Structured OJT

On The Job Training in Istanbul 

Passed all EASA part 66 modules,

Required work experience logbook for the application with the form 19 for  basic licence, 

you are attending airplane type training, 

to be endorsed in your new EASA part 66 AML the On Job Training (OJT) from the EASA part 147 school

you must also present a Structured On Job Training (SOJT) conducted by an EASA part 145 maintenance organisation in Istanbul, Turkey


Available group is Monday 5th August 2019,

however we do have occasional cancellations and the availability could be earlier than this date.

The location will be at Ataturk Airport in Istanbul (IST).

The OJT places will be on a first come basis. I do require full payment up front before the start of the course.

There will also be pass requirements that will need to be undertaken for IST.

Here is some information which we give to interested OJT trainees.

As you are aware, as SOJT is quantity based rather than duration,

Trainees will be expected to follow the shift pattern and demonstrate flexibility as and when maintenance is performed.
Training packages for SOJT are in the region of ????? Euro per person for the 4-week SOJT, which compares favourably with other types of on aircraft training in Turkey.

The prices (for OJT) are based on intensive groups of three engineers assigned to a Qualified OJT Supervisor (as listed in the Part-145 MOE, Section 3.15).

It should be noted that it is beneficial for trainees to organise themselves into groups of three.
Prices are for training and access to the aircraft.

Accommodation, flights and associated expenses are the responsibility of the trainee.

We require a 60% deposit to enrol on the list 1-week before the start date, 40% before completion training. 

If you cannot attend, you will still be liable for costs. This is on a sliding scale, dependent on the notice you give.

With regards to the our OJT programme, there are several points which we would like to draw your attention to. Please ensure you read and understand fully. They are repeated in the contract and you will be expected to sign that you understand and accept the conditions.

1. Acceptance onto the Course

Please read with point 6, Competent Completion of Maintenance.

Trainees are expected to be ready to complete the final part of the necessary training to endorse their Part-66 licences with the first type. We will need documentary proof for certain items.

You will be interviewed by the Head of Training (or an accepted deputy) where your knowledge/experience of aircraft maintenance specific to the A320 will be checked.

You will be expected to prove previous recent maintenance experience on the A320 family (excluding the Part-147 type training).

2. Confirmation of Courses

We normally confirm courses 8-weeks (2-months) before the start date. We have to take into account the 6-week duration and the maintenance schedule of the aircraft (supplied by the airlines). If there will be insufficient maintenance planned during the placement, you will be unable to meet the requirements of Part-66 and therefore the course may be cancelled/postponed. Trainees are reminded to prepare for such eventualities.

3. Flexibility of Hours

The nominal working plan is Monday to Thursday evening/nightshift. However you are required to be available 7-days a week to follow any additional maintenance tasks which we deem necessary for the completion of the OJT (normal human factors/working hour limits apply). Please do not make fixed plans for weekends.

4. Licences Not Issued by the Turkish DGCA

Where a basic Part-66 licence has not issued but the Turkish DGCA, the trainee will need to receive prior confirmation of acceptance by their licence issuing NAA that the OJT performed by Sinerji Aviation (  ). We can assist but there is an additional administrative charge in these cases.

5. Type Training Certificates

The trainees must be in possession of valid theory and practical certificates for the Airbus A318/A319/A320/A321 (CFM56) and Airbus A319/A320/A321 (IAE V2500). These must be within the 3-year expiry period (before type endorsement application). Ref Part-66, appendix III, section 6.

6. Competent Completion of Maintenance

"The objective of OJT is to gain the required competence and experience in performing safe maintenance." Part-66 Appendix III Section 6.

We expect trainees to have properly completed all of the necessary training required for basic licence issue and successful completion of type training for the A320 Family (CFM56 and V2500).

We are not in a position to teach basic hand skills, knowledge of AMM, TSM, IPC, MEL/CDL and other related manuals or other skills expected of Part-66 licence holders.

While you complete tasks, the OJT supervisor will sign and stamp for the successful completion of the task, once they are satisfied that the trainee is capable and competent of completing the task safely in the future when not under supervision. If the supervisor is NOT satisfied of your performance, the task will NOT be signed and stamped and this may impact the successful completion of OJT.

Trainees will be constantly assessed for the required competence and experience while performing safe maintenance and feedback given as necessary.

If you do not meet the expected criteria and through our assessment procedures, are not in a position to complete the required OJT within the placement duration, you will be informed, with objective evidence given to support our position.

