FAA advisory raises concerns over general aviation seatbelt and restraint system failures linked to serious injuries and fatalities.

The FAA has issued a Special Airworthiness Information Bulletin (SAIB) highlighting safety concerns with certain general aviation seatbelt and torso restraint systems following multiple injury-related accidents.
While the bulletin is classified as “information only” and does not mandate action, it raises important questions about whether existing restraint systems are meeting current safety expectations.
“At this time, the airworthiness concern is not an unsafe condition that would warrant an Airworthiness Directive (AD),” the FAA noted.
The advisory is based on findings from the National Transportation Safety Board (NTSB), which identified several incidents where restraint systems were ineffective, leading to serious injuries and, in some cases, fatalities.
Evidence from Accident Investigations
One of the cases referenced occurred in September 2012, when an Aeronca 7AC lost control during take-off and crashed.
The pilot sustained serious injuries, while the passenger was fatally injured. Investigators cited ineffective restraint systems as a contributing factor.
Further NTSB analysis revealed that in some cases, four-point restraint systems failed under loads below those required by current Technical Standard Orders (TSOs).
A review of the NTSB public docket identified at least 15 additional accidents where injuries were linked to full or partial restraint system failure. Many of these systems were found not to meet updated TSO performance standards.
FAA Recommendations
Although the bulletin does not impose mandatory requirements, the FAA recommends that owners and operators of general aviation aircraft:
Verify that installed restraint systems meet current TSO performance standards
Inspect seat-belt and harness systems for wear, degradation, or improper installation
Consider upgrading older restraint systems that may not meet modern safety requirements
