These two recommended bulletins from Cessna require more lead time than most. The bulletin instructions require you to change the windlace around the cabin door. There are many colors of interior leather to choose from and each take about four weeks to fabricate. We advise that you place your order for the windlace as early as possible to prevent additional downtime.
For more information please contact Joe Austin at 800.525.2376 or Ed Johnson at 800.228.4277.
Cabin Window Replacement
— Joe Austin
Cabin window fogging is a problem that we see frequently. Structural integrity is almost never compromised, the issue is more of a cosmetic or nuisance squawk. The fogging comes from a warm air leak reaching the cold exterior window. A very small warm air leak can cause window fogging. Another reason for window fogging is related to the number of passengers in the plane and duration of flight at altitude.
If you see a recurring fogging problem on one or more windows after multiple flights, perform this very helpful procedure to help the technician when you go in for maintenance. When the window is fogged in nearly the same shape on each flight, with various amounts of passengers on board, use a grease pencil to trace the shape of the fogged section on the inner acoustic pane. Grease pencil will not damage the inner pane and can be easily removed. Depending on the size of the fogged area, the window may be replaced under warranty. Be sure to get approval from Cessna’s Warranty Department before any work is started.
Cabin windows are replaced as an assembly and sealed with a red 1/8” thick tape between the window assembly and the fuselage skin. We strongly suggest that the technician waits 24 hours or more before sealing the outside gap with proseal sealant.
During that 24 hour period the red seal gasses and will create bubbles in any exterior sealant applied too soon after installation.
Trivia Question
— Joe Austin
The previous question was: What were the names of the first two fully cantilever airplanes built by Cessna?
The answer: The first two fully cantilever planes that Cessna built were the “All Purpose” and the “Common.” The All Purpose was a 36’ wing span, 200 Hp Wright engine aircraft, shortly there aftercalled the “Phantom.” Development of the Phantom continued with a larger engine and another door to the fuselage. The plane was renamed again to the Cessna A model with 5 engines available (with different model designations: AA, AW, AS, AC and AF) due to the shortage of the Wright engine in 1927. The Common was a 47 foot wingspan, 200 Hp Wright engine aircraft. The Common was used to prove to the FAA that the design of the wing was strong enough to sustain flight. You may have seen an old promotional picture of the aircraft with men standing on top of the wing from tip to tip.
This edition’s question is: Where is eutectic salt used on most Citations?
The first 15 callers with the correct answer will receive a small gift. Call 800.525.2376 and ask for Joe Austin.
