New South Wales’ new 737 makes its first drop on a fire

This is the second 737 to be fully converted into an air tanker by Coulson Aviation

Tanker 138, the 737 air tanker that the New South Wales Rural Fire Service (NSW RFS) purchased from Coulson Aviation, was delivered a couple of weeks ago and it just made its first ever drop on a wildfire.

The NSW government first announced the acquisition May 15, 2019 saying it was part of a $26.3 million investment to enhance the aerial firefighting capacity in the Australian State.

“This type of aircraft can deliver 15,000 liters (3,960 gallons) of fire suppressants, transport about 70 firefighters and operate from a number of regional airports,” Minister for Police and Emergency Services David Elliott said.

NSW RFS Acting Commissioner Rob Rogers said the Service had evaluated a number of different Large and Very Large Air Tankers over recent fire seasons and had settled on the 737 as the preferred option, operated by Canadian company Coulson Aviation.

NSW will purchase one Boeing 737 Fireliner and two Lead/Intelligence Aircraft. They are accompanied by a ten-year operational contract where Coulson will provide all flight and maintenance personal. The 737 is scheduled to be delivered in July of this year.

Britt Coulson, Vice President of Coulson Aircrane, said the company will supply two Cessna Citation V/560s to serve as lead/intelligence aircraft for NSW RFS.

This was the second 737-300 air tanker converted by Coulson Aviation. The company purchased six in 2017 in order to modify them into 4,000-gallon “Fireliners” that can also carry up to 70 passengers when it’s not hauling retardant. Mr. Coulson said they saw an opportunity when Southwest Airlines made a decision to replace their 737-300’s with the new 737-Max. Since the FAA only allows Southwest pilots to fly two of the 737’s with the same rating, the airline opted to sell the 737-300’s even though they have a relatively low number of hours in the sky. (I wonder if Southwest is regretting getting rid of the 737-300s now that their new 737-Max airliners are all grounded.)

New South Wales purchases 737 air tanker

NSW will also buy two Cessna Citation Lead/Intelligence Aircraft

The New South Wales Rural Fire Service obviously was satisfied with the performance of a Boeing 737-300 that was under contract during their 2018-2019 summer fire season since they just signed a contract to purchase one of the converted airliners.

The NSW government announced the acquisition May 15, 2019 saying it is part of a $26.3 million investment to enhance the aerial firefighting capacity in the Australian State.

“This type of aircraft can deliver 15,000 liters (3,960 gallons) of fire suppressants, transport about 70 firefighters and operate from a number of regional airports,” Minister for Police and Emergency Services David Elliott said.

NSW will purchase one Boeing 737 Fireliner and two Cessna Citation V Lead/Intelligence Aircraft. They are accompanied by a ten-year operational contract where Coulson will provide all flight and maintenance personal. The 737 is scheduled to be delivered in July of this year.

Britt Coulson, Vice President of Coulson Aircrane, said the company is acquiring two Cessna Citation V/560 aircraft now.

“They will be equipped with brand new Garmin EFIS cockpits complete with Synthetic Vision and linescan/gimbal systems designed and integrated by us”, Mr. Coulson said. “These aircraft are required to be multi-role so like the B737 Fireliner, we will integrate the tech package to not limit the airplane’s performance or ability to move passengers. We saw great success with the Citation Jet/525 that was operated in the USA and wanted to build on that program with a slightly larger, more capable airframe. With the B737 Fireliner being the fastest Large Airtanker, it really needs the fastest support platform.”

Britt said a technician in the back of the Citation will operate the video equipment and other sensors. Their goal is to retain seven passenger seats.

The NSW contracting office works much more quickly than what we have been seeing in recent years from their U.S. Forest Service counterparts. The initiative to purchase a large air tanker was announced in mid-December 2018 and now five months later the procurement has been consummated, with delivery of the air tankers expected in another two months. It has taken multiple years in some cases to contract for air tanker services in the Forest Service that are guaranteed for only one year. The NSW contract for operation and maintenance is for ten years. The Canadian province of Manitoba awarded a 10-year contract for the management, maintenance, and operation of their fleet of seven water-scooping air tankers (four CL-415s and three CL-215s), supported by three Twin Commander “bird-dog” aircraft.

Coulson Aviation CEO Wayne Coulson said he looked forward to being able to work with the RFS on this new venture and would be expanding its NSW base in the coming months. The company will be looking to hire Australian pilots and ground crew.

