D 190-00357-021.2 ScopeThe installation instructions and other data contained within this manual are FAA approved under400W/500W Series AML STC SA01933LA, which is applicable for implementation within airplanesthat 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 andoperational approval. Only the equipment and systems interfaces described in this manual have beendetermined to be mutually compatible and are operationally suitable and approved for use ascharacterized herein, or within the FAA approved airplane flight manual supplement (AFMS) reflectingmain software version 2.00 and later. Some differences in operation may be observed when comparingthe 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 latersoftware 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 forinstallation 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 orTC. Refer to FAA Advisory Circular (AC) 20-138A and other applicable guidance when applying forinstallation and operational approval. AC 21-40 provides guidance for the STC approval process and AC43-210 provides guidance for the field approval process. If the field approval process is used, it isadvisable to consider the conditions and stipulations in FAA Flight Standards Flight StandardsInformation Bulletin for Airworthiness (FSAW), 94-32, “Guidance for Performing Field Approvals ofInstallation and Operational Use of Global Positioning Systems (GPS) or GPS with Wide AreaAugmentation 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 operationalapproval, prior to completing the installation and before returning the airplane to service, the installer orother 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 localFAA Flight Standards District Office describing the work accomplished. The FAA Form 337 must detailthe equipment and systems to which the respective GPS 500W, GNS 530W, or GNS 530AW isinterfaced and reflect appropriately approved or acceptable data for which follow-on FAA field approvalis being sought. See AC 43.9-1E for instructions for completing the FAA Form 337.1.3 Equipment DescriptionThe 500W Series units are 6.25 inches wide and 4.60 inches high. The display is a 320 by 234 pixelcolor LCD.
