ATSB post Beaker: From the sublime to the ridiculous -

What happened

On 10 August 2013, an Airbus A320-232, registered VH-VGR (VGR) and operated by Jetstar Airways Pty Ltd was holding short of gate D2 at Melbourne Airport, Victoria. At the same time, a Boeing B737-800, registered VH-YID (YID) and operated by Virgin Australia Airlines Pty Ltd. (Virgin) was approved by air traffic control for a pushback from bay E1 once VGR was on the gate at bay D2. The dispatcher for YID assessed VGR was on the gate and commenced the pushback. During the pushback, the left wingtip of YID collided with the tail cone of VGR, damaging both aircraft. There were no injuries.

What the ATSB found

The ATSB found that the dispatcher for YID could not visually confirm the position of VGR relative to gate D2 and assessed that because the aircraft hadn’t moved, it was on the gate. The pushback ground staff followed the normal practice for a pushback from bay E1. However, this practice did not allow for visual monitoring of the left side of the aircraft, such as by using a wing walker. This meant it was not possible for the dispatcher to identify the collision risk in time to prevent the collision.

What's been done as a result

Virgin advised that following this occurrence, they issued a local instruction to ground staff, mandating the use of wing walkers from certain bays at Melbourne Airport, including bay E1.

Safety message

This occurrence highlights the importance of ensuring that adequate clearance exists prior to commencing pushback. This includes using sufficient personnel to ensure visibility of each side of the aircraft at all times.

Last update 18 August 2016

Planetalking has picked up on this report and more than adequately highlights the totally farcical laughing stock that the ATSB has become in the world of ICAO Annex 13 aviation accident/incident investigative authorities:

ATSB takes three years to investigate pushback bingle

Australia's safety investigator exhaustively concludes that airlines need to keep a sharp lookout while reversing their jets. Really? Yes.

This is the Virgin violated tail cone of the Jetstar A320

In what might be an attempt to embarrass Government over lack of resources the ATSB has today published its final report into a low speed terminal area bump and grind between a Virgin 737-800 and a Jetstar A320 at Melbourne Airport three years ago on August 10.

It was a minor incident although it carried the risk of a becoming major had fuel in the wing of the Virgin flight caught fire when it ripped off the tail cone of the Jetstar plane.
After 36 months the ATSB concluded that:

This occurrence highlights the importance of ensuring that adequate clearance exists prior to commencing pushback. This includes using sufficient personnel to ensure visibility of each side of the aircraft at all times.

No shit Sherlock. This is really laying it on the line about the under funding of the transport safety investigator. No-one takes three years to investigate the aviation equivalent of a car in a shopping carpark reversing into a stationary vehicle.

The clear message, and it is a genuine safety message, is that the ATSB has been so gutted of resources that this bingle which should have taken less than a month to exhaustively investigate was left to only fitful moments of attention for three years while the safety investigator struggled to sort out more serious matters.

Not that it always succeeds in such efforts. It not only screwed up a compromised investigation into the Pel-Air medivac charter crash of 2009, but seems hopelessly lost in dealing with its past serious errors and coming up with a credible and comprehensive new final report.

It took three years to fail to address the principle safety issue which saw a Virgin and a Qantas 737 both forced to land short on fuel at a fog shrouded airport in Mildura the same year because neither needed to be fuelled under Australia rules to find an alternative to Adelaide airport when it was closed by a deterioration in the weather when neither had anywhere else they could go.

But while there are many valid grounds for criticising or despairing about the ATSB, it hasn’t been given the government support necessary to actually do its job in a timely manner.  It treatment is a reflection on successive governments who have adopted policies of cutting back on spending on public services until they break.

If the ATSB can’t deal with a pushback incident at Melbourne airport in less than three months let alone three years, it is broken.

It may be severely broken but the questions are can it be fixed; is Greg Hood the man to fix it; and/or has he been given a mandate to fix it? If the answer is no to any of those questions, then I am afraid the ATSB is doomed to irrelevance and the eventual scrap heap...
