Xanadu 16 YMML Blunder
Another one for the collection.
Occurrence Briefs are concise reports that detail the facts surrounding a transport safety occurrence, as received in the initial notification and any follow-up enquiries. They provide an opportunity to share safety messages in the absence of an investigation.What happened On 2 December 2018, an Airbus A330 aircraft departed Melbourne, Vic. on a scheduled passenger service to Kuala Lumpur, Malaysia. Prior to take-off, the crew noted prevailing weather conditions could be challenging and it was decided that the captain would be pilot flying for the take-off and hand over to the first officer later during climb. The crew received a departure clearance from runway 16 on the BISON 5 Standard Instrument Departure (SID). As the aircraft lined up, the crew received a report that the last aircraft to land encountered windshear. The captain assessed that it was safe to depart. Due to possible windshear, it was decided to use maximum take-off thrust. The crew reported a normal take-off. Passing 500 ft above mean sea level (AMSL), the captain engaged the autopilot and reduced the power to climb thrust. The climb rate of the aircraft then reduced and the aircraft levelled off around 760 ft AMSL. The crew, suspecting windshear, retracted the flaps and then set take-off/go around (TOGA) power. The ground proximity warning system “DON’T SINK” alert triggered and the airspeed increased beyond the flap retraction speed up to a maximum of 236 kts until the flaps fully retracted. The aircraft continued to fly level to a position 4 NM from the airport, 400 ft above ground level, with an airspeed of 276 kts. 45 seconds after initial engagement of the autopilot, the captain then disengaged the autopilot and flew the aircraft manually. The captain commenced a climbing turn to follow the SID. During the turn, the angle of bank increased to a maximum of 46 degrees. The aircraft regained the SID, the autopilot engaged, and the flight continued to depart for Kuala Lumpur. Post-flight, it was determined that altitude (ALT) mode was selected on the autopilot. This caused the aircraft to level off and accelerate. The crew were not aware of this at the time. It is suspected that the captain inadvertently pushed the ALT button which was not detected by the crew. This resulted in the aircraft levelling off at low altitude and allowed the speed to increase, resulting in an airframe overspeed.Safety action As a result of this occurrence, the operator has advised the ATSB that they have taken the following safety actions: The details of the event have been shared with all crews to highlight the incident and the need for crews to be autopilot mode aware. The operator has also conducted further simulator training for the crew involved.About this report Decisions regarding whether to conduct an investigation, and the scope of an investigation, are based on many factors, including the level of safety benefit likely to be obtained from an investigation. For this occurrence, no investigation has been conducted and the ATSB did not verify the accuracy of the information. A brief description has been written using information supplied in the notification and any follow-up information in order to produce a short summary report, and allow for greater industry awareness of potential safety issues and possible safety actions. __________

FMA reading and support at its best.

Doesn't surprise me at all. The Bus is a clever Plane but not when it's flown by incompetent drivers who are behind the aircraft! I loved flying the Bus but if it's not doing what you expect it to do fly the bloody thing to get it to do what you expect! It's no different than a B58, power + attitude = perf!! |
power + attitude = perf |
Rubbish in, rubbish out...and a mindset of if it all gets too hard...A/P engaged. I see the same mindset and methodology when I fly with FOs and Captains from specific countries and cultures. |

I don’t know what’s more disturbing. In that they flew 400ft level, increasing a/s, flap out, wx around, over suburbia or the fact the ATSB is sidelining it as a ‘brief’ with nothing to see here let’s move along now.... The safety actions, like the many they quote in previous incidents, really don’t seem to be getting across. |
Reveal who is receiving the bribe, someone is! |
What is strange is they state they thought they were encountering wind shear so retracted the flaps. |
Climb thrust at 500 AGL, is this an Air Asia cost cutting measure? How do you over speed the flaps if you retracted them? (yeah I know it's possible to over speed while they're retracting but with climb thrust set?) Retracting flaps and setting TOGA whilst in alt hold, outstanding systems knowledge :ok:

FOs sector.
nah mate, looks challenging (wtf) Ive got this FFS |
Captain was probably an expat |

An A330 at 400 ft AGL 4 miles from the airport doing well over 270+ knots would be Airshow material! The F/O might have done a better job, they often do! |
I'm just an SLF lurker, but I have to say, at an AGL of only twice the length of the aeroplane itself, and covering its own length in less than half a second, I'd be one concerned punter looking out at the window. Then the G loading of the 46 deg turn..
Seems it's a only a matter of time with this mob.. I certainly would never fly with them, and I tell everyone I can the same. |
Lucky the Captain flew. The FO might have accidentally not nearly killed everyone.

ATSB segment from the CVR. CM2: Captain, there is an Airshow at Avalon coming up, that would be spectacular to watch CM1: Hold my Teh Tarik |

An interesting insight into what is going on in many flightdecks of carriers visiting our major cities. But the CASA pursuit of Community Service Flights's continues.
