Erickson Incorporated announced this week that the company has received FAA approval for composite main rotor blades for S-64 and CH-54 helicopters.
After many years of manufacturing metal blades, the company invested in the future of the S-64 by designing, certifying, and building composite main rotor blades that will bring many benefits. Erickson began the process of designing the new blades in 2008, working closely with the FAA and various industry partners. In 2013 they collaborated with Helicopter Transport Services (HTS), so the blades could be utilized on CH-54 rotorcraft as well.
To maintain close control of blade manufacture, Erickson built a composite manufacturing facility from scratch in 2015. After thousands of hours of design, testing, and analysis by their engineers and partners, the new composite main rotor blades are now approved by the FAA for the S-64E with an initial life that will increase as fatigue testing continues. Certification for the CH-54A is expected to follow quickly in the coming weeks, and certification for the S-64F and CH-54B should be received this summer.
In February Erickson announced the S-64F+ which will have composite main rotor blades, an enhanced cockpit and flight control system, an improved water cannon, and what the company calls a modern engine enhancing range and fuel efficiency.
Erickson, the manufacturer and operator of the S-64 Air Crane helicopter, has announced a new venture with Sikorsky, a Lockheed Martin Company. They intend to develop a new “pilot optional nighttime firefighting solution”, integrating Sikorsky’s MATRIX™ Technology into a digitally enabled fire management system never-before used in night firefighting. Erickson said it will enhance cockpit awareness and flight crew safety during day and night operations.
We have asked Erickson for more information, but it sounds like it could operate with or without a pilot on board, in other words, remotely piloted or autonomous.
Systems intelligence that will give operators the confidence to fly their large rotorcraft safely, reliably and affordably as autonomous or optionally piloted aircraft.
Air Cranes, which are sometimes referred to as helitankers, can carry up to 2,650 gallons of water.
A new Air Crane model
Erickson also announced a new production line of the legacy Air Crane helicopter, introducing the S-64F+.
The upgraded model will include composite main rotor blades, an enhanced cockpit and flight control system, an improved water cannon, and what the company calls a modern engine enhancing range and fuel efficiency.
This month Erickson Incorporated delivered another Air Crane firefighting helicopter to the Korea Forest Service (KFS), completing the delivery of the latest two-aircraft order. Another S-64 was delivered to the KFS in November. This brings the KFS operational fleet up to six S-64 Air Crane helicopters.
In 2001, KFS became the first foreign government to purchase S-64 helicopters from Erickson. The recently delivered versions have composite main rotor blades and glass cockpits. Some of the S-64 helicopters in the KFS fleet have the optional front-mounted water cannon.
Flight Global reports that the helicopter delivered in December, registration HJ9659, is a re-manufactured aircraft built by Sikorsky in 1968 that has been out of service since 1993. Erickson purchased it in November 2018.
Two S-64 helicopters have crashed while hover refilling in the last six years. One owned and operated by the KFS crashed into a lake May 9, 2013 near the Andong Dam, Kyeongbuk Province, South Korea. The two pilots died at the scene and a maintenance crew chief on board sustained serious injuries. On January 28, 2019 an Air-Crane impacted the water while assigned to a wildfire in Victoria, Australia. Three crewmembers sustained minor injuries.
Tim Crippin sent us these photos of a new S-64 Erickson Air-Crane that is being tested before it is delivered to the Korea Forest Service.
“Heard it is supposed to be delivered to them in the next week,” Tim said. “It’s temporary N- number registration is N915AC. It’s been doing plenty of flight testing the past few weeks around Southern Oregon. I heard it is the first Air-Crane to have composite rotor blades.”

These photos of helicopters refilling at the Chatsworth Lake helispot during the Saddle Ridge Fire were taken by Stonebrookphotography October 11, 2019.
The fire has burned 7,965 acres and 21 structures on the north side of Los Angeles. Strong north to northeast Santa Ana winds caused the fire to spread seven miles across Southern California, from Sylmar to Granda Hills and almost to Chatsworth. More information is at Wildfire Today.

