I`m on my 6th 2 stroke engine: 2, Rotax 503 and 4, Rotax 582 grey head: I`ve had enough partial and total engine failures, for various reasons, to know what it`s all about, some solo, some with a student on board, walked away every time without breaking the aircraft or being injured.
My current engine is a Rotax 503 DCDI that hasn`t missed a beat, however, I treat each and every flight as a new one and accept that just because the engine didn`t fail on the last flight, doesn`t mean it won`t fail on the next flight, I`m ready to deal with an failure from the moment I apply the throttle and I will only fly over tiger country if I can safely glide clear to a suitable landing area, I have always flown this way and will continue to do so.
Each situation has it`s own scenario and there`s no magic solution to engine failure, it isn`t just limited to 2 strokes, there`s been numerous failures of 4 strokes`and for various reasons, it`s difficult to give advice to the less experienced, their instructor should have done that and there`s a vast difference between landing safely in a Drifter, or any other AC which has a tail wheel and say, the latest LSA, low wing, with a tricycle undercarriage, but basically, having a suitable landing area and the skill required to fly the aircraft safely to a full stop, is the critical part of surviving an engine failure.
Always be prepared for engine failure and regularly practice for it.
Frank.
