A witness reported that the wing flaps were fully deployed during takeoff. Subsequently, the airplane clipped several trees and then its left landing gear struck a power line that resulted in a descent and impact with a building. The airplane sustained substantial damage to the wings, fuselage, and empennage. The flight instructor stated that there were no preimpact mechanical anomalies or malfunctions with the engine that would have precluded normal operation. Postaccident review of the accident site photographs revealed that the airplane’s flaps were extended rather than fully retracted as specified in the airplane’s Pilot Operating Handbook. ## Aircraft - Registration: [N8047F](https://openairdocs.org/aircraft/N8047F), registered now, S/N 15064147, built 1966 (OpenAirDocs) - Reported make and model: CESSNA 150F - Registry model: [Cessna 150F](https://openairdocs.org/model/cessna-150f) (registry code 2071814) (OpenAirDocs) - Registry engine: [Continental 0-200 series](https://openairdocs.org/engine/continental-0-200-series) (registry code 17020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15064147 - Year built: 1966 - Airframe hours: 6505.7 - Engines: CONT MOTOR O-200 SERIES 100 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, August 4, 2025 - Departed: U56, Rigby, ID - Airport: U56, Rigby Airport, runway 1, 3,727 × 50 ft, asphalt - Equipment: ADS-B, Stall warning system ## Flight crew As NTSB recorded them.
