WS flight incident master thread

A Westjet Airlines Boeing 737-600, registration C-GEWJ performing flight WS-418 from Vancouver,BC to Edmonton,AB (Canada) with 53 people on board, was climbing through FL390 to FL410 about 110nm northeast of Vancouver and 20nm west of Kamloop about 20 minutes into the flight, when mountain wave activity carried the airplane up to FL424 - above the service ceiling of the airplane at FL410 - before the crew was able to stop the ascent. The crew requested to descend to FL390 and completed the journey without further incident.

A Westjet Airlines Boeing 737-700, registration C-FWAQ performing flight WS-229 from Halifax,NS to Calgary,AB (Canada) with 108 people on board, was on final approach to Calgary's runway 16 with the first officer being pilot flying. While descending through 1000 feet the first officer kept autothrottles engaged but disconnected the autopilot to handfly the approach and kept his left hand on the throttles as per standard operating procedures. At about 150 feet AGL he felt the throttles retarding to idle, the speed fell below target speed of 133 KIAS. The announciators showed, that the autothrust system had engaged in the RETARD mode. The first officer disconnected the autothrust system and applied thrust to correct the low energy state und subsequently managed a safe landing.

The Canadian TSB reported on Aug 20th, that the flight data were downloaded and Boeing asked for assistance in the investigation. The data off the flight data recorder showed, that the #1 (left hand) radar altimeter showed a reading of -6 feet at about 147 feet AGL, the #2 (right hand) radar altimeter showed 88-136 feet at that time. The autothrottle system entered RETARD mode at 94 feet AGL with the thrust lever angles reducing at about 77 feet AGL.

The TSB continued, that the left radar altimeter is being used to determine the RETARD mode at or below 27 feet AGL. If the left hand radar altimeter is flagged faulty (red flag shown), the right hand radar altimeter is being used. No faults were shown for both radar altimeter system, hence the erroneous indication by the system was not recognized as a fault.

The #1 radar altimeter was removed from the aircraft and sent to the vendor for further analysis.

Huh? Metal bar on the back of the jump seat? I don't understand! I can't imagine what and where. And I'm an FA!

Incident: Westjet B737 near Kelowna on Dec 3rd 2009, loss of separation

A Westjet Airlines Boeing 737-700, registration C-FXWJ performing flight WS-632 from Kelowna,BC to Toronto Pearson,ON (Canada) with 99 people on board, departed Kelowna's runway 16 and was given a right hand turn for separation from IFR traffic, but was not told about a conflicting VFR Cessna 172 climbing southbound west of the Kelowna Aerodrome. The Westjet crew responded to a resulting TCAS resolution advisory, levelled off at 7300 feet, maintained that altitude until clear of conflict and continued for a safe flight to and landing in Toronto.

The Canadian TSB reported, that the minimum separation was 0.7nm laterally and 200 feet vertically as result of an operating irregularity.

Apparently it only lost the tread from one of the rear tires. Details here. Pretty routine situation but emergency landing procedures must be followed anyway.

UPDATE: WestJet makes safe emergency landing at YVR. No injuries reported.

Anyone know why yesterday's Hawaii-YVR (arriving today) flight was delayed 6 hours? Seems a bit long even if accounting for a OAK diversion in the outbound flight.
