Many years ago at Essendon, a Victorian Aerial Ambulance Cessna 402 lost an engine shortly after lift off. It had difficulty maintaining height and about a minute after take off it reached Vmca and flicked and spun in killing all aboard. The failed engine propeller was not feathered before impact which is probably why the climb performance was limited. The policy of the company (the chief pilot was in the accident aircraft) was all instrument rating tests and recurrent training involving simulated engine failures were conducted in the company Cessna 310. The chief pilot did not want to use the Cessna 402 because in his opinion the 402 engines needed lots of careful engine handling whereas those of the Cessna 310 were more robust. It was a cost thing.
It would instructive to know if company recurrency training in the Mojave involved asymmetric flight or if another type was used for this purpose.
