 AUXILIARY STRUCTURE - DESCRIPTION AND OPERATION
_______________________________________________
 1.  General_______
 A.  Auxiliary strut/pylon structure consists of the forward fairing, upper strut to wing fairing, lower strut to wing fairing, and nacelle strut access panels some of which serve as pressure relief doors.
 2.  Access Panels_____________
 A.  Access panels are located at various places on the strut for access to tubing, ducts and electrical wiring passing thru the nacelle strut to the engine. Some access panels serve as pressure relief doors to prevent structural damage in the event of an increase in internal pressure. All access panels are secured to structure with a lanyard.
 3.  Fairings________
 A.  Fairing panels are installed to aerodynamically smooth the nacelle strut to the wing. Fairings are removable for access to nacelle strut attach points.
 B.  Forward Fairing (Fig. 2).
 (1)  
The forward fairing is a stream-lined cowl, which fairs the forward bulkhead to the fan cowl support beam. Removal of the the forward fairing provides access to the front of the strut forward bulkhead and the forward electrical and fluid connections. The forward fairing also incorporates a pressure relief door.

 (2)  
The forward fairing is attached at its forward end and along the sides with fasteners. The aft end is secured by clips to allow for strut and fairing motion.
