What happened
On May 30, 2008, at 09:50 UTC, an Airbus A320, registration EC-HGY, operated by Iberia, was performing a scheduled commercial flight from Porto Airport (LPPR) to Madrid (LEMD). Shortly after takeoff, during the climb phase of the operation, the flight crew identified a malfunction within the aircraft's pressurization system.
Following the detection of the technical issue, the crew decided to abort the departure and initiated a return to Porto. The aircraft landed safely back at the departure aerodrome at 10:03 UTC. There were no injuries to the crew and no damage was sustained by the aircraft.
The investigation
The GPIAAF did not initiate a formal investigation into this incident. Upon reviewing the available information, the agency forwarded the details to the Spanish investigative body, CIAIAC. The CIAIAC subsequently notified the GPIAAF that it did not intend to proceed with a formal investigation into the matter.
