A few of these lately have been soon after leaving the ground, hardly a chance to ‘circle the airport’.
Yes, could be about anything, but certain instances call for the thorough preflight, then extended ground checks. With some checks & evaluation, may not even leave the ground.
A few years ago I had an issue I wanted to evaluate, along the lines of an earlier, possibly, partially obstructed fuel injector. After the inspection & cleaning, part included an extended, full power ground run. Some reasoning included a stable, full power run, longer than a normal takeoff period. Yes, I watched temps, prop wash & FOD concerns.
There may of been that distant hangar neighbor wondering, ‘what’s that fool doing over there’? Anyway, things checked & have been fine since.
I’m reminded of the ‘drive like you stole it’ sticker, or the ‘Italian tune-up’.
