It was held by the Europe's air safety regulator that it had washed-out a series of compulsory safety inspections on Rolls-Royce Trent 900 engines. This was done after studying into a Qantas A380 engine feast progressed.

The European Aviation Safety Agency said there would be no inquiry on turbine blades of the airlines inside the engines because investigators check for suspicions which might clarify why one of the superjumbo's engines break up mid-flight previous this month.

EASA alleged that regular checks must be done by the Airlines on the air buffer cavity and focus especially on the oil service tubes in an area housing two of the engine's three turbines.

EASA said that Airlines which operate the A380 with Rolls-Royce engines is currently Qantas, Singapore Airlines and Lufthansa. It will still have to carry out the compulsory checks after 10 flights at first and then all 20 flights.

This week Qantas said that it would restart flying the Airbus A380 superjumbo on a limited basis.
