FAN COWL PANEL - MAINTENANCE PRACTICES (OPENING/CLOSING)
________________________________________________________
 1.  General
_______
 A.  There are two tasks in this procedure. The first task opens the fan cowl panels, and the second task closes the fan cowl panels. These two tasks are for the inboard and the outboard fan cowl panels.
 B.  The hold-open rod and the stabilizer rod hold the fan cowl panel open. The one end of the rods attaches to the fan cowl panel with a bolt. The other end of the rods attaches to a stow bracket on the fan cowl panel when the fan cowl panel is closed. When the fan cowl panel is open, the aft rod attaches to a bracket on the fan case and the forward rod attaches to a bracket on the aft bulkhead of the inlet cowl. The rods extend when the fan cowl panel opens.
 C.  When the rods are fully extended, it is necessary to lock the rods. If the rods are not locked, an injury can occur.
