Narrative:

We were landing on runway 31C at midway. I had briefed the approach including probable taxi route and was planning a right turn off runway 31C. On roll out the tower gave taxi instructions which were 'right turn and back taxi on 13L'. Left stuck in my mind and I thought I heard 'back taxi on 31L.' as I turned left off the runway my co-pilot said he heard a right turn. I said I heard a left turn and he said no more. While back taxiing on 13R/31L the tower said we made the wrong turn. They gave us further taxi instructions. Several things come to mind: towers now give taxi instructions during busy times. Example: on landing roll of short runways with obstacles at end of runway. My co-pilot was 3 months on the airplane, 3 yrs at another airline. He used 'sir' all the time which I should have discouraged. The 'sir' I feel created more unequalness. From clear I know one of my problems is when someone questions a decision is doesn't always raise a red flag in my mind to say stop, let's check that. The assertiveness of my co-pilot plays a big part. I feel the co-pilot being so new blocked his normal assertiveness.

Title: ACR MAKES WRONG DIRECTION TURN AFTER CLRING RWY.

Narrative: WE WERE LNDG ON RWY 31C AT MIDWAY. I HAD BRIEFED THE APCH INCLUDING PROBABLE TAXI RTE AND WAS PLANNING A R TURN OFF RWY 31C. ON ROLL OUT THE TWR GAVE TAXI INSTRUCTIONS WHICH WERE 'R TURN AND BACK TAXI ON 13L'. LEFT STUCK IN MY MIND AND I THOUGHT I HEARD 'BACK TAXI ON 31L.' AS I TURNED L OFF THE RWY MY CO-PLT SAID HE HEARD A RIGHT TURN. I SAID I HEARD A L TURN AND HE SAID NO MORE. WHILE BACK TAXIING ON 13R/31L THE TWR SAID WE MADE THE WRONG TURN. THEY GAVE US FURTHER TAXI INSTRUCTIONS. SEVERAL THINGS COME TO MIND: TWRS NOW GIVE TAXI INSTRUCTIONS DURING BUSY TIMES. EXAMPLE: ON LNDG ROLL OF SHORT RWYS WITH OBSTACLES AT END OF RWY. MY CO-PLT WAS 3 MONTHS ON THE AIRPLANE, 3 YRS AT ANOTHER AIRLINE. HE USED 'SIR' ALL THE TIME WHICH I SHOULD HAVE DISCOURAGED. THE 'SIR' I FEEL CREATED MORE UNEQUALNESS. FROM CLR I KNOW ONE OF MY PROBLEMS IS WHEN SOMEONE QUESTIONS A DECISION IS DOESN'T ALWAYS RAISE A RED FLAG IN MY MIND TO SAY STOP, LET'S CHK THAT. THE ASSERTIVENESS OF MY CO-PLT PLAYS A BIG PART. I FEEL THE CO-PLT BEING SO NEW BLOCKED HIS NORMAL ASSERTIVENESS.
