B. Installation of the Ceiling Panels at FR59 thru FR65

Ceiling Panels - Aft Cargo Compartment FR59/FR65 ** ON A/C NOT FOR ALL

NOTE: The installation of each ceiling panel is the same.

(1) Put the ceiling panel (2) in its correct installation position.
(2) Make sure that all the attachment holes align with the holes of the structure.
(3) Put all studs (3), (4) and (7) through the holes of the structure.
(4) Loosely install the ceiling panel (2) with the studs (3), (4) and (7).
(5) TORQUE the studs (3), (4) and (7) to between 0.060 and 0.055 m.daN (5.31 and 4.87 lbf.in )

NOTE: When you tighten the studs you will hear a click. This is a sign that you used the correct procedure to tighten the studs. This click is not a sign that correct torque value is applied. The applicable torque value must be between 0.055 and 0.060 m.daN in order to get 0.040 to 0.060 m.daN (measured on installed lining panel), because of to the compressible connection.
