An Airbus A319 experienced a slow increase in cabin altitude while descending through FL290. The flight crew performed an emergency descent to 9,000 feet. Subsequently, the aircraft landed in Singapore Changi Airport.
There were no injuries to any persons and no damage to the aircraft. During the occurrence, PAN-PAN was declared and flight crew oxygen system was used.
CONCLUSIONS
1. The likely cause of the excessive cabin altitude was a corruption of LFE in the CPC. The CPC manufacturer believed that the corruption arose from a fatigue solder joint on the CPC circuit board.
2. There had been past occurrences of excessive cabin altitude that were caused by a corruption of LFE value in the CPC, of which one was determined to have likely been caused by a fatigue solder joint, similar to this occurrence.
