Did the plane just have an inspection? [...]

Define "just". It did recently come out of its annual inspection.
However,
it'd had four flights already since the inspection and before the flight
on
which this happened.

Ah, then I guess not. It's just the first time I start the engine after the
annual that it happens on my plane.

Just an idea.
