Description

The following is a selection of reports relating to accidents and serious incidents which involved Airspace Infringement.

Controlled Airspace Incursion

  • EUFI / A321, en-route, near Clacton UK, 2008 (On 15 October 2008, following participation in a military exercise over East Anglia (UK), a formation of 2 foreign Eurofighters entered busy controlled airspace east north east of London without clearance while in the process of trying to establish the required initial contact with military ATC, resulting in loss of prescribed separation against several civil aircraft.)
  • A343 / GLID, en-route, north of Waldshut-Tiengen southwest Germany, 2012 (On 11 August 2012, the augmenting crew member in the flight deck of an Airbus A340 about to join final approach to Zurich in Class 'C' airspace as cleared suddenly saw a glider on a collision course with the aircraft. The operating crew were alerted and immediately executed a "pronounced avoiding manoeuvre" and the two aircraft passed at approximately the same level with approximately 260 metres separation. The Investigation attributed the conflict to airspace incursion by the glider and issue of a clearance to below MRVA to the A340 and noted the absence of relevant safety nets.)
  • B738 / C172, en route, near Falsterbo Sweden, 2014 (On 20 July 2014, the pilot of a VFR Cessna 172 became distracted and entered the Class 'C' controlled airspace of two successive TMAs without clearance. In the second one he was overtaken by a Boeing 738 inbound to Copenhagen with less than 90 metres separation. The 738 crew reported a late sighting of the 172 and "seemingly" assessed that avoiding action was unnecessary. Although the 172 had a Mode C-capable transponder, it was not transmitting altitude prior to the incident and the Investigation noted that this had invalidated preventive ATC and TCAS safety barriers and compromised flight safety.)
  • AT72 / B732, vicinity Queenstown New Zealand, 1999 (On 26 July 1999, an ATR 72-200 being operated by Mount Cook Airlines on a scheduled passenger flight from Christchurch to Queenstown entered the destination CTR without the required ATC clearance after earlier cancelling IFR and in marginal day VMC due to snow showers, separation was then lost against a Boeing 737-200 being operated IFR by Air New Zealand on a scheduled passenger flight from Auckland to Queenstown which was manoeuvring visually (circling) after making an offset VOR/DME approach in accordance with a valid ATC clearance.)
  • P46T, vicinity Son Bonet Palma de Mallorca Spain, 2002 (On 19 December 2002, a Piper PA-46 Malibu, after takeoff from Son Bonet Aerodrome, penetrated the control zone (CTR) of Palma de Mallorca tower. The pilot was instructed to leave the CTR and the aircraft headed towards mountainous terrain to the north of the island where the flight conditions were below the VFR minimum. In level flight the aircraft impacted terrain at an altitude of 2000 ft killing all three occupants.)

Danger Area Incursion

Prohibited Area Incursion

Restricted Area Incursion

TSA Incursion

GPS VFR Navigation

  • B738 / C172, en route, near Falsterbo Sweden, 2014 (On 20 July 2014, the pilot of a VFR Cessna 172 became distracted and entered the Class 'C' controlled airspace of two successive TMAs without clearance. In the second one he was overtaken by a Boeing 738 inbound to Copenhagen with less than 90 metres separation. The 738 crew reported a late sighting of the 172 and "seemingly" assessed that avoiding action was unnecessary. Although the 172 had a Mode C-capable transponder, it was not transmitting altitude prior to the incident and the Investigation noted that this had invalidated preventive ATC and TCAS safety barriers and compromised flight safety.)

ATC Complicit

  • AT72 / B732, vicinity Queenstown New Zealand, 1999 (On 26 July 1999, an ATR 72-200 being operated by Mount Cook Airlines on a scheduled passenger flight from Christchurch to Queenstown entered the destination CTR without the required ATC clearance after earlier cancelling IFR and in marginal day VMC due to snow showers, separation was then lost against a Boeing 737-200 being operated IFR by Air New Zealand on a scheduled passenger flight from Auckland to Queenstown which was manoeuvring visually (circling) after making an offset VOR/DME approach in accordance with a valid ATC clearance.)

Aircraft not in Contact with Airspace ATC

  • EUFI / A321, en-route, near Clacton UK, 2008 (On 15 October 2008, following participation in a military exercise over East Anglia (UK), a formation of 2 foreign Eurofighters entered busy controlled airspace east north east of London without clearance while in the process of trying to establish the required initial contact with military ATC, resulting in loss of prescribed separation against several civil aircraft.)
  • F15 / E145, en-route, Bedford UK, 2005 (On 27 January 2005, two USAF-operated McDonnell Douglas F15E fighter aircraft, both continued to climb and both passed through the level of an Embraer 145 being operated by British Airways Regional on a scheduled passenger flight from Birmingham to Hannover, one seen at an estimated range of 100 feet.)
  • H25B / AS29, en-route / manoeuvring, near Smith NV USA, 2006 (On 28 August 2006, a Hawker 800 collided with a glider at 16,000 feet in Class 'E' airspace. The glider became uncontrollable and its pilot evacuated by parachute. The Hawker was structurally damaged and one engine stopped but it was recovered to a nearby airport. The Investigation noted that the collision had occurred in an area well known for glider activity in which transport aircraft frequently avoided glider collisions using ATC traffic information or by following TCAS RAs. The glider was being flown by a visitor to the area with its transponder intentionally switched off to conserve battery power.)
  • A343 / GLID, en-route, north of Waldshut-Tiengen southwest Germany, 2012 (On 11 August 2012, the augmenting crew member in the flight deck of an Airbus A340 about to join final approach to Zurich in Class 'C' airspace as cleared suddenly saw a glider on a collision course with the aircraft. The operating crew were alerted and immediately executed a "pronounced avoiding manoeuvre" and the two aircraft passed at approximately the same level with approximately 260 metres separation. The Investigation attributed the conflict to airspace incursion by the glider and issue of a clearance to below MRVA to the A340 and noted the absence of relevant safety nets.)
  • F16 / C150, vicinity Berkeley County SC USA, 2015 (On 7 July 2015, a mid-air collision occurred between an F16 and a Cessna 150 in VMC at 1,600 feet QNH in Class E airspace north of Charleston SC after neither pilot detected the conflict until it was too late to take avoiding action. Both aircraft subsequently crashed and the F16 pilot ejected. The parallel civil and military investigations conducted noted the limitations of see-and-avoid and attributed the accident to the failure of the radar controller working the F16 to provide appropriate timely resolution of the impending conflict.)
