RPTR IN A HOMEBUILT RV TRIES TO GET ANOTHER RV TO PLAY WITH HIM; UNAWARE THE PLT OF THE SECOND RV IS RECEIVING AN FAA CHK RIDE.

Narrative

FRIDAY AFTERNOON; DECIDED TO TAKE ACFT FOR A FLT (TGIF). WHILE MONITORING UNICOM; HEARD THE CALL NUMBERS OF A SIMILAR ACFT BASED AT THE LCL ARPT. BUBBLING WITH ENTHUSIASM; I INITIATED RADIO CALL; 'RV ON DOWNWIND; WHY DON'T YOU TURN OUT OVER THE LAKE' HOPING FOR SOME AIR-TO- AIR COMPANIONSHIP. IN THE NEXT FEW MINS SEVERAL EVENTS OCCURRED. THE ACFT I CALLED DID TURN OUT OF THE PATTERN AND HEADED OVER THE LAKE. I HEARD BUT DID NOT LINK TO THE SIT A RADIO XMISSION; 'RV PLEASE STAY CLR I AM GIVING AN INST CHK RIDE.' INTERPRETING THE TURNOUT OF THE PATTERN AS AN INVITATION; I MANEUVERED MY ACFT TO PULL ALONGSIDE HIS. IN THE PROCESS OF DOING THIS I RECEIVED HAND SIGNALS DIRECTING ME TO TURN AWAY. THIS I DID WITH NO DELAY REALIZING I HAD MANEUVERED ALONGSIDE A FRIEND RECEIVING A FLT CHK AND THAT THE REQUEST TO STAY CLR HAD BEEN DIRECTED AT ME; AND I HAD UNINTENTIONALLY DISREGARDED IT. I'M SURE THE EXAMINER WAS FURIOUS. I CALLED THE OTHER PLT WITHIN THE HR TO APOLOGIZE AND IN THIS CASE TO CONGRATULATE HIM ON A NEW RATING. A LESSON LEARNED! 22 YRS; 10300 HRS; NO ACCIDENTS OR INCIDENTS -- BUT STILL TRYING TO LEARN HOW TO PREVENT SLIPS LIKE THIS.
