An investigation has been launched into the fatal crash on 16 May of a Diamond DA62 in Dubai.

The piston-twin, owned and operated by UK firm Flight Calibration Services (FCSL), was evaluating the navigation aids at Dubai International airport (DXB) when it crashed at 19:30 local time, 3nm (5km) from the hub, after what the Dubai government calls a "technical malfunction".

All four occupants of the aircraft were killed in the accident.

Shoreham-based FCSL specialises in inspecting and calibrating ground-based navigation aids – including instrument landing systems and primary and secondary radars – for airports and airfield owners across the world.

FCSL has not responded to a request for comment but the company website shows the contract with DXB was awarded in November 2018. Its aircraft line-up consists of five DA62s and a pair of Piper Chieftain piston-twins, which FCSL describes as the "largest fleet of flight calibration aircraft in private ownership".

Diamond Aircraft says it is "deeply saddened" by the crash and "will fully support investigations to discover as soon as possible the cause of the accident".
