Appraiser Alastair Fallon

With a tuned knowledge and skill at providing an independent opinion of aircraft asset fair market value, Alastair Fallon is an Accredited Senior Appraiser (ASA) in the Machinery & Technical Specialties discipline, specialising in aircraft. Since 2015, he has focused on commercial helicopter appraisal, building on his prior life experience in the field of aviation.


A member of the Royal Air Force as an undergraduate studying Aeronautical Engineering and flying with the university air squadron, Alastair continued military training after completing his BEng degree (1st Class). Afterwards, he moved on to lecturing and course directorship of Air-Transport Operations.


Combining this aviation experience with finance work in a high street bank and a spell with the National Audit Office, UK, Alastair has become an expert in both aviation and financial appraisal. Having gathered enough grounding into asset appraisal, he now focuses on the aviation asset class of commercial helicopters as part of F4.
