The CH-112 Helicopter
The CH-112 was a three place light piston engined helicopter that was in Canadian service from 1961 to 1972. The aircraft was manufactured by Hiller Aircraft Co in Palo Alto CA as a commercial model UH12E. It was similar to the US Army OH23G “Raven”. The name “Nomad” was assigned to this helicopter but the name was never in common usage.
The initial purchase of 25 aircraft with serial numbers 10261 to 10285 was supplemented by two further aircraft, 286 and 287 in 1964. Three helicopters, (261, 262 and 263) were painted in RCAF trainer yellow paint scheme with the last three numbers and RCAF in black on the tail boom. These aircraft were equipped with an artificial horizon and an ADF radio as well as the standard 10 channel ICA67 VHF radio. The remainder were painted in high gloss olive drab with the three numbers and ARMY in white on the tail boom and a yellow warning band in front of the tail rotor. This title was changed to CDN ARMY with the national flag on the baggage compartment in 1963. These Army helicopters had the VHF radio and the ARC44 FM radio for tactical communications. This radio had a built in aural homing function using the twin dipole antennas mounted on the tail boom.
The helicopters were all delivered to the Canadian Joint Aviation Training Centre (CJATC) at Rivers MB in 1961 and were used by the RCAF Basic Helicopter Training Unit (BHTU) and the Army Aviation Tactical Training School (AATTS). These units were became 4 Flying Training School (4 FTS) in 1968 after unification and as 3 FTS after being relocated to CFB Portage. One CH-112 (285) was assigned to 1 Transport Helicopter Platoon (1THP) RCASC to provide a liaison function for this CH113 Cargo helicopter unit. Nine aircraft were assigned to operational roles with Canada’s NATO Brigade Group in 1962. Seven (275 to 281) to the Royal Canadian Armoured Corps (RCAC) Helicopter Troop, 283 to 1 Transport Company RCASC and 282 to HQ 4th Cdn Inf Bde Gp (4CIBG) Liaison Flight.
The RCAC helicopter troop became the 4th troop of the Brigade Reconnaissance Squadron which was equipped with Ferret scout cars and later, the M113A Lynx tracked recce vehicle. This squadron was provided by the individual armoured regiments in rotation. The troop was part of 8th Canadian Hussars in 1962, followed by the Fort Garry Horse, 8th Hussars again and subsequently by “C” Squadron of the Royal Canadian Dragoons. The troop was absorbed into 444 Tactical Helicopter Squadron in Oct 1972.
The aircraft assigned to the Brigade were repainted in a NATO gray/green camouflage pattern with CDN ARMY in black letters in 1963. After unification the markings were changed to be Canadian Armed Forces. All the Canadian Forces Europe (CFE) CH-112’s were sold to UK agent in 1972 when the CH136 Kiowa came into service.
