Combi Conversion
A Combi Conversion can be made from the removal of cabin seats from a Corporate
Commuter and the removal of cabin seats and furnishings from an Executive Interior aircraft.
The Combi Interior consists of 2 crew seats and payload or a combination of seats and
payload. Cargo nets can be installed to attachment points at frames 24 and 27. Refer to
Section 2, Limitations,
The airplane is weighed at the factory before the time of delivery. When other interior
configurations are required, adjust the Basic Empty Weight and Moment and complete the
landing form as follows:
−
Make a temporary mark on the seat rail at the forward edge of the Corporate Commuter
Seat(s) or mark position of the Executive Seat attachment fittings of the seat(s) to be
removed with masking tape or similar material to expedite reinstallation. Remove the
passenger seats and furnishings as required
−
Use the passenger seats and furnishings weight and moment data in the relevant Interior
Code section and determine the total weight and moment difference of the interior items
removed from the aircraft.

Note
The figures are taken from the “Passenger Seats and Furnishings Weight and Moment
Chart”.
Enter the Total Value on line 2 of the Loading Form,
.
Calculate the cargo moment as follows:
1
Locate one of the luggage net floor attachment points at frame 34.
2
Measure distance from the attachment point to the center of the cargo i.e. 35 in (0,889
m).
3
The fuselage station dimension at the luggage net attachment point is 361.15 in (9,170
m)
4
The arm of the cargo is the fuselage station dimension of the net attachment point minus
the distance to the center of the cargo.
5
Example:
−
Distance to cargo center = 35 in (0,889 m)
−
Net Fuselage Station = 361.15 in (9,170 m)
−
Cargo Arm = 361.15 in - 35 in = 326.15 in (9,170 m - 0,889 m = 8,281 m).
6
Enter the cargo arm and the weight of the cargo plus tie down straps and cargo arm on
the Loading Form.
