SYNOPSIS
Shortly after take-off from Cork Airport (EICK), the flight crew were alerted to a pressurisation problem. Continuing to climb in an un-pressurised condition, the aircraft reached FL 142 before a decision was made by the Captain to return back to the airport of departure. The aircraft landed without further incident at 0755 hours. There were no injuries. The investigation found that the pressurisation system had not been correctly configured for flight.
