What the NTSB found accidents and incidents since 2008 in which the NTSB's findings named this system
In 125 cases since 2008 the NTSB named cabin, seats and restraints as a cause (35 of them) or a contributing factor; 51 of those were fatal accidents. The part most often named is the equipment/furnishings › flight compartment equipment. Among model families, the Cessna 172 Skyhawk appears most often. A failure report (above) is a part that failed and was fixed; an NTSB finding is a part that the investigators decided helped cause an accident. The two measure different things, and both are here.
