (contributing factor) ## Analysis The pilot put the landing gear control switch to the down position when he was 5 miles from landing. Prior to turning final, he "verified" that the gear was extended by looking out the window and into the mirror under the right wing. As the airplane was touching down on the runway, the gear warning horn sounded. After touchdown, the main landing gear collapsed, and the nose landing gear remained extended. The airplane tilted to the left, the left wing struck the runway, and the airplane turned 90 degrees and exited the runway. An examination of the cockpit by an FAA inspector revealed a tripped/popped landing gear motor circuit breaker. The circuit breaker was reset, and the gear was successfully pumped down by hand using the emergency gear extension mechanism. ## Factual narrative On July 21, 2001, at 1215 central daylight time, a Cessna T210N single-engine airplane, N6114A, was substantially damaged during landing at the Amarillo International Airport near Amarillo, Texas. The airplane was registered to and operated by the pilot. The private pilot, sole occupant of the airplane, was not injured. Visual meteorological conditions prevailed, and no flight plan was filed for the 14 Code of Federal Regulations Part 91 personal flight. The flight originated from Sugar Land, Texas, at 0900. According to the pilot, he put the landing gear control switch to the down position when he was 5 miles from landing. Prior to turning final, he "verified" that the gear was extended by looking out the window and into the mirror under the right wing. As the airplane was touching down on runway 22, the gear warning horn sounded. After touchdown, the main landing gear collapsed, and the nose landing gear remained extended. When the "wings lost lift," the airplane tilted to the left, the left wing struck the runway, and the airplane turned 90 degrees and exited the runway. The pilot stated in the Recommendation (How could this accident have been prevented) section of the Pilot/Operator Aircraft Accident Report, NTSB Form 6120.1/2, that the accident could have been prevented by better training for the pilot on the failure of the gear to extend and lock, and practice of manual gear extension. An examination of the airplane by the FAA inspector, who responded to the accident site, revealed that the left wing tip, left horizontal stabilizer and left elevator were damaged. A subsequent examination of the cockpit revealed "a tripped [landing] gear motor circuit breaker." The circuit breaker was reset, and the gear was successfully pumped down by hand using the emergency gear extension mechanism. ## Aircraft - Registration: [N6114A](https://openairdocs.org/deregistered/N6114A-2018-05-03), registration cancelled 2018-05-03, S/N 21063499, built 1979 (OpenAirDocs) - Reported make and model: Cessna T210N - Registry model: [Cessna T210N](https://openairdocs.org/model/cessna-t210n) (registry code 2073456) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 21063489 - Airframe hours: 1240 - Engines: Continental TSIO-520-r 310 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: James D.

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.
