Qantas to fly one A380 again on Saturday, Rolls Royce may limit Trent 900 thrust

November 23, 2010

Qantas will have one A380 ready to fly again on Saturday 27th, 23 days after the engine explosion on QF32. Bloomberg reports:

Chief Executive Officer Alan Joyce will be on the first flight, which will go to London from Sydney via Singapore, he said at a media briefing today. The carrier will conduct further inspections with Airbus, regulators and engine-maker Rolls-Royce Group Plc before resuming other routes, it said in a statement.

The carrier will have four 450-seat A380s in service before Dec. 25, including two new ones, Joyce said. The airline is also due to receive two superjumbos next year. Joyce said it is too early to estimate the cost of the disruption caused by grounding the A380s or to comment on whether the carrier will seek compensation.

The Financial Times reports that Rolls Royce are likely to restrict the operating regime of the Trent 900 by limiting the maximum thrust that can be used,

Reports in Australia said Rolls-Royce was about to impose new guidelines on users of its Trent 900 engines stipulating that they cannot be operated at above 70,000 pounds of thrust.

Downgrading thrust to 70,000 pounds would knock out Qantas’s A380 services from Sydney and Melbourne to Los Angeles, a worrying development for the Australian airline that dominates the Pacific route.

“72,000 pounds of thrust is needed for the Pacific route,” a Qantas spokesman said. The airline would not comment on reports that at 70,000 pounds of thrust, Qantas A380s would be forced to fly to Los Angeles less than half full. It said the voluntary suspension on the Pacific route remains “until further operational experience is gained or possible additional changes are made to engines”.

“Pilots still have access to maximum certified thrust [of 72,000 pounds] if they require it during flight. It is not a manufacturer’s directive,” the company added.
