After reading the report of the Irish accident linked to, I wonder if this is a type-specific problem with fire. The Irish pilot escaped before the fire. Without fire, this would have been a slight or no injury accident. The AAIB report mentions the document discrepancies, but does not consider them as causing the accident. The pilot seems to have been injured only because he stayed to rescue his passenger. The take-off data does not show an overloaded aircraft struggling to get airborne. The pilot had plenty of hours to be familiar with the prop and performance. Loss of some power at climb out means a gamble as to whether it will continue at that power, lose more, or improve. With the terrain he faced, I doubt if any decision could be criticised
