GENERAL.
This airplane is configured with a single passenger/crew door on the right side of the fuselage, over the wing. Access to the baggage compartment is through a small door also on the right side, just aft of the wing. Emergency egress is assisted by an emergency exit incorporated into the crews' left window.
DOOR SEAL SNUBBER.
REMOVAL AND INSTALLATION OF DOOR SEAL SNUBBERS. (Refer to Figure 52-1.)

1.
To remove old seals use a thinner. such as toluol, that won’t affect the painted surface, and strip off the old seal.

2.
Install the door seal as follows:

A. If the surface has just been painted, allow to dry for a minimum of 2 hours before installing the seal.
B. Wipe the surface clean with a cleaner solvent, such as DuPont Prepsol 3919S.
— Note —
Refer to the List of Consumable Materials in Chapter 91 for types of appropriate neoprene adhesive.
C. Make sure both the seal and surface are 65° to 100°F.

D.  Adhesive should only be applied to that area to be covered by the seal.  If necessary, tape off the affected area.  The adhesive can be thinned as required with toluol.  Apply adhesive in a continuous coat of .002 to .010 of an inch thick.
E.  Apply a continuous coat of adhesive of the same thickness to the seal.
F.  With the adhesive applied to the mating surface and seal, allow them to cure 30 to 60 min. apart before bonding them in place.
G.  With reference to Figure 52-1, make sure the seal is properly aligned before allowing the surfaces to come in contact. The seal should not be stretched or pulled such that the cross section of the seal is reduced or distorted. Make sure the door closes properly and that an airtight seal is produced.
H.  After positioning the seal, apply pressure to remove air bubbles and assure firm contact.
