What to do

Operators of all Boeing Model 757 airplanes must perform a general visual inspection of specified lap splice areas and conduct repetitive DFEC inspections for cracks as outlined in Boeing Alert Requirements Bulletin 757-53A0111 RB dated May 21, 2018. Any identified cracks require applicable on-condition corrective actions. The AD became effective on May 22, 2019.

Summary

Correction to Airworthiness Directive 2019-07-04 issued by the Federal Aviation Administration (FAA) addresses all Boeing Model 757 airplanes. This directive requires inspections of the fuselage lap splice inner skins for scratch cracks that may interact with widespread fatigue damage (WFD), including general visual inspections and repetitive dual frequency eddy current (DFEC) inspections.

What changed

This correction republished the original AD 2019-07-04 in its entirety to include the previously omitted suffix "-04" in the AD title. The AD introduces mandatory inspections for scratch cracks at the lower fastener row of lap splices and clarifies affected airplane applicability, inspection areas, and compliance requirements.

Why it matters

The AD addresses a critical safety issue where scratch cracks could interact with multi-site damage fatigue cracking, potentially accelerating crack growth and compromising structural integrity. Compliance ensures continued airworthiness and safety of Boeing 757 fleets, impacting operators, maintenance organizations, and regulatory compliance teams.
