ON A TRAINING FLT WITH A MULTI-ENG STUDENT THE INSTRUCTOR SHUT DOWN AND FEATHERED THE R ENG WHICH WOULD NOT UNFEATHER. A SUCCESSFUL DIVERSION TO A LARGE ARPT AND A SINGLE ENG LNDG WAS MADE.

Narrative

I WAS ON A TRAINING FLT; WORKING WITH A STUDENT ON HER MULTI-ENG RATING IN A PIPER SEMINOLE. AS PART OF THE TRAINING; I USUALLY SHUT DOWN AND FEATHER AN ENG ONCE OR TWICE SO THE STUDENT CAN EXPERIENCE A FEATHERED ENG. WE SHUT DOWN THE L ENG AND SUCCESSFULLY RESTARTED IT. WE THEN CLBED BACK UP TO 9500 FT (LOST ABOUT 500 FT OF ALT ON THE SHUTDOWN) AND I SHUT DOWN THE R ENG AND FEATHERED THE PROP. I WAS UNABLE; AFTER 4 OR 5 TRIES; TO RESTART THE R ENG. WE ORIGINALLY WERE GOING TO LAND AT A SMALL ARPT AND RADIOED THEM FOR A FIELD ADVISORY. THE CONDITIONS AT THAT ARPT WERE NOT AS FAVORABLE AS APA'S SO WE DECIDED TO PROCEED THERE. WE WERE 1/2 WAY BTWN APA AND THE SMALL ARPT. WE CALLED DEN APCH TO EXPLAIN THE SIT AND REQUEST CLRNC THROUGH THE CLASS B. WE WERE GIVEN CLRNC AND PROCEEDED HIGH TO APA WHERE WE SUCCESSFULLY LANDED WITHOUT INCIDENT OR INJURY. THE CTLR EVEN SAID 'NICE LNDG.' MANY CFI'S DO NOT WANT TO FEATHER ENGS DURING MULTI-ENG TRAINING; BUT IT WAS A COOL DAY; WE COULD HOLD ALT AND WE WERE CLOSE TO 2 ARPTS. MY STUDENT LATER COMMENTED THAT SHE WOULDN'T TRADE THAT EXPERIENCE FOR ANYTHING BECAUSE SHE LEARNED THAT ENG FAILURES CAN BE HANDLED WELL. I WILL CONTINUE TO FEATHER ENGS IF THE CONDITIONS ARE APPROPRIATE.
