The rebuild of ZA326 took a big step forward this month with the reinstatement of the AC ground power socket. When the aircraft was retired from service in 2005 the socket (and some of the loom!) was cut out, meaning a re-wiring job for Swanny.
With the new socket installed and connected it was time to try applying power to the aircraft for the first time in over a decade. We pressed the button and….. nothing!
As you might expect with an aircraft as complex as the Tornado, nothing is a simple fix. We suspect that the fault may lie with a little black box called the Ground Power Control Unit (or GPCU for short). This contains some fail-safe logic which protects the aircraft in the event that unsuitable power is applied.
We will overhaul the GPCU and try again when the weather improves…
