January 10, 2015

Incident at ST. JOHN'S INTL NL (CYYT) (Aerodrome, runway or taxiway shutdown, Aerodrome - other)

Truck TK95 lost a wheel on the threshold of Runway 16. Runways 16/34 and 11/29 were closed, as the sweeper was over the hold short line for Runway 29. A Jazz Bombardier CL-600-2D15 (C-GJAZ/JZA8999), from St. John's, NL (CYYT) to Halifax, NS (CYHZ), was waiting for de-icing when both runways were closed. JZA8999 then decided to take Runway 20 and get de-iced. Upon taxi after de-icing, JZA8999 advised that it couldn't take Runway 20 and had to return to the gate. Runways 16 and 29 were re-opened at 0137Z. JZA8999 required more fuel and additional de-icing.

May 24, 2014

Incident at TORONTO / LESTER B. PEARSON INTL ON (CYYZ)

After take-off, the landing gear on a Jazz Bombardier CL-600-2D15 (C-GJAZ/JZA8906), from Toronto, ON (CYYZ) to New York, NY (KJFK), would not retract and the crew received ?GEAR DISAGREE? and ?PROX SYS 1? messages. The flight returned to CYYZ for an uneventful landing. Company Maintenance determined that missing dowel pins prevented rotation of the upper centering cam of the Nose Landing Gear (NLG). The landing gear logic prevents gear retraction if the NLG is not centered. New dowel pins were installed and the aircraft returned to service. The dowel pins are only accessible with the shock strut disassembled. The NLG was last repaired in November 2013 and installed in December 2013. The Company has brought this to the attention of the contract maintenance provider. The Company has also submitted SDR No. 20140528001 for this event so that it can be brought to the attention of the Federal Aviation Administration (FAA) (contract maintenance provider located in Miami, FL, USA).

Landed on 3rd attempt at 0028Z. TOCC was advised. Subsequent aircraft reported similar issues although landed without incident. ILS 14 NOTAMED unserviceable from 0045Z - 2359Z. Impact hard to categorize as runway 05/23 was closed at the time by HIAA to repair CAT II lighting. By the time 05/23 was opened weather had deteriorated to visibility below RVR 1200 so several aircraft diverted.

December 29, 2011

Incident at CHARLOTTETOWN AIRPORT

JZA7673, CL-600-2D15 , rejected take off from Runway 21 in Charlottetown (CYYG) and returned to the apron. TSB Case Closed.

The take-off was rejected at about 90 knots. During the incident follow-up, company maintenance used nitrogen to clear the pitot lines. During this operation the pitot heat came on automatically and melted the nitrogen line adapters to the pitot probes requiring both pitot probes to be replaced. As a result it was not possible to determine the initial fault. A pitot static leak check was carried out and the aircraft was returned to service.

Incident at MONTRÉAL / PIERRE ELLIOTT TRUDEAU INTL QC (CYUL) (Aerodrome, runway or taxiway shutdown)

JZA7998, a Regional Jet operated by Air Canada Jazz, was on an IFR flight from Houston (KIAH) to Montréal/Trudeau (CYUL). Upon departure from Houston, the pilot reported an overheating of the right landing gear brakes and decided to continue the flight to its destination. At 2135Z, above the Toronto (YYZ) very high-frequency omnidirectional range (VOR), the pilot declared an emergency, reporting a problem with the right landing gear and requested the presence of emergency vehicles for landing on Runway 24R. At 2205Z, the aircraft landed without incident and stayed on the Runway until 2225Z. There was a light impact on arrivals, as Runway 24 was unavailable for 20 minutes.

Incident at THUNDER BAY ON (CYQT) (Conflict - loss of separation, Communication navigation surveillance/air traffic system, ATM - other)

The Jazz Airlines CANADAIR CRJ 900 operating as JZA531, was on a scheduled Instrument Flight Rules (IFR) flight from Toronto Pearson International Airport, Toronto, ON (CYYZ) to Thunder Bay International Airport, Thunder Bay, ON (CYQT). The ORNGE commercially registered PILATUS PC12 operating as PUL108, was on an IFR flight from Sudbury Municipal airport, Sudbury, ON (CYSB). The Thunder Bay Air Traffic Controller was vectoring JZA531(south of CYQT) and PUL106 (north of CYQT) for the Instrument Landing System Runway 07 (ILS 07) CYQT. The plan was to put JZA531 first. While vectoring to final, the separation between the two aircraft reduced to 2.4nm and 300' Ops impact - unknown
UPDATE Supplemental Information received from T.S.B. Daily Notification [#A10C0034] The Bombardier CL-600-2D15, C-GJAZ (operating as JZA531) and the Pilatus PC-12, C-GRXM (operating as PUL106) were being radar-vectored for the final approach to runway 07 in Thunder Bay Ontario.

Both aircraft landed without further incident.

August 24, 2009

Incident at DUXAR Intersection (Communication navigation surveillance/air traffic system, ATS operating irregularity)

UPDATE from the TSB A09P0277: The Air Canada Regional (Jazz) CRJ aircraft, C-GJAZ, operating as JZA446, was en route from Whitehorse to Vancouver at FL390. At DUXAR, the Yukon sector controller passed the Anahim sector controller an estimate and altitude of FL390 for JZA446. The Anahim sector controller read back FL290 and this was confirmed by the Yukon sector controller. FL290 was then entered into CAATS by the Anahim controller. The discrepency was discovered when JZA446 checked in with the Anahim controller at FL390. A loss of separation had occurred because safety was not assured.
AB Controller received an estimate and altitude for Air Canada Jazz Flight JZA446, a Canadair CRJ9 IFR Whitehorse to Vancouver, at DUXAR Intersection of a time of 2220Z at FL390. The Controller read back FL290 and this was ROGERED by the YK Controller. FL290 was entered into the Canadian Automated Air Traffic System (CAATS). The aircraft showed up at FL390.

June 10, 2005

Incident at Vicinity Colorado Springs, CO

UPDATE TSB reported that the NTSB in the U.S. has downgraded this incident to a Class 5 investigation.
The Air Canada Jazz Bombardier CL-600-2D15 (RJ705), C-GJAZ, was operating as flight JZA 8501 from Houston, TX to Calgary, AB. While in the vicinity of Colorado Springs, CO at FL 410 and Mach 0.70, the flight encountered a downdraft and the stick shaker activated. Maximum thrust was set and a lower altitude was requested. The aircraft descended at approximately 1,000 fpm with a 3° nose down attitude. An attempt to recover at FL 400 was made but the stick shaker activated briefly and the descent was continued. Recovery was made at FL 380 and the aircraft returned to a planned speed of Mach 0.77. This incident is being discussed with the National Transportation Safety Board in the U.S. and there is a possibility that it will become a Class 3 investigation done by the Edmonton office of the TSB.
UPDATE This occurrence will be the subject of an investigation by the National Transportation Safety Board in Washington, DC. It will be a parallel investigation to 2005C1179, which occurred the follwing day south of Calgary and is a Class 3 investigation by Edmonton TSB.
