Our newer to us IA says that the Mooney factory recommends an inspection of the landing gear box (1st at 500 hours, after 1st: every 200 Hours). (Includes: Take off box, open box, check for wear, lub, close up, return to aircraft) at a cost of ten hours of labor. Our Log books do not ever show any inspections have been done even after 40 annuals for our 1975 M20C.
Has any one every had this inspection done or heard of?
Any advise please? (to do it or not to do).
Thanks all
