Garmin Transponder woes

[GAHorn]

On September 10, 2003 the FAA issued an Airworthiness Concern Sheet
(ACS) after receiving reports that certain TCAS 1, TAS, and TCAD
systems may not display the position of a GTX 330/330D transponder
equipped aircraft. The affected Garmin GTX 330 part numbers are 011-
00455-00 and 011-00455-20 and the GTX 330D part numbers are 011-00455-
10 and 011-00455-30. There is a 30 day response time line with comments
due by 10/20/2003. Full text of the ACS can be seen at:

Garmin has already addressed this concern in Service
Bulletin 0304 Rev. B. which can be seen at:
