The Slingsby T.67 Firefly is a two-seat civil and military primary trainer. The Slingsby Firefly is a
further developement by Slingsby Engineering Ltd. of the Fournier RF-6B. Production by
Slingsby started with nine T.67As, which were basically licence built RF-6B-120s. The first Slingsby T.67A,
G-BIOW c/n 1988, flew first in 1981. After re-development of the airplane with maximal use of glass fibre
reinforced plastics the T.67B entered production, being the first UK-certified composite aircraft. The
prototype of the T.67B, G-BUIZ c/n 1998, was flown first on 16 April 1981, and served as a development
machine. A 116 hp Textron Lycoming O-235-N2A engine powers the T.67B. Further development of the
aircraft resulted in the Slingsby T.67C Firefly. The T.67C is similar to the T.67B except for its more powerful
120kW (160hp) Textron Lycoming O-320 engine. The T-67C-3 as used by the KLS has wing tanks and a three-piece
canopy. Next to the T.67C a military version, the T.67M was introduced. The first T.67M Firefly, G-BKAM c/n 1999,
flew on 5 December 1982. 112 Slingby T.67M-260s were delivered as Slingsby T-3A Firefly to the U.S. Air Force's
Air Education and Training Command for use as trainer aircraft to screen pilot candidates. 290 civil and military
T.67s of all models were built.
In 1990, the RLS bought nine Slingsby T.67C-3 Firefly for the basic training. They replaced the eight Cessna F.152-IIs operating
in this role since 1980. The 1990-built Slingsby T67C-3 s/n 2077 was tested as G-7-136. On 16 Augustus 1990, the CofA for this
airframe was requested by Staat der Nederlanden/Rijksluchtvaartschool, Eelde, as PH-SBB. On 4 September 1990, the Slingsby T.67C-3 was
registered PH-SGB with Staat der Nederlanden/Ministerie van Verkeer en Waterstaat/Rijksluchtvaartdienst/Directie Rijksluchtvaartschool, Eelde.
When in August 1991, the KLM took over the RLS and transferred it into the KLM Luchtvaartschool: the aircraft were repainted in the basic KLM colours.
On 28 August 1991, the PH-SGB was registered with KLM Luchtvaartschool BV, Eelde. After the PH-SGB was withdrawn from use by the KLM Luchtvaartschool,
the airframe was sold and on 10 November 2009, registered witht KN Singles and Twins Aviation Consultants, Lelystad. On 17 April 2012, Slingsby
T.67C-3 Firefly PH-SGB was registered with Emma Aviation. On 20 October 2015, registration PH-SGB was cancelled as exported to the Czech Republic.
On 4 November 2015, the airframe was registered OK-WTC with Lease machines. On 25 January 2017, registration OK-WTC was cancelled as exported to
Turkey, where the airframe was registered TC-EDY with Ersin Edizyürek (Maviyol Havacilik – Blueway Aviation).
On 27 August 2005, the KLM Luchtvaartschool'
Slingsby T.67C-3 Firefly PH-SGB was seen at Groningen Airport Eelde (GRQ/EHGG).
The ICAO Aircraft Type Designator for the Slingsby T.67C-3 Firefly is RF6.
