Subject: Hot TITs on X country leg. LIVP
We returned home yesterday from East Coast visits following LOBO mtg in Greenville, SC.
On the way to Greenville after an intermediate stop in NE, we experienced an engine problem that I brought to the attention of anyone at LOBO who would listen and give advice including Neil George from TCM with Allen Barrett hooked into the discussion by text and cell phone.
The short story is that when I reached my planned VFR altitude of 15,500 and levelled off I pulled back power but forgot to lean or reset prop for about ten minutes. Then when I remembered and tried to lean the engine, TITs skyrocketed followed by hot EGT readings. See the attached link to the Savvyanalysis graphing of the engine behavior and see if you can come up with what went wrong. When you review the graph, you’ll likely notice that I tried twice more after the initial leaning to see if I could get lean of peak and the engine emphatically let me know it did NOT like what I was doing.
I can tell you the problem has been resolved and we flew the airplane around the country for another week with no repeats. Now I'm interested to know what LMLers might think caused this because I was totally surprised when I learned what the real problem was.
Some of you who were supportive at LOBO already know the answer so let’s see what others come up with. I have many people to thank for amazing help in finding and correcting the problem so I want to go on record as one of the most appreciative people there could be for LOBO, our many vendors and for pilots around the airport in Greenville who gave advice, time, materials, loaned tools and so on.
