October 29, 2018

McCauley has issued Alert Service Bulletin ASB273A A-20028 IDLER GOVERNOR GEAR BEARING INSPECTION dated 23 Oct 18.  It affects certain McCauley governors manufactured between 31 Jan 17 and 27 Sep 18 and ALL McCauley governors that have been overhauled or had the idler governor gear bearing replaced between 31 Jan 17 and 27 Sep 18.  McCauley has become aware of an unapproved variant of the McCauley P/N A-20028 governor gear bearing that may fail prematurely, causing governor failure and oil contamination in the engine and propeller. Early symptoms of the failure may include erratic governor behavior, including the inability of the governor to hold selected RPM, hunting, surging, etc. Please call or email LGM if there are any questions concerning this SB. Thanks.
