- Fluorescent penetrant inspection is a critical characteristic. Fluorescent penetrant inspection shall be performed IAW ASTM E1417 for cracks. None allowed.

- Magnetic particle inspection is a critical characteristic. Magnetic particle inspection shall be performed IAW ASTM E1444 for cracks. None allowed.

- Eddy current inspection is a critical characteristic. Eddy current inspection shall be performed IAW DMWR criteria for cracks.

None allowed.

- Component plating amd subsequent bake is a critical characteristic and is required per the overhaul process. Contractor shall acquire proper plating facilities and/or equipment to perform the outlined procedures.

- Shot peening coverage is a critical characteristic. An AMCOM/CCDEVCOM approved source shall be utilized when shot peening is a critical process. Approved sources shall be obtained from AMCOM.

YCritical Safety Item?

Per coordination with Cargo Division, the following are the current airworthiness issues, new ECPs affecting CSI, concerns over reliability, durability issues that would affect the overhaul of the subject item in its current configuration:

1) Forward and Aft Swashplate Rotating Rings (114R3464-9) have been discovered with cracks. As a result, recurring Eddy Current inspections were implemented on aircraft and at overhaul. Airworthiness Impact Statement, AWIS 19-004, 9 April 2019, was issued as an update to AWIS 06-017, Revision 2, dated 23 April 2013. The new risk analysis included a revised crack growth analysis using representative load spectrums for the CH-47 and MH-47. It also takes into account the impact that process improvements, including the bearing retention flange flatness requirement, have had on reducing Eddy Current rejections at the depot.

2) CH-47 aircraft have experienced Swashplate Bearing, PN 114RS308-1/-2, failures which resulted in severe damage to the aircraft. The Swashplate Bearing lower cage "popped" from the bearing becoming entangled with the Swashplate Rotating Ring Lower Seal (PN 114RS306-6) retention (garter) spring. The spring was then ingested into the bearing, jamming the Swashplate Rotating Ring. Visual inspection requirements were implemented for the field and in August 2017, Aviation Safety Action Message, H-47-17-ASAM-07-Update 1, was issued to direct a mandatory inspection for and removal of the garter spring from the Lower Swashplate Seal of all Forward and Aft Swashplate Assemblies by 22 August 2018.

3) The Forward an Aft Controllable Swashplates are undergoing a redesign effort as part of the Improved Rotor System program which is part of the CH-47 Block II Aircraft Component Improvement Program (Block II ACIP).

Special Airworthiness Considerations

FCDD-AMA-M-Sustainment has verified the CSI/NST status through the ARISE CIM on 27 June 2019 and the NHA is CSI and Non-NST. The subcomponents are CSI and NST. Engineering testing like Fatigue, Endurance, and Interchange are not required for overhaul. Updated NHA table in ARISE database. No other changes. DEM

Other Requirements / Comments

If the item is not a CSI and no adequate DMWR is available, approved sources, if any, are listed by CAGE as follows:

Additional CSI Requirements

CSI Contains CSI Replacement Parts? YEngineering Testing Required?

The Contractor shall flow down the Critical Characteristics and QE-STD-1 to all Suppliers of CSIs.

The solicitation/RFP shall require that all proposals/responses include a special tooling and test equipment section that addresses the contractor's plan to meet all government special tooling and test equipment requirements with either:

1. Physical possession of the required tools, 2. Confirmed requisitions for the required tools, 3. Confirmed arrangements for subcontracting the processes requiring the special tools, or 4. Specific plans describing their technical approach to develop equivalent tools.

Critical Tools and Test and Inspection Equipment Requiring AED Approval for Substitutes

MEOs Required for Competitive Contract?

Special Post-Contract Award Requirements

The Prime or OEM is required to submit a Frozen Plan 30 days after contract award to Engineering Directorate (ED) and Aviation Engineering Directorate (AED). The Frozen Plan will be reviewed and require approval by ED and AED prior to government acceptance of contract deliverable assets.

Other Requirements / Comments (Part II)

The applicable DMWR contains detailed procedures regarding IUID requirements for this component. These procedures can be found in MEOs D1907, D1908, and D1909.

Other Requirements / Comments (Part III)

FCDD-AMA-M-Sustainment has re-verified the CSI/NST status through the ARISE CIM on 31 July 2019 and the NHA is CSI and Non-NST. The subcomponents are CSI and NST. Engineering testing like Fatigue, Endurance, and Interchange are not required for overhaul. No changes made. DEM
