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

"Use of temporary crane-type equipment up to 75-feet above ground level used to install new 50' RCAG Tilt down communication tower 60' W of the existing FAA ASTI Building and associated facilities Construction dates are tentative for Summer FY27."

Screening a structure of your own?

Check Part 77 and the tower's line of sight before you file

LOS Analyzer screens a proposed structure against FAA Part 77 surfaces and the control tower's sightline to the runway, terrain-aware, in minutes. It is a preliminary screening — not an FAA determination and not a substitute for a licensed engineering review.
