The Material Review Board (MRB) is the formal, cross-functional disposition process for any part or lot that fails inspection against engineering requirements. Every nonconformance gets one of four dispositions — use-as-is, rework, scrap, or return-to-supplier — decided jointly by quality and engineering, never by the inspector or operator who found it.
Why a board, not one person: a rework or use-as-is disposition is an engineering judgment call about whether a part still meets its design intent for flight — it requires both the authority to approve a deviation and the traceability to prove it was reviewed, not delegated to whoever is fastest to sign off.
MRB Composition (this program)
| Role | Program Assignee |
|---|---|
| MRB Chair (Quality) | J. Ferraro (Phase 2) / R. Kessler (ad hoc, Phase 1 FAI-only cases) |
| Engineering representative | M. Osei (Manufacturing Engineering) |
| Customer representative (as required) | Meridian source inspection, for major/structural dispositions only |
MRB Log
| ID | Date | Nonconformance | Disposition | Owner | Status |
|---|---|---|---|---|---|
| MRB-001 | 2026-02-11 | Edge-trim dimension out of tolerance, 2 of 8 panel positions, S/N 0001 (FAI unit) | Rework | R. Kessler / J. Ferraro (Chair, ad hoc for FAI) | Closed — reworked panel passed re-inspection |
| MRB-002 | 2026-04-03 | Minor surface porosity within cosmetic (non-structural) zone, S/N 0034 | Use-as-is | J. Ferraro | Closed — engineering disposition, no structural impact |
| MRB-003 | 2026-05-19 | Fastener hole diameter 0.003in over tolerance, single hole, S/N 0058 | Rework | J. Ferraro | Closed — oversized fastener installed per engineering approval |
| MRB-004 | 2026-06-02 | Composite ply misalignment detected via NDT, S/N 0071 | Scrap | J. Ferraro | Closed — part scrapped, root cause traced to layup fixture wear |
| MRB-005 | 2026-06-20 | Raw material certification missing batch traceability code, incoming lot | Return-to-Supplier | S. Pham | Closed — lot returned, replacement lot certs verified before use |
MRB-001 is the FAI nonconformance also described on the First Article Inspection page. MRB-004's root cause (layup fixture wear) was fed back into Lessons Learned and triggered a preventive-maintenance schedule for production fixtures.
