Ramm Aerospace won EASA approval for its Bell 206/407 frameless seat cushions, whose form “provides improved overall comfort and added lumbar support,” while reducing maintenance costs, said the company. The Helifab STC eliminates the frame for all forward-facing passenger seats. The STC will be available for all seating positions in the near future, Quebec-based Ramm said. The 206/407 frameless seat cushion covers are available in Naugahyde or Ultraleather in various colors.
