I heard Mooney may increase the recommended 1000 hour replacement on no back spring clutch in the landing gear motor assemblies to 2000 hours but add an inspection at 1000 hours. Does anyone have any info on this?
I'm the proud, new owner of 1963 M20C, N6578U since yesterday. The prop is of the older Hartzell "non-suffix" hub with the 100 hr recurring AD for an eddy current inspection. During the pre-purchase survey earlier this week at Advanced Aircraft Services, I had expressed interest in having the prop overhauled if I bought the airplane. AAS' neighbors at Western Aircraft Propeller alerted me to a recent Aug 27, 2012 update to Hartzell service bulletin HC-SB-61-269 "Propeller - Hub Inspection." The update is significant in that it adds an FAA-approved alternate means of compliance that effectively eliminates the eddy current inspection requirement WITHOUT a costly upgrade to the B-hub. The service bulletin is updated to include an Optional Terminating Action for the hub inspection by "modification of the propeller hub to the oil-filled configuration in accordance with Hartzell Service Letter HC-SL-61-273." According to SL 273, "Converting the propeller to an oil-filled configuration will provide a method for early detection of a possible crack in the hub. The hub cavity will be filled with oil that contains a red dye. If a crack in the hub occurs, the red dyed oil will provide a visual indication" At ~$3300, the cost of an overhaul and incorporation of SL 273 kit falls about halfway between that of a prop over haul and that of a normal prop overhaul with upgrade to the B-hub. Work on my airplane's prop overhaul and SL 273 incorporation commences next week. Page from HC-SL-61-273.pdf HC-SB-61-269.pdf
