Certified Aircraft: USAF C-130, C-17, and C-5

Conditions of Certification:

1. Maximum Weight for Air Transport:

File Number 2016.04.19 Rev 6

a. MJ-1B/C

Gross Vehicle Weight: 5,700 lbs (does not include pallets, approach shoring or restraints)

Axle Limits:

Front Axle: 1,200 lbs

Rear Axle: 4,500 lbs

b. MHU-83

Gross Vehicle Weight: 8,620 lbs (does not include pallets, shoring or restraints)

Axle Limits:

Front Axle – 2,600 lbs

Rear Axle – 6,000 lbs

2. Item Preparation:

a. Tire pressure shall not exceed 100 psi.

b. Palletized Option: The MJ-1B/C can be on a single pallet or centered on a pallet train, without shoring. The MHU-83 shall be put on a two pallet (T2) train with shoring under the frame as specified in paragraph 5. Restrain the item to the pallet/pallets per paragraph 4.

c. Shipper is responsible for providing all shoring materials. See paragraph 5 for specifications.

d. All hazardous materials (to include fuel level, batteries, etc.) must be prepared and certified for airlift in accordance with TM 38-250/AFMAN 24-204(I). Do not consider this air transport certification as approval for hazardous materials. Authorization for airlifting hazardous material is the responsibility of AFMC/A4RT (DSN 787-4503 or COM (937) 257-4503).

3. Loading Instructions:

a. The bomb lift can be loaded using general loading procedures as listed in the respective aircraft cargo loading manual.

b. Approach shoring is required for rolling stock configuration. See paragraph 5 for specifications.

4. Restraint Requirements: The bomb lift and all accompanying cargo must be restrained to meet air transport requirements of 3G forward, 1.5G aft and lateral, and 2G up. In addition, stored or installed equipment must meet these requirements and be capable of withstanding a 4.5G down load.

Tiedown rings can be used for 10,000 lbs of restraint each. Use frame points for additional restraint.

CAUTION: Care should be taken to avoid damage to the oil filter or any delicate parts when applying restraint (Figure 3).

Figure 3. Damaging Oil Filter

5. Shoring Dimensions & Diagrams:

a. Approach shoring: Recommended dimensions for 9° approach angle using the same approach shoring across all three aircraft and for both bomb lifts. Requirements for other configurations are in the applicable aircraft loading manual. User may use prefabricated ramps.

NOTE: The use of certified prefabricated aluminum ramps while loading these items will eliminate the need for any wood shoring; including the pedestal shoring.

NOTE: The shoring dimensions listed below were created so that there is a standard length of approach shoring for all three types of aircraft. Previous shoring configurations for each bomb lift and for specific aircraft can also be used; since they were already created by some units; please see paragraph 5b for these options.

C-5 Forward Shoring (Forward Kneel) Pedestal Shoring “A” 16” L x 13” W x 4” H (2 each inboard)
