A Srilankan Airbus A330-200, registration 4R-ALH performing flight UL-225 from Colombo (Sri Lanka) to Dubai (United Arab Emirates) with 256 passengers and 14 crew, was climbing out of Colombo when the crew stopped the climb at about FL200 and performed a rapid descent to FL080 due to the cabin not pressurizing properly. The aircraft returned to Colombo for a safe landing on runway 22 about 45 minutes after departure.

The rotation was postponed to the next day. The aircraft was repaired, departed again and reached Dubai with a delay of about 16 hours.

Passengers reported there was no announcement by the crew, however, they were told later it had been a loss of cabin pressure. The oxygen masks had not deployed.

The crew performed an emergency descent to 8000 feet and returned to Colombo. The occurrence was rated a serious incident and is being investigated by Sri Lanka's CAA.
