This accident list is the result of many years work, noting accidents reported in various sources. The accidents may be anything from a forced-landing to a total write off. I make no claims as to the accuracy of any item, but these notes may help if you wish to follow up any report. Any additions or corrections to this list would be welcome. You an email me at vicsmith@argonet.co.uk (or just click on this link)
A "?" in any column indicates that there is a definite doubt in my mind
Military serials are given in the Registration column where known, otherwise the nationality is followed by "-mil". A serial with no prefix indicates a RAF aircraft
The Type is as reported
The Location may be some distance from the accident site, particularly in more remote parts of the world. The country is assumed to be that of the registration, unless otherwise shown. Country names are those that existed at the time, e.g., Karachi would be in India, not Pakistan. Some place names are shortened, indicated by "/" to save space. All storm damage is generally described as "gale"
The Notes column gives alternate dates where sources differ, occasionally Squadron numbers, company, aircraft or pilot's names if I feel that this may be useful
