Narrative:
The DHC-8-402 aircraft was involved in a serious incident with smoke in the cabin and cockpit while operating a scheduled flight from Hyderabad to Jabalpur resulting in a diversion to Nagpur, India. The flight took-off from Hyderabad at 07:53 UTC for Jabalpur. At 08:30 UTC, while cruising at FL250 and about 140 Nm from Hyderabad a cabin crew member reported to the captain that there was smoke in the cabin. The captain instructed the cabin crew to check the cabin for any source of fire. The cabin crew checked the whole cabin but did not find any source of fire. The cockpit crew then decided to divert to Nagpur which was around 80 Nm from their position. At around 08:33 UTC, the cockpit crew contacted Nagpur ATC and informed that they are making priority landing at Nagpur due to smoke in the cockpit. The crew also asked for an emergency descent and safety services on arrival. Accordingly, at 08:37 UTC a full emergency was declared at Nagpur Airport. The aircraft was then cleared by ATC for landing at Nagpur with visibility 3200 meters and winds calm. During descent, aft baggage cargo smoke warning along with fire detected warning light came ON at master warning panel in the cockpit and the aft cargo fire extinguisher was operated from the cockpit. Thereafter, the smoke was also noticed in the cockpit and the crew donned their oxygen masks. The captain then asked the co-pilot to carry out the QRH (Quick Reference Handbook) actions for fuselage fire, smoke or fumes. The crew heard the aural warning (smoke detector) for lavatory and the forward cargo baggage extinguisher was operated from the cockpit. Accordingly, the captain instructed them to secure the cabin and informed that they were going to land at Nagpur. During approach, low oil pressure warning for engine # 2 came
ON. At 08:56 UTC, the aircraft landed safely on runway 32 and taxied to the main isolation bay with follow me service and fire services. After reaching the bay, the PIC shut down the engine and instructed cabin crew to evacuate passengers from the left side. All passengers were evacuated from the left side. As per the statement of the cabin crew, post-evacuation, while carrying out the cabin search they observed some inflated life vests lying in the cabin. There was no injury to passengers during evacuation. The crew also evacuated the aircraft from the left side. At 09:23 UTC, full emergency was withdrawn by ATC. There was no injury to any occupant on board the aircraft.

Probable cause of the incident:
The incident occurred as No. 3 Bearing Carbon Seal failed in service resulting in oil leak into the gas path causing oil fumes getting into the aircraft cabin through the Bleed Off Valves.
