Incident: Air Canada B763 at Toronto on Jun 29th 2011, slat asymmetry on flap retraction

An Air Canada Boeing 767-300, registration C-GHLT performing flight AC-115 from Toronto,ON to Vancouver,BC (Canada) with 199 people on board, was climbing out of Toronto when the crew received a slat asymmetry message during flap retraction. The aircraft levelled off at 7000 feet, the crew actioned the relevant checklists but could not resolve the problem so that they declared emergency and decided to return to Toronto for a safe landing about 45 minutes after departure.

The Canadian TSB reported maintenance replaced the slat proximity sensor and associated wiring, the system tested satisfactorily thereafter.

An Air Canada Jazz Canadair CRJ-100, registration C-FWJT performing flight QK-7678 from Montreal,QC (Canada) to Boston,MA (USA) with 17 people on board, was in the initial climb out of Montreal when the crew heard a loud bang from engine #2 (CF34, right hand), felt strong vibrations, and the engine's Inter-Turbine Temperature went above limits. The crew levelled off at 6000 feet, shut the engine down, declared emergency and returned to Montreal for a safe landing about 35 minutes after departure.

A replacement CRJ-100 reached Boston with a delay of 2.5 hours.

The Canadian TSB reported that a borescopic inspection showed major damage at the stage 5 of compressor with parts of some blades missing. The engine is going to be replaced.

Incident: Air Canada B763 near Dublin on Jul 14th 2011, pressurization problems

An Air Canada Boeing 767-300, registration C-GHPE performing flight AC-895 from Dublin (Ireland) to Toronto,ON (Canada) with 234 passengers, was climbing through FL160 towards FL260 when the crew requested to level off at FL170.

The airplane descended to FL080 and landed safely on Dublin's runway 28 about 25 minutes later.

The flight was cancelled.

While taxiing in the crew requested a ground air starter unit to be available due to inoperative APU.

The airline said a pressurization indicator light illuminated shortly after takeoff. Passenger oxygen masks did not deploy. The flight is now estimated to depart the following day (Jul 15th).

A routine flight turned into a "frustrating" case of deja vu for travellers after a flight from Calgary had to return to the airport Tuesday. Not once, but twice.


Air Canada Flight 118, which departed at 11:50 destined for Ottawa, had to return to the Calgary International Airport on two occasions because of what one passenger described as the smell of smoke in the cabin.

Incident: Air Canada E190 near Calgary on Jul 19th 2011, returned twice because air conditioning problems


By Simon Hradecky, created Wednesday, Jul 20th 2011 19:26Z, last updated Wednesday, Jul 20th 2011 19:30Z

An Air Canada Embraer ERJ-190, registration C-FHNW performing flight AC-118 from Calgary,AB to Ottawa,ON (Canada) with 95 people on board, was climbing out of Calgary's runway 16 when the crew declared emergency reporting smoke in the cabin and levelled off at 8000 feet. About 2 minutes, while positioning for a return to Calgary, the crew received an EICAS message "PACK 2 FAIL" and cabin crew reported the smoke had dissipated. The aircraft landed safely about 12 minutes after departure.

The Canadian TSB reported that the aircraft was released under minimum equipment list requirements without working right air conditioning system.

The aircraft departed again and was climbing through FL250 about 70nm east of Calgary when the crew received an EICAS message indicating a 1 bleed air leak (affecting #1 air conditioning system). As result of the MEL from the previous flight and the fault the crew initiated an emergency descent to 10,000 feet and returned to Calgary again. The aircraft landed overweight but safely on runway 34 about 40 minutes after departure.

The Canadian TSB reported that the #2 air conditioning system was then replaced and tested serviceable, maintenance also performed a dual engine ground run and tested all bleeds without any fault. An overheat detection test also revealed no faults.

An Air Canada Jazz de Havilland Dash 8-100, flight QK-8730 from Montreal,QC to Quebec,QC (Canada) with 35 people on board, was climbing through 7000 feet out of runway 06L when the crew reported a problem and requested to return to Montreal. While descending to 4000 feet the crew declared emergency reporting they had a #1 hydraulic failure. They requested delay vectors for working the checklists and subsequently landed safely on runway 06L about one hour after departure. Following the landing the crew reported they might have a hydraulic leak on the left hand side. Tower instructed the crew to stop and shut both engines down.

A passenger reported that the crew announced they had problems with a hydraulic system. Cabin crew repeated the evacuation procedure over and over and during final approach instructed the passengers to assume brace positions.

It might have been a big problem if they were over Mennonite country.

Incident: Jazz DH8C at Fort McMurray on Jul 21st 2011, descended below minimum safe altitude

An Air Canada Jazz de Havilland Dash 8-300, registration C-GSTA performing flight QK-8382 from Edmonton,AB to Fort McMurray,AB (Canada) with 30 people on board, was on approach to Fort McMurray's runway 25 when the crew responded to a TCAS climb resolution advisory caused by Cessna in the right hand downwind. The aircraft was vectored on a right hand crosswind at 4000 feet, downwind at 3000 feet and was cleared to descend to 2000 feet on the base leg. Descending through 2200 feet the crew stopped the descent and queried the controller shortly followed by a ground proximity terrain warning. The aircraft climbed to 2900 feet and continued the approach for a safe landing.

The Canadian TSB said: "Safety was not assured when the aircraft was cleared below the minimum vectoring altitude of 2800 feet." NAV Canada is conducting an operational investigation. The weather at the time of the incident: wind 300 degrees true at 6 knots, visibility 6 in light rain, clouds 700 few, 1200 overcast, 3000 overcast.

Incident: Air Canada E170 at Toronto on Jul 30th 2011, rolled over approach light but no runway excursion

An Air Canada Embraer ERJ-175, registration C-FEJL performing flight AC-773 (scheduled dep Jul 29th, actual dep Jul 30th) from Newark,NJ (USA) to Toronto,ON (Canada), landed on Toronto's runway 24L and was slowing through 80 knots about abeam taxiways D1/D2 when the aircraft struck some foreign object on the runway. The airplane slowed safely and taxied to the apron, where ground staff found damage to the left main gear.

The Canadian TSB reported, that maintenance needed to replace both left main wheels. The object was identified to be an approach light to runway 33R that was recessed into the surface of runway 24L. The light was bolted to an adapter plate, all bolts were secure. The adapter plate was attached to a canister set into the ground by 6 bolts, 5 of which showed old fracture marks due to rust/corrosion and one a fresh fracture mark. The one bold with the fresh fracture marks is suspected to have fractured when the preceding aircraft landed. The light is the only one recessed into a runway surface on the entire Pearson International Airport. A temporary runway repair was done, a long term solution is being worked on.

Runway 24L was temporary closed for the needed repairs.
