I inherited a gear problem on a retractable gear RV-4 after my mechanic friend left to ferry a Baron to Brazil just after Christmas, and I and several A&P's have torn out too much hair trying to get the gear to come up and go back down without intermittent failures to retract.
I emailed John (Waiter) last night and asked him to call me, as I had found more information on his website than anywhere else I could look, but could still not solve this problem. He called me this morning and helped immensely with trouble-shooting what could be wrong and advised me to remove the hydraulic pump/motor assembly from the aircraft and how to test it by itself to eliminate it as the culprit.
I even pestered John at work later this afternoon, and he kindly offered more assistance.
Late in the afternoon, after following John's advice, I was able to locate what I "think" will be the cause of all the problems.
So, here's thanks to "Waiter" for his help today, and for all the effort that he has put into his website that has probably helped many others who may not have had to call the real expert to help solve their super vexations.
Many thanks, John and best regards always,
Barney
