SUBPART I AIRWORTHINESS REVIEW CERTIFICATE ( ‘ ARC ’ ) U.K.

ML.A.901 Aircraft airworthiness review U.K.

To ensure the validity of the aircraft airworthiness certificate ( ‘ ARC ’ ), an airworthiness review of the aircraft and its continuing airworthiness records shall be carried out periodically.

(a)

An ARC is issued in accordance with Appendix IV ([F24 CAA Form 15c]) to this Annex upon completion of a satisfactory airworthiness review. The ARC shall be valid for 1 year;

(1)

the [F25 CAA];

(2)

an appropriately approved CAMO or CAO;

(3)

[F4 the approved maintenance organisation while performing the 100-h/annual inspection contained in the AMP;]

(4)

[F4 for aircraft operated under Annex VII (Part-NCO) to Regulation (EU) No 965/2012 or, in the case of balloons, not operated under Subpart-ADD of Annex II (Part-BOP) to Regulation (EU) 2018/395 (3) or, in the case of sailplanes, not following Subpart DEC of Annex II (Part-SAO) to Regulation (EU) 2018/1976 (4) , the independent certifying staff while performing the 100-h/annual inspection contained in the AMP, when holding:]

(i)

(ii)

an authorisation issued by [F26 the CAA].

Whenever circumstances reveal the existence of a potential safety threat, the [F27 CAA] shall carry out the airworthiness review and issue the ARC itself.

(c)

The validity of an ARC may be extended maximum two consecutive times, for a period of one year each time, by an appropriately approved CAMO or CAO, subject to the following conditions:

(1)

the aircraft has been continuously managed for the previous 12 months by this CAMO or CAO;

(2)

the aircraft has been maintained for the previous 12 months by approved maintenance organisations; this includes pilot-owner maintenance tasks carried out and released to service either by the pilot-owner or by independent certifying staff;

(3)

the CAMO or CAO does not have any evidence or reason to believe that the aircraft is not airworthy.

This extension by the CAMO or CAO is possible regardless of which staff or organisation, as provided for in point (b), initially issued the ARC.

(d)

By derogation from point (c), the extension of the ARC may be anticipated for a maximum period of 30 days, without loss of continuity of the airworthiness review pattern, to ensure the availability of the aircraft in order to place the original ARC on board.

(e)

When the [F28 CAA] carries out the airworthiness review and issues the ARC itself, the owner shall provide the [F28 CAA] with:

(1)

the documentation required by the [F28 CAA];

(2)

suitable accommodation at the appropriate location for its personnel;

(3)

when necessary, the support of appropriate certifying staff.

Appendix II

Limited pilot-owner maintenance U.K.

In addition to the requirements laid down in this Annex, the pilot-owner shall comply with the following basic principles before it carries out any maintenance task:

(a) Competence and responsibility U.K.

(1)

The pilot-owner shall always be responsible for any maintenance he performs.

(2)

The pilot-owner shall hold satisfactory level of competence to perform the task. It is the responsibility of a pilot-owner to familiarise himself with the standard maintenance practices for his aircraft and with the AMP.

(b) Tasks U.K.

The Pilot-owner may carry out simple visual inspections or operations to check the airframe, engines, systems and components for general condition, obvious damage and normal operation.

A maintenance task shall not be released by the pilot-owner if any of the following conditions occurs:

(1)

it is a critical maintenance task;

(2)

it requires the removal of major components o r a major assembly;

(3)

it is carried out in compliance with an AD or an airworthiness limitation item (ALI) unless specifically allowed in the AD or the ALI;

(4)

it requires the use of special tools or calibrated tools (except for torque wrench and crimping tool);

(5)

it requires the use of test equipment or special testing (e.g. non-destructive testing (NDT), system tests or operational checks for avionics equipment);

(6)

it is composed of any unscheduled special inspections (e.g. heavy-landing check);

(7)

it affects systems essential for the instrumental flight rules (IFR) operations;

(8)

it is a complex maintenance task in accordance with Appendix III, or it is a component maintenance task in accordance with point (a) or (b) of point ML.A.502;

(9)

it is part of the 100-h/annual check (for those cases the maintenance task is combined with the airworthiness review performed by maintenance organisations or independent certifying staff).

The criteria referred to in points (1) to (9) cannot be overridden by less restrictive instructions issued in accordance with the AMP referred to in point ML.A.302.

Any task described in the aircraft flight manual (or other operational manuals), for example preparing the aircraft for flight (assembling the sailplane wings, or performing a preflight inspection, or assembling a basket, burner, fuel cylinders and an envelope combination for a balloon, etc.), is not considered a maintenance task and, therefore, does not require a CRS. Nevertheless, the person assembling those parts is responsible for ensuring that those parts are eligible for installation and in a serviceable condition.

(c) Performance and records of the pilot-owner maintenance tasks U.K.

The maintenance data, as specified in point ML.A.401, must always be available during the conduct of pilot-owner maintenance and must be complied with. Details of the data referred to in the conduct of pilot-owner maintenance must be included in the CRS in accordance with point (d) of point ML.A.803.

The pilot-owner must inform the contracted CAMO or CAO (if such contract exists) about the completion of the pilot-owner maintenance tasks no later than 30 days after completion of these tasks in accordance with point (a) of point ML.A.305.

Appendix III
