The Boeing 727, owned by the President of Congo (DRC001), executed a missed approach for runway 11 at CYYT. Aircraft did not follow missed approach instructions of climbing to 2400ft on runway heading and made a right turn of approx 30 degrees. As a result Air Traffic Control had to issue further instructions to DRC001 and the other aircraft involved. Separation between involved aircraft reduced below that required to approx 1.7 nm and 400ft. No ATS involvement.
TSB Update Sept 28, 2004. A04A0125: DRC001, a Democratic Republic of the Congo Boeing 727, on a flight from Santa Maria to St. John's, NL was executing a missed approach on Runway 11 at St. John's. A Cougar Helicopters AS32, CHI31, had departed St. John's airport and was en route to the Hibernia oil production platform at 3600 feet. Missed approach instructions for DRC001 were to climb to 2400 feet on runway heading; however, during the missed approach, the aircraft turned right approximately 30 degrees and climbed to 3200 feet. Separation between DRC001 and CHI31 eroded to approximately 1.7 miles horizontally and 400 feet vertically where three miles horizontal or 1000 feet vertical separation is required.

December 18, 2003

Incident at ST. JOHN'S INTL NL (CYYT)

TSB Update - A03A0133: A Cougar Helicopters Eurocopter AS-332, registration C-GQCH, had just departed the Hibernia oil production platform with 2 crew and 11 passengers on board en route to St. John's, NL when a loud 'bang' was heard by the crew and passengers. The crew elected to return to the platform for a visual inspection. After landing, a visual inspection of the exterior did not reveal any abnormalities. After shutdown, the engines, drive train and landing gear were inspected with no observed abnormalities. Maintenance requested a hover check and cycle the landing gear. All systems other than the gear appeared to function normally. The gear was cycled to the down position but the crew did not receive a down and locked indication in the cockpit. Platform personnel, observing the extension, advised the crew that the gear did not appear to be extended properly. The crew left the hover, retracted the gear and flew to St. John's. At 30 nm from St. John's, the crew selected the gear down and again did not receive a down and locked indication so an emergency gear extension procedure was completed. A down and locked indication was obtained. Upon arrival at St. John-s, the aircraft was escorted to the apron by AFF vehicles and landed safely at 1857 NST without further incident. The AS-332 landing gear position is determined by a series of proximity switches controlled by a landing gear control circuit board. Maintenance personnel replaced the circuit board, cycled the landing gear numerous times and confirmed normal functioning of the landing gear and indication system. The aircraft was returned to service.
An AS32 Helicopter operated by Cougar Helicopters departed Hibernia for St. John's. When the helicopter was 80 nautical miles South-East of St. John's the pilot declared an emergency due to landing gear problems. The AS32 hovered in St. John's and it was determined that the gear was safely down then the emergency was cancelled and they landed at 2227Z without incident.

April 17, 2002

Incident at ST. JOHN'S INTL NL (CYYT)

The AS32 helicopter was departing Runway 02 enroute to the Hibernia Oil Platform. The flight aborted take off due to a reported activation of the fuel filter light. No assistance was required.
When the Helicopter applied power for liftoff, the airframe fuel filter impending bypass light illuminated. When power was reduced to land the light extinguished. The aircraft returned to the apron, where the fuel filter was replaced and the aircraft returned to service. Upon examination of the filter and fuel, a small amount of fine dust was found. There was no quantity of dirt found in this sample that would raise an alarm of a larger problem. TSB - NIL

Incident at Vicinity of Hibernia Oil Rig. (Other operational incident, Conflict - loss of separation, Communication error, ATM - other)

TSB Update Feb 11, 2002. A02A0011: The radio operator on the Hibernia oil rig called Gander Flight Planning and advised that Cougar 33 (CHI33), a Super Puma AS32, was requesting route 'B' at 6000 feet to St. John's. This was acknowledged by Gander; however, the radio operator on the rig assumed that this was a clearance for CHI33 and the aircraft proceeded at that altitude. Traffic in the area was a Cessna 182, ZS-KGC, en route from Lajes to St. John's which had declared that he was 'fuel critical' and had been given an altitude block of 5500 to 10000 feet. Separation was not assured.
CHI33 AS32 Helicopter departing the Hibernia Oil Rig. At 1956Z, the Radio Operator on the Hibernia Rig called Gander Flight Planning and advised that Cougar33 was requesting 6000 Route 'B' to St John's. The ATOS on Flight planning acknowledged this but the operator on the rig mistakenly assumed this was an approval to climb to 6000'. Traffic was a C182 who had declared a ""fuel critical"" and was in a block of 5500 to 10,000 enroute from the Azores to St. John's. Due to this misunderstanding, Separation was not ensured. Nil TSB

November 21, 2000

Incident at ST. JOHN'S INTL NL (CYYT)

C-GQCH, returned to the hangar just after lift off due to an left hand airframe fuel filter light. This light is the filter impending bypass indication. When the aircraft returned, maintenance carried out a filter drain and found a small amount of water in the sample. Removed and replaced the fuel filter. Maintenance did not find any more contamination in the filter bowl. The aircraft was ground run and test flown without further incident and released for service. Due to the weather that day it is suspected that water may have entered the fuel tank filler neck during the refueling process. Refueling was carried out over wing and not with the single point connection.

July 1, 1997

Incident at St. John's NFLD

C-GQCH AS32 was conducting ILS approach to runway 29 at St. John's and as the helicopter was about to touch down, the crew realized that they were lower than normal and went into the hover. However, as collective pitch was applied to start the hover the nose of the helicopter dropped resulting in the Comm antenna and the FM antenna striking the surface. Once the hover was established the landing gear was lowered and the helicopter landed without further incident. The damage was confined to the Comm and FM antenna and FM supporting structure on the fuselage. The helicopter was equipped with a horn to warn the crew that the gear was not down. However, for the horn to activate the helicopter has to be below 200 feet radar altimeter altitude and the airspeed has to be below 60 MPH. In this occurrence the autopilot was engaged and the airspeed remained above 60 MPH. At the time of the occurrence there was a 100 foot overcast ceiling. The company aviation safety officer will be conducting an investigation to determine why the check list was not followed and will also be looking at the ILS Approach Procedures.
