Transwest Helicopters (1965) Ltd.

John Francis "Jack" McMahon established Transwest Helicopters (1965) Ltd. in BC in 1965.

From Jack's autobiography:
In 1964 he bought the controlling interests of an inactive Calgary Aviation company and with the other shareholders input he moved the business to the West Coast keeping the name Transwest Helicopters because of the advertising value.

It started at Vancouver International Airport as a one man, one aircraft company. Jack was 50 when he started the Company from the ground up. By 1968 he had 11 helicopters, owning 6 and chartering 5.

In 1969 he selected the new location in Burnaby. He thought the future was in rotary aircraft. At the airport he was located next to Okanagan Helicopters owned by his friend and former WWII instructor Carl Agar. Many of the men mentioned on these pages flew or knew each other during the war.

“Tim McAvoy took the company over around 1985 and had it until his death around 2001. (see article below) Transwest was sold by Tim McAvoy's wife to a European buyer and was at the Chilliwack airport until 2011, when the new owners moved to Oliver, BC

Transwest was involved in Constructing Transmission Towers, Logging, Spraying, Fire fighting,and were involved with the Federal Dept of Energy, Mines and Resources, and the BC Forest Service

In the early 1980's per Jack's bio, he established the firm at Pitt Meadows. It was about that time he ran into difficulties with the Air Transport Commission. Sounds like the same story of Spillsbury's airline! He faced 36 charges of Licensing infractions, due to some technical language in the license. None of these were safety infractions. It was due to these charges he had to give up the Company.

“My Company (Transwest) was Employee controlled and shares were made available to key employees as they joined the firm under terms of an agreement with the original shareholders of what was once a Calgary based operation.

Although the Company's main base was Vancouver, it had many designated points from which service could be obtained, together with a second base at Bella Coola, with Sandy James in charge. Permanent year round facilities were maintained at this base.”
