Aircraft Accident Records

I am researching the service history of a Meteor NF14 – WS726 – and have discovered the aircraft was damaged in an accident on 29/5/1963, the damage being categorised as Cat 3R. It was out of service for two months being repaired on site by a party from 30 MU Dishforth

Despite contact with Air Historical Branch & Hendon who do not have any records, I have come to a dead end. I would very much like to know more about the accident can anyone suggest any ideas please, the aircraft was with No 1 Air Navigation School at the time.
