Simplex Aerospace Certifies 3,050 gallon FAS for CH-47D

Simplex Aerospace Certifies 3,050 gallon FAS for CH-47D


Simplex, April 01, 2016 - Simplex Aerospace was recently granted a Federal Aviation Administration (FAA) supplemental type certificate for a Fire Attack System (FAS) for the Columbia Helicopters CH-47D helicopter.

The system is an internal/external system, comprised of a roll-on/roll-off internal tank system connected to an external plenum.

The Simplex Aerospace Model 347 FAS is the largest helicopter firefighting system in the world.

The Model 347 is comprised of a 3,050-gallon internal tank with a 2,800-gallon water reservoir, approximately 110 gallons of water through the hookwell and 140-gallon foam concentrate reservoir that can be loaded from the helicopter’s rear loading ramp. The system also includes a 12-foot-long, 10-inch diameter hover pump, capable of refilling the tank in less than one minute.

The system includes ground fill ports so the tank can be pre-filled and ready to go at a moment’s notice. The entire contents of the FAS can be dropped in less than four seconds.

The Simplex Model 347 has the capability for the pilot to select drop patterns ranging from a single drop to multiple drops depending on the demands of the mission. An automatic emergency water drop feature is included on all Simplex Fire Attack systems in the event of an aircraft power outage.

This new Simplex FAS can be installed on the helicopter using only four bolts. Only minor modifications are required to provision for FAS installation.

The gravity-fed Fire Attack tank is installed in the aircraft cabin; then connected to a sleeve, which extends through the aircraft hookwell, joining an external plenum in the belly. Vne (never exceed speed) for the Simplex 347 FAS is 140 knots, with or without the hover pump installed.

Water drops can be made at up to 100 knots. Newly developed pilot control and display allow for U.S. Forest Service Type-one compliance. The pilot controls can be configured to show water volume, and ground refilling volume displaying gallons (or weight) on both the flight deck and ground fill input location.

“This new and innovative CH-47D FAS for Columbia Helicopters is the largest helicopter FAS in the world today,” said Mark Zimmerman, Simplex president and CEO. “With total water evacuation in under four seconds, it is the most cost-effective FAS available to operators around the world.”

Zimmerman went on to say, “the system was developed for installation with very minimal aircraft provisioning required, making installation fast and cost effective.”

Zimmerman further stated that the system has an excellent drop pattern. He stated that the “new system is like the Kamov Ka-32, and the Firehawk systems, with an exceptional drop pattern.”

Simplex Aerospace Fire Attack systems are regarded worldwide as a critical tool in aerial firefighting missions. The systems are trusted by original equipment manufacturers, private operators and government firefighting agencies for their durability, reliability, efficiency and safety.

Simplex Aerospace is committed to producing the most advanced certified aerial firefighting systems on the market with the features and quality customers demand.

Founded in 1946, Simplex has built a reputation as the leader in design, manufacturing, and certification of aerial application systems and mission equipment for helicopters. Simplex maintains its industry leadership by incorporating the latest technology in designing and manufacturing systems from high-strength, low-weight composite materials to produce reliable and cost-effective systems for firefighting, agriculture, utilities maintenance and other aerial applications.
