Travelers flying on Qantas Air will experience more delays as the company shuffles its fleet to cover the grounded A380s, Qantas spokesman Simon Rushton said.

Qantas Airlines has not resumed flying its fleet of Airbus SAS A380s for a fourth day today as it found more issues on three more Rolls-Royce jet engines following another engine blowout on its Boeing Co. 747 this weekend.

Qantas has not fully explained the nature of the issues but two engines, on aircraft in Sydney and Los Angeles, have been taken for closer inspection as a result of the eight-hour tests Rolls-Royce recommended, the Herald Sun earlier reported.

Disc recovery

Australian air safety officials are asking Indonesians to help recover a "crucial" part from the blown-out engine of a Qantas Airways Ltd. A380 jet that made an emergency return to Singapore on Nov. 4.

Residents of Batam Island should hand to local police any plane parts resembling a geared disk, the Australian Transport Safety Bureau said in a statement on its website today. The website shows a photograph of the part investigators.

Anniversary

The two incidents did not deter Qantas' 90th anniversary celebrations, which it marked with a Nov. 5 open day at its Sydney jet base. About 15,000 staff and family members attended along with Hollywood star John Travolta, who has promoted the carrier since 2002.

It is not yet certain, however, whether if these emergency grounding of its fleet will have an impact on the planned trip negotiations with American TV host Oprah Winfrey and about 300 studio audience members to Australia on an A380 next month to film episodes of her U.S. talk show.

On Nov. 5, Tourism Secretary Mr. Martin Ferguson, who personally invited Ms Winfrey, said the trip would happen as planned.
