One of the things needed for the inspection is a fuel flow test and, looking through the inspection checklist I was given, a compression test.<\/p>\n

The compression test is supposed to be what they call a differential test where you have two gauges and a bunch of other stuff to take the reading but all I had access to was a standard static compression tester so that will have to do. Oh, and by access to, I meant go out an buy from the local auto emporium.<\/p>\n

Its a brand new engine, purrs like a kitten, we know the cylinders are good. Sure enough everything was in the 170s which is at the top end of ok per the Rotax maintenance manual.<\/p>\n

For the fuel flow test, we disconnected the fuel line just before the engine fuel pump and timed how long it took for 3 gallons of fuel to flow from each tank and out the line into a fuel can. Some simple math will then give the gallons per hour that the electric fuel pump is putting out. Scott was on hose duty while I took care of the stopwatch. <\/p>\n

\"Fuel<\/a><\/p>\n

Each tank came out at around 26 gph which is way above the FAA requirement of 125% of the engine max fuel flow which would be 10.25 gph.<\/p>\n

From here I’m gathering the initial documentation to send to the inpsector.<\/p>\n","protected":false},"excerpt":{"rendered":"
