Engine failure 'may have caused' Chester plane crash
A light aircraft crash near Chester which killed two men last year may have been caused by engine failure, air accident investigators have said.
Karl Hendrickson, 43, of Mold in Flintshire, and John Green, 50, from Surrey, died when their plane crashed on 16 August.
The Piper PA-38-112 Tomahawk came down on farmland, south of Chester.
The Air Accidents Investigation Bureau said there was no evidence to suggest pilot incapacitation caused the crash.
The AAIB report said there was no evidence a fault with the aircraft caused the crash but added: "An engine failure prior to the loss of control of the aircraft could not be ruled out."
The plane from Flintshire Flying School was reported missing by staff at Hawarden Airport in Flintshire, north Wales.
"The aircraft struck the ground while in a spin. There was no evidence to suggest pilot incapacitation or a fault with the aircraft as being causal to the accident but an engine failure prior to the loss of control of the aircraft could not be ruled out," said the AAIB report.
It added: "Although it was not possible to determine why the aircraft entered a spin, the radar data indicates that this happened when the aircraft was at a height from which recovery was unlikely to be successful."
Mr Hendrickson worked as design engineer on the single-aisle programme at Airbus in Broughton. Mr Green was a flying instructor, who had more than 10,000 hours flying experience, with the Flintshire Flying School, based at Hawarden Airport.
