Zalt,
Are you and PANews related? Yes I do have the inside "gen", and by the way, MDHI DOES NOT OWN THE MAINTENANCE FACILITY IN QUESTION.
Sadly you are right, seemsd all to common that the first sales of a new type are on the basis of 'on condition' maintenance and soon the ADs come in to reverse it.
I am confused with this comment. To the best of my knowledge both the blade pins and hub assemblies on this aircraft have always had time lives. This design of blade pin is not unique to the MD900 series aircraft and is time-limited on the 369 series as well as the Apache.
