PA38 Climb Performance
We operate two Mark 2 PA38s.
One of them seems to have a significantly poorer climb performance that the other one. We had thought that the installation of a new engine would improve the climb performance but it has not done so. Static RPM is the same on both a/c. We have both a/c reweighed and there is only a trivial difference in empty weights (in fact the a/c with poorer climb is about 12 lbs lighter).
The propellor pitch on both a/c is exactly the same.
We have asked engineers to check the rigging but nothing seems to be untoward.
I just wondered if anyone had any bright ideas as to why the climb performance was significantly different.
