Why the Skyvan??? Anyway . . .
This info comes from the flight manual for the SC-7 Skyvan Series 3A Variant 100 and from the conversion training notes.

*Structural info:
- Fuselage construction (ribs, skin .etc)
The fuselage is essentially a box-like structure with conventional frames supporting double skin panels in which a smooth outer skin is bonded to a corrugated inner sheet. The nose portion (built using a more conventional skin and stringer construction) contains the flight compartment and the nose undercarriage and mounting.The underside of the fuselage aft of the main section is upswept to the tailplane. This upswept surface consists almost entirely of a large door which is hinged at the rear end and opens upwards into the fuselage allowing direct loading from the rear of the aircraft. It is possible to open and close the door during flight.
Length: 12.22m Height: 4.59m
-Wing structure (No. of spars.etc)
The wing comprises a spar-box structure, a leading edge and trailing edge, a wing tip and slotted type flaps and ailerons. The wing is braced by an external bracing strut which is not structurally part of the wing. The main spars, extending from root to tip and a leading edge spar, extending from outboard of the powerplant mounting and covered top and bottom by a double skin, constitute the spar-box structure. The skins are structurally continuous along the complete length, and consist of a corrugated inner skin bonded to an outer skin which reduces in gauge toward the tip. The corrugations are semi-circular in shape and run parallel to the spars.

*Some sort of cutaway or structural diagram - tricky
*Engine shaft horsepower
The powerplants are Garrett AiResearch TPE-331-2-201A turboprops rated at 715 shaft horsepower and 755 ESHP (includes contribution from jet thrust). Propellers are Hartzell HC-B3TN-5C or –5E three blade or Hartzell HC-BT4N-5C (4 blade) metal props using single action hydraulic control and rotating clockwise viewed from the rear.
*Undercarriage construction
The aircraft is fitted with a non-retractable tricycle undercarriage. The nosewheel is steerable and of standard oleo-pneumatic design. The mainwheels are of the training link type and can be braked differentially for steering. Typical tyre pressure is 42 psi all round.
