2. Clean the Acoustic Surfaces of the Thrust Reverser
__________________________________________________
A. General
(1) Special attention should be given to prevent water and cleaning agents from entering the honeycomb cells of the acoustic panels. Follow the steps below to minimize the ingestion of cleaning solutions and water into the acoustic panels.
CAUTION: WATER AND CLEANING AGENTS TRAPPED INSIDE THE PANEL WILL
_______ LEAD TO CORROSION OF THE ALUMINUM HONEYCOMB CORE.
(a)
Wipe cleaning solutions on with a clean cloth, damp, but not saturated, with cleaning solution.
(b)
Wipe with a clean cloth, damp with water, to remove all residues.
(c)
Wipe using a clean dry cloth to remove all moisture.
(2) Use ONLY cleaning agents certified to the requirements of Document
____ D6-17487, Evaluation of Airplane Maintenance Materials, when cleaning acoustic panels.
CAUTION: DO NOT SUBJECT AREAS CONTAINING PERFORATED SKINS TO HIGH
_______ PRESSURE SPRAYING, OR SUBMERGE IN SOLVENTS OR WATER.
(3)
If pressure washing is required for components around acoustic panels, the acoustic portion of the nacelle should be covered to prevent ingestion of the cleaning solutions.
(4)
Do not vapor-degrease Graphite/Aramid epoxy structures with chlorinated cleaning agents such as Methylene Chloride, Trichloroethylene, and Trichloroethane.
