A simple question for those in the know. At What service does a light piston heli require to be test flown by the maintenance organisation? 100 hour? Annual? or just C of A?
In the Robinson maintenance manual you are required to carry out a maintenance test flight with an engineer on board every 100 hrs. Perhaps you should read it. Which helicopter are you referring to?
The matter was picked up as a non compliance during a CAA audit of a maintenance organisation that I know of. It's now carried out as per the Maintenance manual.
