Compliance is required as indicated unless already accomplished to prevent disruption of radio communication.

(a) Within the next 10 hours time in service after the effective date of this AD, comply with the following:

(1) Locate the audio adapter connector in the main radio harness behind the radio stack. This is the interconnect for individual radios in the audio selector panel.

(2) Locate the muting relay plug in this connector. It is a three (3) pin plug containing wires ASP-1, ASP-2, and ASP-3 and is positioned at one end of the adapter connector.

(3) Disconnect the muting relay plug and attach securely to the harness in accordance with Advisory Circular AC43.13-1A.

(4) Conduct complete operational check of all radios.

(5) Make a maintenance record entry.

(b) Within the next 100 hours time in service after the effective date of this AD, comply with the following:

(1) On PA-32-260, PA-32-3O0, PA-32-301, PA-32-301T, PA-32R-300, PA- 32RT-300, PA-32RT-300T, PA-32R-301, PA-32R-301T and PA-34-200T model aircraft gain access by removing four (4) screws from the speaker grille ring. On all other affected models, gain access by lowering the overhead dome panel.

(2) Remove the 22 mfd capacitor, part number 454-045, soldered to the muting relay, noting polarity, and install diode as shown in figure 1. Diode is not required on Bendix avionics systems.

(3) Reconnect the muting relay plug and conduct radio check for proper operation.

(4) Make a maintenance record entry.
