Walk me through your quality + reliability background.

What it tests: Story arc - engineering / statistics training, AS9100 exposure, FRACAS + supplier work, safety-critical context - because A+D quality interviewers need to see audit-ready discipline from the first answer.

Tell me about a quality or reliability programme you've owned.

What it tests: Programme + closed-loop thinking - scope, audit-trail, outcome - because A+D quality is judged on evidence + sustained improvement, not one-shot fixes.

Why aerospace + defense quality + reliability vs commercial manufacturing or medical device?

What it tests: Authentic alignment - safety-of-flight stakes, audit-trail discipline, decade-scale fleet thinking - because the regulatory + consequence delta is the differentiator.

Why this domain - aviation / space / missiles / electronics?

What it tests: Specificity. Generic answers fail because A+D quality varies a lot across domains (commercial certification vs DoD MIL-STD vs space single-string).

What it tests: Real homework - programme, quality posture, recent events - not generic name-drop.

What's your read on our programme + quality posture?

What it tests: Industry literacy - programme stage, regulatory engagement, recent quality events.

Tell me what you understand about our quality culture + management system.

What it tests: QMS maturity - AS9100 certification, Nadcap scope, independence of quality function, FRACAS deployment.

Walk me through a nonconformance + MRB disposition you led.

What it tests: MRB fluency - use-as-is / rework / repair / scrap reasoning, engineering + customer alignment, AS9100 audit trail.

Quality Reliability interview prep.

Quality engineers, reliability engineers, supplier quality engineers, MRB chairs at primes + tier-1 suppliers (commercial aviation, military, space, missiles, electronics).

What interviewers look for

Can the candidate apply AS9100 QMS discipline + AS9102 FAI + Nadcap fluently across product + process?
Are they fluent in MRB / nonconformance disposition - use-as-is, rework, repair, scrap - with engineering + customer alignment?
Can they execute FRACAS closed-loop + structured root cause (8D / 5-Why / Fishbone)?
Do they understand reliability math - MTBF allocation, MIL-HDBK-217 / Telcordia, FMECA, FTA, HALT / HASS?
Are they fluent in SPC + Cpk / Ppk + MSA + statistical sampling per ANSI / ASQ Z1.4 + Z1.9?
Can they manage supplier quality + source inspection + SCAR + Nadcap special-process oversight?
Are they audit-ready - AS9100, DCMA QAR, FAA / EASA conformity, customer surveillance?

Technical concepts to master

AS9100 QMS + Nadcap

AS9100 structure: ISO 9001 backbone + aerospace requirements - risk-based thinking, configuration management, FAI, counterfeit parts, product safety.
Nadcap special processes: Industry-managed accreditation programme for special processes whose conformity cannot be verified by inspection of the end product alone.
AS9102 First Article Inspection: Documented validation that the production process can produce a part meeting all engineering + design requirements - Form 1 (part), Form 2 (materials + processes), Form 3 (characteristics).
Counterfeit parts mitigation: AS5553 (electronic) + AS6174 (material) requirements to prevent counterfeit / suspect-unapproved parts entering the supply chain.

MRB + nonconformance + FRACAS

MRB (Material Review Board): Cross-functional board (Quality, Engineering, Customer / Airworthiness as required) that dispositions nonconforming material - use-as-is, rework, repair, scrap.
NCR / CAR / SCAR: Nonconformance Report (the issue), Corrective Action Request (internal), Supplier Corrective Action Request (external) - the closed-loop documents.
FRACAS (Failure Reporting, Analysis + Corrective Action System): Closed-loop process capturing field + test + production failures, driving root cause + corrective action + reliability growth.
8D + 5-Why + Fishbone (Ishikawa): Structured root-cause methodologies - 8D is 8-step team-based, 5-Why drills causality, Fishbone organises causal categories (man, machine, method, material, measurement, environment).

Reliability math + test

MTBF allocation + apportionment: Top-down distribution of a system MTBF (or MTBCF / Ao) requirement across subsystems + components - feasibility, complexity, mission-profile weighted.
Prediction methods (MIL-HDBK-217 / Telcordia / FIDES / PoF): Empirical or physics-of-failure prediction of component + assembly failure rate, fed by mission profile + environment.
FMEA / FMECA / FTA: FMEA + FMECA = bottom-up failure mode + criticality. FTA = top-down deductive analysis of undesired events.
HALT / HASS / ALT: HALT = highly accelerated life test (stress-to-failure design margin); HASS = production screen; ALT = time-compressed life test for prediction.

SPC + sampling + MSA

SPC + control charts: Xbar-R / Xbar-S / individuals + moving range / p / np / c / u charts monitor process stability; Western Electric / Nelson rules detect special-cause variation.
Cpk + Ppk + Cp + Pp: Cp / Cpk = short-term (within-subgroup) capability; Pp / Ppk = long-term (overall) performance. Cpk + Ppk account for centring.
Statistical sampling (Z1.4 / Z1.9 / 1916): ANSI / ASQ Z1.4 (attributes), Z1.9 (variables), MIL-STD-1916 (DoD preferred) define sampling plans by AQL + inspection level.
MSA (Measurement System Analysis): Gauge R&R (repeatability + reproducibility), bias, linearity, stability studies validate measurement-system fitness.

Practical drills

A machined titanium fitting on a flight-critical assembly is presented to MRB with a 0.003 inch oversized hole (drawing tolerance +/- 0.002 inch). The customer wants delivery in 5 days for a flight test. Walk through your MRB approach.
A new airborne electronics LRU has a contractual MTBF requirement of 5,000 hours in fighter aircraft environment. The LRU has 4 CCAs - power supply, processor, signal conditioning, I/O. Walk through your allocation + prediction approach.
A tier-1 supplier reports 3 in-service failures of a circuit card assembly in the past 60 days - all traced to solder joint cracking on a particular BGA component. The fleet has 200 units in service. PPAP was approved 18 months ago. Walk through your engineering + quality response.

Smart-question anchors

Programme + production stage - LRIP / FRP / sustainment shaping quality + reliability load
Quality function authority - independent of programme + reporting line to chief quality officer
AS9100 + Nadcap + customer surveillance posture - audit history + Nadcap special processes on-site
DCMA QAR + FAA + EASA engagement - daily oversight model + recent findings
Reliability programme maturity - FRACAS deployment, MIL-HDBK-217 vs Telcordia vs FIDES practice, HALT / HASS adoption
