I am the owner and pilot of the aircraft involved in this incident. A Mayday was declared on the Newquay Approach frequency and subsequently cancelled (via relay with another aircraft) once I'd landed.
Yes, there did seem to be a large response by the emergency services, maybe disproportionate to the size of the aircraft, but that wasn't a matter over which I had much control. I managed to speak to as many of them as possible whilst in attendance, giving them my thanks for turning out so promptly. They were all true professionals and only too pleased that their services were not required. Once again I offer my heartfelt thanks to all who were involved.
In my professional capacity as a TRE/TRI and CRMI I urge my peers to always consider the unexpected 'what ifs?' and appear to have inadvertantly created another case study for a CRM recurrent on Monday! The reason for the crankshaft failure has yet to be established and no doubt the AAIB and LAA will comment in due course.
