EASA AD US-2026-01-05 — Wings - Aviation Partners Boeing (APB) Scimitar Blended Winglets Lower Stringer - Inspection / Maintenance Records Check
Summary
EASA Airworthiness Directive US-2026-01-05 is a final rule issued by the FAA addressing certain Boeing 757-200 and 757-300 series airplanes equipped with Aviation Partners Boeing (APB) scimitar blended winglets. The directive mandates inspections and maintenance record checks of the lower stringer areas on the wings to detect cracks and verify approved freeze plug repairs. This AD aims to ensure continued airworthiness by addressing potential structural cracking in critical wing components.
What Changed
This new airworthiness directive introduces requirements for a general visual inspection or maintenance records check for approved freeze plug repairs on specific wing lower stringers, followed by high frequency eddy current inspections for cracks in the affected areas. It also specifies on-condition actions based on inspection findings and clarifies inspection procedures around freeze plug repairs. The AD includes exceptions and clarifications based on stakeholder comments to ensure proper compliance and inspection methods.
Why It Matters
This directive is critical for operators and maintenance organizations as it addresses a known unsafe condition that could compromise wing structural integrity. Compliance ensures early detection and repair of cracks, preventing potential in-flight failures. Understanding the inspection nuances, especially around freeze plug repairs, helps maintenance teams perform accurate assessments and maintain regulatory compliance.
What To Do
Operators of affected Boeing 757-200 and 757-300 airplanes must perform the required general visual inspections or maintenance records checks and high frequency eddy current inspections as specified in the AD. They must also carry out any necessary on-condition corrective actions. Compliance with this AD is mandatory by February 20, 2026, the effective date of the directive.
