[Davidnane]

Hi, 

 

I want to know that for  Rotax engine service bullition SB-914-039 that required  clarification that who can give authorization

 

for increased of TBO from 12 years to 15 years?

I don't think anyone "gives" authorization. If you have complied with the requirements of the SB - and those other SB's it references - your TBO becomes what is written in the SB in hours or years.
