This page provides information to UK Part 66 Aircraft Maintenance Licence holders wishing to remove limitations from a basic category or sub-category of their existing licence.
Limitations introduced on an aircraft maintenance licence are exclusions from the certification privileges and, in the case of limitations referred to in point 66.A.45, they affect the aircraft in its entirety.
Limitations were applied to the holders of a BCAR licence, who converted their licences to a Part 66 licence upon the introduction of Part 66 under Part 66.B.305. Additionally, holders of an EU licence that converted their licence to a UK Part 66 licence during the EU Exit Withdrawal Agreement period, may have limitations applied to their UK licence, if these were present on the EU licence at time of conversion.
Limitations may also be applied to a Part 66 licence in accordance with 66.A.45 and 66.A.50, typically for aircraft in Group 3, 4 or Category L, where the holder cannot evidence appropriate experience of aeroplanes with all construction types.
Pre-Requisites
You must hold a current and valid Part 66 Aircraft Maintenance Licence with the relevant unrestricted Basic Category / Sub-Category on your licence and have met the requirements in accordance with UK 66.A.50(b).
Limitations may be on a Basic Category/Sub-Category, on an aircraft type rating or both.
The Part 66 Licence is not a progressive licence and therefore applications received for the removal of limitations from a Category/Sub-Category must have met the requirements to remove all the limitations endorsed on their Licence as you are unable to lift limitations singularly.
You must complete the relevant modules applicable to the limitations on the Basic Category/Sub-Category. These are shown in the sections below for the relevant licence category.
Part modules can be completed within an organisation appropriately approved to conduct the UK CAA conversion exams. Where a part module is not available from a UK Part 147 or from the CAA, a full module may be completed in place of the part module.
For the acceptability of EU/EASA Certificates of Recognition (CofR) please see Engineer licensing requirements after 1 January 2023
For aircraft in Group 2 or 3, if the aircraft type requires type examination (oral), we can assess the experience submitted without evidence of any course being completed.
You will be required to demonstrate a minimum of 6 months relevant practical maintenance experience appropriate to the limitations you are removing from the Category/Sub-Category. This can be demonstrated in the form of a logbook in the style of the CAP741, presented in ATA order, ensuring the tasks have been signed off by the appropriate signatory.
The recommendation document will need to be completed by a Quality Manager or the immediate senior person within the Quality Department of your current employer, or the organisation where the experience is gained.
The following examples provide the knowledge requirements that must be evidenced to remove limitations introduced to a Part 66 due to the conversion from a national licence (typically BCAR) at the introduction of Part 66.
A list of drop downs for each of the types of licence and the limitation exam requirements.
