4.1 Objective The objective of the requirements of this clause is to ensure that persons who have responsibility for any activity, or are directly engaged in the maintenance of AGL constant current series circuits are competent to discharge those duties or perform those tasks.
NOTE It is recommended that the appropriate administration or aerodrome authority encourage the development of a formal and structured competency training programme(s). The training programme(s) should consist of multiple tiers that enhance progressively a person’s skills and ensure a recognised level of competency for those persons who have satisfactorily completed the programme(s).
4.2 Requirements
In accordance with national legislation, all persons involved in any activity, including manage- ment and maintenance activities, shall have the appropriate and verifiable training, technical knowledge, experience and qualifications relevant to the specific duties they have to perform. In particular, where involved in work on constant current series circuits, they shall be knowledgeable of the specific risks and the safety procedures involved in the work. The training, experience and qualifications of all persons involved in any activity shall be justified taking into account all the relevant competence factors. The justification shall be recorded in appropriate documentation.
NOTE The following competence factors should be addressed when assessing and justifying the competence of persons carrying out their duties:
• engineering appropriate to the application area;
• engineering appropriate to the technology (for example, mechanical, electrical/electronic/software engineering);
• safety engineering appropriate to the technology;
• knowledge of the legal and safety regulatory framework;
• knowledge of the operational aspects related to the AGL system at the aerodrome;
• the consequences in the event of a failure of a constant current series circuit;
• the consequences of failure to adhere to safety procedures when working on constant current series circuits;
• the novelty of the design, design procedures or application;
• previous experience relevant to the specific duties to be performed and the technology being employed;
• relevance of qualifications to the specific duties performed.
5Management of maintenance activities5.1 Objective
The objective of the requirements of this clause is to detail the roles and responsibilities ofthose personnel engaged in maintenance activities on or near AGL constant current seriescircuits and the procedures to ensure that safety is addressed.
5.2Requirements
5.2.1Organisational roles and responsibilities
The aerodrome authority shall appoint one or more named persons to manage,supervise orundertake specific maintenance tasks. Those persons shall be identified on any applicablerecord or other documentation associated with the task.All persons involved in work on theAGL shall be aware of
. their role and responsibilities;
. their duties and how to perform those duties;. the procedures to be followed;
.contingency working arrangements.
The content of this clause is a minimum requirement.Annex A illustrates a model hierarchy ofa more structured and comprehensive maintenance organisation.
NOTE IEC 62143 contains details of requirements for the safety management of an AGL system at an aerodrome.
5.2.2Use of contractors
The aerodrome authority retains full accountability under these requirements for all workundertaken on an AGL constant current series circuit by a contractor. This accountability shallinclude where the AGL constant current series circuit, or part of it, is to be under the controlof a contractor.The aerodrome authority shall ensure that all other organisations,includingthe users and operators of the AGL and other applicable aerodrome facilities, are notifiedprior to the commencement of the work and the procedures used.Contractors and other non-aerodrome employees shall follow the safety rules and procedures provided by the aerodromeauthority (see 5.2.4).
5.2.3 Maintenance policy5.2.3.1concept
A maintenance policy shall be produced and implemented. The maintenance policy shallinclude the following aspects:
. the maintenance philosophy, that includes and takes account of
– the maintenance objectives;
– the operational requirements;
– the maintenance resources;
