Scope; Equipment Description - Garmin GNS 530W Installation Manual

1.2 Scope

The installation instructions and other data contained within this manual are FAA approved under
400W/500W Series AML STC SA01933LA, which is applicable for implementation within airplanes
that are type certificated only under Civil Air Regulation 3 (CAR 3) or 14 Code of Federal Regulations
(CFR) Part 23 (only) into which the Garmin 500W Series unit equipment is qualified for installation and
operational approval. Only the equipment and systems interfaces described in this manual have been
determined to be mutually compatible and are operationally suitable and approved for use as
characterized herein, or within the FAA approved airplane flight manual supplement (AFMS) reflecting
main software version 2.00 and later. Some differences in operation may be observed when comparing
the information in this manual and the FAA approved AFMS to later FAA approved software versions.
Such differences will be identified in revised editions of the FAA approved AFMS characterizing later
software versions, and any applicable limitations and normal or abnormal operating conditions.
It is possible for installers and other appropriately certificated persons to seek FAA approval for
installation and operational use of the 500W Series equipment with systems not identified in this manual,
such as for aircraft certificated under 14 CFR parts 25, 27, or 29, by means of a field approval, STC or
TC. Refer to FAA Advisory Circular (AC) 20-138A and other applicable guidance when applying for
installation and operational approval. AC 21-40 provides guidance for the STC approval process and AC
43-210 provides guidance for the field approval process. If the field approval process is used, it is
advisable to consider the conditions and stipulations in FAA Flight Standards Flight Standards
Information Bulletin for Airworthiness (FSAW), 94-32, "Guidance for Performing Field Approvals of
Installation and Operational Use of Global Positioning Systems (GPS) or GPS with Wide Area
Augmentation Systems (GPS/WAAS), Referred to as Global Navigation Satellite Systems (GNSS)
Equipment", as revised.
Regardless of applicability of the AML STC or alternative application for installation and operational
approval, prior to completing the installation and before returning the airplane to service, the installer or
other appropriately certificated person is required to complete and submit an FAA Form 337 (OMB No.
2120-0020), "Major Repair and Alteration Airframe, Powerplant, Propeller, or Appliance" to their local
FAA Flight Standards District Office describing the work accomplished. The FAA Form 337 must detail
the equipment and systems to which the respective GPS 500W, GNS 530W, or GNS 530AW is
interfaced and reflect appropriately approved or acceptable data for which follow-on FAA field approval
is being sought. See AC 43.9-1E for instructions for completing the FAA Form 337.
