What happened
On 3 March 2026, a Z-1RA Stummelflitzer, registration G-ZIRA, was involved in an accident during a private flight at White Waltham Airfield. The pilot had completed an initial 90-minute flight earlier that day, following a pre-flight inspection that showed no issues with fuel or mechanical systems. Following a period of refueling and preparation for a second flight, the aircraft taxied to Runway 07.
During the takeoff roll, all power checks appeared normal. However, upon reaching an altitude of approximately 200 ft, the pilot noted inadequate climb performance and a reduction in engine speed. The engine began to sound hesitant, prompting the pilot to level off and activate the auxiliary fuel pump while attempting to remain over the airfield. Shortly thereafter, the engine stuttered and ceased operation.
In an attempt to avoid obstacles, the pilot directed the aircraft toward a grass area situated between several hangars and a row of parked planes. During the approach, the aircraft failed to respond to an attempt to flare. The aircraft subsequently struck the ground with significant force, landing nose-first before cartwheeling. The pilot sustained serious injuries but managed to exit the wreckage independently.
The investigation
The investigation was based on the accident report submitted by the pilot. The aircraft, which was damaged beyond economical repair, was not subjected to a formal examination of the engine or the flight control systems. Consequently, the specific technical reasons for the engine's failure and the lack of aerodynamic response during the landing flare remain unknown.
