Narrative:

Outboard #2 side main landing exploded in wheel well en route to swf. Tire caused top back side of engine nacelle and exhaust pipe to be blown off aircraft. En route ZZZ to ZZZ1 at 4000 ft, approximately 35 mi wsw of swf, a loud bang occurred and aircraft shuddered a bit. After that, we received a right gear door light. We then also noticed a loss of all hydraulic fluid on the #2 side. I disengaged the autoplt and found no unusual handling characteristics of the aircraft. Appropriate checklists were run. Flight attendant notified us that some pieces were missing on the #2 engine nacelle. An emergency was declared with equipment standing by. Passenger were braced and landing was uneventful. Upon clearing runway, aircraft was stopped on taxiway and engines shut down. We evacuate/evacuationed passenger out of main cabin door as a safety precaution. Callback conversation with reporter revealed the following information: the reporter stated the outboard tire on the right main gear exploded in the nacelle causing extensive damage to the hydraulic lines, top and right side of nacelle, exhaust stack and trailing edge flap from the fuselage to the nacelle. The reporter said the right hydraulic system pressure and quantity was lost. The reporter stated the incident is still under investigation and no preliminary findings have been released. The reporter said the tires had been svced per the maintenance manual using dry nitrogen.
