For the homebuilder; is that 1000 hours of flying experience, or 1000 hours
of maintenance experience, or perhaps 1000 hours of experience in
manufacturing and assembling rotorcraft?

It is said that the Sikorsky Sea King requires 7-12 hours of maintenance for
every hour of flying.

Maybe the maintained experience is the most important.for safe flight????
Just a question.
