AN ACR MLG RAN OFF THE END OF THE RWY AFTER LOSING A THRUST REVERSER AND ALL BRAKES. AFTER RETURN/LAND DUE TO SUSPECTED ENG FAILURE.

Narrative

AFTER THE CAPT'S PRE-TKOF BRIEF. WE TOOK OFF ON RWY 35L AT DEN. PWR AND ALL CALLOUTS WERE NORMAL UNTIL THE 'POSITIVE RATE; GEAR UP' CALL. WHEN I PUT THE GEAR UP; WE HEARD A 'BANG!' VIBRATION SHOOK THE ACFT. A ROLL AND YAW INTO THE R ENG FOLLOWED AT BTWN 100-200 FT AGL. THE CAPT ASKED WHICH ONE IS IT? AND I STATED 'THE R ONE.' CAPT CALLED 'IGNITION OVERRIDE; CHK FUEL SYS.' WE CLBED TO ABOUT 6000 FT MSL AND BEGAN TO RUN THE CHKLIST FOR AN ENG FAILURE. THE ENG (R) WAS DEVELOPING PWR; BUT AT A REDUCED RATE. WE WENT THROUGH THE ENG FAILURE CHKLIST AND SINGLE ENG IN-RANGE LNDG. MAX ALT WAS 7200 FT MSL. AFTER LNDG; BRAKING AND L ENG THRUST REVERSE WAS NORMAL (AS ALL HYD SYS FUNCTIONS) UNTIL BRAKING WAS NEEDED AT END OF RWY. WE HAD NO HYD PWR TO THE BRAKES (THE ACCUMULATOR CHARGE WAS GONE). WE ROLLED OFF THE END OF THE RWY AT A LOW SPD AND THE ACFT CAME TO REST SHORT OF A TXWY. WE DID NOT KNOW WE HAD LOST HYD PRESSURE FOR THERE WAS NO ANNUNCIATOR LIGHT. THE THRUST REVERSER OF THE R ENG HAD FALLEN OFF TEARING OUT WIRING AND HYD LINES. WITH NO WARNING(S) WE DID NOT HAVE THE CLUES FOR ADDITIONAL FAILURES. FURTHER; WE DID NOT KNOW THAT THE THRUST REVERSER HAD FALLEN OFF SO; WITHOUT THAT AIRBORNE INFO; WE COULDN'T DETERMINE WHAT WAS WRONG. WE WENT ON INFO AT HAND. LOSS OF THRUST REVERSER R ENG. LOSS OF HYD FLUID DUE TO LINES BEING EXPOSED. LOSS OF BRAKES DUE TO ABOVE CIRCUMSTANCES. SUPPLEMENTAL INFO FROM ACN 230445: A FLASH OF THE MASTER CAUTION FOR APPROX 1 SEC FOLLOWED BY A FLASH OF THE R REVERSE UNLOCK LIGHT WERE THE ONLY COCKPIT INDICATIONS THAT WE GOT. THE BRAKES FAILED AT 80 KTS. WE DEPARTED THE RWY AT THE DEP END TO THE L TO AVOID A FENCE. WE DID A 180 DEG TURN USING REVERSE THRUST FROM THE L ENG. THE L MAIN GEAR SUNK IN A DITCH WHICH STOPPED THE ACFT.
