I had a near one of these after my 2.5 hour engine  break-in flight, a hydraulic line failed in flight and when selected the gear  went 1/4 of the way down and stayed there.  I felt a bit of excitement  because during the annual it was noticed that the emergency gear pressure gauge  had been frozen in position, the gauge was removed diddled with and returned to  service.  Because the gear stopped at 1/4 travel my immediate thought was  that the gauge was still inop and that I may not have any nitrogen pressure to  push them down.  I was still moving along fairly fast (160 MPH) so I slowed  it down to about 110 MPH which finally lit up three beautiful green  lights.

Indeed a testimony to a well thought out design.   

I had the same experience when I lost total hydraulics once. Lowering the speed makes the gear pop smartly into place. Thanks, Ted!

Actually it is Tom, (I do have a cousin named  Ted).

  

 I would like to see a method to test the movement of the  gauge during the walk around to insure it is not "stuck" in place.

I think he was thanking Ted Smith, the brilliant  designer of our airplanes .

Same when one of our clevises (clevi?) broke and  disconnected a retract cylinder.. Gear descended and locked only after speed was  reduced.

  

 Found more cracked clevi during gear rebuild this  year. Also, some retention pins had cocked in the gear and scored the hell out  of the inner wall of strut cylinders. They are available, but you can buy an  airplane for the price of them. (There is a shop rebuilding them.)

  

  Found the tiniest of leaks in the nitrogen system  lines that would take a couple weeks to leak down, but was a pain in the ass.  The guys used freon and a sniffer. Man is that thing  sensitive.



  

 Our nitrogen pressure gauge stuck before and after  a rebuild of the gauge. Standard preflight includes a sharp tap on the thing to  get it to return to where it belongs. I suppose I'd miss having to tap it if it  ever works right again.

Had a hydrolic line shear off in the wheel well just after take-off in a 500B.  Emergency checklist slow her down and whala...another thanks to Ted on a superb design.

I think the gauge should have a dump valve immediately  before the gauge just to dump what is in the gauge, in that way the needle  would drop to zero and then back up to current pressure.  The amount of  loss might mean a quick top up every couple of months.
