Report Says Kill Switch Fail Caused Racing Drone Crash
The UK Air Accidents Investigation Branch (AAIB) has just released a report into the crash of a racing drone that was
being used for a demonstration flight at Goodwood Aerodrome in July 2019.
Whilst performing a demonstration flight, the
remote pilot lost control of the 95 kg Alauda Airspeeder Mk II scale
demonstrator. After the loss of control had been confirmed by the remote pilot,
the safety ‘kill switch’ was operated but had no effect. The Unmanned Aircraft
then climbed to approximately 8,000 ft, entering controlled airspace at a
holding point for flights arriving at Gatwick Airport, before its battery
depleted and it fell to the ground. It crashed in a field of crops approximately
40 m from occupied houses and 700 m outside of its designated operating area.
There were no injuries.
The AAIB found that the Alauda Airspeeder Mk II was not designed, built or tested to any
recognisable standards and that its design and build quality were of a poor
standard. The operator’s Operating Safety Case contained several statements
that were shown to be untrue.
Alauda
Airspeeder Mk II
The Civil Aviation Authority’s Unmanned Aircraft
Systems (UAS) Unit had assessed the operator’s application and, after
clarification and amendment of some aspects, issued an exemption to the Air
Navigation Order to allow flights in accordance with the operator’s Operating
Safety Case. The Civil Aviation Authority did not meet the operator or inspect
the Alauda Airspeeder Mk II before the accident flight.
The Civil Aviation Authority and the organisation
which designed and operated the Airspeeder Mk II have introduced measures to
address a number of issues identified during the course of the investigation.
In addition to the actions already taken this investigation report makes 15
Safety Recommendations regarding the operator’s procedures, airworthiness
standards and the regulatory oversight.
