Airport Maintenance Practice (Section Three)
This manual is organized in such a way as to cover primarily the airport maintenance task required for maintaining safe aircraft operation during the landing, taxi and take-off phases. In addition, some of the maintenance tasks supporting the airport efficiency have been included.
The requirements for safety reason dominate the first part of the manual’s contents, wherein the  maintenance of visual aids, of electrical infrastructure, of pavements, of unpaved areas and of the drainage system is dealt with. CHAPTER-2 PERSONNEL:
The task of maintaining lighting aids should be entrusted only to reliable and skilled electricians who have had experience with high voltage, series circuits and lighting. These individuals should be present or on call during the operating hours of the airports to correct any  deficiencies  that might develop. Training programs should be established to maintain the competence of maintenance personnel and to keep them abreast of new developments.
The surface of a runway should be maintained  in a condition that precludes harmful  irregularities  or breaking off of pieces that would be a hazard to aircraft operation. Reference is made to Annex-14. 9.4.3. This specification requires continuous  monitoring of pavement condition, sand repair when necessary. Repair of pavement is costly and often imposes restrictions on the airport traffic even when damaged areas are small. Preventive  maintenance  is therefore of high importance for airport pavement management. CHAPTER-5 DRAINAGE
Drainage of the airport area is necessary:
- To maintain sufficient bearing strength of the oil for the operation of vehicles and/or aircraft at any time during the year;
- To minimize the attraction of birds and other animals representing a potential hazard to aircraft.
