Section VI CARGO LOADING
6.14 CABIN DIMENSIONS.
Refer to Figure 6-7 for dimensions. For loading, and weight and balance purposes, the helicopter fuselage is di-vided into .ve compartments, labeled A through E, three of which are in the cabin, C, D, and E (Figure 6-7). Tiedown .ttings are rated at 5,000 pounds each. Cargo carrier re-straint rings are at stations 308 and 379, to cover the 71 inches of longitudinal space.
6.15 CABIN DOORS.
Cabin doors are at the rear of the cabin on each side of the fuselage. The door openings are 54.5 inches high and 69 inches wide; maximum package sizes accommodated by the openings are 54 inches high by 68 inches wide.
6.16 MAXIMUM CARGO SIZE DIAGRAM FOR LOADING THROUGH CABIN DOORS.
Figure 6-7 shows the largest size of cargo of various shapes that can be loaded into the cabin through the cabin doors.
6.17 TIEDOWN FITTINGS AND RESTRAINT RINGS.
The tiedown .ttings (Figure 6-7) installed on the cargo .oor can restrain a 5,000-pound load in any direction. All tiedown .ttings incorporate studs that are used to install the troop seats. Eight net restraint rings in the cargo compart-ment prevent cargo from hitting the bulkhead at station 398, or entering the crew area. Each restraint ring is rated at 3500-pound capacity in any direction.
6.18 EQUIPMENT LOADING AND UNLOADING.
6.18.1 Data Prior to Loading. The following data should be assembled or gathered by the loading crew be-fore loading (Refer to FM 55-450-2, Army Helicopter In-ternal Load Operations):
a.
Weight of the individual items of cargo.

b.
Overall dimensions of each item of cargo (in inches).

c.
The helicopter’s center of gravity.

d.
Floor loads for each item of cargo.

e.
Any shoring that may be required.

f.
When required, the location of the center of gravity of an individual item of cargo.

6.18.2 Cargo Center of Gravity Planning. The detail planning procedure consists of four steps, as follows:
a.
Determine ALLOWABLE LOAD from LIMITA-TIONS section of DD Form 365-4.

b.
Plan the location in the helicopter for the individual items of cargo. Since the CG of the load is determined by the station method, then speci.c locations must be assigned to each item of cargo.

c.
Determine the CG of the cargo load as planned. Re-gardless of the quantity, type, or size of cargo, use the station method.
