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 construction of vestibule addition on Bldg 211. Crane needed during construction. Construction start in summer 2026."
