With regard to the Sapphire engine, I recollect being told by a 29Sqn Engine Fitter at Leuchars that it was prone to a phenomenon called "centre-line closure"- I think that was the term. Would anyone have any idea what this would be, and how it was overcome, if at all?
The Avpin starter used to scare the tripes out of me, however ready I was for it, just like the PR9 Canberra of 13Sqn. I also remember the propensity for the #1 Royal Inverter(?) being the cause of start-up fires, not sure how.
Kind regards,
