The aircraft was operating a multi-sector cargo rotation, with the first sector from Shannon Airport (EINN) to Cork Airport (EICK). After its earlier arrival at EINN, the aircraft was parked adjacent to the east apron hangar where loading took place.
Following engine start, the aircraft commenced its taxi with a slight right turn towards the lead-out line to the taxiway. During the turn, while under marshaller’s instructions, the left wing-tip came into contact with the hangar cladding. No persons were injured. Although the aircraft carried a small quantity of dangerous goods, they posed no hazard as a result of the impact. The parking area used at EINN was not suitable for an ATR 72 as this is a larger aircraft than the ATR 42 which was normally used for this operation.
