The before and after on an old 737 radio stack I worked up last month
I got a call to look at a radio stack from a 737 that was acting up during approach. The before picture was a mess, wiring was all tangled up and one connector was barely hanging on. After about 6 hours of tracing wires and cleaning contacts, I got it sorted. The after was night and day, the traffic collision system stopped throwing false alerts and the comms were crystal clear. The pilot told me it was the first time in months that approach didn't have to repeat themselves. Has anyone else run into a stack that looked fine but had broken ground pins hiding behind the panel?
