Melbourne runway overruns have been metres from catastrophe – Australian Aviation

Two plane got here inside metres of hitting development crews at Melbourne Airport in 2023 resulting from their flight crews being unaware of a shortened runway, the ATSB has stated.

A Malaysia Airways Airbus A330-300, 9M-MTL, handed simply seven metres excessive of labor automobiles on the finish of Melbourne’s runway 34 on the night time of seven September 2023, adopted by a Bamboo Airways 787-9, VN-A819, passing lower than 5 metres overhead 11 days later.

Runway works have been underway on the time, and whereas no one was bodily injured by the jet blasts, there was not less than one stress-related damage.

In keeping with the ATSB, whereas each crews had obtained recommendation concerning the shortened runway in NOTAMs and through the ATIS (computerized terminal info service) radio broadcast, “neither flight crew” recognized that the runway was considerably shortened.

Moreover, the airways’ respective flight dispatchers “didn’t particularly spotlight the shortened runway within the flight crews’ pre-flight briefing packages” regardless of having accounted for the decreased runway size of their indicative take-off efficiency calculations.

“Whereas each crews accessed a model of the ATIS that talked about the shortened runway, they solely famous to air visitors management the climate info from the ATIS, and never the decreased runway size,” stated ATSB chief commissioner Angus Mitchell.

“This oversight contributed to each flight crews utilizing the complete runway size of their pre-flight efficiency calculations, and subsequently conducting the take-offs with decreased thrust settings.”

Investigators pointed to the danger of human error within the “elementary pilot duty” to determine safety-critical aeronautical info earlier than a flight, and steered adjustments together with extra conspicuous airport signage, and higher communication with dispatch and air visitors management.

“The danger controls to stop these occurrences have been predominantly procedural: counting on flight crews to fastidiously assessment aerodrome info, then determine and perceive important info – on this case, the decreased runway size obtainable,” stated Mitchell.

“Counting on predominantly procedural defences to recognise and comprehend hazards doesn’t assure that flight crews will at all times have a full and proper understanding of operational circumstances.

“Contemplating the possibly catastrophic consequence of departing plane impacting an energetic works space, extra defensive layers geared toward alerting flight crews to vital runway hazards ought to be applied.”

Mitchell additionally famous that – consistent with present ICAO laws – air visitors controllers have been solely required to substantiate that the plane had obtained the most recent ATIS info, and never that the crew had understood it in full.

“Air visitors controllers have nicely outlined and set tasks, which at the moment don’t essentially require them to straight advise flight crews of all security vital info,” he stated.

“Nevertheless, the place there may be doubt or potential {that a} vital security hazard might not be understood or acknowledged, they’ll use their finest judgement when it’s prudent to intervene.”

Airservices has proposed adjustments to ATC procedures round advising crews of shortened runways, whereas CASA is about to assessment new ICAO tips on extra conspicuous airport signage.
