Helicopter

How many hours of flight for 1 hour of maintance?

I think the question is backwards...it really is how many hours of mainteneance to 1 flight hour... On a Navy/Marine CH/MH-53E the amount is roughly 40 hours to 1 as the aircraft get smallwer that time may be reduced...Ball park figure for a medium helicopter is about 5 hrs of maintenance to 1 hour of flight to 1
