MECHANICAL TESTS OF FAA-E2491 AIRPORT IN-PAVEMENT APPROACH AND THRESHOLD LIGHTS

Static and impact load tests were performed on two style FAA-E-2491 airport in-pavement approach and threshold lights which were mounted in light bases encased in concrete. Static tests were conducted using either a 6-inch diameter steel plate or a rubber pad through which loads were applied to the center of the light optical cover assembly. Drop tests were conducted using a 5-lb steel ball which was directed to impact at various locations on the optical cover assembly. The old style lights were found to comply with load requirements for the current specification. The maximum load sustained by both style lights when loaded through a rubber pad was about two-thirds of the maximum load sustained when loading directly through the steel plate.
