AMERI-KING AK-450 ELT Installation (FAA TSO C-126)

The ELT installation is noteworthy because it is an FAA requirement, and adding the ELT remote unit to the panel was a time-consuming, delicate process.

 The AK-450 was installed per manual IM-450.  The main unit  was located on right-hand side of tailcone behind the baggage compartment  using Van's bracket P/N F-7129-L.  This location  provides for short coax cable run to a vertical installation (+/- 20 degrees of vertical) just aft of the opened slider canopy.

 Per the manual, we fabricated an .032 doubler in the antennae location and treated it and the bare skin on the inside of the tailcone with MIL-DTL-81706 class 3 (Alodine 600) to provide for corrosion protection and electrical bonding to the required 36-inch diameter ground plane.  This location also provided for the 3- foot clearance from GPS and COMM antennaes required by DYNON.
