Narrative:
On climb out captain was flying aircraft. First officer handling communications when first officer audio panel failed. While transitioning communications to captain and flying duties to first officer we were given turn to intercept 196 degree radial for clt VOR. As a result of confusion during duties shift we did not understand that we were to intercept 196 degree radial. No conflict resulted, but we failed to intercept the radial. Callback conversation with reporter revealed the following information: the reporter stated he was flying the MD80. He stated that the radio got silent for a while before they noticed there was a problem with the first officer audio panel. During that time on the 120 degree vector they crossed the 196 degree radial instead of intercepting it.
Original NASA ASRS Text
Title: THE FLC LOST THE FO AUDIO SELECTOR PANEL. THE FO TURNED OVER THE RADIO DUTIES TO THE CAPT. DURING THE CONFUSION THE PF DID NOT INTERCEPT THE ASSIGNED CLT RADIAL.
Narrative: ON CLBOUT CAPT WAS FLYING ACFT. FO HANDLING COMS WHEN FO AUDIO PANEL FAILED. WHILE TRANSITIONING COMS TO CAPT AND FLYING DUTIES TO FO WE WERE GIVEN TURN TO INTERCEPT 196 DEG RADIAL FOR CLT VOR. AS A RESULT OF CONFUSION DURING DUTIES SHIFT WE DID NOT UNDERSTAND THAT WE WERE TO INTERCEPT 196 DEG RADIAL. NO CONFLICT RESULTED, BUT WE FAILED TO INTERCEPT THE RADIAL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED HE WAS FLYING THE MD80. HE STATED THAT THE RADIO GOT SILENT FOR A WHILE BEFORE THEY NOTICED THERE WAS A PROB WITH THE FO AUDIO PANEL. DURING THAT TIME ON THE 120 DEG VECTOR THEY CROSSED THE 196 DEG RADIAL INSTEAD OF INTERCEPTING IT.
