During the student pilot’s first landing, he observed the left wing and main gear lift, and the student pilot overcorrected to the left and exited the runway into grass. The student pilot elected to execute a go-around, but impacted the rooftop of a hangar. The airplane sustained substantial damage to the wings and fuselage. The instructor reported there were no preaccident mechanical malfunctions or failures that would have precluded normal operation. ## Aircraft - Registration: [N3307E](https://openairdocs.org/deregistered/N3307E-2023-11-08), registration cancelled 2023-11-08, S/N 17271499 (OpenAirDocs) - Reported make and model: CESSNA 172N - Registry model: [Cessna 172N](https://openairdocs.org/model/cessna-172n) (registry code 2072434) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17271499 - Year built: 1979 - Airframe hours: 4059 - Engines: LYCOMING 0-320 SERIES 160 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Pacific Air Flight School, LLC, doing business as Flight School - Registered owner: Jeffrey & Weiss Holdings LLC - Airworthiness certificate: Standard, Normal; Standard, Utility - Last inspection: 100 hour, June 23, 2023 - Destination: Same as departure - Airport: LGB, Long Beach Airport (Daugherty Field), runway 26L, 6,192 × 150 ft, asphalt - Equipment: Electronic flight bag or handheld device, ADS-B, Stall warning system ## Flight crew As NTSB recorded them.
