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
"New 11 990sf gross aircraft hangar."

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.
