Physical retrieval of the delivered vehicle back to the manufacturing plant; or Contracting and overseeing an authorized local repair facility to perform required retrofits.

Modification Completion & Notice: OEM advises the Sponsor in writing once modifications are complete.

Resubmission: Sponsor inspects physical modifications, updates the TDP, and submits the package to ATTLA for formal evaluation and certification memo issuance.

B. Special Assessment: Physical Test Loading and SDDCTEA Pull Testing

1. Physical Flight Test Loading (Uncertain Transportability) Applied when computational engineering analysis cannot conclusively establish loading clearances or structural margins.

Test loadings are scheduled as Special Airlift or Transport Missions (SAAM) requiring a formal test report.

Funding & Coordination: The purchasing customer / Government Agency Sponsor is responsible for formally requesting the test load mission and covering all associated airlift and personnel costs.

2. SDDCTEA Structural Analysis & Testing (MIL-STD-209K) Lead Time: OEM must supply provision dimensional data, material specifications, and structural finite element results to SDDCTEA at least 90 days prior to scheduled physical provision testing.

Objective: Upfront analytical modeling reduces destructive testing risks and may eliminate the requirement for physical pull testing if margins are sufficient.

Agency Coordination:

6. Vehicle Configuration Reduction Criteria (1 Man-Hour Rule) If an equipment item must be reduced in size or height to fit cargo door envelopes:

Tool & Time Thresholds:

Mechanically attached (non-welded, non-riveted) components may be removed or relocated using standard hand tools.

Total removal, relocation, and tiedown time must not exceed 1 man-hour.

Reassembly time back to fully operational configuration must not exceed 1 man-hour.

Operational Constraints:

Self-Mobility: Vehicle self-mobility must remain intact in its reduced configuration (must be capable of driving on and off aircraft).

Stowage: Dedicated onboard tiedowns and stowage brackets for removed components must be integrated on the vehicle.

Shoring: The vehicle must load without auxiliary wood shoring unless structurally unavoidable.

Delivery State: The vehicle must never be delivered to the Government end-user in its reduced configuration.
