This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 1 related events involving the same aircraft type or operator are linked below.
A student pilot flying an unauthorized cross-country training flight entered a narrow box canyon, stalled while attempting to turn, and crashed into trees below the ridge.
What happened
A student pilot was conducting a cross-country training flight that deviated from the planned route. The aircraft entered a narrow box canyon where the width was insufficient to complete a standard turn. As the pilot attempted to maneuver within the confined space, the airplane stalled and subsequently struck trees. The wreckage came to rest on the terrain approximately 300 feet below the canyon ridge.
The investigation
The investigation focused on the flight path and the physical constraints of the canyon. It was determined that the box canyon was too narrow for the aircraft to execute a safe turn. The pilot's attempt to climb and clear the terrain at the end of the canyon was unsuccessful due to the stall condition.
Findings
The primary factor contributing to the accident was the pilot's decision to enter a confined space unsuitable for the aircraft's performance capabilities. The stall occurred during the attempted turn, leading directly to the collision with the trees and the subsequent fall from the ridge.
Probable cause
The student pilot's failure to maintain adequate airspeed while maneuvering in a narrow box canyon, resulting in a stall and loss of control.
