mechanic80 Posted August 7, 2010 Share Posted August 7, 2010 A number of RGB's have failed due to quite a handsome size of metal chunks detected by magnetic drain plugs..what could be the possible reasons for this cause... oil used is 23699 and is changed properly. Propeller dynamic balancing is also done properly. engine used is T-56-A-15 unable to find a good reason for these overhauled RGB's.:confused: Quote Link to comment Share on other sites More sharing options...
