NSN RWY 10 & 28 FLOLS POWER SUPPLY REPLACEMENT

Construction or Services Scope, Design, and/or Study The power supply equipment for the Fresnel Lens Optical Landing System (FLOLS) requires replacement. RWYs 10/28 FLOLS Primary power supply is in need of replacement based on structural deterioration. Both sides of the runway show excessive age and wear. This includes the primary transformers, junction boxes, power control boxes, and all cable. Requesting completion on or before 15 MAR 2026. Flight Safety is degraded until repair is complete. Fresnel Lense Optical Landing System (FLOLS) is a trailer mounted system that provide pilots a visual indication of their glidepath in the terminal phase of flight to provide for a safe landing. At Chambers, the FLOLS are at each end of the RWY (10/28) and provide a 3 degree glideslope targeting the E-28 emergency arresting gear wire so a tailhook aircraft can catch the wire during an emergency landing. They operate 24 hours a day, 7 days a week. They are removed from the field in high / gusty wind conditions. If electrical infrastructure becomes inoperative, or must be secured due to unsafe conditions, the FLOLS cart will have no electrical power. There are no back-up power supplies for these carts. Impact to operations will be that all inbound aircraft emergencies by tailhook equipped aircraft will have no visual guidance for their approach to catch the arresting gear wire. This will lead to increased risks and hazards to aviation safety, increases in bolters (attempts to catch the wire but aircraft fails to catch it), emergency aircraft remaining airborne for a prolonged period jeopardizing aircrew / passenger lives and potential catastrophic damage to E-28 ar ...
