Federal authorities have asked the Melbourne International Airport to stop construction on an about $8 million hangar, citing concerns the building would impair a signal from a navigation system, reports Florida Today.

Airport officials say they are working with the Federal Aviation Administration and expect to reach an agreement within a week to prevent any delay of construction of the MidairUSA hangar. The FAA in November sent the airport an objection letter halting “vertical construction” indefinitely.

“As a result of the aeronautical study, the FAA determined that the proposed structure would be a hazard to air navigation,” an FAA statement says. “The FAA has requested additional information, and is working on a plan to mitigate the building’s impact on the VOR (navigation), which is required before construction can resume.”

The airport last year hired W&J Construction of Rockledge to build the 87,000-sq. ft. facility, which will be leased to Midair, at a cost of about $7.7 million. Vertical construction of the hangar, what is drawing concern from the FAA, has not yet started.
