Sorry for the delay in updating this thread after the jetcal run. We're getting very close to bringing the Skyhawk home under it's own power. I'll update what we have to finish after updating how the engine run went. A big thank you to Scott, Ben and Josh for doing the run for us. It did make things go faster which was a plus due to the nice fall weather we had.
Sean and I had the airplane outside fueled and ready to go for the run when the guys showed up.
After checking the throttle rigging and setting up the Jetcal we attempted an engine start, but had no engine rotation. I guess it is kind of funny now, but at the time it was a little frustrating. We needed to get this run done as we brought the crew up from Texas to do this. Time to troubleshoot the starter probe. It was spinning the air turbine, but not the shaft that connects to the engine. We were pretty sure we sheared the splines, but didn't know where they were located exactly. It seemed like eternity as we searched for the spline adapter. Always seems that way when you put the pressure on yourself. We finally found them and sure enough it had sheared.
We were lucky enough to have a spare attached to the starter probe and were back together in no time. The next attempt to start went well until the huffer cart flamed out. Once again luck was on our side as the engine was into the start far enough that it didn't matter at this point.
Preliminary checks were done such as oil pressure and idle engine parameters. Ben taxied the Scooter to the tie downs and we tied the tail down for the runs.
Josh did the minor adjustments we needed. Here he is making an adjustment to the tailpipe clamp to cool the engine down a little.
The last part of the run entailed several throttle advances to full power to verify power settings. This is probably when we shook Zack a bit at the museum. After these accelerations the guys were finished and proceded to idle for cool down time before shutting it down.
When all was said and done, we have a very good engine. A few small items need our attention such as a small fuel leak at the fuel pump and a couple of minor hydraulic leaks. We'll be headed up North this Monday to fix the hydraulic leaks and work on rigging the canopy. The fuel leak will require some parts from the engine shop in california. Our plan is to try to bring the Scooter home around Nov 20-22 time frame. I'll try to update before then so any local Wixers can stop by and hopefully see some air under her wings.
