A post impact fire occurred. The personal flight was operating under 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed at the time of the accident. No flight plan was on file. The pilot sustained serious injuries and was hospitalized. The local flight originated at time unknown. A witness stated: When I came out of the hanger I saw the plane coming down with the wings horizontal to the ground with the left wing pointing down. The left wing hit the ground first forcing the plane to nose dive, when the front end hit the ground the plane flattened out and landed on its bottom, then slid about 100 ft and started on fire. A St. Clair County Sheriff's Deputy interviewed the pilot after the accident. The record of interview, in part, stated: In speaking with him briefly, [the pilot] was only able to say that he was involved in an accident while landing. When asked if there was some sort of equipment malfunction or if he knew what the cause of the accident was, he stated it was not an equipment malfunction, that he has had a new propeller installed and has a lower pitch, therefore he had to up the RPM'S for the landing and at that point lost control and hit the ground and rolled. He was unable to provide anymore information reference the crash besides that information. ## Aircraft - Registration: [N165WM](https://openairdocs.org/deregistered/N165WM-2008-02-21), registration cancelled 2008-02-21, S/N 165, built 1984 (OpenAirDocs) - Reported make and model: McClintock Glasair SH-2 - Registry model: [Mcclintock Willie N GLASAIR SH-2](https://openairdocs.org/model/mcclintock-willie-n-glasair-sh-2) (registry code 05655LH) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 165 - Engines: unknown - Damage: Destroyed - Fire: On-Ground - Flight: Personal, Part 91 - Registered owner: Robert W.
