B: Identifying T-34 Wings on Models 35 and 33

[Curtis Boulware]

Steve,

Some of the differences include heavier skin thicknesses.  The leading edges 
are .040 thick instead of .032.  Because of this, T-34 leading edges fair 
better in hail than Bonanzas.  Both leading edges also have wing walk all 
the way to the leading edge nose spar and a fresh air inlet screen at the 
leading edge root.  There is also a large diagonal rib just outboard of the 
25 gal fuel cell bay.

The box section skins are also a little heavier in places.  Most of the 
skins are .025 or .032 instead of .020 and .025.  Wing walk corrugation is 
on both sides.  The flap actuator bay areas around the rear attach fitting 
are also completely closed out with a span-wise rib.  The rear spar is 
nearly identical.  I have used new Bonanza spar caps and spar cap support 
angles to repair 34 wings.  Almost all of the box section and leading edge 
ribs are identical in station number placement and thickness.  I haven't 
found one yet that isn't a 35 prefix part number.  Access panel holes are 
completely different.  T-34 has Airloc stud fasteners into a back-plate with 
receptacles.  Bonanzas use sheet metal or machine screws into standard 
nutplates.  T-34's also have one more inspection panel just outboard of the 
outer gear door.