In recent years NSW and Victoria have hired large air tankers, primarily from Canada, for their summer bushfire season. During the 2018-2019 summer the two governments employed six, including one 737, two C-130s, and three RJ85s. They also brought in six Erickson Aircranes, as well as other heavy helicopters. The last of the contracted Large Air Tankers left NSW to return to the United States late last week.

Coulson Aviation began their 737 project in 2017 when they purchased six 737-300’s from Southwest Airlines which had decided to replace them with the new 737-Max. Since the FAA only allows Southwest pilots to fly two  737’s with the same rating, the airline opted to sell the 737-300’s even though they had a relatively low number of hours in the sky. With the 737-MAX being grounded after two crashes, Southwest may be regretting the decision to part with the aircraft.

The 737 air tanker was designed as a multi-use aircraft with the ability to haul passengers. In 2017 Britt Coulson said “With a full retardant load and 4.5 hours of fuel we are so far under max gross weight we are going to leave the full interior and galleys in even when just in airtanker mode.”

This is not a video, but a screengrab from a video of Air Tanker 137, a 737, dropping on the Bruxner Highway Fire (Tenterfield LGA) in New South Wales, Australia, February, 2019. Usually it is not obvious when an air tankers drops simultaneously from more than one tank, but on the 737 the two tanks are not adjacent to each other, making it possible to see the separation when the drop begins. The video can be seen here.

The 737 made its first drop on an active fire November 22, 2018 on a bushfire in New South Wales.

In these photos the aircraft was dropping gel, which clings to the vegetation and retains the moisture.

Coulson completed the conversion of the 737 a few months ago and it is now working on a contract with the New South Wales Rural Fire Service during their summer. Nicknamed “Gaia”, it arrived at Richmond RAAF Base near Sydney November 11 after a multi-day trip across the equator. It will be primarily based at the RAAF Base along with three other large air tankers from North America — a C-130Q (T-134), and two RJ85s (T-165 and T-166). Two other large air tankers will be based in Victoria at Avalon Airport in Melbourne, a C-130Q (T-131), and an RJ85 (T-163).

Going by the coordinates on the images, the fire T-137 dropped on was very close to the Kurri Kurri Hospital southwest of Heddon Greta. The NSW RFS reported at 8:14 p.m. local time on November 22 that firefighters assisted by aircraft had slowed the spread of the fire. They estimated it had burned 61 hectares (151 acres).

Today the New South Wales Rural Fire Service introduced to the media the fourth large air tanker that will be assisting ground-based firefighters in NSW and other Australian states during their bushfire season that is well underway.

The conversion of the Boeing 737 airliner into what Coulson calls a “Fireliner” was just completed a few months ago and has not yet dropped on a live fire. Tanker 137, nicknamed “Gaia”, arrived at Richmond RAAF Base near Sydney November 11 after a multi-day trip across the equator. It will be primarily based at the RAAF Base along with three other large air tankers from North America — a C-130Q (T-134), and two RJ85s (T-165 and T-166). Two other large air tankers will be based in Victoria at Avalon Airport in Melbourne, a C-130Q (T-131), and an RJ85 (T-163).

One of the speakers at the welcoming ceremony said one feature that separates the 737 from the other air tankers is that when it is not carrying 4,000 gallons of fire retardant, it can transport up to 70 firefighters or other passengers.

The NSW Minister for Police and Emergency Services, Troy Grant, announced that $23.6 million will be available for a large air tanker to be permanently based in NWS. This will be a first for the state and the country.

Aussies set the summer lineup for their firefighting aircraft

During the coming bushfire season they will have access to six large air tankers and scores of SEATs and helicopters

Australia’s National Aerial Firefighting Centre (NAFC) has virtually settled on its lineup of the country’s firefighting aircraft for the 2018-2019 bushfire season which is getting underway. It was just a few years ago that they had no large air tankers, but this season they will have six privately owned large air tankers on contract, including three RJ85s, two C-130Qs, and one 737.

