Key Takeaways:

Aircraft maintenance can introduce critical errors, as exemplified by a fatal accident where improperly assembled fuel injector nozzles after an annual inspection led to a loss of engine power.
Pilots bear a crucial responsibility to thoroughly verify an aircraft's airworthiness after maintenance, including comprehensive pre-flight checks and test flights, rather than solely relying on mechanic sign-offs.
The accident highlighted failures by both mechanics (improper assembly and inadequate engine run-up check) and pilots (ignoring prior performance issues and failing to abort a takeoff with known engine anomalies).

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.
