A few ergonomic issues

@aviatoreb what shop did your seats?

 

SCS interiors in Duluth, MN.  Their workmanship is second to none, but their prices are better than most.

1) I always knew the fit would be tight.. that is just one of the trade offs for great Mooney efficiency, but I feel like my spine is literally twisted into a sideways “s”..definitely not sustainable.  Can’t quite put my finger on it…almost like the right side of the left seat is a little lower (it isn’t), and then I’m sort of twisted to the left so I can maintain a vertical posture.   I am not even sure I’m characterizing the situation correctly…still trying to feel it out.   All I know is that the way this feels is more like torture than fun, and enough of it will land me in physical therapy.  I’m not small but not really a big guy either…about 5’11” and 195 so there has to be a solve.

 

If you feel the whole seat is leaning, you may want to check the bellcrank on the bottom for a crack. My partners and I experienced the same symptom a few months and when looking at the bottom of the seat noticed this crack, which is fairly common. The fix involved a weld and extra reinforcing straps.

I just went to the airfield and sat on the passenger side (where there are no rudder extensions).  Voila!   Problem solved!    If I move up, the elbow rest is not nudging me out of my seat, the yoke is a reasonable distance from my stomach, and while I'm a bit close to the dash, not a big deal.   This has just changed the problem from a 15 AMU interior panel retrofit to couple of hours (maybe) removing rudder the extensions.  This forum is amazing.  Thanks again.

The extensions are easy to remove, but you have to work in a tight space. Roll the trim all the way forward to get the yoke out of the way and take the seats out and it will be easier. If you don’t already have them, you should get a Service and Maintenance Manual and an Illustrated Parts Catalog. 

Here are a couple of drawings that show how the 3” extensions are installed on the pedals and how the pedals are mounted with no extensions.

The 3” extensions change the geometry of the pedals. After removing them, you may find that the angle of the pedals when applying the brakes is too far forward. This requires adjusting the rod length for the master cylinders from underneath the left exhaust cavity.

[mention=11849]ArtVandelay[/mention] [mention=17346]PT20J[/mention], the plane is 1979 and the seats recently reupholstered and look nice but with minimal real support.  One thing your plane and mine have in common [mention=11849]ArtVandelay[/mention] is the arm rest that protrudes from the wall.  It occupies an inch of precious thigh space  and it's one of the reasons I'm sitting a bit right of center  I wonder if there is a way to borrow space from the wall and RECESS the armrest. Anyone know if that's possible or who does that sort of work? 

The armrest in my '64 C is recessed in the side panel. The plastic inside the panel is molded so that the armrest is basically an indentation with a flat bottom, like the soap shelf in a prefabbed shower stall.
