FAA issues directive on Boeing 737 NG, MAX planes over potential fire suppression issue
The Federal Aviation Administration (FAA) on Thursday released a new safety directive for Boeing (BA.N) 737 Next Generation (NG) and MAX airplanes to address a potential issue with reduced fire suppression capabilities.
The FAA reports that some airplanes may not have an effective electronic flow control system for air conditioning packs that vent air into the cargo hold from other parts of the plane. According to the guidance, operators cannot transport cargo in the cargo hold if their aircraft are operating with this condition until they can verify that the cargo is not flammable or combustible.
According to the FAA, the directive applies to all Boeing 737 8, 737 9, and 737 8200 MAX airplanes, as well as some 737-800s and 737-900ERs.
Boeing did not immediately comment.
The airworthiness directive impacts 663 airplanes registered in the United States and approximately 2,204 worldwide.
Operators must comply with this directive beginning 10 days after date of publication.