Examples of which (but this is not exhaustive):

· Skills. Inability to use basic hand tools or perform basic maintenance operations. Unable to use maintenance documentation.

· Knowledge. Lack of level III maintenance knowledge of the A320 aircraft gained during the type training. Being unable to locate main servicing locations/components or interaction with the aircraft systems.

· Attitude: Performing unsafe acts at anytime which could endanger yourself, other engineering staff, the aircraft and crew and passengers. Not adhering to warnings or cautions or generally poor attitude in the maintenance environment.

Please remember that trainees must meet required standards before certificates are issued. We will supply enough maintenance tasks to comply with OJT providing that the trainee meets the required standards.

7. Visas and Airport Passes

It is the responsibility of the trainees to gain the necessary visas (if applicable) to Turkey and supply sufficient and correct references for airport security passes.

We advise all trainees to ensure that all paperwork is completed truthfully and correctly. Sinerji Aviation cannot be held responsible for a trainee being refused access into Turkey or the airport where the SOJT is being performed.

Additionally, it is the trainee's responsibility to abide by all the necessary airport rules and regulations while in possession of a temporary airport pass.

Sinerji Aviation cannot be held responsible for a trainee's pass being removed if they do not follow the correct procedures.

8. Summary:

These are intensive placements designed for experienced Part-66 holders who are ready to be certifying licensed engineers who have previous recent maintenance experience on the A320 family

Sinerji Aviation will provide the necessary tasks to meet the requirements of Part-66.

However, if trainees do not meet the requirements of the Part-66 regulations (in regards to not demonstrating the required competence and experience), they will not be issued with a Certificate of Completion (Compliance Report) necessary for first type endorsement.


We wish to assist all trainees with their professional development. The above points are to protect all parties (Sinerji Aviation and trainees) from any issues arising from a trainee's inability to comply with the applicable sections of Part-66.

Visit to check on your visa requirements. We suggest that if you need a visa, you do take professional advice.

Please note: The duration, prices and group sizes are non-negotiable.

We do not wish anyone to be disappointed, the training is an expensive and requires commitment. If you need any clarification or have any questions, please ask before entering into contractual terms with Sinerji Aviation Inc.

If you are interested in a OJT place then please contact me.

I look forward to hearing back from you.

How can I carry out my OJT in a Part-145 approved maintenance organisation (AMO) whose principal place of business is located outside the EASA Member States?


The endorsement of the first aircraft type rating, within a given category/sub-category, requires satisfactory completion of the corresponding On-the-Job-Training (ref. 66.A.45.(c)).

The OJT shall be approved by the competent authority who has issued the licence (ref. Part 66, Appendix III, sec. 6).

It shall be carried out in a maintenance organisation approved under Part-145 (or M.A. Subpart F) with A rating and the procedures for OJT should be included in the exposition (MOE chapter 3.15 “OJT procedure”) approved by the competent authority of the maintenance organisation. However, since these procedures are approved by the competent authority of the maintenance organisation, and providing training is not one of the privileges of a maintenance organisation, they can only be used when the licensing authority (competent authority issuing the license) is the same as the competent authority of the maintenance organisation. In other cases, it is up to the licensing authority to decide whether it accepts such procedures for the purpose of approving the OJT (ref. AMC to Section 6 of Appendix III to Part-66).  

For the Part-145 AMOs, whose principal place of business is located outside the EASA Member states, the competent authority of the maintenance organisation is EASA. In such case, the OJT procedures cannot be included in the MOE, due to the fact that EASA is not a licensing authority. 

The possibility still exists in this case that a licensing authority may directly approve OJT procedures, which have to be included in a separate document outside (and not being part) of the MOE.

Consequently, personnel working in these AMOs, or the AMOs wishing to support its staff on this matter, should:

  • Option A: apply directly to the licensing authority who has issued the license for the approval of an OJT (to be proposed in a document outside the MOE). This option should normally be considered by organisations and not by individuals.
  • Option B: find an agreement to follow an already approved OJT at another organisation, which was approved by the same licensing authority who has issued the license. Possibility also exists to follow an OJT which was approved by any other licensing authority, however in such case the final acceptance of this OJT for the purpose of endorsing the first type rating in the license remains at the sole discretion of the competent authority issuing the license.

It is recommended that prior to starting any OJT, the licensing authority who has issued the license is contacted to verify its acceptance of any possible intended option.
