Laurie, First of all, a very nice job of taking care of this emergency! Also, thanks so
much for the report to the rest of us. As you note, these things always provide useful information, and this one caused me to think again
about my own airplane. Most of my IV-P electrical system is protected with fuses; the alternators and hydraulic pump being the
exceptions, and with the CB's for these made very readily accessible for just the situation you encountered. My concern is that you
didn't have sufficient hydraulic fluid to lower/lock the gear with the manual pump. I determined during construction that the pickup
tube for the manual pump extended lower in the tank than the electric pump pickup, and just let it go at that. I did not test this at all.
If you have any thoughts about why you didn't have enough fluid left to use the backup system, I'd be
most appreciative. Could the pitch attitude of the aircraft had an effect? Other thoughts? Based on your experience, I'm thinking of
draining down my system through the electric pump and then trying the manual pump. Like I said, I took this one on faith of
the designer and did not test it, although it would have been easy to do during build. Again,
nice job landing the aircraft, and I'm happy you sustained minimal damage in the process. Thanks especially for your comprehensive report.
If you find more, especially about why the emergency pump didn't work, we'd all appreciate
hearing. Bob Pastusek For LOBO
