Canadair CT-114 Tutor
The Canadair CT-114 Tutor (company model CL-41) was the Royal Canadian Air Force (RCAF), and later Canadian Forces, standard jet trainer between the early 1960s and 2000. It was designed and produced by Canadian aircraft manufacturer Canadair.
Development commenced as a private venture by the company. On 13 January 1960, the prototype performed its maiden flight; a year and a half later, the Canadian Government placed a major order for the type. The RCAF would be the dominant user of the type, but a limited number were exported as well. Specifically, the CL-41G model, which was supplied to the Royal Malaysian Air Force (RMAF), served as a ground-attack aircraft up until its withdrawal.
The Tutor served as the Canadian Forces primary jet trainer from the 1960s up until 2000, at which point it was finally retired from this role, having been replaced by a combination of the newer British-built CT-155 Hawk and American-built CT-156 Harvard II. While the majority of Tutors have been retired, a small handful of aircraft are currently still being used by the RCAF's Snowbirds aerobatics team.
The beginnings of the CL-41 Tutor can be found in a decision by Canadian aircraft manufacturer Canadair to develop its own indigenous trainer aircraft as a private venture. The design itself was the product of the company's in-house Preliminary Design department. By August 1957, the basic configuration of the design had been completed, which was of a turbojet-powered, low-wing aircraft, complete with a tricycle undercarriage and a side-by-side cockpit arrangement. From the onset of development, the aircraft was intended to be a purpose-built trainer for providing elementary jet flight training, as well as additional training up to an advanced level.
The CT-114 Tutor is a single-engine turbojet-powered trainer aircraft. It was purpose-designed for the training role, and possesses numerous favourable qualities, including a high level of reliability and favourable operating economics. It is capable of a wide performance range, possessing a top speed at altitude of 795 kmh (429 kt) and a diving speed of 885 kmh (478 kt) against a relatively low stalling speed of 71kt. The Tutor is furnished with manual flight controls, which incorporate spring tabs. It is intentionally aerodynamically stable in flight, a factor which traditionally has aided in the training of fresh pilots unfamiliar with the demands of flight.
The Tutor features a side-by-side cockpit. During standard operations, the observing instructor was seated on the right-hand side and the flying student pilot on the left; normally, only the left-hand side normally featured full flight controls. However, following experiences with the Snowbirds display team, a number of aircraft were reconfigured with extra controls so that they would be flyable from either position. The cabin, which is fitted with a rear-hinged canopy over both crew members, can be pressurized to a differential of 3 psi (20 kPa), the equivalent to an altitude of about 2,000 m, for pilot comfort.
For aerial display purposes, the Tutor was readily capable of being fitted with a smoke generator, including a pair of under-fuselage pods to house the pressurized diesel fuel used; the use of red dye in the smoke was discontinued fairly quickly as it was found to be highly corrosive. Various other modifications would also be made to display aircraft; these could be routinely installed and uninstalled as airframes would regularly be exchanged between display and training flights.
Aerobatics: During 1967, a batch of 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. At the end of the 1967 season, the display team was disbanded, thus its aircraft returned to routine training duties. In 1971, a new formation team was formed at 2CFFTS (Two Canadian Forces Flying Training School) at CFB Moose Jaw, once again adopted the type. The following year, the name "Snowbirds" was chosen for the team; during 1978, the team received squadron status as 431 Air Demonstration Squadron.
Since its formation, the Snowbirds display team has regularly performed at air shows and special events, including the annual flypast on Canada Day over the capital city, Ottawa. According to journalist Guy Norris, a defining trait of their aerobatics is the physically-demanding formation flights performed, as well locally-developed manoeuvres such as the "Big Goose'. Unlike most display teams, the Snowbirds do not have a support aircraft; all spares and useful material could be carried by the aircraft themselves in storage areas located in the nose or the wing root.
Those Tutors used by the Snowbirds feature several modifications distinguishing them from standard examples; these include a smoke generating system, an highly-recognisable paint scheme unique to the display team, and a highly-tuned engine for greater responsiveness during low-level flying. Reportedly, display pilots would deliberately fly their aircraft using an above-average level of nose-down trim so that pushing the stick down would become unnecessary. The Snowbirds' aircraft would regularly be cycled with standard training aircraft, allowing the team to operate airframes with comparatively low accumulated flight hours. Wikipedia

Initially delivered to Portage, MB. Flown by Golden Centennaires Aerobatic Team. On 15 February 1967, the lead solo with the Centennaire Aerobatic Team, took off from CFB Comox in # 26176 as part of a nine-plane formation. The purpose of the flight was formation and solo practice, followed by a combined rehearsal over CFB Comox.After reaching the practice area the team began practicing its nine-plane sequences with recoveries approximately 1,000 ft above the ground. Two looping manoeuvres followed by a roll to the right were carried out. After the recovery from the roll and at some point during the commencement of a climbing turn to the right, the horizontal stabilizer of the Number seven a/c came in contact with the left wing tip of the a/c behind him and to his right. The number seven a/c was rapidly pitched up and to the left of the formation. The horizontal stabilizer separated from the a/c and fell to the ground in two pieces. The a/c pitched over and crashed into the trees. No attempt to eject was made by the pilot. The Investigation considered the possibility that the pilot made an error and lost control of his a/c. There was also the possibility that some restriction in either the elevator or aileron control system created a problem. The elevator control rods aft of the engine were found intact and free to move with no indication of jamming. A wrench was found in the wreckage. However it could not be concluded that the wrench played any part in the jamming of controls. Some type of distraction or combinations of distractions could have caused the pilot to move momentarily within the formation. It was found that #1 and #2 inverters had failed before the crash. This would explain why there was no transmission from the pilot either just prior to or following the collision. It is believed, that the pilot realized his radios were not working sometime during the roll. In order to regain communications, the pilot would have had to take his left hand from the throttle to reach back for the emergency UHF switch. For a very short period of time, he would not have been able to make the power increase necessary to maintain position on the outside of the right turn. Any further distraction or unexpected turbulence might have been sufficient to bring the two a/c together. The precise cause of the accident was undetermined. The most likely causes were: The pilot's distraction as a result of possible inverter failure; or a control restriction as a result of FOD in the form of the wrench found in the wreckage.Kestrel Publications1966-05-06 Taken on Strength 2021-12-29
