SERVICE BULLETINS

SERVICE BULLETINS

The latest service bulletins will be posted on this page. Please return often to maintain your aircraft in the best possible fashion!

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.
