SpiceJet flight SG246, a Boeing 737-85R, was involved in a loss of cabin pressure on a flight to Varanasi.
This was the third sector of the day for the aircraft and first sector for both Captain and first officer. Taxi out and the takeoff was uneventful. During climb, passing FL190, #1 Bleed Trip Off annunciator came on. Associated actions as per Non Normal Checklist (NNC) were carried out and #1 PACK SWITCH was put to OFF and the #1 Bleed annunciator went off. As per PIC discretion, the flight continued to destination with single “PACK”. During descent from FL370, the crew observed steady rise in cabin altitude. While descending and passing FL332, the CABIN Altitude Horn came on. Immediately, the cockpit crew donned the oxygen masks and requested ATC for a descent to FL100 due to decompression and the same was approved by ATC. The crew declared “MAYDAY” and an emergency descent was carried out. NNC actions for “CABIN ALTITUDE WARNING or Rapid Depressurization” were carried out by the crew.
The oxygen masks were deployed inside the passenger cabin. Once the aircraft reached approx FL 100, cabin altitude was under control, the masks were removed, and the crew cancelled the distress situation. The aircraft landed safely at VNS. There was no damage to the aircraft. There was no fire and injury to any of the occupants on board the aircraft.
