There are two photos of TG616 in Keith Wilson's RAF in Camera - 1950s, though the captions seem to contradict each other. The first:

"Handley Page Hastings Met.1, TG616, photographed in April 1951, shortly after conversion by the manufacturer to its weather reconnaissance role. After joining 511 Squadron as a standard transport aircraft in January 1950, TG616 was returned to Handley Page for conversion in November. Following the completion of the work, the aircraft was transferred to 5 Maintenance Unit in April 1951 and remained in store until returned to C.1 standard in late 1954 to fly with 53/99 Squadron at RAF Lyneham. Further service with Nos 114 and 36 Squadrons at nearby RAF Colerne followed, until the aircraft was transferred to training duties with 242 Operational Conversion Unit at RAF Dishforth in September 1961. In 1967, TG616 was withdrawn from use and moved to RAF Marham for firefighting practice."

The second:

"A Hastings Met.1 aircraft (TG616) heads out over the Atlantic on a weather reconnaissance sortie on 9 August 1954. The information radioed back to base was flashed to the Central Forecasting Office at Dunstable and formed the basis of daily weather reports. TG616 was one of a number of Hastings C.1 aircraft converted for this special role. Most, including TG616, were later reverted back to C.1 status. The aircraft served with No 202 Squadron of Coastal Command, based at RAF Aldergrove, from 1953 until the unit was disbanded on 31 July 1964."

No mention of an accident, but if the first caption is correct it may have been at RAF Marham while being used for firefighting.
