Coulson Timber of Port Alberni, BC entered the aviation business in the late 1980s when it bought a Sikorsky S-61N for heli-logging, then won S-61N firefighting contracts in the Canada, the US and Australia. In 2007, Coulson bought Flying Tankers' two Martin JMR Mars flying boats and won a USFS contract in the US. When the Mars contract was cancelled, Coulson started converting C-130Q/Hs and later Boeing 737-300s into air tankers. Four Cessna 550s with sensors retired by the US Customs & Border Protection are now used to support fire ops in the US and overseas, including N552CG, ex-N4614N.
