EASA AD US-2019-23-06: Superseded by FAA AD 2022-15-09

What to do

Operators of affected Boeing 757-200, -200CB, and -300 series airplanes must perform the required inspections and applicable on-condition repairs as specified in the AD. Inspections include a one-time general visual inspection and repetitive HFEC inspections of the fuselage frame web fastener holes. Compliance with this AD is mandatory by January 13, 2020, the effective date of the directive.

Summary

FAA Airworthiness Directive 2019-23-06 is a final rule addressing certain Boeing 757-200, -200CB, and -300 series airplanes. It mandates inspections for cracks initiating in the fuselage frame web at body station 1640, including visual and high frequency eddy current inspections, with applicable corrective actions. This directive aims to maintain structural integrity and safety of the affected aircraft.

What changed

This AD introduces mandatory inspections for cracks in the fuselage frame web at STA 1640, requiring general visual inspections for previous repairs and repetitive open hole HFEC inspections of fastener holes. It clarifies inspection applicability for freighter-converted airplanes and revises cost estimates for required actions. The AD also supersedes previous inspection requirements that were insufficient for detecting these cracks.

Why it matters

This directive is critical for operators and maintenance organizations to prevent structural failures due to undetected cracks in a key fuselage frame area. Compliance ensures continued airworthiness and safety of Boeing 757 aircraft, avoiding costly repairs or potential accidents. It also provides clarity on inspection scope and cost expectations, aiding in maintenance planning and regulatory compliance.
