Incident at 20 Miles West of St. John's (CYYT)


2011-03-24: UPDATE TSB: A11A0006: The Porter Airlines de Havilland Dash 8 Q400, registration C-GLQV, was operating as POE268 on a flight from St. John's, NL to Halifax, NS. Approximately 20 nm west of St. John's, and while climbing through 14,000 feet, a loud bang was heard in the baggage compartment and the flight crew observed an increase in the cabin altitude rate of climb. No door warnings were noted and the cabin altitude rate of climb returned to normal momentarily. When the cabin altitude began to climb again, the crew requested and received clearance to descend lower to 10,000 feet. During the descent, the crew received a cabin altitude warning and carried out checklist actions as required. Once at 10,000 feet, the cabin altitude stabilized and the crew determined that adequate fuel remained to continue to destination at the lower altitude. The flight continued normally and landed without further incident at Halifax. Following consultation with company maintenance control department, the blow out panel was reset and the aircraft was subsequently returned to service. The IIC is following this up with the company to add more detail.
2011-02-21: POE268, Dehavilland DHC 8 402, enroute from St. John?s (CYYT) to Halifax (CYHZ), reported losing cabin pressure and requested clearance to 10,000 ft. enroute. No emergency was declared and no additional assistance was required. TSB Case Closed.
