FAA SPECIAL AIRWORTHINESS
Aviation Safety INFORMATION BULLETIN
SAIB: NM-17-24
SUBJ: Equipment/Furnishings Date: August 28, 2017
This is information only. Recommendations aren’t mandatory.
Introduction
This Special Airworthiness Information Bulletin is to advise owners and operators, and the original
equipment manufacturers of certain Transport Category Airplanes having HAECO Cabin
Solutions seats and seating systems of the potential for failure of the weld in the seat back frame.
At this time, the airworthiness concern is not an unsafe condition that would warrant airworthiness
directive (AD) action under Title 14 of the Code of Federal Regulations (14 CFR) part 39.
Background
The FAA has received numerous reports of cracking found from the seat back frame to the cross tube
weld of the seating system. This cracking can propagate to a full weld failure. While the risk of
injuries is low, the weld failure, if not corrected, could impact compliance with certain passenger
safety regulations.
HAECO Cabin Solutions has issued the following service information, which provides procedures for
inspecting the seats and seating systems annually, and replacing the seat back frame if any crack is
found.
