Started today with getting the air hose connections ready for the oil purge. I then continued work on PAP G4 checking prop pitch. My angles were a little off. One showed about 71.2 and the other about 71.8. So each were adjusted to the recommended 71.4 +/- 0.1.
I then tested the static and pitot tubes as per PAP G5. A tube and syringe were placed over one static port with modeling clay while the other was covered with tape. Suction was applied and timing was recorded to see how fast the altitude on the EFIS dropped. The max allowed was 100 ft in one minute. Mine recorded between 300-460 seconds for each 100 ft drop. Static PASSED.
The pitot tube was then tested. Again I attached a syringe and tube to the pitot tube and applied pressure and measure time of airspeed drop on EFIS. At first the airspeed dropped quite rapidly so there had to be a leak somewhere. I check the safety wire connection at the aft of pitot tube. I also decided to place safety wire on the pitot tube connections in panel. I then retested. In doing so I also pushed the tubing on the syringe more (which may have been the only issue in the first place). Pressure was applied and timing recorded. The max allowed is 10 kt per minute. My times were between 380-400 seconds per 10 kt drop. Pitot PASSED.
I also got a call that my data plate was ready to be picked up from the engravers. As per the DAR the only required entries are the Manufacturer, Model, and Serial number so that was lines I had engraved. I returned to the hangar and installed it on the plane as per plans.
I need to have a few other people available to do the oil purge, so as soon as I can get that done I will be able to start the engine and go through the other tests.
Time: 3.5 hrs
