I am sorry for your reason to post here on PPRuNe. One of our regular contributors may be able to help you further. His PPRuNe call sign is "Old Duffer".
All I can tell you was from his book that the aircraft crashed whilst overshooting (going around in today's jargon) and dived into the ground 2.5 miles south west of the airfield. The crew were both trainees, F/L Seerala H NAIDU (age 27) and F/L Dwarika P PANDAY (age 25). Both crew were sadly killed.
The aircraft was from 231 OCU based at Bassingbourn.
There is no mention of the cause or weather condition at the time. The National Record Office at Kew (London) will have a file and perhaps a copy of the accident report and investigation from the Board of Inquiry. That is your best chance of finding out more of what happened to your uncle. The same happened to my uncle in May 1956 (WT328).
I hope that this gives you more to go on. Good luck with your quest.
