We had a little drama at the airport on Saturday. I had just landed when I watched this whole thing play out.
I was on the taxiway listening to a Piper Cherokee making radio calls. Apparently he wanted to make an 'expedited' landing with an airsick passenger. This Piper was trying to break in somewhere on a non-standard right base instead of flying the pattern in. There was a steady stream of traffic landing on 35. He tried to get a Skywagon on final to break off and let him land. The Skywagon kept telling the Piper 'it ain't going to work for me'! The Piper jumped in front of the Skywagon anyway, cutting in front of him by no more than 300 ft. The Piper made a short right base, turned final over the fence and skittered far enough down the runway for the Skywagon to make a landing. The Skywagon just made it over the fence, rolled out a few hundred feet and turned off into the grass. The prop had stopped, the door popped open and I thought 'this is it, the Piper driver's gonna catch it now'. I put my plane in the hanger and made my way back to see what happened.
It turns out that the reason why the Skywagon wasn't going to break off and let this Piper in is because he was out of fuel. The engine was sputtering and quit just as he crossed the fence. About fifteen minutes later Wagon Driver finished topping off the tanks when it all became quite clear. The 'Wagon Driver had calculated 58-1/2 useable based on the book but somehow that had changed. He just filled both tanks and couldn't get them to take anymore than 52 gal. Apparently, when he changed the tank bladders several years ago, they must not have stretched out to the full volume of the tank. Now the question: How many times was he on fumes and never knew it. The six gallons he didn't have was the legal minimum that should have been in the tank!
