(2) Remove the window.
B. Installation
NOTE: In S/N’s 4636001 thru 4636076 only , if installing a service replacement pilot’s side window,
order Kit No. 767-355.
(1) Remove all traces of old sealant from the outboard side of the strap and the inboard side of the
fuselage window frame.
(2) All corners must be broken and all edges smooth and free of tool marks.
(3) Check fit the window to the fuselage window frame to ensure that it will fit. Trim excess material
as required.
(4) Apply sealant to the inboard side of the fuselage window frame.
(5) Position the window in its frame, apply sealant to the outboard side of the strap. Secure the
window to the frame and strap with the previously removed nuts, bolts and washers. Torque

C. 50 Hour Pilot’s Side Cockpit Window Inspection
For airplanes with pilot’s side cockpit windows which have accumulated 350 hours time-in-service,
upon reaching 350 hours and each 50 hours time-in-service thereafter, inspect as follows:
(1) Examine the exterior of the pilot’s side cockpit window in the area between the storm window
hinge and the fuselage skin.
(2) If sealant exists between the storm window hinge and the airframe skin, remove the sealant in
that area only, very carefully with a plastic scraper, ensuring that the window is not scratched.
NOTE: Replacing sealant after inspection is not required.
(3) Inspect the pilot’s side cockpit window in the area between the storm window hinge and the
fuselage skin for cracks. Especially examine the areas highlighted in Figure 3.
(a) If no cracks are found, make an appropriate logbook entry documenting completion of this
inspection and return airplane to service.
CAUTION: PRESSURIZED FLIGHT PROHIBITED WITH CRACKED WINDOW.
(b) If any crack is found, pressurized flight is prohibited until window is replaced as described
above.
NOTE: Unpressurized flight operations are authorized pending replacement of a cracked
window.
(4) In either case, for airplanes with pilot’s side cockpit windows which have accumulated 350
hours time-in-service, continue repetitive 50 hour inspections until such time as a permanent
solution is released (see future revisions of Piper Service Bulletin No. 1175).
