SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill eliminates the risk of regulator-rejectable aviation safety paperwork for management of change (MoC) requests, which often lacks specific hazard identification, hierarchy-of-controls-aligned mitigations, and documented approve/decline rationale required by ICAO Annex 19.

Core Features & Use Cases

  • Structured Intake Workflow: Forces specificity by asking one question at a time to capture the named operator, exact change details, new/changed hazards, and approval authority, refusing to proceed on vague or incomplete requests.
  • ICAO 5x5 Risk Scoring: Uses the shared A7 risk matrix engine with the official ICAO 5x5 MatrixConfig to score hazard risk reproducibly, eliminating inconsistent or forked risk matrices.
  • Hierarchy of Controls Mitigation: Ranks all mitigations through the full elimination-to-PPE hierarchy, flagging unjustified PPE/admin-only treatments, and validates all action owners and target dates via smart_actions.
  • Mandatory De-identification: Scrubs all personal and health identifiers from inputs before drafting, pseudonymizing data by default and aggregating small cell counts to protect sensitive information.
  • SME Review Gate: Runs a domain-expert aviation MoC safety assessor sign-off before presenting any output, ensuring all regulatory requirements are met and no de-identification leaks occur.
  • Use Case: An aviation safety manager can use this Skill to assess the safety of adding a new hot-and-high destination to their network, identifying new hazards like unstabilised approaches, scoring their risk, proposing higher-order mitigations, and producing a documented approve/decline decision with rationale for the CAA.

Quick Start

Use the aviation-change-safety-assessment skill to assess the safety of a specific operational, procedural, fleet, or organizational change for your named aviation operator, airport, or AMO by answering the structured intake questions and receiving a compliant, de-identified MoC assessment with 5x5 risk scores and approve/decline rationale.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I conduct an ICAO Annex 19 management of change safety assessment?

An ICAO Annex 19 management of change safety assessment requires identifying new or changed hazards, scoring risk using a 5x5 matrix, ranking mitigations by hierarchy of controls, and documenting approve/decline decisions with recorded rationale for aviation operators.

What is the hierarchy of controls in aviation safety risk management?

The hierarchy of controls in aviation safety risk management ranks mitigations from elimination down to PPE. An effective assessment flags unjustified PPE or admin-only treatments, ensuring higher-order controls are prioritized to reduce hazard risk during operational changes.

Can I use a 5x5 risk matrix for aviation SMS management of change requests?

Yes, a 5x5 risk matrix can be used for aviation SMS management of change requests to score hazard risk reproducibly. Standardized ICAO matrix configurations eliminate inconsistent scoring across operational, procedural, fleet, or organizational changes.

Does an aviation change safety assessment require de-identification of data?

Yes, aviation change safety assessments require mandatory pre-draft de-identification of personal and health identifiers. Data is pseudonymized by default and small cell counts are aggregated to protect sensitive information before drafting safety documentation.

What is the best way to document an MoC approve/decline decision for a CAA audit?

The best way to document an MoC approve/decline decision for a CAA audit is to generate a branded report containing recorded rationale, 5x5 risk scores, and hierarchy-of-controls mitigations. This satisfies ICAO Annex 19 regulatory compliance requirements.

When do I need SME review for an aviation management of change risk assessment?

You need SME review for an aviation management of change risk assessment as a mandatory pre-output gate. A domain-expert assessor must sign off to verify regulatory requirements are met and ensure no de-identification leaks before presenting final documentation.
