190-02246-10 GI 275 Part 23 AML STC Installation Manual
Rev. 11 Page 3-4
3.1.2 Commercial
The GI 275 equipment is designed to be installed using standard commercially available parts and
accessories. The following may be required for the installations:
1. Display backup switch comprised of MS27719-22-1 miniature toggle switch and Aircraft Spruce
P/N 11-00815 red toggle switch cover.
2. MS26574 or MS22073 push-pull manually resettable circuit breakers or other trip-free, push-pull
circuit breaker type as specified in the aircraft manufacturer’s parts catalog.
3. MIL-W-22759/16 or MIL-W-22759/18 electrical wire.
NOTE
MIL-W-22759/18 wire is recommended due to the insulation diameter being more
compatible with high-density connectors.
4. MIL-C-27500 shielded cable with M22759/16 wire (TE) or M22759/18 wire (TG) and ETFE
jacket (14).
5. MS25036 or MS20659 ring terminals.
6. M83519/2-X shield terminators.
7. A-A-59163 (MIL-I-46852C) silicone fusion tape.Wire bundle routing, securing, and management
supplies, as required.
8. 2024-T3 aluminum per AMS-QQ-A-250/5, or 6061-T6 aluminum per AMS 4025, AMS 4027, or
AMS-QQ-A-250/11, varying thickness.
9. Line and fittings, including 1/8-27ANPT male fitting for pitot and static connection and pneumatic
line. Refer to aircraft-specific parts catalog for approved pitot and static connector part numbers.
10. TSO-C53a Type C or D hose (e.g., Aeroquip 303 hose with AE102 sleeve and 900591B clamps or
Aeroquip AE466) for installation of fuel flow transducers and pressure sensors.
11. 22 or 24 AWG stranded thermocouple extension wire to match K-Type or J-Type probe, with a
minimum continuous temperature rating of 400 °F and ASTM E230 Standard Limits or NIST ITS
90 electrical qualifications (e.g., Watlow SERV-RITE P/Ns K24-3-507 and J24-3-507).
12. Ethernet cable, aircraft grade category 5 (required only for HSDB interfaces). Only Ethernet
cables listed in Table 3-5 can be used. 24 AWG is preferred.
Table 3-5 HSDB Cables
Notes:
[1] E10422 cable is not recommended because of the larger insulation diameter,
making it very hard to work with in the high density connectors. E1042x cable is
also not recommended due to insulation shrinkage that can occur.
