The aircraft was on a scheduled flight from Manchester to Jersey, in the cruise at FL250, when there was a loss in cabin pressure with an associated warning. The crew donned oxygen masks and carried out an emergency descent to FL100. The crew obtained ATC clearance to continue the flight to Jersey at FL100 and informed the passengers about the pressurisation problem and their intentions. The remainder of the flight was uneventful and the aircraft landed in Jersey. The loss of pressurisation was caused by a faulty outflow valve, which was replaced and the aircraft returned to service.
