What happened
The pilot initiated a takeoff attempt on a private airstrip characterized by a short length and a steep incline. The operation was conducted under no-wind conditions, which likely exacerbated the performance challenges associated with the uphill gradient. During the initial climb phase, the aircraft drifted laterally away from the centerline of the runway.
Following liftoff, the airplane collided with three aircraft that were parked near the departure path. The impact caused the airplane to strike a line of trees and subsequently turn over, resulting in a crash landing scenario.
The investigation
Investigation of the site revealed that the takeoff was performed on an uphill slope, a maneuver that is explicitly prohibited at this privately owned airstrip. The absence of wind conditions meant there was no headwind component to assist with lift generation or ground roll reduction, further complicating the ability to achieve safe climb performance from the limited runway length.
Findings
The primary factors contributing to the accident included the unauthorized nature of the uphill takeoff and the challenging terrain. The steep incline reduced the available acceleration and lift capabilities of the aircraft. Additionally, the lack of wind conditions removed a potential variable that might have aided in short-field performance. The lateral drift after liftoff suggests a loss of directional control or insufficient climb gradient to clear obstacles safely.
Safety message
Pilots must strictly adhere to airstrip operating procedures and restrictions. Unauthorized maneuvers, such as uphill takeoffs on short strips with steep gradients, significantly increase the risk of performance-related accidents. Understanding the limitations of the aircraft in relation to the specific terrain and weather conditions is critical for safe operations.
