Apologies if it did appear and I missed it.

A few weeks ago we had a long conversation about issues surrounding the LNC2 gear hydraulic issues. Some folks presented some creative solutions.

However, I have a suggestion to add to those people because the "solutions" offered did not address the root cause and are therefore "masking the symptoms."

There are many people who never experience these problems, leading me to believe that the right pump configured the right way does not experience it. Period.

That doesn't mean that the solutions aren't a good backup.

So, here is my suggestion: Return your pump to Parker/Oildyne. When I was troubleshooting my pump problem, they offered to refurbish the pump for a very reasonable charge ($100-200, I forget). I did not do that because by then we had determined that I did not have the recommended pump.

If you do this, and make it very clear that it is for a Lancair, they have a couple of guys who know exactly how it is supposed to be configured, and can probably correct any issue.

Blue skies all.
