Stc Applicability - Garmin GI 275 Installation Manual

1.1 STC Applicability

This manual defines aircraft modifications required to install the GI 275 Multi-Function Instrument under
the GI 275 Part 23 AML STC. It is only applicable to aircraft models listed on the Approved Model List.
Aircraft modifications per this STC involve the installation of components and LRUs specified in the STC
Equipment List, which include sensors common for engine parameters. Installation of components and
LRUs not included in the STC Equipment List require a separate airworthiness approval.
The GI 275 Multi-Function Instrument is approved for installation in Class I-IV aircraft, with certain
limitations; refer to Section 2.
Applicability of this STC for a particular aircraft must be verified before the modification based on the data
contained in this manual. Some aircraft may have been modified or equipped with systems in which the
GI 275 interface is not defined nor approved. The installer must make the final determination if this STC is
applicable to a given aircraft.
The installation of the GI 275 Multi-Function Instrument in accordance with this STC is a major alteration
to the aircraft. Following a major alteration, the aircraft must be returned to service in a means acceptable
to the cognizant aviation authority. An example would be compliance with 14 CFR 43.9, 14 CFR 91.417,
and submission of an FAA Form 337 "Major Repair and Alteration Airframe, Powerplant, Propeller, or
Appliance" completed in accordance with AC43.9-1F Instructions for Completion of FAA Form 337.
Consistent with FAA Order 8110.4B and AC 21-40, a permission letter to use this STC data is available for
download from the Garmin Dealer Resource Center.