Large air tankers:

  • RJ85, T-165  (Aeroflite/Conair via FieldAir) based in Sydney (Richmond)  –  already in place;
  • B-737,  T-137 (Coulson)  based in Sydney (Richmond) – subject to  regulatory approvals;
  • RJ85, T-166  (Aeroflite/Conair via FieldAir) based in Sydney (Richmond)/Dubbo;
  • C-130Q, T-134 (Coulson) based in Sydney (Richmond) – already in place.  (This is an “extra” for the 2018-19 season only, considering the predicted above-normal potential of the fire season on the east coast of Australia);
  • RJ85, T-163  (Aeroflite/Conair via FieldAir) based in Melbourne (Avalon);
  • C-130Q, T-131 (Coulson) based in Melbourne (Avalon)

Coulson’s recently converted 737 just went through its first flight tests for the U.S. Interagency Airtanker Board in September, dropping retardant into a grid of hundreds of cups on the ground. For it to be used in Australia it must first receive their regulatory approvals.

Single Engine Air Tankers

In addition, NAFC will have 51 Single Engine Air Tankers (SEATs) on contract across the country,  including 2 amphibious water-scooping Fire Bosses. Another 8 SEATs have been contracted directly by State agencies. The SEATs can also be supplemented by other aircraft on Call When Needed (CWN) arrangements if required.

Helicopters

There will be 77 Helicopters of all types for a variety of roles across the country.  This includes six Erickson S-64E Aircranes, as well as five Type 2 /Type 3 helicopters that will be specially equipped for intelligence gathering, with gimbaled sensors and on-board image processing, mapping, and transmission gear.

Night flying helicopters

Near the end of the 2017-2018 bushfire season the Aussies experimented with dropping water from helicopters at night in Victoria.

This season one Type 1 helicopter (a Coulson S-61) based at Ballarat, Victoria and one Type 2  helicopter (a Kestrel Aviation Bell 412) based at Mangalore, Victoria will have a Night Vision Imaging Systems or Night Vision Goggles (NVIS/NVG) for water dropping. Several other Type 2 and Type 3  helicopters based in Victoria and New South Wales will be capable of NVIS mapping, reconnaissance, supervision and aerial ignition.

“We aim to continue and extend the helicopter NVIS firebombing trial in Victoria, operationalizing the learnings from the Victorian trial earlier this year, but it will be in small, careful steps” Richard Alder, General Manager of NAFC said. “At this stage”, he continued, “it is anticipated that night firebombing will only occur on fires where the aircraft crew has operated during the day – so at this stage there won’t be any initial attack at night.”

Mr. Alder said they may experiment toward the end of the 2018/2019 bushfire season with a fixed wing large airtanker (the C-130Q, T-131) using NVIS/NVG, but there is much work still to be done to design the trial and obtain the necessary regulatory approvals.

Grid testing for the 737

Coulson Aviation intends for the 737 to be able to haul 4,000 gallons of retardant, or passengers

Coulson Aviation posted these photos September 3, 2018 of one of their recently converted 737-300’s, Tanker 137, as it was undergoing grid testing in Lancaster, California.

The process involves dropping retardant over a grid of thousands of cups intended to measure the volume and consistency of the pattern when it hits the ground. The Interagency AirTanker Board requires passing this and other certifications before an aircraft can be “carded” as a federal air tanker, which makes it eligible for a contract to fight fires.

Some air tankers are required to make 20 to 25 drops over several days at the test. Firefighting hand crews are usually hired or borrowed to retrieve the cups after each drop. It is a very expensive process. The last time we checked the price of retardant was $2.50 to $3.00 a gallon, depending on which air tanker base it is delivered to.

They intend for it to be able to haul 4,000 gallons of retardant, or passengers. Last year Britt Coulson said, “With a full retardant load and 4.5 hours of fuel we are so far under max gross weight we are going to leave the full interior and galleys in even when just in airtanker mode.”

The company purchased six 737-300’s from Southwest Airlines.

The first drops from the 737 air tanker

On July 13 the 737 that Coulson Aviation has been converting into an air tanker made its first drops. In this case it was a series of water drops by Tanker 137 while flying out of San Bernardino, California.

Britt Coulson said, “The 4,000 USG RADS-XXL/2 performed perfectly as did the airplane. Our flight crew couldn’t have been happier with the handling characteristics and our split tank worked as designed with no CG shift during the drop.”

Next week they will finish flight testing with the FAA, and will soon begin static tests of the tank system. They are working with the Forest Service to schedule the grid test.

Mr. Coulson expects Tanker 137 will be ready to fight fire in August.
