Idaho-based MRO Western Aircraft has completed its first installation of a Skandia soundproofing system on a Pilatus PC-12. The kit received FAA STC approval in June, with a goal of reducing cabin noise, increasing passenger comfort, and improving the turboprop single’s thermal insulation properties. Western’s technicians installed aircraft skin and floor damping, as well as thermal acoustic insulation bags, overframe blankets, and carpet pads.

“The installation went flawlessly, and we were able to achieve a four-decibel sound reduction,” said Western Aircraft interior completions manager Steve Denny. “We’re excited to announce the inclusion of this installation as an available upgrade for all turboprops and Cessna Citations.”

The acoustic upgrade for the PC-12 can be performed during annual inspections without incurring any additional downtime, according to the Greenwich AeroGroup subsidiary. Western Aircraft also has experience with other Skandia products, including aircraft insulation packages and upholstery products.
