Section 2.0 Installation
2.1 Introduction
Information in this section consists of: unpacking and inspection procedures, installation

2.2 Unpacking and Inspection
Unpack the equipment carefully and locate the warranty card. Inspect the unit visually
for damage due to shipping and report all such claims immediately to the carrier
involved. Note that each unit should have the following:
- AA20-431 Cabin PA System
- Warranty Card
- Operator’s Manual

Verify that all items are present before proceeding and report any shortage immediately
to your supplier.
2.2.1
Warranty
Complete the warranty card information and send it to NAT when the installation is
complete. If you fail to complete the warranty card, the warranty will be activated on
date of shipment from NAT.
Note: An appropriately rated facility, e.g. Certified Aircraft Repair Station, must install this
equipment in accordance with applicable regulations. NAT Ltd’s warranty is not
valid unless the equipment is installed by an authorized NAT Dealer. Failure to
follow any of the installation instructions, or installation by a non-certified individual
or agency will void the warranty, and may result in a non-airworthy installation.
2.3 Installation Procedures
2.3.1 Note to Installers
The AA20-431 is intended for use as a cockpit-mounted control for an internal or
external aircraft PA system, where such a system is not installed to fulfill the
airworthiness requirements for the aircraft or an operating rule.
The AA20-431 is certified to RTCA DO-160C Section 20 (RF Susceptibility) Category T,
for installation in a well-protected electromagnetic environment such as an enclosed
avionics bay in an all-metallic aircraft. The equipment shall therefore not be installed to
satisfy the requirement of FAR 25.1423 for a Public Address system.
