Narrative:

Was giving BFR, biannual flight review, demonstrating proper use of newly installed spoilers for descent. Tower cleared flight to land with a left base entry for runway 19. There was no push to talk button on my yoke and the hand microphone was unplugged. Aircraft owner was flying left seat and working radio. He entered left downwind instead of left base, causing tower to ask him to call them upon landing. Airport was unfamiliar to aircraft owner. The downwind entry was used in order to lose altitude, and communication was lost shortly after landing clearance was received. I should have supervised student more closely and carried my hand-held transceiver. Never assume that because a biannual flight review is being given to an experienced pilot in a complex pressurized high performance reciprocating twin that the owner won't get stupid on you. In the future I will instruct as if every student is trying to kill me or get me violated. This incident/episode happened/developed so quickly that there was no time to take over control of the aircraft. A contributing factor was the left (#1) engine had blown an induction elbow and was normally aspirated. This happened en route. No big deal to me, but it rattled/distracted the aircraft owner.

Title: INSTRUCTOR PIREP OF A BIANNUAL FLT REVIEW ON A TWIN SMT AND HOW THINGS CAN GET OUT OF HAND, QUICKLY. PLT OF SMT FAILED TO MAKE A L BASE LEG ENTRY AT ACT AND TWR WANTED A CALL WHEN ON THE GND.

Narrative: WAS GIVING BFR, BIANNUAL FLT REVIEW, DEMONSTRATING PROPER USE OF NEWLY INSTALLED SPOILERS FOR DSCNT. TWR CLRED FLT TO LAND WITH A L BASE ENTRY FOR RWY 19. THERE WAS NO PUSH TO TALK BUTTON ON MY YOKE AND THE HAND MIKE WAS UNPLUGGED. ACFT OWNER WAS FLYING L SEAT AND WORKING RADIO. HE ENTERED L DOWNWIND INSTEAD OF L BASE, CAUSING TWR TO ASK HIM TO CALL THEM UPON LNDG. ARPT WAS UNFAMILIAR TO ACFT OWNER. THE DOWNWIND ENTRY WAS USED IN ORDER TO LOSE ALT, AND COM WAS LOST SHORTLY AFTER LNDG CLRNC WAS RECEIVED. I SHOULD HAVE SUPERVISED STUDENT MORE CLOSELY AND CARRIED MY HAND-HELD TRANSCEIVER. NEVER ASSUME THAT BECAUSE A BIANNUAL FLT REVIEW IS BEING GIVEN TO AN EXPERIENCED PLT IN A COMPLEX PRESSURIZED HIGH PERFORMANCE RECIPROCATING TWIN THAT THE OWNER WON'T GET STUPID ON YOU. IN THE FUTURE I WILL INSTRUCT AS IF EVERY STUDENT IS TRYING TO KILL ME OR GET ME VIOLATED. THIS INCIDENT/EPISODE HAPPENED/DEVELOPED SO QUICKLY THAT THERE WAS NO TIME TO TAKE OVER CTL OF THE ACFT. A CONTRIBUTING FACTOR WAS THE L (#1) ENG HAD BLOWN AN INDUCTION ELBOW AND WAS NORMALLY ASPIRATED. THIS HAPPENED ENRTE. NO BIG DEAL TO ME, BUT IT RATTLED/DISTRACTED THE ACFT OWNER.
