Narrative:

I was assigned a sikorsky sk-61N helicopter for a passenger/cargo flight. I checked the logbook and noticed that four days earlier; maintenance had replaced a control rod on the stator vanes. I asked maintenance if an engine topping check (etc) had been completed on the functional check flight; they informed me none was required. [Approximately seven days later]; our company check airmen was assigned the same helicopter and he asked the same question; the mechanic said 'yes;' a topping check was required. The pilots and mechanics got together and our quality control (qc) became involved. After researching in the manuals; we came to the conclusion that; yes; a topping check was required. We need to have better communications between the flight crew and maintenance. Also; our mechanics need to have better training on 'when' and 'what' is required on a functional check flight.
