NOBE II - TC #1 - mobile crane - refile

What this outcome means
The FAA studied the proposal and concluded it would not be a hazard to air navigation. A no-hazard determination is not permanent — it carries an expiration date, and if the structure is not built by then the case has to be re-filed.
The proposal, in the filer's words
"This filing is for the mobile crane used to erect 1 of 2 tower cranes on site. This filing is for the erection of Tower Crane #1 ASN 2025-AEA-13977-OE. The mobile crane is a LIEBHERR LTM1650-8.1. The mobile crane will only be needed on site 3 days during the erection of the tower crane and 3 days during the dismantlement of the tower crane. The mobile crane will be mobilized on site approx 1/5/2026 when the crane is erected for 3 days and then again in the future approx. 7/5/2027 when the tower crane is dismantled. The 3 days the mobile crane would be mobilized could be any day Monday thru Sunday depending on when the erection of the crane is scheduled. The mobile crane will have red lights and flags and will be lowered from sun down to sun up and when not in use. As said above the crane will be used for 3 consecutive days during the erection of the crane and then for 3 consecutive days for the dismantlement of the tower crane."
