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

"T-Mobile proposes to replace antennas at approximately 28' centerline on this existing mall building that has an overall height of 41'. The mall building was built in 1996."
