RLI ALS 200kW Outdoor EG with Subbase Tank
Louisville, KY · near Louisville Muhammad Ali Intl (1.3 mi)
What this outcome means
The FAA sent the case back to the filer rather than issuing a determination. This is the most common non-clean outcome and usually means something has to change or be supplied before the study can finish — not that the project was refused.
The proposal, in the filer's words
"A new outdoor EG with subbase tank is planned to be installed to support the RLI ALS due to lifecycle requirements. The outdoor EG will likely have a structure height less than 20ft but 20ft was entered to account for possible design changes."
