(ARMY AND AIR FORCE ONLY)
PURPOSE: In order to identify and quantify corrosion trends for preventive or corrective ac-
tion in the fleet, additional data is required. Data gathering performed in accordance with this Appen-
dix allows detailed reporting of instances of corrosion that might occur over a broad range of airframe
and component external surfaces, within the scope of disassembly required for JACE.
EVALUATION PROCEDURE: The report of an aircraft's corrosion evaluation must remain
linked to that aircraft's JACE report. See Table E-1, Corrosion Prevention and Control Evaluation
Checklist. While performing the JACE, the evaluator shall inspect for and report corrosion-related
information as follows:
NON-AIRCRAFT ITEM INDICATORS.
2.1.1 Date arrived at current location/previous location/date arrived at previous
location. This information is based on entries in the aircraft logbook DA Form 2408-15. Use four digit
month/year format for dates. Use city or installation, state, country of location.
2.1.2 Operational environment. More than one may be reported. Narrative may
also be used for further description. Indicate the appropriate categories from among the following:
MARINE - The aircraft is based and/or operates within a few miles
220.127.116.11 URBAN INDUSTRIAL - The aircraft is usually in an area charach-
terized by regular periods of smog or smoke.
18.104.22.168 NON-COMBAT AWAY - The aircraft is,or has recently been in ex-
tended operation away from the maintenance base. Aircraft in field excercise or bailed to another
agency are often in this category.
RECENT DEPLOYMENT - The aircraft is, or has recently been in
22.214.171.124 FLOAT - The aircraft has not been flown recently and appears to
be a source of parts in controlled substitutions. The length of non-flying time and, if readily available,
information relating the cause for float status shall be included in the remarks column.
2.1.3 Local Prevention Program. More than one may be reported. Chapter 3 of
tri-service manual NAVAIR 01-1A-509/T.O. 1-1-691/TM 1-1500-344-23 details the features of a corro-
sion prevention program. One of the most important features is that the activities recur on a sched-
uled basis. Inquire among the local maintainers on the floor for answers to the following:
126.96.36.199 CORROSION PREVENTION COMPOUND IN USE - These com-
pounds leave an oily or waxy residue where applied, but are not to be confused with the working
fluids from power components that may have leaked. Use narrative to report the NSN of the primary
corrosion prevention compound in use.
ROUTINELY HANGARED - Aircraft is kept inside when not in use
and undrgoing maintenance.
