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 20-foot tall backhoe will be used to excavate a trench\nfor a proposed below ground force sewer service for a\nproposed hangar on a lease lot at Unalaska Airport. The\nnew sewer line will start from a proposed pump station\nat the hangar south of the southern apron and\nconnecting to existing sanitary sewer main north of\nAirport Drive with one angle point along the line. This is\na reapplication for previously approved cases 2024-AAL-\n1227-NRA 2024-AAL-1236-NRA and 2024-AAL-1237-NRA\nwhich have expired and the sewer line has not yet been\nconstructed. Cases were also revised to use stationary/fixed construction equipment structure type and coordinates confirmed with Google Earth per FAA NATER termination letter 3/6/26 2026-\nAAL-604-NRA."
