ADR.OPS.C.015 Maintenance of visual aids and electrical systems Delegated Regulation (EU) 2020/2148 (a) The aerodrome operator shall establish and implement a preventive and corrective maintenance programme to ensure the serviceability of the electrical systems and the availability of power supply to all necessary facilities of the aerodrome, in a manner that ensures the safety, regularity and efficiency of air navigation. (b) The aerodrome operator shall establish and implement a preventive and corrective maintenance programme to ensure the serviceability of the individual lights and the aerodrome’s lighting systems reliability, in a manner that ensures continuity of guidance to, and control of aircraft and vehicles, as follows: (1) For a precision approach runway Category II or III, the system of preventive maintenance shall have as its objective that, during any period of Category II or III operations, all approach and runway lights are serviceable and that, in any event, at least: (i) 95 % of the lights are serviceable in each of the following elements: (A) precision approach Category II and III lighting system, the inner 450 m; (B) runway centre line lights; (C) runway threshold lights; (D) runway edge lights. (ii) 90 % of the lights are serviceable in the touchdown zone lights; (iii) 85 % of the lights are serviceable in the approach lighting system beyond 450 m; (iv) 75 % of the lights are serviceable in the runway-end lights. (2) The lights that may be unserviceable in accordance with point (1) shall not alter the basic pattern of the lighting system. (3) An unserviceable light shall not be permitted adjacent to another unserviceable light, except in a barrette or a crossbar where two adjacent unserviceable lights may be permitted. (4) For a stop bar that is provided at a runway-holding position and is used in conjunction with a runway intended for operations in runway visual range conditions less than a value of 550 m, the system of preventive maintenance shall have the following objectives: (i) no more than two lights shall remain unserviceable; (ii) two adjacent lights shall not remain unserviceable unless the light spacing is significantly less than that required. (5) For a taxiway intended for use in runway visual range conditions less than a value of 550 m, the system of preventive maintenance shall have as its objective that no two adjacent taxiway centre line lights be unserviceable. (6) For a precision approach runway Category I, the system of preventive maintenance employed shall have as its objective that, during any period of Category I operations, all approach and runway lights are serviceable and that, in any event: (i) at least 85 % of the lights are serviceable in each of the following: (A) precision approach Category I lighting system; (B) runway threshold lights; (C) runway edge lights; (D) runway-end lights; (ii) an unserviceable light shall not be permitted adjacent to another unserviceable light unless the light spacing is significantly less than that required. (7) For a runway meant for take-off in runway visual range conditions less than a value of 550 m, the system of preventive maintenance shall have as its objective that, during any period of operations, all runway lights are serviceable, and that, in any event: (i) at least: (A) 95 % of the lights are serviceable in the runway centre line lights (where provided) and in the runway edge lights; (B) 75 % of the lights are serviceable in the runway-end lights; (ii) an unserviceable light shall not be permitted adjacent to another unserviceable light. (8) For a runway meant for take-off in runway visual range conditions of a value of 550 m or greater, the system of preventive maintenance shall have as its objective that, during any period of operations, all runway lights are serviceable, and that, in any event: (i) at least 85 % of the lights are serviceable in the runway edge lights and runway-end lights; (ii) an unserviceable light shall not be permitted adjacent to another unserviceable light. (9) For a runway equipped with visual approach slope indicator systems, the system of preventive maintenance shall have as its objective that, during any period of operations, all units are serviceable. A unit shall be considered unserviceable if the number of unserviceable lights is such that the unit does not provide the intended guidance to the aircraft. (c) For the purposes of point (b), a light shall be deemed to be unserviceable if: (1) the main beam average intensity is less than 50 % of the value specified in the certification specifications issued by the Agency. For light units where the designed main beam average intensity is above the value specified in the certification specifications issued by the Agency, the 50 % value shall be related to that design value; (2) the filter associated with the light is missing, damaged, or the light does not produce the correct colour light beam. (d) The aerodrome operator shall establish and implement a preventive and corrective maintenance programme to ensure the serviceability and reliability of the system of markings and signs of the aerodrome, in a manner that ensures continuity of guidance to, and control of aircraft and vehicles. (e) Construction or maintenance activities shall not take place in the proximity of aerodrome electrical systems when low-visibility procedures are in effect at the aerodrome. (f) The aerodrome operator shall ensure that: (1) the preventive maintenance programmes referred to in points (a), (b) and (d) include appropriate inspections and checks of the individual elements of each system, and of the system itself, which are conducted in accordance with established procedures, and at defined intervals, appropriate to the intended operation and system; (2) appropriate corrective actions are taken to rectify any identified defects. (g) The aerodrome operator shall maintain records of the relevant maintenance activities.
