# NTSB ATL04LA035: Cessna 210D, N3728Y, Millington, TN, November 9, 2003 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: November 9, 2003, 14:19 local (20:19 UTC) - Place: Millington, TN - Coordinates: 35.36111, -89.872497 - Nearby events: https://openairdocs.org/map.md?lat=35.3611&lon=-89.8725&mi=10 - Phase of flight: [Emergency descent](https://openairdocs.org/ntsb-phases/600) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report June 28, 2006 - Report: Approved by Office Director - Parties: Memphis FSDO-25 - NTSB case key (mKey): 58319 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL04LA035 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/58319/pdf - Page: https://openairdocs.org/ntsb/ATL04LA035 ## Probable cause The malfunction of the main hydraulic landing gear system actuator resulting in an emergency gear up landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, emergency descent/landing - hydraulic system,actuator - malfunction (cause) - Wheels up landing, emergency landing - terrain condition - ground ## Analysis The pilot stated that he was conducting touch and go landings at an airport when he observed an unsafe landing gear indication after attempting to lower the landing gear. The emergency gear extension checklist was followed and the landing gear would not come down. He diverted to another airport and contacted the control tower. A fly-by was requested and the controller informed the pilot that the nose gear was extended, however the main landing gear was not extended. The pilot entered the traffic pattern and made an emergency landing to the sod area left of runway 04. The landing gear actuator was forwarded to an authorized repair station for further examination. The examination revealed the actuator was in the partially extended position during the gear up landing. The repair station confirmed the hydraulic pump was functioning, and the landing gear actuator was in the partially extended position during the gear up landing. The teardown concluded, "It is our professional opinion, based on non-teardown of the unit that the power pack would have functioned and sequenced as designed; however, there is serious question as to the ability of the main gear actuators to overcome the flight loads if operated at 60 percent (fluctuating between 750 psi and 900 psi) of designed system pressure (required to be at 1950 plus or minus 50 psi.") ## Factual narrative On November 9, 2003, at 1419 central standard time, a Cessna 210D, N3728Y, registered to a private owner, operating as a 14 CFR Part 91 personal flight, made an emergency landing at the Millington Municipal Airport, Millington, Tennessee. Visual meteorological conditions prevailed and no flight plan was filed. The airplane received substantial damage. The commercial pilot and commercial rated pilot passenger reported no injuries. The flight originated from Dyersburg Municipal Airport, Dyersburg, Tennessee, on November 9, 2003, at 1400. The pilot stated they were conducting touch and go landings at Dyersburg Municipal Airport and received an unsafe landing gear indication after attempting to lower the landing gear. The emergency gear extension checklist was followed and the landing gear would not come down. He diverted to Millington Municipal Airport and contacted the control tower. A fly-by was requested so the tower controller could check the status of the landing gear. The tower controller informed him that the nose gear was extended, however the main landing gear was not extended. The pilot entered the traffic pattern and made an emergency landing to the sod area left of runway 04. After touchdown the airplane slide to the right, went up on the runway, and came to a stop. Examination of the airplane revealed the right horizontal stabilizer sustained structural damage. The landing gear actuator was forward to Aircraft Parts and Accessory Exchange for further examination. The examination revealed the actuator was in the partially extended position during the gear up landing. The hydraulic pump was functioning. The teardown concluded, "It is our professional opinion, based on non-teardown of the unit that the powerpack would have functioned and sequenced as designed; however, there is serious question as to the ability of the main gear actuators to overcome the flight loads if operated at 60 percent (fluxuating between 750 psi and 900 psi) of designed system pressure (required to be at 1950 plus or minus 50 psi.)". ## Aircraft - Registration: [N3728Y](https://openairdocs.org/aircraft/N3728Y), registered now, S/N 21058228, built 1963 (OpenAirDocs) - Reported make and model: Cessna 210D - Registry model: [Cessna 210D](https://openairdocs.org/model/cessna-210d) (registry code 2073414) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 210-58228 - Airframe hours: 5132 - Engines: Continental IO-520-A29 285 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: John G.

(-23) Pilot could not get main gear to indicate down and lock. Fly-by control tower confirmed nose gear down but not main gear. Pilot used emergency procedures… 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.
