Incident: Air Canada E190 near Ottawa on Dec 1st 2011, engine vibrations


By Simon Hradecky, created Thursday, Dec 15th 2011 22:09Z, last updated Thursday, Dec 15th 2011 22:09Z

An Air Canada Embraer ERJ-190, registration C-FLWE performing flight AC-143 from Ottawa,ON to Edmonton,AB (Canada) with 93 people on board, was climbing through FL320 out of Ottawa when the right hand engine (CF34) started to vibrate beyond limits. While actioning the relevant checklists the crew reduced the thrust of the #2 engine until the vibrations were within limits, declared PAN and returned to Ottawa. During approach the crew was unable to cross feed to counter a developing fuel imbalance. The aircraft landed safely in Ottawa with the fuel imbalance near permitted limit about 40 minutes after the vibrations started.

The Canadian TSB reported the #2 engine's fan rotor spinner had separated in flight and was ingested by the engine resulting in damage to the engine inlet and fan blades. The engine manufacturer is looking into the spinner separation. The fuel cross feed problem was traced to an intermittent computer card/wiring fault.

Incident: Jazz DH8C near Vancouver on Dec 17th 2011, engine shut down in flight

An Air Canada Jazz de Havilland Dash 8-300, registration C-GABP performing flight QK-8192 from Vancouver,BC to Kamloops,BC (Canada) with 53 people on board, was enroute at 14,000 feet about 50nm northnortheast of Vancouver when the crew observed decreasing torque indications for the right hand engine (PW123) and shut the engine down. The aircraft returned to Vancouver for a safe landing about 20 minutes later.

The Canadian TSB reported maintenance replaced the right hand engine's mechanical fuel control (MFC).

A replacement Dash 8-300 reached Kamloops with a delay of 100 minutes.

I was on AC206 today. on approach into YYC flight crew received cautionary message, aborted landing to perform checklist. after go around and second attempt, same message was returned to crew, crew decided that after performing checklist a landing could be made.

Cautionary message indicated failed steering gear, flight crew had to resort to differential braking and power to taxi into gate.

could not find CADORS on this event.

CADORS don't appear for a couple days. I expect Simon will report on it on Monday.

The crew of ACA 206, an Air Canada ERJ 190, overshot Runway 34 at Calgary due to a nose wheel steering caution.

Souvlaki

"overshot"!? That makes it sound like a runway excursion. I'm sure that's been misphrased and they really meant to call it a go around like you did.

Incident: Air Canada E190 enroute on Dec 28th 2011, flaps fail

By Simon Hradecky, created Tuesday, Jan 3rd 2012 21:26Z, last updated Tuesday, Jan 3rd 2012 21:26Z

An Air Canada Embraer ERJ-190, registration C-FFYJ performing flight AC-1287 from Phoenix,AZ (USA) to Calgary,AB (Canada) with 85 people on board, was enroute at FL380 when the crew received a "Flap fail" ECAM message. The crew declared PAN and continued to Calgary where the aircraft landed safely with emergency services on stand by.

The Canadian TSB reported the aircraft had been dispatched under minimum equipment list requirements with the flap channel 2 inoperative. Maintenance replaced the left hand #3 flap skew sensor and the #1 and #2 slat/flap actuator control electronic units. The flap and slat system subsequently cycled properly.

Yeah this thread is not exactly making me want to run out and buy Embraer stock.

NAJetSet

um... you should be, clearly their revenues are up from replacement parts...

(14 hr delay! I travel YYZ-YYG 3-4x year usually via YUL or YOW. Would hope they'd allow YYZ bound passengers to hop a Dash 8 to YHZ, as there are a ton of direct YYZ flights).

An Air Canada Jazz plane aborted its flight out of Charlottetown Airport last week.

The morning route from P.E.I. to Montreal attempted to depart at 6:30 a.m. last Thursday. The 75-seat Bombardier CRJ-705 jet was travelling at high speed and accelerating down the runway when the crew noticed erratic airspeed readings.

The pilot abandoned the attempt, according to a Transportation Safety Board of Canada report.
All passengers deplaned without injuries.

A maintenance crew was called in to investigate. It checked the plane’s damaged pitot tubes, which measure the airspeed of a plane. They were replaced, but the crew could not determine what caused the erratic readings.
...
Passengers from the morning flight departed on the plane at 8:30 p.m., after a 14-hour delay.

Stranger

Strange sentence. If the pitot were damaged, surely that explains the readings. Or did they check the pitot *for* damage, did not find any, but replaced them anyway?

Or were they somehow clogged?

firequall

Strange sentence indeed. They author should have used "they" instead of "it" when referring to the maintenance crew, as well (though I would opt to refer to the crew directly in this case).

One interpretation could be that the pitot tubes were damaged, yet perhaps they could not determine the extend of the damage to the degree of determining what exactly was causing the erratic readings. Much akin to "well they're definitely broke but we don't exactly know what broke to cause these readings."

[grammaticalpedantry]
Actually, this is grammatically correct. A group is a singular entity, and is an "it".

There are some differences between North American and British English with respect to singular nouns referring to plural groups and how they are conjugated, mind. In Canada, a team *is* playing but in the UK, they *are* playing.

Incident: Air Canada A320 near Las Vegas on Jan 1st 2012, uncommanded elevator movements

An Air Canada Airbus A320-200, registration C-FDSN performing flight AC-544 from Vancouver,BC (Canada) to Las Vegas,NV (USA), was enroute at FL370 when the aircraft encountered uncontrollable pitch oscillations without altitude deviations. The oscillations continued until top of descent and ceased after the descent was initiated. The aircraft continued for a safe landing Las Vegas.

The return flight was cancelled.

The Canadian TSB reported the pitch oscillations were the result of uncommanded elevator movements. Maintenance replaced two accelerometers.

The next day the aircraft positioned to Calgary,AB (Canada) as flight AC-2047 when the aircraft again performed pitch oscillations due to uncommanded elevator movements, which ceased after the crew selected a different automatic flight control mode. The aircraft continued for a safe landing in Calgary.

The Canadian TSB reported maintenance now replaced two elevator servo control units and the #2 spoiler elevator computer, the aircraft passed a test flight afterwards and was returned to service.
