Coulson Aviation announced on August 31 that the company had secured a contract with the Bolivian Ministry of Defense to provide three Type 1 helicopters to assist the firefighters that are battling wildfires.

Shortly thereafter two of the company’s S-61 helicopters departed from California to begin their multi-day ferry to South America.

On September 4 the third ship began its journey from the airport at San Bernardino, California. Here’s what the company wrote on their Facebook page, along with these photos they posted:

The Coulson Unical CH-47D, N47CU, was loaded onto the Antonov this afternoon after a long night and morning of teardown. To fit in the airplane the blades, both the forward and rear drivetrain, and the rear pylon needed to be removed. This is a huge task to accomplish in such a short time but the team came through and will get some well deserved rest on the flight down.

Coulson has partnered with Unical Air, a new unit of the Unical Group of Companies to create a heavy lift helicopter joint venture company that will build and operate Boeing CH-47 and Sikorsky UH-60 Blackhawk aircraft for aerial firefighting and other markets. We interviewed Britt Coulson about this venture at the HAI Heli-Expo in Atlanta, March 5, 2019.

747 Supertanker ordered for wildfires in Bolivia

Air Tanker 944, the 747 Supertanker, arrived in Bolivia overnight to assist firefighters who are battling  numerous wildfires across the country. It landed at 1:37 a.m. local time Friday at Viru Viru International Airport outside the capital city of Santa Cruz de la Sierra.

It departed from Sacramento McClellan Airport and flew non-stop at 39,000 feet at 510 to 610 mph.

Air tankers do not put out vegetation fires. However under ideal conditions, especially slow to moderate wind speeds, they can retard the spread of a fire for a period of time allowing firefighters on the ground to move in and actually suppress the fire. If there are no ground forces in the area, the effect of an air tanker dropping water or fire retardant is temporary. The fire can often eventually burn through or around the area where the liquid was applied. During strong winds, the retardant is blown off target and burning embers can travel a mile downwind and start spot fires.

President Evo Morales announced on Wednesday that Bolivia has ordered the 747 Supertanker to assist firefighters battling a massive outbreak of wildfires in the Amazon basin.

The huge air tanker, identified as Tanker 944, that can carry up to 19,200 gallons (72,680 liters) of water or fire retardant is scheduled to depart from Sacramento McClellan Airport at 10:45 a.m. PDT Thursday and arrive in Viru Viru International Airport in Bolivia at about 6:42 p.m. local time.

The aircraft is being leased from Global Supertanker. According to laRazón, the company required an up front guarantee of $800,000 US dollars.

This will be the fifth formal international contract assignment for the 747. Previously it fought fires in Israel in 2010 and 2016, Mexico in 2011, and Chile in 2017.

The first drop it made on an actual fire was in Spain in July 2009 while on a world tour to introduce the aircraft to wildland firefighters. Later on that trip it dropped retardant on the Railbelt Complex in Alaska. At that time the aircraft was operated by Evergreen. Since then it has been purchased by Global Supertanker and upgraded from a 747-100 to a 747-400, but the retardant delivery system is essentially the same.
