New Aztec Nacelles Update

Sneak-preview of the fiberglass/composite Aztec nacelles. The project is currently in the STC certification-plan approval stage. This aircraft has not been test-flown as of yet but we fully expect these nacelles to perform on the Aztec in the same manner as our previously approved nacelles perform on the 4-Cylinder Apache models.
 
This particular aircraft  is a turbo model but we also have them for the normally aspirated Aztecs. They are a 2-piece design to replace the stock 6 or 7 piece assemblies. The nacelles can be removed in 3 minutes, reinstalled in 5 minutes due to a 100% camloc attachment system and no need to remove the cowl flap section for normal servicing. They feature lower drag and improved engine cooling, along with an improved induction design. We fully expect that Aztec owners will be flying their aircraft with cowl flaps closed in cruise which alone increases cruise speeds by 5-8 MPH.
