FAA sets new directives for select Boeing 737 models

The Federal Aviation Administration (FAA) has issued new airworthiness directives (ADs) for certain models of the Boeing (NYSE:BA ) 737 aircraft. These directives, published in the Federal Register, address two separate concerns that could potentially affect flight safety.

The first AD targets specific Boeing 737-300 and -400 series airplanes. This directive comes after a report identified that the flight control rigging tolerances might not allow the spoiler to deflect to the minimal level required.

This level is necessary for the engagement of the cruise thrust split monitor within the autothrottle system. The FAA's directive aims to ensure that the spoiler deflection meets the essential safety threshold.

The second AD affects certain Boeing 737-8, 737-9, and 737-8200 (737 MAX) airplanes. The action follows a report detailing a non-conforming installation of spoiler wire bundles that could result in unintended spoiler movement.

Notably, there was an incident involving a flight spoiler hardover, which is an uncommanded and full deflection of the spoiler, a situation that can significantly impact an aircraft's handling and safety.

Both ADs are set to take effect on January 6, 2025. These measures are part of the FAA's ongoing efforts to maintain high safety standards and prevent potential issues that could arise from these identified risks.

The directives will require inspections and potential modifications to ensure compliance and enhance the safety of these Boeing 737 aircraft models.
