West Star to develop Citation 525 seat STC
West Star Aviation is developing “16g” cockpit, cabin and lavatory seats for the Cessna CitationJet line.

West Star Aviation is developing “16g” cockpit, cabin and lavatory seats for the Cessna CitationJet line. The seats meet the emergency landing dynamic test requirements of FAR 23.562, which prescribes a 16g tolerance.

FAA regulations require that the aircraft seat/restraint systems protect the occupants during emergency landings under specific testing conditions. If an aircraft was originally type certified with an interior configuration meeting the dynamic test requirements of FAR 23.562, any alterations to that configuration–including basic re-upholstering–must also meet these criteria. Interior refurbishment on these aircraft may be performed only by the manufacturer or at a facility holding supplemental type certificates (STCs) demonstrating that the alterations comply with FAR 23.562 dynamic test standards.
