9.
Continued Airworthiness
22 June 2017
Issue AE
Other than for periodic functional checks required by the regulations, the TY96/TY97 VHF radio has been designed and manufactured to allow “on condition maintenance”. This means that there are no periodic 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.
9.1 Cleaning the Front Panel
The plastic body and switches should be cleaned with a soft cotton cloth moistened with clean water.
The LCD screen should be lightly cleaned with a lint free cloth taking care not to scratch the surface.
