My point wasn't about engine reliability, or a PC-12/B200 debate. A single engine aircraft will do all the same things a multi engine aircraft will do with the same equipment, no argument with that. Its an engine and they malfunction, in most cases it's as simple as an "O" ring, linkage, incorrect essembly or component.
The point I was making is that, if your flying around the territory at night, particularly in the wet season in a single engine aircraft and that engine stops, you're dead. To argue against that means you support acceptable losses, which is little comfort to the crew and medical staff who are exposed to that risk every day.
Had two of the four failures I have experienced in my career occurred in a single engine aircraft, there is no doubt I would not be here today, end of story.
