STC ST02089AT is for installation of a unit to provide GPS position source. This STC includes
installation of a GPS antenna on a model B747-100. The antenna is installed to just off the upper
centerline of the fuselage pressure vessel at STA 650 and a coax connector protrudes through a
0.813 inch diameter, reinforced hole. The DTA data for this STC was approved when the STC
was initially issued.
STC SA00328SE is an AML STC that includes two models, the Part 23 Partenavia, and the CAR
4b model B727 Series aircraft. (The Partenavia is a Part 23 aircraft and is therefore not covered
by this Part 26 FCAS data.) The model B727 series aircraft has two antennas installed just offcenter of the upper center line at STA 429 and STA 450 and a coax connector protrudes through
a 0.50 inch diameter reinforced hole.
STC SA5904NM is an AML STC that includes two models, the Part 23 Partenavia, and the CAR
4b model B727 Series aircraft. (The Partenavia is a Part 23 aircraft and is therefore not covered
by this Part 26 FCAS data.) The model B727 series aircraft has two antennas installed just offcenter of the upper center line at STA 429 and STA 450 and a coax connector protrudes through
a 0.50 inch diameter reinforced hole.
