A CRJ-200 flight and cabin crews discovered multiple passenger seats with seat bottoms that were not securely attached to the seat structure due to insufficient adherence to the underlying support webbing. The reporter suggested this was a fleetwide problem rather than unique to the aircraft involved.

Narrative

After the flight we assisted the Flight Attendant in cleaning up the cabin prior to going to our next aircraft. We discovered we constantly had to reset the seat cushions as they were coming out of place on a majority of the seats. We pulled many of the cushions up and found that the webbing that supports the seat cushions was hanging slack and not supporting the cushions until they were squished down into the webbing and causing them to come out of place in the seat. In one case we found that the seat webbing had torn. We wrote up a discrepancy for that seat as it had obvious damage.Our concern is that the seats would not provide the required crash protection since the webbing on the seat is worn. This condition most likely exists on many aircraft. Maintenance should review the age and condition of all passenger seats and the cushions and determine if they meet crash worthiness requirements. They should replace worn seat cushions and/or rebuild seats as needed to ensure crash protection for our passengers.
