Cessna 337 Baggage Door Retrofit
One of the biggest complaints concerning the Pressurized
Cessna 337 is the inaccessibility of the baggage area
behind the center seats. Although the area is approved
for 360 lbs. of baggage / cargo , any bags you carry
will have to be carried through the main entry door
then lugged over the center seats for storage.
R.T. Aerospace has solved the baggage problem on the
Pressurized 337s by the addition of a baggage door on
the fuselage aft right hand side. The door measures
approximately 20" x 20" with a fuselage opening
measuring 18" wide by 18.5" high. The door
is hinged at the top and opens up and outward for clear
access to the baggage area.
The baggage door is a composite buildup made from carbon
fiber-epoxy skins sandwiched around a 1" thick
Nomex honeycomb core. The latching mechanism consists
of three stainless steel lock pins spring loaded to
the locked position with an over-center cam. A key lock
is provided for additional safety and security. The
door and locking mechanism have been tested to over
10,000 cycles at an ultimate pressure load of 7 psi
with no damage or failures.
The fuselage modification consists of the removal of
existing frames and stringers in the door area and skin
cutout. It is then reinforced by the addition of an
external doubler and associated door jambs and internal
webs. The door sealing is accomplished via a blown seal
which provides positive door sealing at all times. Pressurization
for the seal is provided through an electrically driven
For greater ease of loading / unloading and versatility
of your Skymaster with much less frustration, the R.T.
Aerospace baggage door is a must.
