Incident at North Atlantic

At 1222Z, at 4739N 03436W, Gander Oceanic received an automated emergency report, from an eastbound AeroMexico Boeing 787-8 (AMX003) from Mexico City, Mexico (MMMX) to Paris, France (LFPG), declaring a MAYDAY due to an engine failure and was diverting to Gander, NL (CYQX). At 1228Z, the international flight service station (IFSS) delivered, and AMX003 read back, a clearance on high frequency (HF) radio to turn back to CYQX. After the clearance had been issued several automatic reports were received indicating that the flight was still proceeding eastbound. At 1240Z, an automatic report was received indicating that operations were normal and that the flight was continuing to their destination. At 1246Z, an automatic message was received indicating that the emergency message was triggered without apparent reason. No other traffic was affected.

Incident at 50N 050W (ATS operating irregularity)

UPDATE: TSB#A16A0049: D-CONU, a Learjet 55 aircraft, was about 30 nautical miles east of 50N 050W and proceeding north eastbound when it descended without clearance from FL410 to FL400 due to an outside air temperature exceedance. This caused a loss of separation with a westbound American Airlines Airbus A330-200 at FL400. The two aircraft came within approximately 50 nautical miles horizontally in lieu of the required 60 nautical miles. Air traffic control vectored the Learjet into radar coverage and descended it to FL290 for the remainder of its flight to destination.
At 1636Z, 30 miles east of 50N 050W, a German corporately registered Learjet 55 (DCONU/IFA1301) from St. John's, NL (CYYT) to Keflavík, Iceland (BIKF) advised Gander oceanic via the international flight service station (IFSS), that they had descended without clearance from FL410 to FL400. The flight was unable maintain flight level due to air temperature. The flight was switched to Gander high domestic and was vectored westbound into domestic airspace and given descent to FL390. The flight was subsequently issued an oceanic clearance at FL290. Less than minimum separation occurred with an American Airlines Airbus A330-243 (N282AY/AAL743) from Barcelona, Spain (LEBL) to Philadelphia, PA (KPHL) at FL400.

Incident at Vicinity of 45/45

UPDATE: TSB Report#A14A0039: The two US Airways A-330's; flight AWE704 (registration N273AY) and flight 786 (registration N272AY) aeroplanes were enroute from Charlotte (KCLT) to Frankfurt (EDDF) and Paris (LFPG) respectively. Flight 704 was 4 minutes ahead of flight 786 at flight level (FL) 370 on the same route and requested climb to FL390. Flight 786 was at FL390; Gander Oceanic cleared flight 704 to FL380 by data link. Flight 704 climbed to FL390, Gander received a warning and gave immediate descent to flight 704 to maintain FL380. A loss of separation occurred as the two flights were, for a short time, 4 minutes apart at the same flight level.
A US Airways Airbus A330-300 (N273AY/ AWE704), from Charlotte, NC (KCLT) to Frankfurt (EDDF), requested climb from FL370 to FL390 via CPDLC at 0050Z. Gander Ocean coordinated FL380 with New York Oceanic Area Control Centre (OAC) and issued a climb clearance via CPDLC to FL380 at 0052Z with an advisory message of Unable Higher Due Traffic appended as per normal procedure. AWE704 did not send back an acknowledgement message as required and commenced climb. At 0055Z automated position reports warned Gander Ocean that AWE704 was climbing past FL380 and Gander Ocean immediately contacted Gander International Flight Service Station (IFSS) to confirm the Flight Level. AWE704 levelled at FL390 4 minutes ahead of US Airways Airbus A330-300 (N272AY/ AWE786), from Charlotte, NC (KCLT) to Charles de Gaulle (LFPG), on the same route at FL390 and indicated they were cleared to FL390. Gander Ocean gave an immediate descent to AWE704 for FL380 and the aircraft levelled off at FL380 at 0059Z. AWE704 later confirmed that the altitude assigned via CPDLC was FL380 and not FL390.

December 8, 2012

Incident at Vicinity of DOTTY Intersection

XA-FLY, Lear Jet 60, enroute from Halifax (CYHZ) to Keflavík (BIKF), had a flight plan route in part which contained YJT DOTTY HECKK. XA-FLY was handed from Moncton Area Control Centre (ACC) to Gander ACC just after the aircraft passed CYJT at approximately 02:36Z at 41,000 feet. Upon initial contact with Gander, the High Level controller assigned XA-FLY the Clearance Delivery frequency and instructed the aircraft to monitor the High Control Frequency as well. At approximately 02:40Z the High Level controller observed that XA-FLY was not proceeding to DOTTY Intersection but was tracking to CYAY instead. Multiple calls were made to XA-FLY to verify the flight plan route but XA-FLY did not respond. The High Level controller, several aircraft, adjacent sectors, Clearance Delivery and the International Flight Service Station (IFSS) all attempted multiple calls to XA-FLY without success. At approximately 03:00Z XA-FLY climbed from 41,000 feet to 43,000 feet as per their Oceanic Level but without the High Level controller's approval. There was no traffic. The oceanic clearance stated that from HECKK intersection, maintain 43,000 feet. XA-FLY estimated HECKK at 03:13Z. At no time did XA-FLY squawk a Lost Communications code. Contact was re-established through satellite phone with XA-FLY after HECKK and the balance of the route was confirmed. XA-FLY was sent to Gander IFSS and upon initial contact, XA-FLY advised the IFSS that they did not have a High Frequency (HF) radio. The aircraft's 50W position report was received 45 minutes late after multiple attempts to obtain the report.
