Accident Overview

The accident involved the Cessna U206G Stationair, registration G-CCSN, which experienced an engine failure during a downwind approach for landing. The pilot attempted to troubleshoot the issue but was unable to rectify it before executing a glide landing, which resulted in a hard landing and significant damage to the aircraft.

Pilot's Actions

Upon experiencing engine failure, the pilot checked the engine controls, including magneto switches and fuel selector, but found no issues. He proceeded with a glide approach, adjusting flaps and aligning with the runway, but ultimately landed short, leading to damage.

Post-Accident Investigation

After the accident, the operator checked the fuel levels, estimating them to be between ½ to ¾ full. Fuel samples were taken, and the engine was restarted successfully after recovery, indicating no immediate mechanical failure.

Safety notes

  • Ensure thorough pre-flight checks of fuel and engine systems to prevent similar incidents.
  • Pilots should be familiar with emergency procedures for engine failure during approach.

The pilot checked the engine controls, including the magneto switches and fuel selector, but saw nothing amiss. He continued with a glide approach, selected flaps back to up and turned onto the runway heading. Unfortunately, he was unable to reach the airfield and landed heavily in the field before it, detaching the nose landing gear and breaking the rear fuselage. One passenger sustained a minor injury. The operator of G-CCSN witnessed the accident and quickly attended the scene. In the presence of another witness, he removed the fuel caps and dipped his fingers in to verify the presence of fuel, estimating that both tanks were about ½ to ¾ full. He then took fuel samples and checked for obvious anomalies, finding none. He checked for the presence of fuel in the injection system and found a normal amount, so he decided to run the engine. After recovery, the damaged propeller blades were cropped, the battery reconnected and the engine started, running quite smoothly, despite the lack of propeller blades. At the time of preparation of this Bulletin, there is no obvious reason for the engine failure.
