AMCAcceptable means of compliance
AMC1 to Appendix II to Part-ML — Limited pilot-owner maintenance
(a)The lists below specifies items that may be expected to be completed by an owner who holds a current and valid pilot licence for the aircraft type involved and who meets the competence and responsibility requirements of Appendix II to Part-ML.
(b)The list of tasks may not address in a detailed manner the specific needs of the various aircraft categories. In addition, the development of technology and the nature of the operations undertaken by these categories of aircraft may not always be adequately considered.
(c)Any other task meeting the requirements of Appendix II to Part-ML may also be performed by the pilot-owner.
(d)Therefore, the following lists are considered to meet the representative scope of limited pilot-owner maintenance referred to in ML.A.803 and Appendix II to Part-ML:
(1)Part A applies to aeroplanes;
(2)Part B applies to rotorcraft;
(3)Part C applies to sailplanes and powered sailplanes; and
(4)Part D applies to balloons and airships.
(e)Inspection tasks/checks of any periodicity included in an approved maintenance programme can be carried out provided that the specified tasks are compliant with the basic principles of Appendix II to Part-ML. The content of periodic inspections/checks, as well as their periodicity, is not regulated or standardised in an aviation specification. It is the decision of the DAH or the declarant of a declaration of design compliance to recommend a schedule for each specific type of inspection/check. For an inspection/check with the same periodicity for different aircraft, the content may differ and in some cases, may be critically safety-related and need the use of special tools or knowledge and thus, not qualify for pilot-owner maintenance. Therefore, the maintenance carried out by the pilot-owner should not be generalised to specific inspections such as of a 50-h, 100-h or 6-month periodicity. The inspections to be carried out are limited to those areas and tasks listed in this AMC to Appendix II; this allows flexibility in the development of the maintenance programme and does not limit the inspection to certain specific periodic inspections. A 50-h/6-month periodic inspection for a fixed-wing aeroplane as well as the 1-year inspection for a glider may normally be eligible for pilot-owner maintenance.
TABLES Note: Tasks in Part A or Part B marked with ‘**’ exclude IFR operations following pilot-owner maintenance. For these aircraft to operate under IFR, these tasks should be released by an appropriate certifying staff.
