 Document: SIAI Marchetti Service Bulletin 260 B35.

           Note: FAA AD 83-06-10 refers.

           Compliance:  For those governors with a relief valve body which has a rectangular port, by 31 July 1983 and every maintenance release inspection thereafter. For those governors with a relief valve body which has a round port, by 31st July 1983 and every 500 hours time in service thereafter.

             Background:  1. The manufacturer advises instances of spring P/No. A3107 breakage. Breakage of this spring can cause lowering of governor oil pressure and a harmful "overspeed" of the propeller.

             2. This AD has been reprinted to correct a typographical error under applicability for Hartzell FA-112, SIAI equivalent should read 260-13-272-03.
