Table 1-1.-Derivation of Lot Number
month and year of manufacture determined from
(date) will be the installed-life expiration date for
the CAD lot number. The resulting sum (date) is
the shelf-life expiration date of the CAD in
question.
Example:
Lot number/date of manufacture 0579
+ Shelf-life in years
+
6
Shelf-life expiration date
0585
Next, determine the installed-life expiration
date of the CAD by referring to the NAVAIR
11-100-1 series manual. Obtain the installed-life
figure (number of months or years), and add that
figure to the date (month) the CADs hermetically
sealed container was opened. The resulting sum
the CAD in question.
Example:
Date opened
0879
+ Installed life in months
+ 42
Installed-life expiration date
0283
Then, compare the two dates derived (shelf-
life and installed-life). Whichever date occurs first
is the CAD service-life expiration date.
Example:
Shelf-life
Installed-life
Service-life expiration date
0585
0283
0283
