What happened
On 2 January 2014, a private scenic flight departing from Nelspruit (FANS) resulted in an aircraft accident at The Rest airfield in Mpumalanga. During the flight, the pilot elected to perform a runway inspection fly-over of the private airstrip. While performing the low-level pass, the aircraft encountered a 7 kt tailwind. As the pilot attempted to climb out, the aircraft's airspeed decreased significantly. This loss of speed caused the aircraft to enter a stall at a low altitude, leading to a ground impact approximately 100 meters from the runway threshold. The pilot and passenger escaped the incident without injuries, though the Bantam B22J, registration ZU-EFZ, sustained damage to its engine, propeller, wings, and fuselage.
The investigation
SACAA AIID investigators examined the wreckage and flight circumstances to determine the sequence of events. The investigation confirmed that the aircraft was well within its maximum takeoff weight, at 395 kg against a limit of 450 kg. Maintenance records for the Bantam B22J were found to be in compliance with all regulatory requirements, and the aircraft was considered fully serviceable. Analysis of the wreckage indicated that the impact was consistent with a left-hand turn and a potential spin, with the left wing and engine being the primary points of contact with the ground. The investigation also noted that the pilot's attempt to clear rising terrain and trees beyond the runway threshold necessitated an increased angle of attack.
Findings
- The pilot was properly licensed and qualified for the operation.
- The aircraft was maintained according to approved regulatory procedures.
- The flight was conducted with a 7 kt tailwind, which necessitates higher airspeeds to maintain lift.
- The pilot failed to maintain adequate airspeed, allowing the aircraft to decay into a stall.
- Obstacles, including trees and rising terrain, distracted the pilot and prompted an excessive angle of attack, leaving insufficient altitude for stall recovery.
