There is a report at The National Archives, Kew:

I have an 'S' report for the crash of XD-864 which came as part of an 'RAF Court of Inquiry into an Aircraft Accident' for that aircraft which was at Kew as BT233/439. This latter document was around 100 pages plus with about twenty photos of the crash site. The 'S' report is three pages. I've no idea if a full Court of Inquiry exists for XA-929 (if you use the 'search' on the National Archive page, no report comes up for XA929 or XA-929 - it does for XD864).
The RAF Museum, Hendon, have Crash Cards, literally a card with the basic details of the crash.
To give you an idea of what these look like, here is the Court of Inquiry for XD-864:

On page 93 is the 'S' report, and page 110 the crash card.
