The UK CAA through CAP 3037 has taken the EASA baseline from 1321/2014 and extended it significantly in operational depth.
This includes:
• Physical configuration and environmental controls of storage areas.
• Enhanced inspection rigor, with checklists and documented decision logic.
• Personnel qualification and training standards linked directly to roles.
• SUP procedures and DG compliance embedded within stores functions.
• Mandatory documentation standards across all component categories.
These changes reflect a shift toward a risk-based, safety-centric logistics framework anchored not just in compliance but in robust internal control.
CAP 3037:
• Requires a clearly defined and physically secure receiving inspection system:
>> Secure access for authorised staff only.
>> Physical segregation of goods-in, serviceable stock, and unserviceable/quarantine zones.
>> Specific guidance that cages, demarcated zones, and controlled access points be employed.
• Inspection scope includes:
>> Conformity checks against order.
>> Visual inspection of packaging, part condition, and identification marks.
>> Verification of documentation authenticity and traceability.
• MOE Section 2.2.3 must detail the full procedure.
• Receiving areas are part of regulatory compliance—not just operational preference.
CAP 3037 enforces the physical, procedural, and staffing dimensions of receiving inspection in ways that go well beyond EASA 1321/2014’s more generic guidance.
CAP 3037:
• Places strong emphasis on documented supplier evaluation, mandating:
>> An evaluation process described in MOE Section 2.1.2.
>> Evidence that Part-145 holders have independently verified the reliability of suppliers.
>> Continuous re-evaluation and periodic performance review.
>> Explicitly states that holding certifications (EN/AS9120, ASA-100, FAA AC 00-56) does not exempt suppliers from scrutiny.
CAP 3037 turns optional supplier oversight into a mandatory quality control process, increasing accountability for every component entering the store system.
CAP 3037:
• Defines a mandatory training syllabus for logistics personnel including:
>> Part identification and conformity assessment.
>> Handling of serviceable, unserviceable, and suspect parts.
>> Storage, segregation, and documentation.
>> Regulatory awareness and functional testing where applicable.
• Recurrent training must be formalized (AMC3 145.A.30(e)) and stored in records.
• Allows technical support from CAMO staff for complex components (e.g. engines, APUs).
• Training procedures must be documented in MOE Section 3.9.
CAP 3037 establishes comprehensive competency standards and documented training records, whereas EASA maintains a more discretionary approach.
• Documentation Requirements (UK CAA Form 1, CoC, Other Certificates)
CAP 3037:
• Introduces a dedicated SUP protocol, requiring:
>> Immediate isolation of suspect parts.
>> Dedicated quarantine procedures.
>> Reporting mechanisms with traceability.
>> SUP awareness training for logistics personnel.
• Clearly links receiving inspection activities to proactive SUP prevention.
CAP 3037 elevates SUP prevention from a passive reporting function to a proactive logistics control embedded in stores workflows and staff competence.
CAP 3037:
• Requires a specific written procedure for receiving inspection:
>> Must be defined in MOE Section 2.2.3.
>> Linked with post holder responsibilities under Section 1.3.
• Includes an example Receiving Inspection Checklist (Appendix A) with step-by-step checks.
CAP 3037 requires structured and traceable written documentation linked to MOE chapters, improving regulatory visibility.
Dangerous Goods (DG) / Hazardous Materials Awareness
CAP 3037:
• Introduces a Dangerous Goods Program (DG) specifically for stores staff.
>> Includes training, identification, and segregation of DG items.
>> Directs alignment with UK DG standards (equivalent to HAZMAT in FAA context).
Key Difference: The UK CAA explicitly embeds DG awareness into stores procedures, highlighting safety compliance for items received into inventory.
CAP 3037:
• Provides detailed sections for:
>> New vs. Used vs. PMA vs. Standard parts.
>> Special exemptions for ELA 1 and ELA 2.
>> Acceptance of parts without release documents, under exceptional conditions (e.g., AOG).
CAP 3037 provides operational guidance across part categories, helping stores teams make safe, compliant decisions beyond the scope of the regulation text.
CAP 3037:
• Strictly enforces MOE integration by section:
>> 2.1.2 — Supplier Evaluation.
>> 2.2.3 — Receiving Inspection Procedure.
>> 3.9 — Training Records.
>> 1.3 — Postholder Responsibility.
CAP 3037 hard-links logistics compliance to MOE chapter-specific obligations, ensuring traceability during audits.
