General
Before a Simple Task or minor scheduled line maintenance is certified or released, EASA requires that the authorized member of
the maintenance staff MM1 and/or member of the certifying staff CAT A MCM receives instruction in the tasks in accordance with
EASA AMC 145.A.30 (g).
The instruction in the tasks takes place by means of the successful completion of the Practical Logbook MM1/ CAT A MCM for the
applicable combination of aircraft type and engine, or, in the case of CA or IFE, the Practical Logbooks MM1/ CAT A MCM CA or
IFE. The content of these Practical Logbooks is defined by the type-specific task from the MM1/ CAT A MCM Task List.
Detailed instructions on working through each Practical Logbook are given in the applicable Practical Logbook. The type-specific
Practical Logbooks can be activated for individual members of staff by the responsible Training Coordinator in each case. (Prolog,
Practical Logbooks (LHT).)

ATA Chapter / Task
The CAT A MCM / MM1Task List has four columns, followed by an additional column for each aircraft type:

ATA Chapter / Task: Referencing of the task to the corresponding ATA chapter.
o The MM1/ CAT A MCM Task List is arranged according to the ATA specification, beginning with ATA Chapter 00
and ending with ATA Chapter 80.

Task: Definition of the individual Task Codes in the ATA chapters:
o LOC Location
o FOT Functional / Operational Test
o SGH Servicing and Ground Handling
o R/I

MM1 / CAT A MCM Task List

Nature: Basis of the definition of the individual Simple Tasks (pure instruction, typical task, additional task).
o Instruct:
These tasks are used in training, as the trainee works through the MM1 Practical Logbook. When the training is
successfully completed, the MM1 and CAT A MCM are permitted to perform these tasks. The tasks appear in
combination with another task (i.e. Removal/Installation), and are regarded as underlying basic tasks. The instruct
Tasks can be released by the CAT A MCM by observing and checking point 1.2 in this document.
o a – q:
Typical task which EASA has already classified as a "Simple Task". These typical tasks apply to every aircraft type
/ engine combination. Tasks a to q must be trained type-specifically (per aircraft type / engine combination) for all
MM1/ CAT A MCM authorizations.
 Exception: engine extension
 For an engine extension (e.g. A319, A320, A321 CFM 56 extension to A319, A320, A321 V2500), the
authorized person must be retrained in the engine-related tasks only.
 For this purpose, MM1/ CAT A MCM "Engine Extension" Practical Logbooks are provided. Their
content is type-specific with engine-related content.
o p & r:
These „Additional Tasks“ have been incorporated in the aircraft type / engine specific MM1/ CAT A MCM Task List
after approval by the German Aviation Authority (LBA). The Additional Tasks must be trained type-specifically for
all MM1/ CAT A MCM authorizations. Additional Tasks cannot automatically be transferred to other aircraft type /
engine-specific MM1/ CAT A MCM Task Lists. Instead, they are always approved by the LBA for specific types
only.

CRS: This task can be released to service by a CAT A MCM after performing the maintenance himself or herself.

1.2

Subject: Description of the Simple Tasks.

Aircraft type, e.g. A319/A320/A321 (V2500): (x) means that the Simple Task is available for this aircraft.
Typical "Simple Task" according to EASA AMC 145.A.30
The typical Simple Tasks for MM1/ CAT A MCM are listed according to EASA AMC 145.A.30 (g) Personnel requirements
under 1.4 – 1.6:
These tasks may be performed and signed for after completion of type-specific task training, with the maintenance
authorization MM1, during the processing of minor scheduled line maintenance (Weekly Check = S-Check) and simple defect
rectification, and the tasks can be released with the applicable CAT A MCM release-to-service authorization.
This means that the MM1 or CAT A MCM authorization must be used as follows:

The MM1 authorization permits the performance and sign off of maintenance for Simple Tasks or minor scheduled line
maintenance performed by the authorized person.

The CAT A MCM authorization permits the issue of a CRS (Certificate of Release to Service) only for MM1 maintenance
tasks performed by the authorized person. Excluding Safety Critical Items & Independent Inspections acc DOC.20615.

The authorization permits the authorized person to release an aircraft to service after "minor scheduled line
maintenance" (up to and including "Weekly Check / S-Check"), taking into account the CRS scope according to MM1/
CAT A MCM Task List DOC.37423.
