R22 A029-1 tail Blade life limitation

[Frigate AV]

The tail rotor blades, part number A029-1, on my 1993 R22 have a life time limit of 5525 hrs, with no calendar expiration, per logbook. This is also confirmed in the service manuals, that is until recent service are now printing this rotor blade with a 2200 hrs time limit, and a calendar limit of 12 years. 

So the question is, do I need to change the rotor blades, which would require also a new rotor gear box as well on the basis of a service manual, when no AD for replacement or change in service time limits has been issue?
