Hi, June. there is nothing in the
Acklington Station record book for this loss. I assume this means the aircraft was from another station or with a squadron not at Acklington?
Anyway, what you are looking for is form 765. I've transcribed a few of these, here's one for Acklington,
Spitfire crash landing due to engine failure. Another with a Martinet
being taken through a hedge due to pilot error.
At the top of the form is a list of where copies of the report could end up. I would start with the Squadron or station records, at the National Archives at Kew. Although I assume all of the recipient list records are now at Kew as well.
