      When they switched from 3 blades to 4 blades did they put in LSGI? Bob

    • The Flasher
      By Sonny · Posted
      Flasher There were three little old ladies sitting on a park bench having a quiet conversation when a flasher approached from across the park. The flasher came up to the ladies, stood right in front of them and opened his trench coat. The first lady immediately had a stroke. Then the second lady also had a stroke. But the third lady, being older and more feeble, couldn't reach that far.
    • #4 prop fails droop check

      NATOPS is right on the money. The wiring going to the speed bias servo motor or reference winding could cause this snag. Just to help narrow your wiring search, I would not bother with your pulse generator circuit. If there were a malfunction with the #4 pulse generator electrical circuit, the syncrophaser would see zero RPM and increase 2% to compensate, bringing your #4 RPM up to 102%. I've seen that happen several times. The 61 FI has a great wiring schematic for this system, as well as all the required resistance readings. Start your troubleshooting by ohming out the sync rack. This takes at least two people, one in the hole and one on throttles/switches. Check all circuits to ground in case there is a short to ground. When the wiring in the conduit is shorted to ground, your sync rack multimeter checks will all pass, but one of the circuits will inadvertently show continuity to ground. When ohming out potentiometers, always use an analog multimeter! This allows you to detect very minute dead spots. You might check the condition of the electrical conduit going through the Reduction Gearbox QEC baffle. Sometimes, the fairlead phenolic blocks are installed incorrectly, causing choking or pinching damage to the conduit. Additionally, the synchrophaser wiring is located in a bad position, often damaged by equipment behind FS245 where the wiring goes into the synchrophaser. If your aircraft synchrophasing system has been rewired to the new sleeved wiring bundles, this is less likely, but still something to look at. You must be meticulous when checking the 16-pin Valve Housing conduit. If you disconnect it from the valvehousing, you may shift the wiring within the conduit to fix itself as you shift it around. When checking that conduit, continuously move the conduit in front of the baffle around while reading the multimeter to make sure you are not making the problem go away from moving the internal wiring away from the short. Finally, if your aircraft recently underwent major maintenance in the wing, there is a chance the wiring fault is in the leading edge in the right wing somewhere, and the FCF crew missed it. We got an aircraft back from depot with crossed wires before, so I know it's possible.

      Wiring... The VH only does what its told (increase/ decrease blade angle), the Sync tells it (VH) what to do (increase/decrease blade angle) based on the blade position reported by the Pulse generator and the position needed (calculated by the sync box) to achieve syncrophasing. If the blade position or the increase/decrease blade angle "command" are not know then sync droop is not possible.   I would break out the wiring diagram and start checking wires... starting at the speed bias motor.

      We have an aircraft that has continually failed a #4 droop check for the last 2 months.  We have changed the V/H 4 times, Syncrophaser twice, pulse gen, pulse gen magnet, tach. gen, and then the entire prop with no luck.  We were discussing with the engineers and they had us change the #1 V/H to see if tha had any affect, it did not.  Anyone have any ideas?
    • Old Cowboy
      By Sonny · Posted
      An old cowboy sat down at the Starbucks and ordered a cup of coffee. As he sat sipping his coffee, a young woman sat down next to him. She turned to the cowboy and asked, 'Are you a real cowboy?' He replied, 'Well, I've spent my whole life breaking colts, working cows, going to rodeos, fixing fences, pulling calves, bailing hay, doctoring calves, cleaning my barn, fixing flats, working on tractors, and feeding my dogs, so I guess I am a cowboy..' She said, 'I'm a lesbian. I spend my whole day thinking about naked women. As soon as I get up in the morning, I think about naked women. When I shower, I think about naked women. When I watch TV, I think about naked women. It seems everything makes me think of naked women.' The two sat sipping in silence. A little while later, a man sat down on the other side of the old cowboy and asked, 'Are you a real cowboy?' He replied, 'I always thought I was, but I just found out I'm a lesbian.'
