Shortly thereafter, the engine “sputtered”, and he began to troubleshoot the engine problem “all while looking for a place to land.” He then realized the engine issue could be carburetor ice. He reached for the carburetor heat handle, and the airplane impacted a power line. The airplane impacted the water and sustained substantial damage to the left wings and fuselage. The passenger reported that the airplane was “running completely fine the entire ride, we then began flying really low [and the pilot] said, ‘this is where I like to do some water dancing.’” The pilot continued to fly low over the water around the curves of the lake, and the engine continued to operate without an issue. While flying level, the passenger noticed the airplane was about the altitude of some power lines when the airplane impacted the power lines and then the water. A nearby boat assisted with their egress from the water. Automatic Dependent Surveillance-Broadcast data was consistent with the passenger’s recollection of the flight path and circumstances. ## Aircraft - Registration: [N132JD](https://openairdocs.org/deregistered/N132JD-2023-04-17), registration cancelled 2023-04-17, S/N 75-2812, built 1941 (OpenAirDocs) - Reported make and model: BOEING A75N1(PT17) - Registry model: [Boeing A75N1(PT17)](https://openairdocs.org/model/boeing-a75n1-pt17) (registry code 1380134) (OpenAirDocs) - Registry engine: [Continental W670-6A](https://openairdocs.org/engine/continental-w670-6a) (registry code 17317, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 75-2812 - Year built: 1941 - Airframe hours: 4015 - Engines: Continental W-670-6N 220 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Unknown, June 1, 2022 - Departed: OK93, Collinsville, OK - Equipment: ADS-B ## 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. 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.
