Technician Authorization
A high certification match or availability ranking above is a recommendation, not authorization — this table is the formal authorization determination and always takes precedence. A hard authorization block is never overridden by a strong recommendation.

Evidence
Prototype storage only — images are held as in-browser object references for this session and are not persisted to production object storage. Uploading a photo records that an artifact was captured; it is never treated as proof of airworthiness, compliance, or acceptable workmanship on its own.
Required execution evidence has not been submitted for this task.

Maintenance Task & Release
Technician completion is separate from release. "WAITING PARTS" describes the work order status; the execution state below tracks whether this work order has actually cleared inspection and is ready for release.
Traceability Chain
- Aircraft: N412MX
- Discrepancy: APU starter motor showing elevated starting current, pending replacement. (MEDIUM)
- Maintenance Task: APU starter motor replacement (serialized rotable) — Insufficient source data (no AD/SB/AMM reference on file)
- Work Order: WO-1054 — APU Starter Motor Replacement
Task Execution
Performed by: Sara Kavanagh (assigned, not yet signed off)
Inspected by: Not yet inspected.
Execution State: BLOCKED
Work is blocked before starting (material or qualification gate open).
| Safety Gate | Status | Reason |
|---|---|---|
| MATERIAL GATE | FAIL | Required material unavailable: APU-410 |
| QUALIFICATION GATE | PASS | A technician is assigned. |
| INSPECTION GATE | FAIL | Independent inspection required before release — eligible inspector(s): Diego Alvarez. The assigned technician cannot inspect their own work. |
| EVIDENCE GATE | UNKNOWN | Authoritative maintenance reference is not available in the current dataset for this task. |
| EXECUTION EVIDENCE GATE | FAIL | Required execution evidence has not been submitted for this task. |
| RELEASE GATE | FAIL | Not yet released — current execution state: BLOCKED. |
Release Readiness
Whether this application's known operational gates are satisfied — not an airworthiness or dispatch determination.
- [MATERIAL] Required material unavailable: APU-410 — Resolve the material shortage (Material Readiness / Procurement). (source: Safety Gate: MATERIAL_GATE)
- [INSPECTION] Independent inspection required before release — eligible inspector(s): Diego Alvarez. The assigned technician cannot inspect their own work. — Assign an eligible independent inspector. (source: Safety Gate: INSPECTION_GATE)
