# NTSB ATL00IA035: Cessna CE-560, N314QS, Key Largo, FL, March 5, 2000 - Type: NTSB incident investigation - Classification: Incident · No injuries · Incident investigation · Final report - Date: March 5, 2000, 12:00 local (17:00 UTC) - Place: Key Largo, FL - Coordinates: 25.080842, -80.44033 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=25.0808&lon=-80.4403&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report December 4, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 48742 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL00IA035 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/48742/pdf - Page: https://openairdocs.org/ntsb/ATL00IA035 ## Probable cause The malfunction of the nose gear locking mechanism for undetermined reason. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, landing - flare/touchdown - landing gear,gear locking mechanism - malfunction (cause) - reason for occurrence undetermined (cause) ## Analysis The pilot completed the before landing check, which included the lowering of the landing gear, several miles on short final. The pilot recalled that the landing gear indicator lights were green, or landing gear down and locked. After the airplane landed, the pilot deployed the thrust reverses. At approximately the same time, the nose gear retracted into the wheel well. The airplane slid down runway 04, and came to rest 2000 feet from the end of the runway. The initial examination of the airplane disclosed that the nose gear up-down-lock actuator experienced a mechanical failure. During the subsequent examination of the assembly, no mechanical problem was detected during functional testing. All functional pressures and other operational parameters tested within the normal certificated limits. ## Factual narrative On March 5, 2000, at 1200 eastern standard time, a Cessna CE-560, N314QS, nose gear collapsed during a normal landing at the Ocean Reef Club Airport in Key Largo, Florida, The on demand air taxi positioning flight was operated by Executive Jet Incorporated under the provisions of Title 14 CFR Part 91 with a flight plan filed. Visual weather conditions prevailed at the time of the incident. The airplane sustained minor damage, and the two air transport pilots were not injured. The positioning flight departed Palm Beach, Florida, at approximately 1130. According to the pilot, the before landing check, which included the lowering of the landing gear, was completed several miles on short final. The pilot recalled that the landing gear indicator lights were green or indicated that the landing gear was down and locked. After the airplane landed, the pilot deployed the thrust reverses. At approximately the same time, the nose gear retracted into the wheel well. The airplane slid down runway 04, and came to rest 2000 feet from the end of the runway. The preliminary examination of the airplane disclosed that the nose gear up-down-lock actuator assembly experienced a mechanical failure. During the subsequent examination of the assembly no mechanical problem was detected during functional testing. All functional pressures and other operational parameters tested within the normal certificated limits. ## Aircraft - Registration: N314QS (not matched to a registry record) - Reported make and model: Cessna CE-560 - Category: Airplane - Serial number: 560-0441 - Airframe hours: 2619 - Engines: P&W JT15-5D 3045 lbs thrust turbo fan - Damage: Minor damage - Flight: Other work use, Part 91 - Registered owner: Executive Jet Inc. - Airworthiness certificate: Standard, Transport - Departed: PBI, PALM BEACH, FL - Destination: X09 - Flight plan: IFR - Airport: X09, Ocean Reef Club Airport, runway 4, 4,456 × 70 ft, asphalt ## Flight crew As NTSB recorded them.

Upon landing on runway 04 at the Ocean Reef Club Airport (X09) the nose gear collapsed. There were no indications of a hard landig and the aircraft received… 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
