Concealment or Misclassification of Non‑Conformances to Avoid MRB Scrutiny

3 verified sources

Definition

Aerospace quality literature stresses the need for *identifying and reporting all* non‑conformances and maintaining objective evidence, implying the known risk that issues may be under‑reported when systems are weak.[7][2] Inadequate controls around NCR logging and MRB approvals can enable misclassification or informal fixes outside the formal process, shifting risk into the field and masking true quality cost.

Key Findings

  • Financial Impact: Difficult to quantify, but potential exposure includes hidden rework cost, warranty and field‑failure cost, and regulatory actions when concealed non‑conformances emerge.
  • Frequency: Ongoing risk where incentives and controls are misaligned
  • Root Cause: Pressure to meet production schedules, lack of automated traceability, and weak segregation of duties in NCR/MRB workflows can encourage bypassing formal MRB for "minor" deviations.[7][8] Absence of integrated audit trails and data analytics makes systematic under‑reporting or mis‑routing of NCRs harder to detect.

Why This Matters

This pain point represents a significant opportunity for B2B solutions targeting Aviation and Aerospace Component Manufacturing.

Affected Stakeholders

Production supervisors, Quality inspectors, MRB engineers, Supplier quality engineers, Program managers

Financial Impact

$100K-$250K (hidden supplier quality failure cost, future recurrence of same defect from supplier, customer audit finds undocumented rework) • $120K-$300K (in-service failure, customer warranty claim, FAA audit finding if discovered) • $150K-$350K (rework cost + risk of field failure, warranty exposure, regulatory audit)

Current Workarounds

Config Mgr and Mfg Eng agree to 'note for next build'; current assembly released with discrepant revision; no NCR generated; no formal MRB • Config Mgr consults with PM and Quality; team agrees supplier made 'valid equivalent substitution' and part is acceptable; no formal NCR; no design review; blade integrated into engine • Config Mgr researches parts history manually; no formal NCR initiated; adapter approved for integration under 'historical use precedent'; no formal qualification review

Related Business Risks

High Cost of Non‑Conforming Parts and MRB Decisions Consuming Up to 20% of Manufacturing Cost

Up to 20% of total manufacturing cost on affected programs, on an ongoing basis

Production Bottlenecks and Line Stoppages from Slow Non‑Conformance Investigation and MRB Disposition

Implicitly several percentage points of throughput lost; non‑conformance management cited as consuming up to 20% of manufacturing cost, which includes production delays and idle capacity.[1][6]

Lost Billable Recovery and Missed Chargebacks for Non‑Conforming Supplier Parts

Embedded within the up to 20% of manufacturing costs spent on non‑conformance management; a material fraction is potentially recoverable from suppliers/customers but often not fully billed due to poor data and processes.[1][7]

Overtime, Scrap, and Rework Cost Overruns Driven by Inefficient Non‑Conformance and MRB Processes

Up to 20% of manufacturing cost, with documented ~30% reduction in non‑conformance rates (and associated costs) after process improvements, implying substantial recurring prior overruns.[1][6]

Delayed Shipments and Cash Collection from Late MRB Dispositions and Investigations

Not quantified industry‑wide, but embedded in the 20% of manufacturing costs and evidenced by case reports of schedule delays prior to non‑conformance process improvements.[1][6]

Regulatory and Certification Risk from Inadequate Non‑Conformance and MRB Controls

Potentially millions in exposure through findings, required corrective actions, increased oversight costs, and delivery disruptions; not always itemized, but recognized as a major risk area tied to non‑conformance management.[1][7]
