I have seen some video previously of this contraption used for trimming trees from a helicopter, but this video from YouTube is better than some. Haverfield Aviation uses the 20-foot long side-trimming saw to trim trees along powerline and gas line right-of-ways. They said it is powered by a compact fuel injected engine and is able to side-trim a 20′ path of vegetation an average of three miles per day on both sides.
It seems that the pilot, in addition to having to have cojones of steel flying adjacent to a power line, would have to have exceptional depth perception to be sure the saw does not drag on the ground, since hitting dirt or especially a rock, would instantly dull the blade.
I’m not sure if this would be feasible to be used on fires if it can only side-trim the branches on trees. Maybe it could widen an established fuel break by 10 to 15 feet on each side.
In this first video you will meet a CAL FIRE helicopter pilot whose previous job was flying the President around in Marine One.
The bonus video below shows a very skilled pilot in Oregon quickly, very quickly, ferrying external loads of Christmas trees from the farm to trucks. It is Pilot Dan Clark flying a Northwest Helicopters, LLC 206B3 Jetranger in November of 2008.
The videos can also be seen on YouTube here and here.

The American Helicopter Services & Aerial Firefighting Association (AHSAFA) has issued a press release about the current state of contracted aerial firefighting services for the federal government.
WASHINGTON, Nov. 15, 2013 — On the eve of its 2014 Annual Meeting in Boise, Idaho, on November 20, the American Helicopter Services & Aerial Firefighting Association (AHSAFA) has cited some progress over the past year toward airtanker fleet modernization, along with on-going opposition to any increased role for government in the aerial firefighting business.
“After years of discussions between AHSAFA, US Forest Service (USFS) officials, and Congress, multi-year, operating contracts—worth $261 million—were awarded last spring by the USFS to five companies for seven next-generation large airtankers, to be available for the 2013 fire season,” said AHSAFA Executive Director Tom Eversole. “The USFS has said there is a need for as many as 26 modern large airtankers within the next five years. We consider the contract awards to be a major step toward the replacement of the current large airtanker fleet, consisting of seven to eight Cold War Era military surplus aircraft. All indications are that the USFS will not contract for these legacy aircraft beyond the current contract period, which ends in 2018.” Continue reading “Trade organization issues press release about the state of fire aviation”
Helicopters in the Yellowstone area made at least two short haul rescues in August, both of them with ASTAR B3 ships.
The first occurred on August 17 in Mount Rainier National Park in Washington. The helicopter from Yellowstone National Park had been assigned to the general area for fire and rescue support working out of Wenatchee when a climber had a medical problem at the 12,000′ level on Mount Rainier at Disapointment Cleaver. The Mount Rainier rangers knew the Yellowstone helicopter was in the area and requested it to respond after they evaluated the condition of the climber and considered the rescue alternatives.
The other happened on August 27 after a snag struck a Chena Hotshot crew member while assigned to the Kelley fire on the Sawtooth National Forest in central Idaho. The rescue was performed by a Jackson, Wyoming Teton Interagency helicopter while the ship was assigned to the fire. The National Park Service describes this rescue:
“…Immediately after the accident, the Chena superintendent requested a medical evacuation, prompting air attack to request an air ambulance and a hoist-capable helicopter. Hearing the radio traffic, a Teton Interagency Helitack crew member assigned to the helibase notified air attack that the crew and Helicopter N26HX, which was conducting water drops from a dip site near Helibase, were short-haul capable. Short-haul is a rescue technique where an individual is suspended below the helicopter on a 100 to 200 foot rope. This method allows a rescuer more direct access to an injured party, and it is often used in national parks like Grand Teton National Park in the Teton Range where conditions make it difficult to land a helicopter in the steep and rocky terrain. Patients are typically flown out via short-haul with a ranger attending to them below the helicopter.
