LightRock continues his occasional series on helicopters and firefighting:
In the wake of last week’s fatal crash involving a firefighting helicopter in Northern California, it is perhaps worth learning a little more about the model of helicopter involved and the company that owned and operated the ill-fated aircraft.
Back in October we reported on how an Oregon based company – Erickson Air Crane – had built their business around the Sikorsky H-54 Skycrane and had morphed the original Sikorsky design into a modern and highly capable heavy lift/firefighting helicopter. That report can be found HERE.
The helicopter involved in last week’s accident was a Sikorsky S-61N helicopter. The S-61 is the civilian version of the H-3 Sea King. Sikorsky initially developed the H-3 for the U.S. Navy in the late 1950’s and it initially entered the Navy fleet in 1961.

During its service life with the Navy, it performed a variety of roles including anti-submarine warfare and search and rescue, as well as being used routinely to transport personnel and cargo. The H-3 served with the USN until early 2006; however, it is still in use in the militaries of Japan, Italy and the U.K., among others. The H-3 also has retained one mission for the U.S. military: Marine Helicopter Squadron HMX-1 continues to use the H-3 as their primary helicopter to transport the President of the United States. The H-3 was and is considered a very stable, smooth and flexible design and, unlike many helicopters, its passenger/cargo area has some headroom, which is one of the reasons that this design has continued to endure in the VIP/Presidential transport role even though many newer helicopter designs have been introduced over the years.
The civilian S-61 was developed shortly after the original H-3. It is very similar to the H-3 except that the fuselage is somewhat longer, optimizing the design for use in transporting personnel and cargo. First introduced to the market in the early 1960’s, the S-61 has continued to serve in a number of commercial roles ever since.

Among the operators of the S-61 is Carson Helicopters. Carson was the operator of the aircraft involved in last week’s accident. Carson has been in business since 1963 and has offices in Pennsylvania and Oregon, operating their helicopters worldwide in a variety of roles. The company’s growth has been centered on the S-61, continuing to modernize and enhance the initial Sikorsky design. Carson has made over 20 FAA approved enhancements and upgrades to the S-61, recently and most notably developing a composite main rotor system that the military is now planning on retrofitting onto the helicopters it even uses for Presidential transport. The composite rotor system enhances payload, speed and range. The company’s website also indicates that a composite tail rotor and a digital “glass” cockpit design are in the pipeline. Carson’s S-61 design optimized for firefighting is known as the Fire King.

Whereas the Erickson Air-Crane we referred to above is optimized for dropping large quantities of water/retardant, the Fire King is intended to be a more multi-mission firefighting aircraft. In addition to a pilot/co-pilot, the Fire King can carry up to 15 passengers and is equipped to support stokes/rescue basket operations, as well as rappelling. It can sling a load of up to 11,000 pounds and is equipped with a 1,000-gallon belly tank for water/retardant. Capable of cruising at 131 knots (about 150 MPH) and travel approximately 500 miles, the Fire King possesses both speed and range.
Without question, last week’s crash has stuck a blow to Carson, as well as the firefighting and rotary-wing aviation communities. However, as significant wildfires become an increasingly common occurrence, we are sure to see Fire Kings continuing to work these fires from above.

Reducing Fuel Consumption
2 commentsLightRock addresses the diesel fuel budget:
In the current economic environment and with diesel fuel prices in the $5.00/gal range (a 67% increase in 12 months), can fire and rescue departments continue to afford to do business as usual?
According to a June 18th article in the Wall Street Journal Online HERE, it appears that the answer is “No”. Here are a few questions worth pondering:
