A grob Tutor belonging to No 16 Squadron coming in to land at RAF Abingdon on it’s air day…..
he Grob G 115 is an advanced general aviation fixed-wing aircraft, primarily used for flight training. It is built in Germany by Grob Aircraft (Grob Aerospace before January 2009).The E variant with a 3-blade variable pitch propeller is in Royal Air Force service as an elementary flying trainer.
The aircraft is constructed of carbon composite materials. The main fuselage and each wing spar 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 arch with good forward visibility and 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).
 Grob Tutor
With the retirement of the Scottish Aviation Bulldog T.1 from Royal Air Force University Air Squadrons (UASs) and Air Experience Flights (AEFs), a new system was put in place for the provision of the UAS and AEF flying tasks. Aircraft were to be owned and operated by private industry, contracted to the Ministry of Defence (MoD). The aircraft chosen for this task was the Grob 115, designated Tutor T1 by the MoD. The Tutor fleet is owned and maintained by a civilian company, Babcock, and carry British civilian registrations under a Private Finance Initiative (PFI) scheme, painted overall white with blue flashes and RAF roundels.
RAF Elementary Flying Training (EFT) is taught on the Grob Tutor at RAF Cranwell, Wyton and Church Fenton by reserve squadrons teaching the EFT syllabus to direct entrants and former UAS students, with students streamed according to ability: Fast Jet, Rotary Wing, Multi-Engine or non-pilot roles.
Until 2005 the Tutor was used by UASs to provide EFT to university students, many sponsored by the RAF. From 2006, UAS students are no longer taught EFT, they follow an unassessed flying syllabus similar to EFT, but with only a 36 hour course and the possibility of progression to more advanced training on merit. The Tutor is also used by AEFs to provide flying experience for cadets of the Air Training Corps (ATC) and Combined Cadet Force (CCF), replacing the Bulldog in these roles at the turn of the century. The final AEF to receive the Tutor was 10 AEF based at RAF Woodvale in Merseyside, in 2001. 10 AEF was incidentally also the last AEF to receive the Bulldog in 1996, replacing the Chipmunk.
Five Tutor T1s are also operated by 727 Naval Air Squadron of the Royal Navy’s Fleet Air Arm for trainee pilot grading.1
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. Other than the cockpit modifications these aircraft are exactly the same as the standard Tutors with the exception of an extra VHF aerial for the new GPS system.
The Defence Elementary Flying Training School at RAF Barkston Heath also operates the Tutor.

 Incidents and Accidents
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 Athan34
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.5
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. Subsequent investigation revealed cracking in the propeller blade roots across the fleet, which was grounded for modifications. No-one was injured in the incident.
