Is your airport conducting proper routine maintenance on airport owned visual glide slope indicators, such as VASIs or PAPIs?
How does it work?
14 CFR Part 139.311(c) states the certificate holder must properly maintain lighting systems on the airport, which are owned by the airport. This includes ensuring that each item of lighting is clean, functional, and provides an accurate reference to users. If your airport owns any VASI and/or PAPI systems, it is your responsibility to keep this equipment functioning within manufacturer specifications. VASIs and PAPIs require specific routine and preventative maintenance that cannot be overlooked in order to maintain the integrity and accuracy of the visual signal. If FAA Airway Facilities (AF) owns VASI/PAPI systems at your airport, AF specialists will complete the required maintenance. Although FAA cannot directly perform maintenance on your VASI/PAPI system, AF specialists can be a good source of information on proper maintenance.
