The airplane collided with two of the deer and the engine lost power as one of the propellers struck a deer. Substantial damage was sustained to the engine mount, firewall, and right forward fuselage. The flight instructor reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation. The Federal Aviation Administration (FAA) Airport Directory information for the airport listed a warning for deer on and in the vicinity of the airport. A review of the NTSB accident database and FAA wildlife strike database did not locate other incidents of wildlife strikes at this airport. The flight instructor further reported that the accident could have been prevented if deer fencing was installed at the airport. ## Aircraft - Registration: [N92505](https://openairdocs.org/aircraft/N92505), registered now, S/N 2890211, built 1994 (OpenAirDocs) - Reported make and model: PIPER PA28 (181) - Registry model: [Piper PA-28-181](https://openairdocs.org/model/piper-pa-28-181) (registry code 7102807) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 2890211 - Year built: 1994 - Airframe hours: 12433.4 - Engines: Lycoming O-360-A4M 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Thunderbird Aviation Inc - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, November 22, 2023, 12.45 hours before - Departed: KGYL, Minneapolis, MN - Destination: Same as departure - Airport: GYL, Glencoe Muni, runway 13, 3,300 × 75 ft, asphalt - Equipment: ADS-B, Electronic primary flight display, Stall warning system ## Flight crew As NTSB recorded them.
