Accident Investigation into the Alauda Airspeeder UAV

"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."

"All the [flight control system] assemblies failed an evaluation against all IPC A-610 classes due to quality and workmanship issues. Examples included misaligned components, burnt insulation, the use of solder bridges, excessive flux residues and a power connector that appeared to be installed in the incorrect orientation..."

"During the course of the investigation the operator demonstrated little knowledge or understanding of appropriate industry standards, in particular, those relating to airworthiness and for developing electronic hardware and software."