As Australia moves into their summer and enters the traditional beginning of their bushfire season the National Aerial Firefighting Centre (NAFC) in finalizing the lineup of firefighting aircraft for the 2019-2020 season. Contracts are in place for four large privately owned large air tankers and nine large Type 1 helicopters. In addition they will have the 737 that the New South Wales Rural Fire Service purchased earlier this year.
Large Air Tankers on exclusive use contracts
Already in place and available are the NSW RFS 737 (Tanker 138) and a FieldAir/Conair Avro RJ85 (Tanker 165) both based for now on the outskirts of Sydney at Richmond, New South Wales.
In early November the mandatory availability period (MAP) begins for what will be either another 737 or a C-130Q at Richmond, provided by Coulson.
Richard Alder, the General Manager of NAFC, said, “The contract with Coulson allows for either a 737 or C-130Q. The final decision on which type will be made shortly, according to how the season is developing.”
In early to mid-December the MAPs for two other large airtankers will begin for another C-130Q and a RJ85 from Coulson and FieldAir/Conair, respectively. The scheduled base for the two aircraft is Avalon, Victoria.
Like the United States and other fire-prone areas, Australia has been experiencing wildfires during times of the year when traditionally they did not occur in large numbers. The 737 air tanker that was delivered to the NSW RFS two months ago has been busy during much of the Australian winter, completing 60 missions and delivering 237,000 gallons of water and retardant.
The nine Type 1 helicopters under exclusive use contract will include six S-64E Air-Cranes (Kestrel/Erickson) and three S-61s (Coulson). Two of the Air-Cranes will be at Bankstown, and one each at Melbourne (Essendon), Melbourne (Moorabbin), Adelaide, and Perth.
The three S-61s are to be based in Victoria at Colac, Mansfield, and Ballarat.
The base locations for all of the aircraft could change throughout the summer as the bushfire season progresses.
Single Engine Air Tankers
The recent tender process for SEATs has not yet been signed off, but Mr. Alder expects there will be about 45 on national exclusive use contracts plus another six contracted directly to state government agencies. This is 8 less than in 2018/2019.
The Sikorsky S-64E Air-Crane helicopter (N173AC) that crashed into a lake near Jericho, Victoria, Australia has been extracted. It impacted the water while assigned to a wildfire on January 28, 2019, then sank and came to rest inverted resulting in minor injuries to the three crewmembers.
Below is an excerpt from a report by Emergency Management Victoria:
The specialist salvage operation has involved the use of underwater divers surveying helicopter and undertaking initial disassembly work, including the water tank and hoses while Christine is submerged.
The complexity and scale of the operation has required months of careful planning and design. Due to the limited space, remote location of the dam and the size of the aircraft, a purpose-built lifting device has been designed to remove the Air-Crane from the dam.
The main components of the Air-Crane have been removed from the remote location by truck to a decontamination site to be sent back to America. The salvage operator will begin working on the environmental rehabilitation of the work site.

The Australian Transport Safety Bureau is investigating but has not yet released a report.
9 News has an update on the crash of an Erickson Air-Crane in Victoria, Australia on January 28, 2019. Video shows the Air-Crane on its side with a portion of the tail boom and main landing gear protruding above the water. Also the white skimming tube is visible which can be lowered as the helicopter flies near the surface of a body of water, using the same principle to refill the tank as the Be-200, Fire Boss, and CL-215/415. Drafting or skimming with the Air-Crane takes 45 seconds. It is unlikely that the aircraft was skimming when the accident occurred due to the lack of sufficient space. The Air-Crane also has a snorkel or drafting hose that is more often used for refilling while hovering over water.
Below is an excerpt from an article at ABC News Australia that was updated Monday evening, US time:
Five similar Air-Cranes — in NSW, South Australia, Western Australia and Victoria — were grounded while the crash was investigated.
Kestrel Aviation managing director Ray Cronin, whose company manages the fleet, said the ground was a “precautionary measure” while the company interviewed the crew and determined a probable cause.
He said after an initial investigation, the company and authorities had agreed that the grounding of the Aircrane fleet would be lifted.
“The Aircranes will return to service almost immediately,” Mr Cronin said.
“The crews are with the aircraft ready to rejoin the fire fight in Victoria.”
He said while he did not want to pre-empt the outcome of the Australian Transport Safety Bureau’s (ATSB) investigation, he understood “the serviceability of the Aircrane” was good at the time of the crash.

A helicopter crashed into a lake while fighting a wildfire Monday in Victoria, Australia. The Erickson Air-Crane had a crew of three, two pilots and an engineer, while it was working on the Thomson Complex Catchment fires in Gippsland. The personnel are safe after swimming to shore. Ambulance Victoria will assess the crew members. Emergency Management Victoria said the helicopter was Air-Crane HT 341, known as “Christine”.
The aircraft was one of ten aircraft working on the fire. The site of the crash, in the Yarra Ranges National Park, is about 50km (31 miles) south of Benalla.
Emergency Management Commissioner Andrew Crisp said that he was grateful that the crew are safe.
The six Air-Cranes under contract in Australia can carry more than 2,500 gallons of water or retardant. This one was N173AC, named “Christine”. Victoria also has 47 other aircraft on contract.
A total of six large fixed wing air tankers from North America have been working in Australia during their 2018-2019 summer. Tankers with their primary base at Richmond, New South Wales include a RJ85, (Tanker 166); a 737 (T-137); a C-130Q (T-134); and another RJ85 (T-165). Based at Avalon in Victoria are a C-130Q (T-131); and an RJ85 (T-163).
