Its reliability was quite good after we learnt the lessons from G-ATCA's crash at Swansea Airport (9 Sept 1972) except for a onerous check every seven days.
David thanks for this. I was unable to discover anything substantive about ATCA's demise, in fact all I could source was this brief note in Flight International:
Flight International 14th September 1972
What exactly happened please? They were conducting low-level hover trials .. and it burst into flames!!!
