Here's the situation. I teach in a BE95 and for the last several months the unfeathering accumulators have been very intermitent and recently, they have not worked at all. MX has spent all kinds of time on them, even a guy from the big prop shop was there today. When I arrived to fly, we went up, shut down the left and the prop would not budge when we tried to unfeather.
Using the starter was of no use, it just wouldn't turn over. As soon as we landed, it started (in feather) just fine. WHen I feather it on the ground and then shut down and then move the prop lever forward, it comes out of feather but gradually (over 30-45 seconds) goes back into feather. Also noticed oil on the engine nacelle in the area of the accumulator bottle after shut down today.
Why does it unfeather on the ground but not in the air?
Any suggestions on how to consistently start it in the air in feather? I have been successful in the past, but not recently (burned up a starter 2-weeks ago.)
Getting tired of single engine landings (3 in last month).
Thanks,
