Narrative:

On climb out through FL240; we turned off engine and wing anti-ice. We got a single chime with yellow light and ECAM message. Both left and right wing anti-ice valves failed to close. Recycled. This time; the left closed; but the right still failed to close. Recycled again. Both valves closed normally. Operations normal. Passing FL280 a new chime and ECAM message came on. Left pack failure. Shortly after leveling at FL300 we had a right pack failure (dual pack failure -- no such checklist). Requested descent from ATC to 10000 ft and started down while working with checklists and also started APU. ACARS to flight control. Before we reached 10000 ft we had both packs operating normally. Again. Proceeded to ZZZ uneventfully; operations normal.

Title: A300 SUFFERS PRESSURIZATION FAILURE FOLLOWING AIRFOIL ANTI-ICE VALVE ANOMALIES.

Narrative: ON CLBOUT THROUGH FL240; WE TURNED OFF ENG AND WING ANTI-ICE. WE GOT A SINGLE CHIME WITH YELLOW LIGHT AND ECAM MESSAGE. BOTH L AND R WING ANTI-ICE VALVES FAILED TO CLOSE. RECYCLED. THIS TIME; THE L CLOSED; BUT THE R STILL FAILED TO CLOSE. RECYCLED AGAIN. BOTH VALVES CLOSED NORMALLY. OPS NORMAL. PASSING FL280 A NEW CHIME AND ECAM MESSAGE CAME ON. L PACK FAILURE. SHORTLY AFTER LEVELING AT FL300 WE HAD A R PACK FAILURE (DUAL PACK FAILURE -- NO SUCH CHKLIST). REQUESTED DSCNT FROM ATC TO 10000 FT AND STARTED DOWN WHILE WORKING WITH CHKLISTS AND ALSO STARTED APU. ACARS TO FLT CTL. BEFORE WE REACHED 10000 FT WE HAD BOTH PACKS OPERATING NORMALLY. AGAIN. PROCEEDED TO ZZZ UNEVENTFULLY; OPS NORMAL.