Operations diverted the helicopter from a water bucket mission, and the crew began preparing for a short-haul. Pilot Chris Templeton and short-haul spotter Garth Wagner flew a reconnaissance mission. Tasks included locating a suitable insertion spot, conducting environmental and power checks, and determining that a short-haul mission was the appropriate tool. Based on the recon flight, the crew completed a short-haul and Green-Amber-Red (GAR) risk assessment, then readied for the mission. They configured the helicopter by removing the doors, attaching a “three-ring” backup to the cargo hook, and inspecting and attaching a 150-foot-long short haul rope to the cargo hook. They also checked the harnesses for the short-hauler and spotter, as well as the communication systems. A litter was prepared with a harness and attachment points.
While the helitack crew was preparing helicopter N26HX for short-haul, another helicopter delivered medical gear to the site of the injured firefighter. An EMT on the Chena Hotshots and other crew members prepared the patient for transport. The helicopter inserted short-hauler Ron Johnson, whose normal job is as a Jenny Lake climbing ranger at Grand Teton National Park, with a litter and line gear into the extraction site. Rescuers transported the patient on a spine board the 150 feet to the extraction site. Because the patient was already packaged, the helicopter extracted him and the short-hauler about 15 minutes after inserting Johnson on site. They were flown back to helibase where a team of Teton Helitack members caught the patient and litter and transferred him to an awaiting life-flight helicopter.
During the week before the successful rescue mission, the Teton Helitack crew flew nearly three hours of short-haul training in typical terrain for pilot proficiency. Such proficiency training is required every 28 days, and in this case, the training was also essential in preparing the helitack crew to receive the patient and litter at helibase.
Using the short-haul method is relatively new to wildland fire, but is one of the preferred methods of rescue in the rugged terrain of several national parks, including Grand Teton, Yellowstone, Yosemite, Zion and Grand Canyon. The Yosemite Helitack crew performed a successful rescue earlier in August on the Green Ridge fire on the Deschutes National Forest.”
The bushfire season has historically started in late November or early December and lasted through February, but now that we have warmer and more extreme weather across the globe fire managers in Australia and around the world are having to adapt.
Most of the firefighting aircraft in Australia are privately owned and work under contracts for the government. The National Aerial Firefighting Centre (NAFC) coordinates the procurement of the aircraft on behalf of the States and Territories.
Richard Alder, the General Manager of the NAFC, told Fire Aviation that about one third of the 75 contracted aircraft have started work already and the majority will be on by early to mid-December, depending how the fire season develops in the south part of the country. As the summer temperatures increase, the down under fire season moves from north to south. The 75 aircraft includes helicopters, Single Engine Air Tankers (SEATs), and fixed wing aircraft that are used for reconnaissance and other purposes.
During last year’s 2012-2013 fire season, NAFC had the following on contract:
14 SEATs (Air Tractor AT 802 and AT 602)
3 Bell 206-L
2 Bell 205
5 Bell 212
2 Bell 214-B
5 Erickson S 64 Air-Crane
12 Eurocopter AS 350, 355, and 365
2 Kawasaki BK 117-B2
4 Sikorsky S 61-N
This season, 2013-2014, in addition to the smaller helicopters, Mr. Alder said they will have:
23 SEATs, which includes one water-scooping FireBoss. (All are on exclusive use, three-year contracts with options to extend to five years.)
6 Erickson S 64 Air-Cranes (from Kestral Aviation via Erickson)
2 Sikorsky S 61-N (from Coulson Aircrane Australia, a subsidiary of Coulson Aircrane in Canada)
10 Bell 214-B, which the NAFC considers a Type 1 helicopter (from McDermontt Aviation)
Other aircraft, including 30 SEATs, are available on call when needed contracts.
There are no air tankers larger than SEATs working in Australia, in spite of a request for proposals that NAFC issued in November, 2012. They advertised it at the time via Twitter:
NAFC has published a Request for Proposals for large fixed wing airtankers for 2013 onward. Visit http://t.co/V1Ovp4Vt for further info.
That RFP indicated their intention to contract not only for various types of helicopters, but also for water-scooping, large, and very large air tankers. We asked Mr. Alder what became of the effort to procure the larger aircraft. He responded:
The RFP is a component of a major project we have running to closely examine the applicability of larger fixed wing airtankers in the Australian situation. The project is ongoing and we are continuing to (actively!) gather and analyse data and related information on these capabilities (and are particularly grateful to our colleagues in the US for sharing their experiences over the recent season).
