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.
“We’re developing the STC at the request of a number of our customers,” said Colleen Back, director of sales and marketing for the Grand Junction, Colo.-based company. “Many operators are not aware that these standards apply to the foam and covering on the seats–not just the seat framework. Even changing the upholstery on a seat requires compliance with dynamic test criteria,” she added.
West Star has contracted with Aviation Consulting and Engineering Solutions of Wichita, Kan., to complete the engineering and certification phase of the CitationJet seat design. The company expected to earn the STC by the end of October.
West Star also announced it has completed the installation of its 100th Learjet 30-series RVSM solution. Of those, 87 were completed at the company’s Grand Junction facility. The remaining 13 were completed at authorized installation facilities in various locations across the country. According to the FAA RVSM approval database, West Star has completed close to 50 percent of the approved Learjet 35/36 RVSM modifications to date.
The company reports that installation slots for the West Star RVSM modification are booked through the end of this month, and it is currently scheduling installations for January and February. (The deadline for compliance is January 20.) Learjet 30-series operators are encouraged to schedule their RVSM upgrades now to avoid equipment backorders. If operators schedule the RVSM modification far enough in advance, West Star’s turn time is approximately two weeks.
