The Federal Aviation Administration is proposing changes to midair-collision warning devices on US aircraft after discovering a safety problem on a test flight.

The FAA, in a notice in the Federal Register, said it is proposing to mandate software upgrades to devices manufactured by a unit of L-3 Communications, Aviation Communication & Surveillance Systems.

The FAA is proposing the directive after reports of anomalies with the devices during a test flight over a high-density airport, according to the notice in the Federal Register.

The Wall Street Journal reported on Tuesday that the warning devices are in use on nearly 9,000 aircraft in the United States.
