[edit] Design

The aircraft is constructed of advanced composite materials. The main fuselage and each wing is a single piece. It has a fixed Tricycle undercarriage with spatted wheels, a short nose bearing the 180 hp engine and a 3-bladed variable-pitch propeller. The cockpit features a broad canopy with good forward visibility, with side-by-side seating for pilot and student. The wings are tapered with square tips and the empennage consists of a large fin and rudder with an oblong tailplane with square tips mid-set to the fuselage.

The aircraft is capable of basic aerobatic manoeuvres (limited to +6G and -3G)

[edit] Grob Tutor

Until 2005 the Tutor was used by RAF University Air Squadrons to provide Elementary Flying Training (EFT) to university students, mainly sponsored by the RAF. From 2006 UAS students are no longer taught EFT, they follow an unassessed flying syllabus with similarities to EFT, but with reduced flying hours. The course is 36 hours with the possibility of progression to more advanced training.

RAF EFT is taught on the Grob Tutor at RAF Cranwell, Wyton and Church Fenton. These reserve squadrons teach the EFT syllabus to direct entrants and former UAS students. Afterwards the students are streamed according to ability: Fast Jet, Rotary Wing or Multi-Engine or non pilot roles.

The Tutor is used by AEFs [Air Experience Flights] to provide flying experience to cadets of the Air Training Corps and Combined Cadet Force. The Tutor replaced the Scottish Aviation Bulldog in these roles at the turn of the century.

The Tutor fleet is owned and maintained by a civilian company, VT Aerospace, and carries British civilian G-BY** registrations under a Private Finance Initiative (PFI) scheme. The aircraft are painted overall white with blue flashes and RAF roundels.

In 2009 some Tutor squadrons began to receive new Enhanced Avionics (EA) Tutors, with an updated and enhanced instrument panel, featuring a Garmin GNS 430W GPS system, digital HSI and digital engine instruments. These aircraft all have the registration G-CG**. Other than the cockpit modifications these aircraft are exactly the same as the standard tutors with the exception of an extra arial for the new GPS system.

[edit] Incidents

There have been three major incidents in its RAF service to date. The Tutor has a good safety record when compared with its predecessors, the Scottish Aviation Bulldog and the de Havilland Chipmunk.

In June 2004, a Tutor lost a propeller blade and its canopy in flight. The aircraft was landed unpowered in a field, where damage was also sustained to the undercarriage. Both pilots were uninjured. Subsequent investigation revealed cracking in the propeller blade roots across the fleet, which was grounded for modifications.

In February 2009, two RAF Tutors operating air experience flights from RAF St Athan collided in mid-air. All four occupants were killed, a pilot and a female Air Training Corps cadet in each aircraft. The two cadets killed were cousins Nikkita Marie Walters, 13, and Katie-Jo Davies, 14. Both were members of 1004 (Pontypridd) Squadron Air Training Corps. The pilots were Fg Off Hylton Price from Bridgend and Flt Lt Andrew Marsh from Vale of Glamorgan. Both were members of 1 AEF St Athan^[2]

In June 2009, a Grob Tutor collided in mid-air with a civilian glider. The two people in the Grob Tutor were killed. The glider pilot parachuted and survived.^[3]
