ML.A.302(c)(3) Aircraft maintenance programme
ED
Decision 2020/002/R
ALTERNATIVE MAINTENANCE ACTIONS
‘Maintenance
actions alternative to those referred to in point (c)(2)(b)’ refer to when the
DAH’s ICA are used as the basis for the AMP development and the CAMO, CAO or
owner (as applicable), when developing the AMP, decides to deviate from
certain of these DAH’s instructions, introducing, for example, a less frequent
interval or a different task type (inspection instead of check) than the one
established by the ICA.
These
alternative maintenance actions shall not be less restrictive than those set
out in the applicable MIP. This means that the extent of the maintenance to be
covered by the deviating task cannot be less than the extent of the
corresponding task in the MIP in terms of frequency and task type.
Examples of
alternative maintenance actions:
|
ICA task |
AMP proposed alternative |
MIP task |
Alternative acceptable Yes/No |
|
Inspection XX 6 months interval |
Inspection XX 12 months interval |
Inspection XX 12 months interval |
Yes |
|
Inspection XX 12 months interval |
Inspection XX 24 months interval |
Inspection XX 12 months interval |
No |
|
Inspection XX 24 months interval |
Inspection XX 36 months interval |
Inspection XX 12 months interval |
No (24 months to be kept) |
|
Functional test system XX |
Operational test system XX (same interval) or
general visual inspection system XX (same interval) |
Functional test system XX (same interval) |
No* |
|
Operational test system XX |
Functional test system XX (same interval) |
Operational test system XX (same interval) |
Yes* |
|
Inspection XX 24 months interval |
Inspection XX 36 months |
None relevant |
Yes |
|
Functional test |
General visual inspection |
None relevant |
Yes |
*A
functional test is considered more restrictive than an operational test.
Remark: the
above does not apply to one-time interval extensions, for which ML.A.302(d)(1) provides 1-month or 10-h tolerance (i.e.
permitted variation) for aeroplanes, touring motor gliders (TMGs) and balloons
and 1-month tolerance for sailplanes and powered sailplanes other than TMGs.
EASA balloon maintenance programs can deviate from the Design Approval Holder's (DAH) Instructions for Continued Airworthiness (ICA) if the alternative maintenance actions are not less restrictive than the Minimum Inspection Program (MIP). This ensures continued airworthiness by maintaining or exceeding the MIP's frequency and task type. One-time interval extensions have specific tolerances.
