Qantas extends A380 grounding as probes oil leaks

LONDON/SYDNEY (Reuters) - Australia's Qantas Airways has grounded its A380 fleet for at least three more days as it investigates oil leaks that might have caused the engine explosion on a Sydney-bound flight last week.

The incident has rattled the global aviation industry, which is recovering from heavy losses during the global economic downturn, and has been damaging for Rolls-Royce, which makes the Trent 900 engine that broke apart on the flight, which made an emergency landing in Singapore.
