# NTSB CHI99LA299: Cessna 150G, N4061J, Lambertville, MI, August 16, 1999 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: August 16, 1999, 13:45 local (17:45 UTC) - Place: Lambertville, MI - Coordinates: 41.739597, -83.620231 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=41.7396&lon=-83.6202&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report October 13, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 47086 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI99LA299 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/47086/pdf - Page: https://openairdocs.org/ntsb/CHI99LA299 ## Probable cause the inadequate aircraft preflight by the pilot and the pilot's failure to remove the aileron gust lock before flight. Factors to the accident were the soft terrain adjacent to the runway and the collapse of the nose gear. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - in flight, landing - flight control,gust lock - not removed (cause) - aircraft preflight - inadequate, pilot in command (cause) - precautionary landing - performed, pilot in command - Gear collapsed, landing - roll - terrain condition - soft (contributing factor) - landing gear,nose gear - collapsed (contributing factor) - Nose over, landing ## Analysis The airplane nosed over during a precautionary landing to runway 27. In his written statement, the pilot said that he failed to remove the aileron gust lock that was installed between the right aileron and flap. The pilot stated that he noticed that the gust lock was still installed when he made his first left turn after takeoff. The pilot said that he was able to make shallow turns and that on final approach, he, '...thru habit...', started to extend the flaps at which time the aircraft '... veered left in spite of reversing the flaps.' The pilot stated that he then was able to level the wings of the airplane but the '...nose wheel sank in the soft ground and the plane went over on its back.' The pilot did not report any preexisting mechanical discrepancies with respect to the accident airplane. The airplane came to rest in the soft farm field adjacent to the runway. A postaccident examination of the aircraft revealed no anomalies that could be associated with a preexisting condition. ## Factual narrative On August 16, 1999, at 1345 eastern daylight time, a Cessna 150G, N4061J, owned and piloted by a commercial pilot, sustained substantial damage during a precautionary landing to runway 27 (5,013 feet by 50 feet, dry asphalt) at the Toledo Suburban Airport, Lambertville, Michigan. The flight was operated under the provisions of 14 CFR Part 91 and was not on a flight plan. The pilot, who was the sole occupant, reported minor injuries. The personal flight originated at 1340 and was en route to the Ranchport Airport, Stony Ridge, Ohio. In his written statement, the pilot said that he failed to remove the aileron gust lock that was installed on the right aileron. The pilot stated that he noticed that the gust lock was still installed when he made his first left turn after takeoff. The pilot said that he was able to make shallow turns and that on final approach, he, "...thru habit...", started to extend the flaps at which time the aircraft "... veered left in spite of reversing the flaps." The pilot stated that he then was able to level the wings of the airplane, but the "...nose wheel sank in the soft ground and the plane went over on its back." The pilot did not report any preexisting mechanical discrepancies with respect to the accident airplane. The airplane came to rest in the soft farm field adjacent to runway 27. A postaccident examination of the aircraft revealed no anomalies that could be associated with a preexisting condition. ## Aircraft - Registration: [N4061J](https://openairdocs.org/aircraft/N4061J), registered now, S/N 15065361 (OpenAirDocs) - Reported make and model: Cessna 150G - Registry model: [Cessna 150G](https://openairdocs.org/model/cessna-150g) (registry code 2071816) (OpenAirDocs) - Registry engine: [Continental 0-200 series](https://openairdocs.org/engine/continental-0-200-series) (registry code 17020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15065361 - Airframe hours: 2945 - Engines: Continental O-200 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Carl B Baldwin - Airworthiness certificate: Standard, Normal - Last inspection: Annual, August 21, 1998, 26 hours before - Departed: 5G9 - Destination: 68OH, STONY RIDGE, OH - Airport: 5G9, Toledo Suburban Airport, runway 27, 5,013 × 50 ft, asphalt ## Flight crew As NTSB recorded them.

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.
