EASA SIB NM-17-24
HAECO Cabin Solutions Seats and Seating Systems - Inspection / Replacement
Summary
The Special Airworthiness Information Bulletin SAIB: NM-17-24 is an FAA informational bulletin addressing potential weld failures in seat back frames of HAECO Cabin Solutions seats and seating systems installed on certain Transport Category Airplanes, including Airbus A330-300 and Boeing 777F models. The bulletin highlights reports of cracking in the welds that could lead to failure but does not mandate regulatory action. It provides guidance on inspection and replacement procedures to maintain compliance with passenger safety regulations.
What Changed
This bulletin introduces awareness of weld cracking issues in HAECO Cabin Solutions seat back frames and recommends annual inspections and replacement if cracks are found. It references multiple HAECO service bulletins that provide detailed inspection and repair instructions. No new regulatory mandates or airworthiness directives are issued at this time.
Why It Matters
This information is important for operators, maintenance organizations, and compliance teams to proactively identify and address potential seat structural issues that could affect passenger safety and regulatory compliance. Early detection and repair help prevent weld failures that might compromise seat integrity during operation. Following the recommended inspections supports continued airworthiness without triggering mandatory AD actions.
What To Do
Operators of affected aircraft, including Airbus A330-300 and Boeing 777F equipped with HAECO Cabin Solutions seats, should incorporate the inspection and replacement procedures outlined in the referenced HAECO service bulletins at the earliest opportunity. Annual inspections of the seat back frame welds should be performed, and any cracks found must be repaired by replacing the seat back frame. No specific compliance deadline is mandated, but prompt action is advised.
