What to do
Operators of Boeing 757-200, -200PF, and -200CB airplanes must perform a maintenance records check or physical inspection of the MLG outer cylinders by November 6, 2025. If any affected outer cylinders are identified, they must be replaced following the procedures in Boeing Alert Requirements Bulletin 757-32A0216 RB dated January 26, 2024. Requests for alternative methods of compliance can be submitted to the FAA as specified.
Summary
The Federal Aviation Administration (FAA) Airworthiness Directive 2025-19-11 addresses all Boeing Company Model 757-200, -200PF, and -200CB series airplanes. This directive requires a records check or inspection of the main landing gear (MLG) outer cylinders due to reports of improper grinding causing possible heat damage. The directive mandates replacement of any affected outer cylinders to ensure continued airworthiness.
What changed
This new airworthiness directive introduces a mandatory inspection or records check to identify affected MLG outer cylinders on Boeing 757-200 series airplanes. It requires replacing any outer cylinders found to have been improperly ground and potentially heat damaged. The directive also clarifies that installation of winglets per STC ST01518SE does not affect compliance.
Why it matters
This directive is critical for aviation professionals because heat damage to the MLG outer cylinders could lead to structural failure or collapse of the landing gear. Such failures pose serious safety risks including loss of airplane control or runway departure. Operators and maintenance teams must address this unsafe condition promptly to maintain aircraft safety and regulatory compliance.
