Overhaul intervals and expected life times

different depending on service conditions. Expected component lifetimes have been adjusted
to match overhaul intervals.
Achieved life times very much depend on the operating conditions, average loading of the
engine, fuel quality used, fuel handling systems, performance of maintenance etc.
