Gear allways retracts correctly and without problems. On occasions when
extending the landing gear it does not come down at all, all you can hear
is
a loud squeal as the hydraulic pump appears to pumping against a brick
wall
(similar noise to when holding a car's power steering against the stops)
It
allways extends with the emergency extention without problems.

Whether it's computers, boats, cars, plumbing, etc, it seems when sh%*
happens to me, mystery problems invariably have 2 (unrelated) things going
on - at the same time. Trips me up every time - until I figure it out ....or
stumble upon the (hidden) second problem.

Good luck solving your mystery.

Ass-u-me nothing!!!
