An emergency involving a flight of Malaysia Airlines forced to return to Brisbane last week seems to have been caused by a failure of the inspection before the flight.
The PM includes four plastic lids placed on vital gauges that should have been removed were wrongly left in place.
After take-off, the lids melted and jammed the Pitot tubes used to calculate the speed and altitude of the cockpit crew
An investigation by the Australian Bureau of Safety and Security Transport is now trying to determine who is responsible. It was 11:18 pm on July 18th when MH134 left Brisbane
When the plane climbed, the cockpit crew found that they had no indication of their height or their flight speed. pan alert, a step below a mayday call, and returned to Brisbane.
A week later, the plane is still in Brisbane.
Malaysia Airlines in a statement tonight said that the A330 is undergoing pre-flight inspection.
"This usually means that there is something serious"
"We always see this sort of thing from the airlines," said Steve Purvinas of the Australian Licensed Aircraft Engineers Association
. say: there was a minor incident that made us fly back, the plane has a minor problem, it 's been on the ground since, like, three months – as long as they want to. to have on the ground.
"This usually means that there is something serious that they can not repair, and in the case of this Malaysian plane, it's certainly a little more fake than just a few Pitot covers that were left on Pitot probes. "
There are four pitot probes at the front of the plane that measure air when it enters the pitot. probe, and it transmits the data into the data computer, explains Mr Purvinas, who is the main source of measurement of air velocity. Another piece of information needed to get this air speed is an altitu
In Brisbane, there is a problem with insects, especially wasps, which build hives at the same time. probes in as little as 20 minutes
. the probes to prevent the wasps from entering.
"It appears in this case with Malaysia Airlines planes that no one checked the plane before it was removed and that these lids were still adjusted, which means that you can not measure when you start moving, "said Mr. Purvinas
Who is responsible for removing the pitot covers?
The ground engineering company that offers its services to Malaysia Airlines in Brisbane is Aircraft Maintenance Services Australia (AMSA).
The ABC approached them
A pre-flight inspection is also performed by a member of the technical team.
James Dixon, a retired retired A380 pilot, told the PM that a person would have confirmed that she had made a final walk around the plane, checking that these flags were not there.
"The engineer goes one last step after all the doors are closed, after all the catering trucks are gone, to make sure no one is hitting the plane with a truck. restoration, to make sure that there are none of these flags hanging down saying "remove before the flight".
Other pilots and engineers aeronautical reported that hydraulic fluid had leaked from the aircraft, either during the man's pre-takeoff
The investigation is being conducted by the Australian Transportation Safety Board, which will produce a preliminary report in a few weeks.
