Incident at MANIWAKI QC (CYMW)

Mise à jour #1 : Le numéro et la classe d`enquête du BST ont été ajoutés. L`immatriculation de l`appareil a été ajoutée. Le BST nous rapporte que l`appareil était en croisière au niveau de vol 220 lorsque le voyant d`avertissement de la pression cabine et le voyant d`avertissement principal se sont allumés. L`équipage a suivi les procédures d`opérations normalisées (SOP) et la liste de vérification de confirmation d`augmentation de l`altitude dans la cabine. Le service de la navigation aérienne a donné une première autorisation de descendre au niveau de vol 140 et une seconde pour le niveau de vol 100. L`assemblage du masque à oxygène 02 du capitaine s`est défait en deux morceaux; le régulateur s`est détaché du masque, rendant l`appareil inutilisable. Un moyen de communication alternative par des signaux visuels de la main a été mis en place. La compagnie enquête la défaillance du masque à oxygène. Plus d`information à venir. Update #1: TSB investigation class and number inserted. Aircraft registration inserted. TSB reports that the aircraft was cruising at FL220 when the cabin pressure light and the main warning light came on. The crew followed the Standard Operating Procedures (SOP) and consulted the increase altitude checklist in the cabin. Air Navigation Services gave clearance, first to descend to FL140 and second to descend to FL100. The captain¿s 02 oxygen mask assembly came apart when the regulator separated from the mask, rendering it unusable. An alternative communication system using hand signals was implemented. The company is investigating the oxygen mask failure. More information to come.
