Accidents & Serious Incidents involving G115

  • G115 / G115, near Porthcawl South Wales UK, 2009 (On 11 February 2009, the plots of two civil-registered Grob 115E Tutors being operated for the UK Royal Air Force (RAF) and both operating from RAF St Athan near Cardiff were conducting Air Experience Flights (AEF) for air cadet passengers whilst in the same uncontrolled airspace in day VMC and aware of the general presence of each other when they collided. The aircraft were destroyed and all occupants killed)
  • G115 / GLID, en-route Oxfordshire UK, 2009 (On 14 June 2009, a Grob 115E Tutor being operated by the UK Royal Air Force (RAF) and based at RAF Benson was conducting aerobatics in uncontrolled airspace near Drayton, Oxfordshire in day VMC when it collided with a Standard Cirrus Glider on a cross country detail from Lasham. The glider was sufficiently damaged that it could no longer be controlled and the glider pilot parachuted to safety. The Tutor entered a spin or spiral manoeuvre which it exited in a steep dive from which it did not recover prior to a ground impact which killed both occupants.)
