After multiple takeoffs and landings on the owner’s field, the flight instructor took off, turned prematurely, and clipped a fence with the right wing. The airplane flipped over, impacted terrain, and came to a rest inverted, which resulted in substantial damage to the forward fuselage and both wings. The flight instructor reported that there were no preimpact malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N750EE](https://openairdocs.org/aircraft/N750EE), registered now, S/N 75-8157 (OpenAirDocs) - Reported make and model: ZENITH CH-750 - Registry model: [James D Buie CH-750](https://openairdocs.org/model/james-d-buie-ch-750) (registry code 056300G) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 75-8157 - Year built: 2011 - Airframe hours: 47.1 - Engines: Jabiru 3300 120 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, April 24, 2024 - Departed: SER, Seymour, IN ## Flight crew As NTSB recorded them.
