What happened
On 19 March 2011, an X’Air 582, registration G-BZLT, was conducting a private flight near Portadown, Northern Ireland. The aircraft had been stationary in a hangar since December 2010. During the pre-flight routine, the pilot performed a power run and checked engine parameters, which appeared normal. After takeoff, the aircraft reached a cruise altitude of 1,000 ft.
Approximately eight minutes into the flight, the engine ceased operation. The pilot attempted several restarts; while the engine initially responded to throttle inputs, it failed repeatedly. After two further unsuccessful attempts, the pilot identified a large grass field ahead as the most suitable landing site. The pilot executed a shallow 180-degree turn to align with the field, descending to roughly 600 ft.
Upon touchdown, the aircraft's nosewheel sank into soft ground. This caused the aircraft to pitch forward and come to rest in an inverted position. There were no injuries to the pilot or the passenger, though the front fuselage and nosewheel sustained damage.
The investigation
Investigators examined the engine and electrical systems, finding no evidence of mechanical failure or electrical blockage. The fuel tank, which held approximately ten litres of fuel, was replenished with 20 litres prior to the flight. While the investigation noted the presence of small debris particles within the fuel tank, it was impossible to confirm if these particles entered the system during or after the accident. The pilot also noted that a water drain check of the fuel system had not been performed during the pre-flight inspection.
