The Federal Aviation Administration (FAA) has issued a new rule for certain Boeing 757 airplanes to fix a problem with a power transfer unit (PTU) control valve that sometimes fails to open. This rule requires changes to the wiring and installation of new relays near the PTU control valve. If not addressed, the issue could hinder the landing gear's ability to retract quickly during takeoff, adding extra drag and potentially leading to unsafe flying conditions. The rule becomes effective on February 14, 2025, and requires operators to follow specific Boeing instructions for making these changes.
Simple Explanation
The FAA wants to fix a part on some Boeing planes because it doesn't always work right, which could make flying unsafe. They say changes need to be made to make sure the landing gear works well, but figuring out how to follow their rules might be tricky without help.
