SS, yes SSLs on the Sea King but ECLs on the Lynx - it took me a couple of years to switch over from PTIT to T6 and then the same back again.
Yes, that is the incident which highlighted the shortcomings in the FRC drills - see my previous post about engine oil pressure failures in the Lynx. If you don't assume the worst and retard the the ECL, the engine is very likely (as in this sad case) to blow up as the reduction gearbox seizes and the FPT shears. Investigation into most precautionary engine shutdowns on the Lynx reveals a full complement of oil but a clogging filter.
