A 2 PLT CREW ON A TEST FLT IN A T28 GOT CONFUSED ON WHO WAS FLYING AND DSNDED TO ABOUT 400 FT AGL BEFORE THE RPTR IN THE FRONT SEAT DECIDED TO TAKE CTL OF THE SIT.

Narrative

AFTER THE FBO AT BURLINGTON HAD DONE SOME WORK ON THE INTERCOM SYS; THE SHOP CALLED AND ASKED IF I WOULD TEST FLY THE ACFT; TO SEE IF THE PROB HAD BEEN FIXED. (THE PLT AND THE PERSON IN THE REAR COCKPIT HAVE BEEN HAVING PROBS COMMUNICATING WHILE INFLT.) AFTER TKOF WE FLEW AROUND AND THE NEW HEADSETS AND A REPAIR ON SOME WIRING SEEMED TO FIX SOME OF THE PROB. BUT; IT WAS DECIDED THAT THERE WAS STILL SOMETHING WRONG WITH THE INTERCOM. AFTER 5 MINS OR SO WE HEADED BACK TO BURLINGTON ARPT. I LET THE PLT IN THE REAR COCKPIT FLY THE AIRPLANE BACK TO THE ARPT; AND HE SAID 'I HAVE IT.' WHILE FLYING NEAR THE ARPT HE GAVE ME THE AIRPLANE BACK; BUT I DID NOT HEAR HIM; DUE TO OUR RADIO PROBS. WE WERE ABOUT 1/2 MI W OF THE ARPT DSNDING IN A R TURN AT 400 FT OR SO; AT WHICH POINT I ASKED WHAT HE WAS DOING. HE SAID I THOUGHT YOU WERE FLYING! AT THIS POINT; I TOOK CTL OF THE AIRPLANE; CLBED TO 2000 FT; ENTERED THE PATTERN AT BURLINGTON AND LANDED WITHOUT FURTHER PROBS. I'M NOT SURE HOW LOW WE GOT; BUT IT WAS AROUND 400 FT OR SO.
