eplacement of all C-5B tie box fittings as soon as possible through PDM. To mitigate the risk<br />
during the replacement program, AMC has implemented a tie box inspection during isochronal (ISO)<br />
inspection. <strong>The</strong> same procedures that were used for A-model replacement are applicable for B-model<br />
replacement. <strong>The</strong> new tie boxes are made of 7049-T73, a material more resistant to SCC.<br />
Emergency Power System Upgrade<br />
C-5 emergency direct current power system upgrade provides increased electrical capacity for<br />
emergency use. <strong>The</strong> current system is the original system designed 40 years ago. Load analysis<br />
indicates DC power buses exceed emergency generator capacity and might exceed capacity by ~ 25<br />
amps with the C-5 AMP installation. This initiative replaces the current system (3 kilovolt-ampere<br />
[KVA] generator and two 5 amp-hour batteries) with a new 6.5 KVA militarized, off-the-shelf generator<br />
and one 54 amp-hour battery. <strong>The</strong> upgrade also adds two new 100-amp regulated transformer rectifier<br />
units and a battery charging system, and modifies the flight engineer’s direct current control panel.<br />
