Air Inuit flight AIE551, a Beech B350, was on an instrument flight rules flight from Kuujjuarapik Airport, QC (CYGW) to Kuujjuaq, QC (CYVP). While level at flight level 330, approximately 120 NM northeast of CYGW, the "CABIN ALTITUDE" indication lit up, as did the aural alert. The crew noted that the cabin altitude indicated 11,000 feet. After unsuccessful attempts to resolve the situation, a descent was requested and, since descent was only authorised up to flight level 290, the crew declared an emergency (PAN PAN) in order to descend further. At flight level 250, the cabin altitude dropped below 10,000 feet and remained stable. The crew reported that the situation was under control and cancelled the emergency. The aircraft landed safely at CYVP.
