Service Bulletin

Service Bulletins

A Service Bulletin is the equivalent of an AD on a Certified Aircraft. In the Experimental Regulations, no channel exists for AD's, as such we call them Service Bulletins. A Service Letter is either a suggested change, or designed as an assistance to the owner for an area where multiple difficulties arise.

Pricing shown in any Service Bulletin or Service Letter that is older than 90 days is not valid.
