FAA Issues Directive To Boeing 737 Planes Operators To Inspect Possible Switch Failures

By John F. Heerdink, Jr.

As per reports, the Federal Aviation Administration has issued a directive to operators of all Boeing Co (BA) 737 series airplanes to conduct inspections to check possible failures of cabin altitude pressure switches.

The directive includes 2,502 U.S.-registered airplanes and 9,315 airplanes worldwide and requires operators to conduct repetitive tests of the switches and replace them if needed. The investigation was raised after an operator reported in September that both pressure switches failed the on-wing functional test on three different 737 models. Failure of the switches may result in the cabin altitude warning system not activating if the cabin altitude exceeds 10,000 feet, where oxygen levels become extremely low. 

Boeing said it supports “the FAA’s direction, which makes mandatory the inspection interval that we issued to the fleet in June”.

The FAA directive did not report any in-flight failures of the switches. The FAA issued orders for tests to be conducted within 2,000 flight hours since the last conducted test of the cabin altitude pressure switches, before airplanes have flown 2,000 hours, or within 90 days of the directive. The directive includes all versions of the 737 jetliners, including the MAX, and is unrelated to any issues related to the MAX’s return to service last November.
