SUBTASK 53-11-37-610-061
(1) Make the periodic inspection described in INSPECTION AND DETECTION,
SUBJECT 51-00-51 to preclude or detect the early stages of corrosion. Missing fasteners,
white powdery or any discolored deposits are evidences of the existence of corrosion which
should alert operators that some corrective action is required. A corrosion prevention program
should be initiated to prevent the accumulation of corrosive products in order to minimize the
occurrence of corrosion.
SUBTASK 53-11-37-610-009
(2) Corrosion Inspection/Removal
(a) Following cleaning of suspected areas, a visual inspection utilizing bright lighting and
mirror is effective for identifying the existence of corrosion. In specific localized areas
where inspection by visual means is impossible or where extent of corrosion has to be
determined after visual detection, INSPECTION AND DETECTION, SUBJECT 51-00-51
for applicable method.
(b) Where corrosion exists (noticeable bulges of the skin or white deposits of corrosion
products at fastener heads or joint edges), refer to SRM 737-678 for details of corrosion
removal.
(c) For minor corrosion, to minimize the downtime of the airplane, the corrosion products
should be cleaned off, followed by an application of a corrosion inhibiting compound into
the affected area to retard the corrosion process. The finish system should be restored at
the next maintenance opportunity (STANDARD PREVENTIVE MAINTENANCE
PROCEDURES, SUBJECT 51-00-59).

(3) Application of Corrosion Inhibitors
(a) For details of application of water displacing corrosion inhibiting compound, refer to
STANDARD PREVENTIVE MAINTENANCE PROCEDURES, SUBJECT 51-00-59.
