A.1

Continued Airworthiness

This section provides assistance to the installing agency in preparing Instructions for Continued
Airworthiness (ICA) in response to Bulletin Number HBAW 98-18, "Checklist for Instructions for
Continued Airworthiness for Major Alterations Approved Under the Field Approval Process", effective
10/7/98.
Aviation Authority approved installers are hereby granted permission to reference appropriate service
instructions and excerpts from this Installation Manual to accomplish the Instructions for Continued
Airworthiness. This permission does not construe suitability of the documents. It is the applicant's
responsibility to determine the suitability of the documents for the ICA.
Following is a suggested ICA for a Garmin 400 Series unit installation. Some of the checklist items do not
apply, in which case they should be marked "N/A" (Not Applicable). In this sample, square braces are
used to indicate instances where explicit words should be substituted (e.g., replace "[400 Series unit]" with
"GNS 430").
