What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757-200 and -300 series airplanes. This AD was prompted by reported crack findings on airplanes with scimitar blended winglets. This AD requires inspections for cracks, and repair as applicable. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2026-04-06 applies to
Applies to airplanes as identified in Aviation Partners Boeing Alert Service Letter APBSL757-0039 Rev IR, dated February 4, 2026.
Whether AD 2026-04-06 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
