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

"Constructing a ductbank from Cargo 7 to the power substation on the south side of S. 188th St. 40' height is for temporary construction equipment. OE/AAA doesn't allow multiple points so I used the one closest to the runways. All other points are on the attached survey document. Coordinates are to FAA 1A accuracy."

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.
