EASA AD US-2020-01-18
[Correction] Time Limits / Maintenance Checks - Airworthiness Limitations Instructions - Principal Structural Elements - Inspections / Maintenance or Inspection Program Revision
Summary
Correction to Airworthiness Directive 2020-01-18 issued by the Federal Aviation Administration (FAA) affecting all Boeing Company Model 757 airplanes. This correction clarifies the proper reference for revising the maintenance or inspection program related to airworthiness limitations and principal structural element inspections. The directive mandates incorporation of updated structural inspection requirements to ensure continued airworthiness.
What Changed
The correction updates the service information reference in the regulatory text from an incorrect general section to the specific Subsection B, “Airworthiness Limitations–Structural Inspections,” of the Boeing 757 Maintenance Planning Data Document, Section 9, Revision October 2018. No other changes to the original AD 2020-01-18 are made.
Why It Matters
Accurate referencing of maintenance documentation is critical for operators and maintenance organizations to properly revise inspection programs and comply with FAA requirements. This correction ensures that Boeing 757 operators use the correct structural inspection limitations, which helps prevent fatigue cracking and maintain structural integrity. It avoids confusion and potential non-compliance due to referencing incorrect maintenance data.
What To Do
Operators of Boeing 757 airplanes must revise their maintenance or inspection programs within 18 months after March 5, 2020, to incorporate the correct Subsection B of the Boeing 757 Maintenance Planning Data Document, Section 9, Revision October 2018. For airplanes with Supplemental Type Certificate STC ST01518SE installed, a supplemental program must be incorporated. No alternative inspection actions or intervals are allowed without FAA approval.
