Lancair 320 Builder’s Manual Page 378, Section 14-8 FREE-FALL TEST v.84. “The main gear will usually fall about half way very quickly and the remaining half could be a slow struggle for the springs. This is o.k. In fact, it is o.k. if they never do lock down by themselves but you must measure the pressure against the sides of the tires that is required to bring them down and locked.”
v.85. “If the main gear does not lock down, take a scale and press against the inside of the tire bottoms. The force required to lock the gear down should not exceed about 5- 8 lbs. This force is easily achieved by simply kicking a little rudder left to create a side slip which will lock the left main, then right rudder to lock the right main. If more force is
required, then you have a “bind” condition somewhere in the linkage or the springs are stretched out of shape. You’ll have to correct the condition before flight.” Thanks to Steve Rosenzweig for pointing this out and saving me a ton of worry. I did the test and it takes less than 2 lbs to bring my gear down and lock it. Sometimes it will come down all by itself if you wait a minute. I just wanted something to show my DAR in case this happens, now I can show him my manual. Thanks to everyone for the input and there are no leaks on the up or down side of my gear. Pump does not turn on for 1 hour either way - did not test it past an hour but I after 4 days, I turn on the master and the gear pump does NOT turn on meaning my gear is still down, locked, and LEAK FREE - --- YIPPEEE Matt
