Greetings from Dogpatch, USA. Well the GPAA had it's 20 year tank inspection at 3MY today. A contractor pumped all the fuel out into a tanker trailer parked at the pumps and put a man into the tank for the inspection. After he was done, he setup a temporary pump from the tanker. First customer: the on base flight school's champ. Put 6 gallons in the header tank, student took an inch from the fuel drain (I did not see the sample), started it up; upon throttle advance it coughed and sputtered and died. Into the shop. Probably 4 of the gallons were water. Did the contractor have water in the bottom of his tank? Our staff had done the morning bottom sample of the tank, and it was signed off (and I'm pretty sure it actually was done). EVERYONE in the chain was lucky: The pilot, the CFI, the FBO, the Tank inspection contractor, the Greater Peoria Airport Authority. I had eyeballed the situation at 2:00 PM and chose instead to go to CTK for 52 g of fuel. When I returned, EVERYONE was in the shop. THE only damages here are mechanic time and the flightschool being down, as there is no "good" avgas on the field and it's notamed as such. Peoria IL (Mount Hawley Auxiliary) [3MY]: December NOTAM #48 issued by Kankakee IL [IKK] Service(s) fuel not available effective from December 12th, 2012 at 04:16 PM CST (1212122216) - December 14th, 2012 at 05:00 PM CST (1212142300) But the Director of the Authority clearly tried to save the 2.5 thousand $$ fees to bring Avfuel trucks onto the airport for fueling needs in the interim. This could have been really bad, but fortunately did NOT turn out that way. Bad move, by the Airport Authority. Always take enough of a sample to driain the line. Never buy fuel in tne non-normal condition. Why do I live in Dogpatch?
