Factors were the unsecured landing gear door, the nose landing gear becoming jammed and the gear extension not possible by the pilot. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, takeoff - initial climb - door,landing gear - not secured (contributing factor) - maintenance,installation - not performed, other maintenance personnel (cause) - On ground/water encounter with terrain/water, landing - flare/touchdown - landing gear,nose gear - jammed (contributing factor) - gear extension - not possible, pilot in command (contributing factor) ## Analysis The airplane landed with the nose landing gear not extended. Examination of the airplane revealed that the linkage for the right nose landing gear door was not secured. When the landing gear was retracted on the previous departure, the nose landing gear became trapped and inoperable. The accident flight was the first flight after the airplane had been painted. The nose landing gear doors were disengaged during that maintenance. ## Factual narrative On June 19, 1998, at 1908 central daylight time, a Cessna 310N, N5030Q, received substantial damage when landing on runway 36 (5,000' x 75' dry/asphalt), near Janesville, Wisconsin, with the nose landing gear not extended. The pilot said that the airplane had just been painted and the nose landing gear door was not properly attached after painting. On retraction of the nose landing gear the nosewheel became trapped by the door and could not be extended again. The pilot reported no injuries. The 14 CFR Part 91 flight was operating in visual meteorological conditions. No flight plan was on file. The flight departed Watertown, Wisconsin, at 1810. Examination of the airplane after the accident revealed that the linkage for the right nose landing gear door was not secured. When the landing gear was retracted on the previous departure, the nose landing gear became trapped and inoperable. Repeated attempts to extend the nose landing gear were unsuccessful and the airplane landed with the nose landing gear not extended. The accident flight was the first flight after the airplane had been painted. The nose landing gear doors were disengaged during that maintenance. ## Aircraft - Registration: [N5030Q](https://openairdocs.org/deregistered/N5030Q-2008-04-02), registration cancelled 2008-04-02, S/N 310N-0130, built 1968 (OpenAirDocs) - Reported make and model: Cessna 310N - Registry model: [Cessna 310N](https://openairdocs.org/model/cessna-310n) (registry code 2074234) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 310N-0130 - Engines: Continental IO-470-V 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Viking Transport Ltd - Airworthiness certificate: Standard, Normal - Departed: RYV, WATERTOWN, WI - Destination: JVL - Airport: JVL, Rock County, runway 36, 5,000 × 75 ft, asphalt ## Flight crew As NTSB recorded them.
