Bell 407 and Garmin 430 problem
Maintenance and Garmin are at a loss for a problem with our 430.
If the rotors are turning the Garmin takes 5 mins to find itself and occassionaly it will fail in flight (5 minutes). Replaced the control head 3x, switched connectors, antenna, cables.
Pilots are sure the antenna location may be the problem but Maintenance and Garmin say no.
Another 407 and a 412 have the same problems. We even checked what avionics tech installed the equipment.
Any ideas?
