will prevent loss of aircraft mission capability due
to CAD service-life expiration.
EXPIRATION DATES
To determine service-life expiration dates,
both the shelf life and installed life must be
computed. First, compute the shelf life of the
CAD by using its lot number to determine the
month and year of manufacture. Refer to
table 2-2 to ensure correct interpretation of the
lot number since there are currently two methods
shelf life (number of months and years) for the
individual CAD from the NAVAIR 11-100-1
series manual. Add this figure (shelf life) to the
month and year of manufacture determined from
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
used to derive lot numbers. Obtain the established
Shelf-life expiration date
