Policy proposal

What we are proposing to change, why and how we are proposing to change it:

What we are proposing to change:

We propose to amend UK Regulation (EU) No. 1321/2014 to reflect developments in aircraft and training technologies. This will enable engineers to maintain innovative aircraft, update module syllabuses to reflect changes in technology on conventional aircraft and enable Part-147 organisations to make the most of new technology and teaching methods.

We also propose updates for On-the-Job Training (OJT), enabling a smoother transition between licence (sub)categories and corrections of previous errors.

Why and how we are proposing to change it:

The current regulation wording is designed for conventional aircraft and assumes that propulsion is mostly provided by piston or turbine engines using fossil fuel. There are ageing aircraft that are no longer in production and where there are no longer Part-147 approved organisations offering type training. The proposed updates aim to address these problems by [insert]

Many of the amendments to Part-147 aim to eliminate or reduce fraud cases in examinations conducted by Part-147 maintenance training organisations (MTOs) for the obtainment of aircraft maintenance licences. We will do this by [insert some high level approaches]. It also aims at improving the structure and readability of Part-147 while ensuring a greater consistency with the other Annexes to UK Regulation (EU) No 1321/2014, in particular in relation to management systems.

New training methods and new teaching technologies are already being utilised by training organisations. The regulation needs to be updated to account for these methods and technologies to ensure efficiency and oversight of these methods and technologies.

There are margins for improvements as regards the structure of the modules, and the submodules deserve a more logical subdivision for a better harmonisation and to enable a smoother transition between licence (sub)categories.

These amendments also include combining and updating modules to reflect the latest developments in areas such as Safety Management, Human Factors, Aviation Legislation, Aeroplane Aerodynamics, Structures and Systems and Electronic Fundamentals.

On the Job Training is also being amended to enhance the efficiency of training for a first type rating.

Annex I (Part-M), Annex II (Part-145), Annex Vb (Part-ML) and Annex Vd (Part-CAO) are updated to correspond to the above changes.

6. Do you agree with the proposed amendments to UK Reg (EU) 1321/2014 to introduce these changes?
(Required)

If you answer No, you will have an opportunity in this consultation to comment against each proposed change or the proposal generally.

Where you disagree with a specific proposal, please ensure that you set out in the relevant section why you disagree and what you would suggest instead. You do not need to respond to each section unless you wish to.

7. Do you/your organisation require these new requirements to take effect at a different time from the one that has been proposed?

It is the CAA’s current intention to bring in many of these changes 2 years after the date the Statutory Instrument is made, with some coming into force sooner where appropriate. We anticipate the following timeframes:

  • Q1 2027:
    • An amending SI is laid in draft, approved by both Houses and made into law;
    • Certain elements, such as reporting requirements and requirements on the CAA will come into force within the first year following the laying of the SI.
    • A 2-year transition period begins after the SI for the remainder of the provisions to allow for familiarisation, training and updates to operating manuals, expositions and management systems etc.
  • Q1 2029:
    • All provisions will come into force;
  • Q1 2031:
    • To account for lengthy training programmes, for training that was begun on the current syllabus prior to the coming into force date, certificates of recognition of these courses will continue to be recognised for up to 4 years following the coming into force date.

If yes, please indicate:

(1) the reasons that a different timeframe for the implementation of these changes is required;

(2) the implementation period you consider would be appropriate.

8. Do you/your organisation require any additional transitional measures apart from the proposed delay before the amendments come into force?
