A wholly-owned subsidiary of Vertol Aircraft Corporation, the Canadian Company was operated as completely
independent. It was formed in February 1954,
on former RCAF airfield at Arnprior, Ontario, initially to
service and overhaul helicopters. Entered production
with the Model 42A, a modified version of the Piasecki
(Vertol) H-21 helicopter. A tandem-rotor general-purpose
helicopter, it accommodated a crew of 1/2 and 18
passengers.
