The pilot advanced the throttle and lowered the nose of the airplane to recover from the maneuver, when the right wing dropped, the airplane rolled over inverted, and subsequently entered a right spiral dive. The pilot reported that after 5 to 7 turns he regained control of the airplane leveling at 500 to 700 ft agl. The pilot returned to the airport and landed without further incident. Postaccident examination revealed the airplane sustained substantial damage to the fuselage above the left wing’s trailing edge, below and forward of the empennage, above the right horizontal stabilizer, and at the tail cone below the right and left horizontal stabilizers. The pilot reported there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N920X](https://openairdocs.org/aircraft/N920X), registered now, S/N 4692206, built 2014 (OpenAirDocs) - Reported make and model: Piper PA46R-350T - Registry model: [Piper PA46R-350T](https://openairdocs.org/model/piper-pa46r-350t) (registry code 7104610) (OpenAirDocs) - Registry engine: [Lycoming TIO-540-AE2A](https://openairdocs.org/engine/lycoming-tio-540-ae2a) (registry code 41999, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 4692206 - Year built: 2014 - Airframe hours: 815.9 - Engines: Lycoming TIO-540-AE2A 350 horsepower turbo shaft - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Coadmere INC - Registered owner: Coadmere INC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, January 30, 2020, 30 hours before - Departed: ROG, Rogers, AR - Flight plan: VFR - Airport: ROG, Rogers Executive Airport - Carter Field - Equipment: Electronic multifunction display, Electronic flight bag or handheld device, Auto-pilot, Stall warning system, Electronic primary flight display ## Flight crew As NTSB recorded them.
