EASA Requires Practical Training to be completed following the completion of every EASA Part 147 Type Training.
The following information is extracted from regulation 1321/2014 together with EASA Frequently Asked Questions FAQ
APPENDICES TO ANNEX III (Part- 66)
3.2. Practical Training
(a) Objective:
The objective of practical training is to gain the required competence in performing safe maintenance, inspections and routine work according to the maintenance manual and other relevant instructions and tasks as appropriate for the type of aircraft, for example troubleshooting, repairs, adjustments, replacements, rigging and functional checks.
It includes the awareness of the use of all technical literature and documentation for the aircraft, the use of specialist/special tooling and test equipment for performing removal and replacement of components and modules unique to type, including any on-wing maintenance activity.
(b) Content:
At least 50 % of the crossed items in the table*, which are relevant to the particular aircraft type, shall be completed as part of the practical training.
*See Annex III (Part-66) APPENDICES TO AMCs TO ANNEX III (Part-66) – Appendix II — Aircraft Type Practical Experience and On-the-Job Training – List of Tasks for Details
Tasks crossed represent subjects that are important for practical training purposes to ensure that the
Operation,
Function,
Installation and
Safety Significance
Of key maintenance tasks is adequately addressed; particularly where these cannot be fully explained by theoretical training alone.
NOTE – Although the list details the minimum practical training subjects, other items may be added where applicable to the particular aircraft type.
Tasks to be completed shall be representative of the aircraft and systems both in complexity and in the technical input required to complete that task.
While relatively simple tasks may be included, other more complex tasks shall also be incorporated and undertaken as appropriate to the aircraft type.
Glossary of the table:
LOC: Location;
FOT: Functional/Operational Test;
SGH: Service and Ground Handling;
R/I: Removal/Installation;
MEL: Minimum Equipment List;
TS: Trouble Shooting.
EASA FAQ
How should the 50% of tasks required for practical training be selected? Should it be 50% of tasks as per glossary (e.g. LOC, FOT, SGH, R/I, etc.)?
The selection of 50% of tasks cannot be selected according to the glossary. Paragraph 3.2 of Appendix III to Part-66 clearly states that ‘the tasks selected shall be representative of the aircraft and systems both in complexity and diversity.
In addition, the practical training should particularly address the tasks which cannot be explained by theoretical training only. While relatively simple tasks may be included, other more complex tasks shall also be incorporated and completed as appropriate to the aircraft type.
Regarding the way to read the table in paragraph 3.2, the lines aims at covering the main systems so that no line relevant to the particular aircraft type should be omitted in the selection. Inside each line applicable to the aircraft type, half or more of the crosses can be selected. From a learning point of view, selecting 2 simple tasks as LOC and SGH would not be “representative”, while selecting LOC and TS, for example, would be much more appropriate.
When selecting the tasks, the usage of filtering method based on the criteria similar to that described in AMC to paragraph 3.1(d) of Appendix III to Part-66, point 5 f) is recommended.

(f) During the analysis of these documents:
Consideration should be given to the following typical activities:
Activation/reactivation;
Removal/Installation;
Testing;
Servicing;
Inspection, check and repairs;
