What to do

Operators must perform repetitive surface high frequency eddy current inspections of the fuselage STA 1380 frame inner chord and identify the material as specified in Boeing Alert Service Bulletin 757-53A0101. Any detected cracks must be repaired before further flight. Compliance with the AD is required starting January 9, 2018, and inspections already performed according to the service bulletin before this date are credited.

Summary

FAA Airworthiness Directive 2017-24-10 is a final rule affecting certain Boeing 757-200, -200PF, and -300 series airplanes. It addresses reports of cracking in a specific fuselage frame inner chord and mandates repetitive inspections, material identification, and corrective actions to ensure structural integrity.

What changed

This AD introduces mandatory repetitive high frequency eddy current inspections for cracks in the fuselage station 1380 frame inner chord, requires identification of the material for certain airplanes, and specifies corrective actions if cracking is found. It also clarifies that installation of supplemental type certificate STC ST01518SE does not affect compliance and provides credit for inspections done prior to the effective date.

Why it matters

This directive is critical for operators and maintenance teams to prevent potential cargo door opening during flight, which could cause rapid decompression and compromise the airplane's structural integrity. Compliance ensures continued airworthiness and safety of affected Boeing 757 aircraft, reducing risk of in-flight failures and costly emergency repairs.
