Narrative:

On 02/wed/02 at XA45, flight XXX departed the gate at ZZZ bound for ZZZ1. I was the first officer and performed the duties of PNF on this flight. We took off on runway 29 at approximately XA55 on an assigned heading of 130 degrees and altitude of 3000 ft. Moments after reaching our assigned altitude and heading, we were given clearance to climb to 13000 ft. The captain began to advance the thrust levers and initiated the climb. Shortly after beginning the climb out, at approximately 3500 ft, a vibration was heard coming from our right (#2) engine. Immediately following the vibration, a loud explosion type noise came from the same engine and we immediately lost the thrust from the right engine. I noted that the engine indications immediately went outside of normal limitations and the aircraft yawed. The captain was able to maintain control of the aircraft without incident/problem and called for our memory items to be performed for the emergency checklist for engine fire/severe engine damage in-flight. I completed the checklist and the captain then had the flight attendant notified of our engine loss and that we would return the aircraft to the departure airport. I then completed the appropriate emergency checklist while the captain flew the aircraft, declared an emergency with ATC, and coordination our return to the departure airport. Upon my completion of the required emergency checklist, we landed at ZZZ without further incident. Upon landing, the crash fire rescue equipment vehicles inspected our aircraft for fire/dangerous conditions on the runway (runway 29). Once the crash fire rescue equipment personnel completed their inspection, we requested and were approved to return to our gate, since there was no apparent danger to the aircraft or people/crew on board. During taxi back to the gate, I called the station personnel to inform/coordination our return and have them notify dispatch/operations of our situation. Callback conversation with reporter revealed the following information: the reporter stated after pushing the thrust levers forward a vibration was noted then the explosion noise. The airplane yawed and the engine indications dropped to zero. The reporter said the airplane was flown by the captain and was manageable. The reporter stated when inspected on the ground the rear of the engine was found extensively damaged and the horizontal stabilizer had a hole in the leading edge. Callback conversation with reporter acn 539644 revealed the following information: the reporter stated the engine failure was caused by failure of the low pressure turbine and was uncontained. The reporter said the horizontal stabilizer had a hole in the leading edge about the size of a golf ball.

Title: A CANADAIR CL65 IN CLB AT 3500 FT DECLARED AN EMER AND DIVERTED DUE TO THE R ENG UNCONTAINED LOW PRESSURE TURBINE FAILURE.

Narrative: ON 02/WED/02 AT XA45, FLT XXX DEPARTED THE GATE AT ZZZ BOUND FOR ZZZ1. I WAS THE FO AND PERFORMED THE DUTIES OF PNF ON THIS FLT. WE TOOK OFF ON RWY 29 AT APPROX XA55 ON AN ASSIGNED HDG OF 130 DEGS AND ALT OF 3000 FT. MOMENTS AFTER REACHING OUR ASSIGNED ALT AND HDG, WE WERE GIVEN CLRNC TO CLB TO 13000 FT. THE CAPT BEGAN TO ADVANCE THE THRUST LEVERS AND INITIATED THE CLB. SHORTLY AFTER BEGINNING THE CLBOUT, AT APPROX 3500 FT, A VIBRATION WAS HEARD COMING FROM OUR R (#2) ENG. IMMEDIATELY FOLLOWING THE VIBRATION, A LOUD EXPLOSION TYPE NOISE CAME FROM THE SAME ENG AND WE IMMEDIATELY LOST THE THRUST FROM THE R ENG. I NOTED THAT THE ENG INDICATIONS IMMEDIATELY WENT OUTSIDE OF NORMAL LIMITATIONS AND THE ACFT YAWED. THE CAPT WAS ABLE TO MAINTAIN CTL OF THE ACFT WITHOUT INCIDENT/PROB AND CALLED FOR OUR MEMORY ITEMS TO BE PERFORMED FOR THE EMER CHKLIST FOR ENG FIRE/SEVERE ENG DAMAGE INFLT. I COMPLETED THE CHKLIST AND THE CAPT THEN HAD THE FLT ATTENDANT NOTIFIED OF OUR ENG LOSS AND THAT WE WOULD RETURN THE ACFT TO THE DEP ARPT. I THEN COMPLETED THE APPROPRIATE EMER CHKLIST WHILE THE CAPT FLEW THE ACFT, DECLARED AN EMER WITH ATC, AND COORD OUR RETURN TO THE DEP ARPT. UPON MY COMPLETION OF THE REQUIRED EMER CHKLIST, WE LANDED AT ZZZ WITHOUT FURTHER INCIDENT. UPON LNDG, THE CFR VEHICLES INSPECTED OUR ACFT FOR FIRE/DANGEROUS CONDITIONS ON THE RWY (RWY 29). ONCE THE CFR PERSONNEL COMPLETED THEIR INSPECTION, WE REQUESTED AND WERE APPROVED TO RETURN TO OUR GATE, SINCE THERE WAS NO APPARENT DANGER TO THE ACFT OR PEOPLE/CREW ON BOARD. DURING TAXI BACK TO THE GATE, I CALLED THE STATION PERSONNEL TO INFORM/COORD OUR RETURN AND HAVE THEM NOTIFY DISPATCH/OPS OF OUR SIT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED AFTER PUSHING THE THRUST LEVERS FORWARD A VIBRATION WAS NOTED THEN THE EXPLOSION NOISE. THE AIRPLANE YAWED AND THE ENG INDICATIONS DROPPED TO ZERO. THE RPTR SAID THE AIRPLANE WAS FLOWN BY THE CAPT AND WAS MANAGEABLE. THE RPTR STATED WHEN INSPECTED ON THE GND THE REAR OF THE ENG WAS FOUND EXTENSIVELY DAMAGED AND THE HORIZ STABILIZER HAD A HOLE IN THE LEADING EDGE. CALLBACK CONVERSATION WITH RPTR ACN 539644 REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ENG FAILURE WAS CAUSED BY FAILURE OF THE LOW PRESSURE TURBINE AND WAS UNCONTAINED. THE RPTR SAID THE HORIZ STABILIZER HAD A HOLE IN THE LEADING EDGE ABOUT THE SIZE OF A GOLF BALL.
