Adjustment Of Pilot Door; 1G4; Shoulder Harness Inertia Reel Adjustment (Opt) - Piper Navajo PA-31 Service Manual

PIPER NAVAJO SERVICE MANUAL
NOTE
It is not a recommended check to place large volumes of water over
the aircraft exterior when specifically checking for door seal leaks,
as a window leak could appear as if the door seal was leaking.
CAUTION
The pilot door should not be opened from outside after performing
the leak check. as water standing on the scuff plate may have fallen
from the overhead seal. However, when opened from inside it can be
determined if the door is sealing satisfactorily.
p. The following may be used as an alternate to PRC 1221-2B Product Research Co. (GE RTV-102
silicon weather ban 101) and EC 847 (EC750 Carbolene Neroprene #F1) (1300L per PMS-C 10022-4).
q. Starting with aircraft 31-8012028 and up, door seal Piper P/N 486-089 is used. This new door seal
can be used in all aircraft with pilot doors installed.
NOTE
Seal P/N 486-089 may be stretched to reduce size to assist door
sealing, provided complete all-around seal is maintained.
4-83. ADJUSTMENT OF PILOT'S DOOR. (Refer to Figure 4-14.)
a. Remove trim panel from pilot's door to gain access to the latching mechanism. Open the door
and engage the support assembly.
b.
The outside door handle must be parallel with the airplane axis when the handle is in the fully
bolted position. The following steps will accomplish this.
1.
Disconnect the rod end (6) connected to the latch (7).
2. Loosen the locknut on the latch rod end and rotate the rod end to adjust the outside handle
to its proper position.
3. Connect the rod end to the latch and tighten the locknut.
c. With the handle in the fully bolted position, adjust the bottom latch to obtain the maximum
possible travel by adjusting the clevis rod end (19).
d. The top latch should be adjusted to obtain the best fit between the top of the door and the
fuselage skin when the door is closed and bolted. This is accomplished by adjusting the top latch rod end
(4).
e. Install the interior trim panels.

of the plastic cap, and set cap aside.
c. Unwind the harness completely, then measure and mark the harness 24 inches from the reel center.
d. Wind the harness onto the reel until the 24 inch mark is reached, then hold reel and place cap with
spring over the reel shaft end.
e. Aligning slot in shaft with spring tang, wind spring 6 turns
1/2 turn and snap the plastic cover into
holes in reel end shaft.
