AIRFIELD LIGHTING February/March 2018 airportbusiness 23 Runway light torqueing became a major issue after a high profile case in 2014 where a Delta Air Lines 747 was impaled by a loose light while taking off from John F. Kennedy International Airport (JFK). Stutz said it's important for airports to put a program in place to make sure staff are validating the torque on a regular basis and making sure it meets the requirements set forth by the FAA. Airfield lights can also take damage from the elements and during runway maintenance, which can create some issues with the quality of the light being produced. "I can't let a light sit in the field for seven years and not really know what the degradation is of the light output," Stutz said. "It's stuff on the prism, it's muck caking on the light window because some of these fixtures have negative slope, so you have water and debris and dirt going into the prism and then you get this film on the light prism." Stutz said airports can use photometric airfield testing equip- ment on a regular basis to check the quality of the light output from each unit. The equipment can be pulled down a runway and light output measured from each unit and compared to FAA standards. "Ground airfield lighting maintenance has evolved from replac- ing a light to now I have to do much more different things that are requiring a little more technology," he said. Stutz said airports can also consider an asset management system for tracking airfield lighting repairs. After workers perform maintenance and torqueing on a light fixture, the job is logged and sent to a database. The information allows staff to look at trending data and verify assets are being inspected on a regular basis and placed in spec with manufacturer recommendations. "It's about knowing what's out there and making sure the tool is as simple as possible to use and it's not adding a huge workload to my already strapped maintenance team," Stutz said. Keeping all of the torqueing information in one database helps with FAA Part 139 inspections, Stutz said, because it provides all the information the agency requires from airports. "Torqueing of light fixtures is not an easy, simple task, especially if they are having to do it every three months or so," Stutz said. PHOTOMETRIC CALIBRATION EQUIPMENT Preparing for maintenance with an LED lighting field requires edu- cation about the regulations before getting equipment, Stutz said. Once an airport learns what will be expected of it to maintain its airfield lighting systems, it helps leaders determine the type of equipment it needs to meet the standards. Utilizing the equipment also requires staff to learn how to use it even though some might only touch it a couple of times per year, Stutz said. Companies like ADB Safegate do offer the testing as a service and will send teams to work with airport maintenance officials to perform the inspections so the airport doesn't need to provide highly specialized training to a handful of workers. "It's not something that if you aren't experienced with doing it then you almost have to have someone whose gone to specialized training or you have to hire someone as a service level agreement to do that for you," he said. "The next part is you're asking me then to learn a new tool; something I don't have experience with and for something like the photometric one that I may only touch twice a year. Now I have to have a team that does photometric testing of airfield lighting, so is it a purchase decision or do I do it as a service."
