I’ve flown my share of first flights after maintenance. Most went well; some didn’t. My first bad experience involved retrieving a Piper PA-28-181 Archer II from a scheduled inspection. The run-up and takeoff were nominal. Soon after, ATC reported my transponder wasn’t working and gave me identifying vectors before I flew around the Bravo between me and the destination.
Once parked on the ramp, I pulled the mixture to idle cutoff and…nothing happened. I shut it off with the magneto switch (when I should have just turned off the fuel valve). Turned out the transponder’s spike antenna on the belly had been snapped off, and the mixture control linkage wasn’t connected.
