The airplane with 11 crew and 114 passengers aboard was on a LTU flight LT230 from Düsseldorf, Germany, to Saloniki, Greece. At 10501 hrs in Flight Level (FL) 105 during climb the crew noticed a loud bang. Simultaneously, the aircraft began to yaw in combination with unusual sounds. The crew checked whether doors and hatches were properly locked.
A short time before the speed of LTU flight LT230 was increased from 250 kt to 350 kt.
Since the Electronic Centralized Aircraft Monitor (ECAM) did not indicate any malfunctions the LTU flight LT230 was continued. A short while later the cabin crew noticed that a large part of the left engine cowling was missing and reported it to the pilots.
The crew decided to abort the LTU flight LT230 and return to Düsseldorf. They did not declare an emergency. The airplane landed in Düsseldorf without any further problems. At the parking position the fire brigade determined that the left wing leaked fuel.
