Trinity Aviation is pleased to announce we have received our Transport Canada STC No. SH18-5 and FAA STC No. SR04156NY for our Advanced Carbon Fiber Bell Medium Vertical Tail Rotor Driveshaft Cover. This new cover is approximately 25% lighter than the original Bell cover which due to the location, translates on removal of approximately 7 additional pounds of ballast in the nose.

This STC includes a new designed hinge pin locking system that eliminates pin wear on the vertical fin and cover assembly:

The new Carbon Fiber Cover Assembly is manufactured without the use of honeycomb which eliminates debonding and corrosion damage.
