PLT AND PAX ABOARD SR20 COMBINE FORCES TO EFFECT A SAFE EMER LNDG AFTER A COMPLETE ENG FAILURE.

Narrative

DURING THE FLT FROM ZZZ1 TO ZZZ2 WHEN WE WERE ALMOST ABEAM ZZZ THERE WAS A LOUD 'BANG' IN THE AIRPLANE AND THE OIL PRESSURE WENT IMMEDIATELY TO ZERO. OIL PRESSURE WAS NORMAL THROUGHOUT THE FLT UNTIL THE ENG FAILURE. BEFORE THE ENG FAILURE; WE HAD BEEN CRUISING AT 10000 FT. PER ATC REQUEST; WE EXECUTED A SLOW ASCENT TO 11000 FT. AFTER LEVELING OFF AT 11000 FT; WE LEANED THE ENG TO BEST PWR AT 2700 RPM AND CONTINUED THE CRUISE TOWARD ZZZ2. THE ENG FAILED ABRUPTLY; WITH NO WARNING SIGNS NOTED IN THE AIRPLANE INSTRUMENTATION. AFTER THE FAILURE; THE ENG APPEARED TO BE PRODUCING NO PWR AT ALL; THE PROP WAS WINDMILLING AT 2700 RPM; AND AN IMMEDIATE DSCNT WAS INITIATED. I ADVISED CTR THAT WE HAD LOST PWR AND WERE VACATING THE ALT. WE DECLARED AN EMER; COMPLIED WITH ATC REQUESTED INFO; ADVISED THAT WE HAD ZZZ IN SIGHT AND WITHIN GLIDING RANGE AND INTENDED TO MAKE A DEAD STICK LNDG AT THE ARPT. THE PF FLEW THE DSCNT WHILE I PROVIDED ARPT INFO FROM THE GARMIN 430 DATABASE. WE DISCUSSED THE SIT AND DECIDED TO SECURE THE ENG. HE PULLED THE MIXTURE FULL LEAN; AND I SHUT OFF THE FUEL. THE PF MANEUVERED THE AIRPLANE TO A TOUCHDOWN ON THE GRASS RWY ADJACENT TO THE PAVED RWY AND MADE A SMOOTH TOUCHDOWN. THE AIRPLANE COASTED TO A STOP ON THE PARKING TARMAC. THE PROP WAS WINDMILLING THROUGHOUT THE DSCNT AND LNDG. BORESCOPE INSPECTION REVEALED THAT ONE OF THE PISTONS WAS NOT MOVING WITH THE PROP; AND WE CONCLUDED THAT THERE WAS EVIDENCE OF A BROKEN CONNECTING ROD. SUPPLEMENTAL INFO FROM ACN 626437: THE DSCNT RATES WERE SOMEWHAT HIGHER THAN EXPECTED; PROBABLY BECAUSE OF THE DRAG OF THE WINDMILLING PROP. AS WE GOT CLOSE TO THE ARPT I FELT THAT WE WERE A BIT HIGH. I LOWERED THE FLAPS AND CONTINUED TOWARD THE MAIN RWY. IN MY JUDGEMENT WE WERE NOW AIMED TO TOUCHDOWN ABOUT 2/3 OF THE WAY DOWN THE RWY. NOT WANTING TO TAKE A CHANCE ON RUNNING OFF THE FAR END; I ELECTED TO MAKE ONE MORE 5-TURN. I RAISED THE FLAPS AND TURNED ABOUT 40 DEGS TO THE R; THEN BACK TOWARD THE RWY. NOW IT SEEMED THAT WE WERE TOO LOW TO REACH THE PAVED RWY; SO I TOLD COPLT WE WOULD LAND ON THE GROOMED GRASS RWY THAT PARALLELS THE PAVED RWY. BOTH CREW MEMBERS USED OXYGEN THROUGHOUT THE FLT USING CANNULA DEVICES.
