Just when you think you can't get caught out doing something dumb ...
I thought I'd seen just about every possible combination of dumb tricks, but I managed to surprise myself, this evening.
I have a DB Bi-stormer that is fitted with a towing release. The engine is a pumped OS .91 FS. I'd arranged to meet my mate and tow his Sig Riser.
Whilst setting up, he volunteered to clip the tow line to my model ... and he asked whether he could tip the plane onto its nose so that he would have better access to the loop, which is by the tailwheel.
Having just filled the plane with fuel, I said that I'd plug the fuel vent line so that the precious stuff wouldn't flood out onto the grass... made mental note to remove the plug before flight.
Normally, I prep the tug myself, so I'm intimately involved with the various tasks.
Anyway, I then went off to do something else.
Can you see what's coming, yet?
Of course, the runway was busy, so there was pressure to get hooked up and gone asap.
The aircraft departed normally, climbed crosswind and onto wide downwind, probably a couple of hundred feet agl. Then, engine stuttered.
My first thought was that the engine was overheating, so I reduced power and had the glider unhook. Engine died.
No problem, nice landing ... all safe. Sorry to disappoint you!
I'd forgotten to unblock the fuel vent and the fuel pump eventually lost suction, starving the engine.
Of course, the engine could have quit on take-off, leaving me with nowhere to go except the woods. So, I suppose we were lucky.
The lesson learned is an old one, really. Don't let someone "break" your routine, even though they are trying to be helpful and save time.
