11-1. ENGINE COWLING.
11-2. The engine cowling is comprised of an upper
and lower cowl segment. A large access door on the
upper cowl provides access to the fuel strainer drain,
oil filler cap, and oil dipstick. Instead of attaching
directly to the fuselage, the cowling attaches to
shock mounts which are attached to the fuselage.
Quick-release fasteners are used at the cowling-to-
Shock mount attach points to facilitate detachment of
the cowling at the firewall. Screws fasten the upper
and lower cowl segments together at the nose cap
and quick-release fasteners are used along the side
parting surface s to hold cowling segments together.

11-3. REMOVAL AND INSTALLATION. Removal
and installation of the engine cowling is accomplished
by removing the attaching screws at the nose cap
dividing surfaces and releaSing the quick-release
fasteners at side parting surfaces and at shock mounts
of firewall. Disconnect electrical wiring to landing
light in nose cap cowling. Disconnect any air duct
and control linkage which interferes with removal
of the cowling. When installing the cowling, be sure
to connect any items disconnected during removal.
Make sure that baffle seals are turned in the correct
direction to confine and direct airflow around the
engine. The vertically installed seals fold forward
and the side seals fold upward.
