Occurrence Reports

Mayday with VFR pilot stuck in IMC.  This pilot did however have basic IF skills and did not lose situational awareness; with the help of ATC a safe landing was made at a major airport.
Engine Failures (6) including rough running, return to land and propeller malfunction.    Lycoming (3), Continental (2), PWC PT6 (1).
Airprox and Near Miss Reports (5) plus TCAS RA (1).
Landing Accidents (2) 
Take-off without Clearance (1) aircraft doing circuits was cleared to LAND, but carried out a touch and go.
Runway Excursions (1)
Runway Incursions (10)  One aircraft crossed a red stop bar under circumstances that were at least understandable.  The pilot had been given clearance to line up behind the landing Cessna and did so, but before the stop bar had been switched off.  The rule is however that aircraft may not cross a red stop bar; it must be switched off.  Following the Tokyo accident, use of red stop bars may hopefully become more widespread.
Maintenance Reports (4)  Significant faults after maintenance (2).  Repetitive faults (3).
Taxiing Events (4) including ground handling. Ground vehicles (3).
Loss of Coms (3)
IFR Level Bust (22)  A significant increase, perhaps due to an increase in IFR flying carried out in winter.  9 were considered to be altimetry, i.e. failing to set 1013 when climbing to a FL or QNH when descending to an altitude.  IFR pilots may wish to review their altimeter setting procedures.
VFR Level Bust (3)  Climbing above a ‘not above’ altitude.  Every departure briefing should include the headings to fly and the level-off altitude..
Fire, Smoke or CO Warning (3+1)
Alternator Failure (2)
ATC Coordination of IFR GA Flights (1)
Fuel Leak in Flight (1)
Flap Failure (1), C172
Throttle Frozen (1) jet, became free at low altitude
Ailerons Frozen (1)
Instrumentation:  EHSI and EADI erroneous and failed (1).  Multiple unrelated failure indications (1).  Both were BE200 Kingairs, possibly retrofitted with glass cockpits.  Flight director erroneous indication after take-off at night over the sea leading to temporary loss of situational awareness.  All were correctly handled by the pilots.

Airspace Infringements

Airspace categories affected were:
[Table being updated] 

Various contributory factors were:

Inadequate planning (1) Paper chart inaccessible behind the seat, no printed flight log, GPS tablet failure. T
Weather Factors including turbulence (1), into sun.
Transponders Mode C faulty or over reading (3) + (1) altimeter error of 100ft.S
Take Two (3) T
Relative navigation ()
Confusion of CAS bases (2) including moving map presentation. S
Chart obscuration or presentation (1) reported
Altimetry (9)  All were of IFR flights failing to set 1013 when climbing to a FL or QNH when descending to an altitude. S
North Weald Departures/ Arrivals (2) S
Moving map failure or not used (1) S
Farnborough CTR/CTA (1) S
Distractions:- Workload (-), instructing or task (-), tech problems (2), passengers (2).
London FIS (1).
Avoiding VFR traffic (1)
– a reflective flying object.
Glider infringements (1) perhaps no choice but IFR traffic was affected.
Misunderstood clearance (1)
Inadequate monitoring of autopilot (1)
Instructor on board (-) cases reported, student solo (1)
