The Canadair CL-41, designated the CT-114 "Tutor" in
RCAFand later unified Canadian Forcesuse, is a jet trainer aircraft designed and built by Canadair. Ordered in September 1961, the aircraft went on to serve as the Canadian Forces primary jet trainer until 2000, when it was replaced by the CT-155 Hawk and CT-156 Harvard II. The CL-41G supplied to Malaysia was built as a ground-attack aircraft.
The Tutor is perhaps best recognized as the aircraft used by the
Design and development
The CL-41 design was the product of the Canadair Preliminary Design department led by Roy Dishlevoy, Joe Knapp, Fred Philips, Bob Ross and Bob Werett. [ Dishlevoy 2005, p. 8-10. ] The design incorporated a turbojet-powered, low wing
monoplanewith a tricycle undercarriage and a T-type tail assembly. The flying controls are manual with spring tabs. The cabin, closed by a bubble-type canopy, can be pressurised to a differential of 3 psi (20 kPa), the equivalent of about 2,000 m of altitude. It was designed to be a side-by-side trainer for providing elementary jet flight training and other training to an advanced level. The prototype first flew on 13 September1960.
One critical area of design was the positioning of the fin. The CL-41 was intended to demonstrate spin recovery. If the fin is too far forward, spin can not be initiated, but if it is too far aft, recovery becomes impossible. Model tests were done to find the optimum position. The original Tutor wind-tunnel model had a
cruciformtail, which was revised to the T-tail design by removing the portion above the horizontal stabilizer.
In September 1961 the Canadian government ordered 190 examples of the production variant, CL-41A for the RCAF as the CT-114 "Tutor". For over 30 years, the Tutor, known affectionately as "Toot" in RCAF and CF use, served as a primary trainer. In 1976, the
Canadian Forcesmodified 113 survivors with provision for two external fuel tanks (drop tanks) and upgraded avionics.
The company also developed an armament training and light attack variant, the CL-41G, with an uprated engine and underwing hard points to allow the carriage of external stores (up to 4,000lb (1814 kg) of weapons) and drop tanks. In March 1966, the
Royal Malaysian Air Forceordered 20 (serials M-22-01 to M22-11) CL-41G-5 Tebuan (which means "Wasp" in the Malay language) aircraft as "Counterinsurgency" (COIN) aircraft . The Tebuan entered service in Malaysiain 1967, serving for over 20 years, before being phased out in June 1986 and replaced by the Aermacchi MB-339A.
One other variant was developed, the CL-41R which was fitted with an F-104 Starfighter nose as a proposed electronic systems trainer for future RCAF CF-104 pilots. The R model never went into production.
In 1967, ten Tutors were modified for use as a formation aerobatic aircraft by the RCAF (and later the unified
Canadian Forces) display team, the " Golden Centennaires" to celebrate Canada's Centennial year. The display team was later disbanded but, a few years later, 431 Air Demonstration Squadron was reactivated as the nine-aircraft team, the " Snowbirds," who continue to perform at air shows and special events including the annual flypaston Canada Dayover the capital city, Ottawa.
Modifications for the Snowbirds include: a smoke generating system, a unique paint scheme for added crowd appeal, and a highly tuned engine to enhance engine response in low level flying.
;CL-41:Two prototypes, "CF-LTW-X" and "CF-LTX-X" used for company engineering and testing program;CL-41A:A total of 190 trainers produced for RCAF and CF use as the CT-114. A number were modified with smoke generating systems and other modifications for the "Snowbirds" aerobatic team;CL-41G:Unique version for the Royal Malayan Air Force (RMAF). A total of 20 ground-attack variants, known as the "Tebuan" in service with RMAF.;CL-41R:One conversion of "CF-LTX-X" with a
CF-104nose grafted on to demonstrate the use of CF-104/F-104G radar and avionics; no production examples were built.

Although the CL-41 Tutor has been retired from active training, 22 Tutors continue to fly with the Canadian Forces with the Snowbirds and the Aerospace Engineering Test Establishment at
CFB Cold Lake. A number of airframes are held in reserve for future deployment as replacement Snowbird mounts.
Today, at least five CL-41s fly as civilian aircraft, including one Tebuan. The original prototype, "CF-LTW-X" is displayed as a "gate guardian" at Southport Aerospace at the former CFB Portage la Prairie. while the CL-41R, "CF-LTX-X", is now part of the
Reynolds-Alberta Museumin Wetaskiwin, Alberta.
