Is it just me, or does the way the manual says to mount the new style landing

gear hydraulic pump pretty much guarantee a system that will be next to

impossible to maintain?  The way I see it, mounting the pump assembly behind

the aft baggage bulkhead on the passenger side would put the reservoir up

against the fuselage wall, underneath the shoulder harness mounting point,

making it all but impossible to get to.  Where's the best place to mount these

new-style hydraulic pumps?  On the pilot's side (any interference with

controls)?  On the front of the aft baggage bulkhead?  Any other ideas?



Thanks,



Gary

I'm not sure there is any "best" place to mount the hydraulic pump, but

you're right - behind the baggage bulkhead is not that great of a place for

it. I have lots of fiberglass burns and bruises on my forearms to prove it!



In the "olden days", the pump was placed there for CG considerations. But

if like me,  you are heavier that 170 lbs., you will have to move some

weight forward anyway, so why not the hydraulic pump?



My friend mounted his on the *front* side of the baggage bulkhead, then

built a nice little removable cover over the whole thing. It subtracts a

little room from the baggage area, but what the heck, you can only carry 50

lbs. there anyway. It has not been a problem for him.



I say just put the darn thing where you can get at it!
