Full title and description

SAE ARP5150A-2019 — Safety Assessment of Transport Airplanes in Commercial Service. A SAE Aerospace Recommended Practice that provides guidance, methods and tools to perform ongoing safety assessment activities for transport-category airplanes in commercial service, intended to support an operator's safety management program and demonstrate compliance with regulatory and internal safety requirements.

Abstract

ARP5150A-2019 outlines a structured process for ongoing safety assessment of transport airplanes after entry into service. It defines objectives, inputs, methods (qualitative and quantitative), data sources, hazard identification and risk analysis approaches, tracking and corrective-action practices, and performance indicators to sustain and improve in-service safety. The document focuses on the question “Is it safe?” for continued operations and provides practical guidance for operators, manufacturers and maintainers to detect, assess and mitigate safety issues in-service.

Scope

Provides guidelines for the ongoing safety assessment process for transport airplanes in commercial service. The scope covers functions and methods to identify safety issues, analyze risk, monitor safety performance, implement corrective actions and document outcomes. It is intended for organizations operating, supporting or regulating transport-category airplane fleets and is compatible with broader safety management systems and airworthiness regulations; it does not prescribe a single organizational structure or address economic decision criteria in depth.

Key topics and requirements

• Framework for an ongoing safety assessment process integrated with an operator's safety management system (SMS).
• Sources of safety information: flight data monitoring, service difficulty reports, maintenance data, occurrence reports, manufacturer data, and operational feedback.
• Hazard identification and prioritization methods tailored to in-service operations.
• Risk assessment techniques (qualitative and quantitative) and guidance for assigning acceptability and mitigation priorities.
• Definition and use of safety performance indicators (SPIs) and targets to monitor continuing airworthiness.
• Corrective-action development, implementation tracking, and closure criteria.
• Documentation, recordkeeping and evidence to support regulatory compliance and internal assurance.
• Guidance on tools, models and data-analysis practices used in ongoing safety assessment.

Typical use and users

Used by airline safety managers, continuing airworthiness organizations, aircraft manufacturers and OEM support teams, maintenance and engineering organizations, civil aviation authorities, and consultants involved in in-service safety assurance. Typical applications include establishing or improving in-service safety assessment processes, investigating recurring events, setting SPIs/SPTs, prioritizing fleet corrective actions, or preparing evidence of ongoing safety to regulators.

FAQ

Q: What is this standard?

A: ARP5150A-2019 is an SAE Aerospace Recommended Practice titled "Safety Assessment of Transport Airplanes in Commercial Service" that provides guidance and methods for ongoing in-service safety assessment of transport-category airplanes.

Q: What does it cover?

A: It covers the processes, data sources, analysis methods, performance monitoring and corrective-action practices used to identify and control safety issues for airplanes in commercial service. It focuses on the "Is it safe?" aspect of ongoing safety management rather than organizational structure or economic decision-making.

Q: Who typically uses it?

A: Airlines, continuing airworthiness and maintenance organizations, aircraft OEMs, safety engineers, airworthiness authorities and consultants use it to design or improve in-service safety assessment programs and to support regulatory compliance and internal assurance.

Q: Is it current or superseded?

A: The ARP5150A revision was published January 2, 2019. As of that revision it is the current SAE ARP5150A edition. Users should check the SAE publication listings or their national body for any updates or subsequent revisions after 2019.

Q: Is it part of a series?

A: Yes — ARP5150A complements related SAE guidance on safety assessment and aircraft/system development (for example ARP5151A for general aviation, ARP4754A/B for systems development and ARP4761 for system safety assessment). It is commonly used with ICAO and national SMS/continuing-airworthiness guidance.
