’Technical Information’, as defined in MAA02, comprises a wider range of
documentation than the civil aviation term ‘Maintenance Data’, which may be more
familiar to those AMOs familiar with traditional civil aviation processes. However,
within the context of its use in the RA4800-4849 Series (MRP Part 145), the term
‘Maintenance Data’ may be used in lieu of the term ‘Technical Information’ in such
AMO’s documentation.

10. The referenced procedure should ensure that when maintenance personnel
discover inaccurate, incomplete or ambiguous information in the Technical Information
they will record the details. The procedure should then ensure that the RA4800-4849
(MRP Part 145) approved maintenance organization notifies the problem to the
author/sponsor of the Technical Information in a timely manner.
11. A record of such communications to the author/sponsor of the Technical
Information should be retained by the RA4800-4849 (MRP Part 145) approved
organization until such time as the TAA or the MAA approved Design Organization has
clarified the issue by, for example, amending the Technical Information.
12. The referenced procedure should be specified in the Maintenance Organization
Exposition (MOE).

aircraft base maintenance, aircraft line maintenance, engine workshops, mechanical
workshops, avionic workshops, etc. Therefore, for example, engine workshops will
have a common system throughout such engine workshops, but this may be different
to the system used in aircraft base maintenance.
27. In the case of a lengthy maintenance task involving a succession of personnel
to complete such task, it may be necessary to use supplementary work cards or
worksheets to indicate what was actually accomplished by each individual person.
28. Where an AMO is contracted to use MOD Form 700 paperwork, the appropriate
processes in MAP-01 and MAP-02 must be used for their completion.
