9.3 ICA for Trig TY91/92 Radio:
Other than for periodic functional checks required by the regulations, the TY91/TY92 VHF radio has
been designed and manufactured to allow “on condition maintenance”. This means that there are no peri-
odic service requirements necessary to maintain continued airworthiness, and no maintenance is required
until the equipment does not properly perform its intended function. When service is required, a complete
performance test should be accomplished following any repair action. Repairs should only be carried out
in accordance with Trig Avionics Limited service procedures.
