What happened
The pilot initiated a takeoff using soft field techniques from the threshold of the runway. During the ground roll, the pilot noticed the runway end markers positioned at the far end of the strip. In response to this observation, the pilot elected to extend the flaps to the full position while still accelerating on the ground.
The aircraft managed to become airborne just before striking the runway end markers. Following the collision with the markers, the aircraft lost control and settled into a cluster of trees located off the end of the runway.
The investigation
Post-accident research uncovered critical context regarding the state of the airfield at the time of the incident. It was determined that a Notice to Airmen (NOTAM) had been in effect for five days prior to the accident. This NOTAM, which had been initiated by the pilot himself, officially closed the runway until conditions improved.
Findings
The sequence of events indicates a disconnect between the pilot's decision to take off and the active closure of the facility. The late deployment of flaps during the takeoff roll likely compromised the aircraft's ability to clear the obstacles at the end of the runway. The presence of the NOTAM suggests that the pilot was aware, or should have been aware, that the runway was not available for use.
Safety message
Pilots must verify the current status of a runway via NOTAMs before initiating any flight operations. Operating on a closed runway poses significant risks and violates standard safety protocols.
