QANTAS near-disaster again

Qantas pilots forgot to lower wheels. Qantas is going to run out of luck soon

QANTAS has stood down two pilots after a Boeing 767 landing in Sydney came within 700ft of the ground before the flight crew realised they had not lowered the plane's undercarriage. The airline and the Australian Transport Safety Bureau have launched investigations into the October 26 incident. The pilots are due to be interviewed by authorities on Friday.

The crew on the Melbourne-Sydney CityFlyer service apparently recognised the problem and had started go-around procedures when they received a "gear too low" aural warning from the aircraft's enhanced ground proximity warning system.

It is understood investigators are looking at possible human error and a communication breakdown between the first officer and captain about who was lowering the landing gear.

According to a former Boeing 767 pilot, a crew on an instrument approach would normally start lowering the undercarriage when the plane was between 2000ft and 1500ft in order to ensure that it met requirements that the aircraft was stable and configured to land at 1000ft. In visual conditions, the aircraft needed to be stable by 500ft, but lowering the gear at 700ft or even at 1000ft was still far too late, the pilot said. Landing gear problems or gear-up situations were involved in 15 per cent of airline hull-loss accidents last year, according to an analysis by the International Air Transport Association.

But Qantas said yesterday that a crew failing to lower the undercarriage was extremely rare and it was taking the incident seriously. "The flight crew knew all required procedures but there was a brief communications breakdown," a spokeswoman said. "They responded quickly to the situation and instigated a go-around. The cockpit alert coincided with their actions. There was no flight safety issue. "The incident was reported to the ATSB and the pilots were stood down. We are supporting the ATSB's investigation and our own investigations will determine what further action might be warranted."
