FOD incidents cut with AS9100 tool-for-tool control.
A global airline MRO division needed tool-for-tool accountability and FOD prevention across four line stations and the apron.

What they were up against.
FOD risk on line and apron
Foreign-object-debris risk threatened safety and incurred costly inspections.
Manual tool accountability
Tool control was manual, slow, and hard to audit to AS9100.
GSE went missing
Ground support equipment was lost and under-utilised across the apron.

Independent, tied to a named KPI.
We delivered AS9100 tool-lifecycle control with UWB on the line during heavy maintenance, plus GPS and RFID for GSE on the apron, integrated to SAP S/4HANA.
What the engagement delivered.
- UWB tool control during heavy maintenance visits
- FOD-prevention controls across four line stations
- GSE tracking on the apron, integrated to SAP S/4HANA
Results in this engagement
The stack behind it
Baseline, method, period and what we excluded.
This page describes an engagement our advisers led in earlier roles. The client name is withheld under NDA. Figures are as reported at the time, with published industry sources where noted.
- Baseline: FOD walks and manual tool-for-tool checks; incidents logged after the fact.
- Method: AS9100-aware tool-for-tool control with RFID; FOD event rate measured against pre-programme baseline.
- Period: Production line segment through a full audit cycle.
- Excluded: Industry-generic FOD reduction percentages presented as this line's measured result without a baseline window.
Programme context
Tool control for FOD prevention centres on crib cabinets, portals and work-order assignment. AS9100 audit evidence is a first-class requirement.
Expand from calibrated critical tools to kits once discipline sticks.
Outcomes in this engagement and how they were earned
Outcomes: fewer missing-tool events, faster pre-close checks, stronger audit packs.
Lessons from this engagement
Lessons: negative evidence (not returned) matters; on-metal tagging; hangar RF survey; no RFID without FOD procedure ownership.
Deeper problem framing
Missing tools threaten FOD events and audit findings. Paper cribs lie under time pressure.
Approach
Cabinets/portals; work-order assignment; negative evidence alerts; calibration interlock; AS9100 evidence design.
Outcomes and measurement
Missing-tool events, pre-close check time, audit retrieval.
Governance, risk and what we refuse to claim
Figures from this engagement only. Your payback depends on adoption, integration quality and exception labour, not tag unit cost. Named references under NDA on engagement.
We challenge any supplier who asks you to accept demo-day averages as production truth.
Implementation sequence and change management
Critical calibrated tools first; cabinet/portal design; work-order assignment; negative-evidence alerts; FOD board ritual ownership. Audit-pack rehearsal before scale.
KPIs: missing-tool events, pre-close delays, retrieval time for auditors.
Buyer checklist, supplier challenges and engagement shape
For FOD tool control, require negative-evidence alerts and calibration interlocks in the same design.
Buyer checklist before you sign: (1) written system of record for events; (2) acceptance tests with 95th-percentile performance under real interference; (3) integration owner named in IT/OT; (4) privacy or labour consultation path if people are tagged; (5) cybersecurity zoning sketch; (6) five-year TCO including batteries, spares, recalibration and SLA escalations; (7) exit/export terms so you are not hostage to a cloud tenant; (8) a pilot that can fail without political punishment.
Supplier claims to challenge in this pattern: brochure accuracy without production load; 'compliance included' without artefacts; ROI that assumes perfect adoption in 30 days; references that cannot be called under NDA; install partners who have never worked your vertical's overlays; shared support accounts; and any design that dumps locating onto a flat plant or clinical VLAN.
How TRACIO typically engages: stage-1 architecture and measurement design; independent shortlist and RFP language; pilot acceptance criteria; then optional implementation oversight or programme rescue if a prior pilot stalled. We don't sell hardware, so our advice stays independent. Pages like this one exist so you can prepare the workshop. Your numbers replace every planning band when we model payback.
Risk register themes that recur: mute fatigue on alerts; shadow spreadsheets reappearing beside the platform; battery logistics understaffed; master data too weak to support identity; works-council or IG review starting too late; and success declared on demo day before night-shift reality.
Document baseline windows explicitly: what you measured, for how long, which shifts, and what you excluded. Investment committees and auditors both punish fuzzy before/after stories. If your baseline is weak, spend two to four weeks fixing measurement before ordering anchors or portals. That discipline is cheaper than a stranded deployment and is the difference between a locating programme and a technology souvenir.

Hangar & MRO reality
Independent advisory means the radio is chosen last. After the job, the constraints and the system of record are clear.
Tool control that survives a turnaround
Map FOD risk, calibrated-tool custody and hangar flow before a radio is chosen.
Independent, aviation-grade
Shortlists respect on-metal tags, hangar RF and the MRO system already running, not a partner programme.
Integrate to the maintenance record
Events land in the system engineers already trust so accountability outlives the pilot.
Measurement
Baseline: crib variance, missing-tool / FOD incidents, and kit-build time. Pilot: one crib or bay with RFID/RTLS accountability vs the existing crib system. Steady-state: crib accuracy, kit-build time, and FOD investigations tied to tooling. Figures are as reported in this engagement.
