A friend of mine who lives near Ilminster is researching the crash of RAF Liberator Mk VIII KH126 on 22/11/45. It was carrying 22 members of the Royal Signals Corps from RAF Merryfield to Castel Benito in Libya.Shortly after take-off, the aircraft struck high ground in conditions of near-zero visibility. There were no survivors

The Accident Branch Investigator's Report ref W2296 contains the following item:-

"42. R. D. A.’s Defects:
Noted."

Can anyone tell me what the initials R.D.A stand for?

Many thanks in advance,
