(URGENT)
In plain language (FlightFinder summary)
The FAA is asked to immediately issue an urgent general notice to all affected air traffic managers, directing them to perform a visual inspection and aural test of the Minimum Safe Altitude Warning (MSAW) speakers in their facilities. This is to ensure that no devices have been placed over the speakers that could hinder, mute, or prevent the aural warning from being heard in operational quarters.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
