The plenum area extends from the aft end of the nose area, aft to the second break
in the skin. The engine inlet plenum and assorted portions of the oil, fuel, and bleed
air lines are accessible with the plenum area cowlings removed. Access to the
plenum area is provided by a single upper cowling and two side cowlings (right and
left), all of which are removable by maintenance personnel.
The accessory area extends from the aft end of the plenum area, aft to the firewall.
The oil tank filler cap and dipstick, oil level sight glass, oil system scavenge pump,
FMU, fuel pumps, battery, and other engine accessories are accessible with the left
and/or right cowling doors open.
Access to the accessory area is provided by a right cowling door and a left cowling
door. The right cowling may be opened by releasing three thumb latches and one
lever latch. The left cowling may be opened by releasing one thumb latch and two
lever latches. The thumb latches are painted orange on the inner side to improve
visibility when open.
A cowling support strut is provided for each accessory cowling to prop the cowling
up in the open position. To support the cowling, place the rod end of the strut into
the receptacle on the firewall. To stow the strut, pull the rod end out of the
receptacle, press the strut end into the clip on the cowling, and close the cowling.
Press the latches to the closed position and verify no orange is showing on any of
the latches.
