(d) Subject Joint Aircraft System Component (JASC) Code 5630, Door windows. (e) Unsafe Condition 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. The FAA is issuing this AD to prevent failure of the jettisoning function of the window. The unsafe condition, if not addressed, could result in the inability to evacuate helicopter occupants during an emergency situation. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency AD 2024-0075, dated March 18, 2024 (EASA AD 2024-0075).

(2) Where EASA AD 2024-0075 requires compliance in terms of flight hours, this AD requires using hours time-in-service. (3) Where EASA AD 2024-0075 defines "affected passenger window" and refers to "a Part Number as listed in the MSB and an s/n as listed in the vendor SB", this AD requires replacing that text with "a part number identified in Planning Information, paragraph A.1 Effectivity, and a serial number identified in the Appendix: Applicable serial number, of Vision Systems Vendor Service Bulletin No. 02-050-015, Revision 0, dated January 24, 2024, as applicable".

(8) Where the material referenced in EASA AD 2024-0075 specifies "screw the nuts", this AD requires replacing that text with "secure the nuts into place". (9) Where the material referenced in EASA AD 2024-0075 specifies "fine tuning the pull-up cables in locked position (finger)", this AD requires replacing that text with "put the pull-up cables into the locked position and make small adjustments to the nuts to ensure cable tension and prevent twisting, coiling, or crossing of cables". (10) This AD does not adopt the "Remarks" section of EASA AD 2024-0075.
