The left wing of the Remos collided with the propeller of the other airplane, resulting in substantial damage to the left wing and aileron. The Cessna sustained minor damage to the propeller. The pilots of both airplanes reported that there were no preaccident mechanical malfunctions and failures with the airplanes that would have precluded normal operation. ## Aircraft 1 - Registration: [N126GX](https://openairdocs.org/aircraft/N126GX), registered now, S/N 342, built 2009 (OpenAirDocs) - Reported make and model: REMOS GX - Registry model: [Remos Acft Gmbh Flugzeugbau REMOS GX](https://openairdocs.org/model/remos-acft-gmbh-flugzeugbau-remos-gx) (registry code 060006H) (OpenAirDocs) - Registry engine: [Rotax 912ULS series](https://openairdocs.org/engine/rotax-912uls-series) (registry code 55572, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 342 - Year built: 2009 - Airframe hours: 2690.6 - Engines: ROTAX 912ULS 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Eagle Sport LLC, doing business as Fly Eagle Sport - Registered owner: Culprit Aviation LLC - Airworthiness certificate: Special, Special light-sport (Special) - Last inspection: 100 hour, October 2, 2024, 77.8 hours before - Destination: KGEU, Glendale, AZ - Airport: PRC, Prescott Rgnl/Ernest A Love Fld - Equipment: Electronic flight bag or handheld device, Auto-pilot, ADS-B, Electronic primary flight display, Electronic multifunction display ## Aircraft 2 - Registration: [N516ER](https://openairdocs.org/aircraft/N516ER), registered now, S/N 172S12867, built 2022 (OpenAirDocs) - Reported make and model: CESSNA 172 (S) - Registry model: [Textron 172S](https://openairdocs.org/model/textron-172s) (registry code 2072449) (OpenAirDocs) - Registry engine: [Lycoming IO-360-L2A](https://openairdocs.org/engine/lycoming-io-360-l2a) (registry code 41597, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 172S12867 - Year built: 2022 - Airframe hours: 1920 - Engines: LYCOMING IO-360-L2A 180 horsepower reciprocating - Damage: Minor damage - Flight: Instructional, Part 91 - Operator: Embry Riddle Aeronautical University Inc, doing business as Embry Riddle Aeronautical University - Registered owner: Embry Riddle Aeronautical University Inc - Airworthiness certificate: Standard, Normal - Last inspection: Continuous airworthiness, November 12, 2024, 21 hours before - Equipment: Electronic multifunction display, Electronic flight bag or handheld device, Electronic primary flight display, Auto-pilot, ADS-B ## Flight crew As NTSB recorded them.
