Narrative:

While descending from FL240 to 15000 ft our flight crew was avoiding a small area of green to yellow intensity on the aircraft radar. Abeam this area we experienced communication failure due to the aircraft receiving all possible navigation and communication reception at maximum volume. Shortly thereafter our flight crew smelled burning electrical wires so we compiled with the electrical odor checklist. With no relief of our communication problem we deactivated the #1 audio panel circuit breaker and reestablished communication with casper approach control. The flight then landed without further incident.

Original NASA ASRS Text

Title: DO328 WITH COM LOSS AND FUMES REESTABLISHES RADIO CONTACT WITH CPR AND LANDS WITHOUT FURTHER INCIDENT.

Narrative: WHILE DSNDING FROM FL240 TO 15000 FT OUR FLC WAS AVOIDING A SMALL AREA OF GREEN TO YELLOW INTENSITY ON THE ACFT RADAR. ABEAM THIS AREA WE EXPERIENCED COM FAILURE DUE TO THE ACFT RECEIVING ALL POSSIBLE NAV AND COM RECEPTION AT MAX VOLUME. SHORTLY THEREAFTER OUR FLC SMELLED BURNING ELECTRICAL WIRES SO WE COMPILED WITH THE ELECTRICAL ODOR CHKLIST. WITH NO RELIEF OF OUR COM PROB WE DEACTIVATED THE #1 AUDIO PANEL CIRCUIT BREAKER AND REESTABLISHED COM WITH CASPER APCH CTL. THE FLT THEN LANDED WITHOUT FURTHER INCIDENT.
