Part 145 evidence, line-stamped at the work card.
Aviation MRO operates under FAA 14 CFR Part 145 and AS9110D — with line-stamped work cards, RII inspections, personnel currency at every signature, and traceability that has to reproduce years after the work was performed. Your internal certificate posture sits under AS9110D, your Part 145 air-agency certificate, and — increasingly — a 14 CFR Part 5 SMS expansion. Your customers (airlines, lessors, military operators) run audits referencing customer-specific CASS / OpSpecs and program-specific quality regimes. Wēlr is the work-card record that's also the audit record — with the personnel surface (A&P / IA currency, type training, OJT, stamp control) on the same evidence model as the execution.
Four pains the FAA inspector will surface.
- 01
Work cards reconciled to the logbook after sign-off.
Execution lives on paper or in a tablet app; the logbook entry happens later, in a separate workflow. The link between the technician's signature and the entry the regulator inspects is built by hand — and the audit trail has a join.
- 02
RII inspection sign-offs live outside the execution record.
Required Inspection Items get a second signature in a separate system from where the step was executed. The procedure step and the inspection sign-off live apart — and the assessor finds the join.
- 03
A&P / IA currency and recurrent training tracked on a spreadsheet.
Technician certification expirations, type training currency, recurrent intervals, and OJT records live on a spreadsheet that gets rebuilt overnight when the FAA PMI asks for the matrix. Stamp control across shifts is enforced by SOP, not by the system that authenticates the signature — and personnel currency is consistently a top driver of recent enforcement actions.
- 04
AD and SB compliance across the fleet is a multi-week reconciliation.
Airworthiness directives and service bulletins land continuously; compliance status across the fleet is reconciled by spreadsheet when the next audit comes up — not maintained continuously.
Four primitives. One Part 145 record.
Line-stamped work-card execution
Every step signed in-band, with authentication tied to the technician's qualification record. The logbook entry is the same record as the execution — no reconciliation, no later workflow.
RII inspection in the procedure record
Required Inspection Items are first-class steps with a second-signature gate enforced at the API. The audit reads top-to-bottom on one screen; the inspector sees the procedure context the inspection signed against.
Technician qualification record + dispatch-time currency check
Certification (A&P, IA, type), recurrent training, OJT, and stamp control live as first-class attributes on the technician record. Dispatch fails closed when currency lapses. The qualification matrix the FAA PMI asks for is a query against the system, not an overnight spreadsheet rebuild.
Cross-fleet AD / SB dashboard
Airworthiness directives and service bulletins are work items attached to the affected fleet. Compliance status, deadline, and accomplishment evidence live on one record — surfaced continuously, not at audit time.
Why not extend the MRO software you already run?
Most Part 145 organizations run paper plus a CMMS, or a generic MRO platform that pre-dates the line-stamp-at-the-step audit pattern. Both keep execution, logbook, and the personnel record in different worlds. Wēlr collapses them onto one record.

|---|---|---|---|
| Line-stamped work card = logbook entry | Same record | Reconciled after sign-off | Logbook bolt-on |

One work card. Execution, RII gate, personnel currency, and logbook — same record.
When the FAA PMI asks for the work card that found the LE blade nick on N145WL last March, you don't switch systems. The technician's currency-verified setup check, the borescope insertion, the finding (EMM 72-31-00), the RII gate (customer's CASS reference), the inspector's second signature, and the logbook entry — all live on one timeline. The audit reads top-to-bottom in three minutes — not three days of reconciliation, and not a separate trip to the training matrix spreadsheet.

If any of these are true, we should talk.
- ✓Your technicians sign work cards in one system and the logbook entry happens in another workflow after sign-off.
- ✓Required Inspection Items get their second signature in a different system from where the step was executed.
- ✓Your tool calibration runs on a calendar, not on duty cycle or environmental exposure.
- ✓AD or SB compliance across your fleet is a multi-week reconciliation when the regulator asks for it.
- ✓An FAA / EASA inspection or customer airline audit found a gap the team traced to a work card that couldn't reproduce the original execution context.
