Airworthiness Directive 2026-13-04
one-timeAirworthiness Directives; Airbus Helicopters
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters modified by Supplemental Type Certificate (STC) SR00223IB. This AD was prompted by a report that several self-locking nuts of the window jettisoning system could be loosened by hand due to a non-conformity in the cable kit. This AD requires modifying an affected window into a serviceable window. This AD also prohibits installing an affected window or an affected door on any helicopter modified with STC SR00223IB. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2026-13-04 applies to
Applies only to H160-B helicopters modified by Supplemental Type Certificate (STC) SR00223IB having a date of issuance of the original airworthiness certificate or date of issuance of the original export certificate of airworthiness on or before October 3, 2024.
Whether AD 2026-13-04 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
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
