AD: Becker Flugfunkwerk GmbHAR

AD NUMBER: 2004-21-04
MANUFACTURER: VHF AM Transceivers
SUBJECT: Airworthiness Directive 2004-21-04
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Becker Flugfunkwerk GmbHAR 4201 VHF AM transceivers. This AD requires adding an aircraft flight manual (AFM) limitation to the Limitations Section of the AFM, and cockpit placard due to the intermittent malfunctioning of the transceiver, or removing the affected transceiver from service. This AD results from reports of crewmembers having difficulty communicating with Air Traffic Control and other aircraft due to the AR 4201 VHF AM transceiver's inability to block interference from transmitters operating on frequencies other than those set in the transceiver. We are issuing this AD to prevent difficulty in communicating with Air Traffic Control and other aircraft due to intermittent malfunctioning of the transceiver.
