Sofema Online (SOL) www.sofemaonline.com considers the proposed action to improve aviation safety by making System Safety Assessment (SSA) Certification requirements more comprehensive and consistent.

Details of Proposed Change

The FAA proposes revised and new safety standards to reduce the likelihood of potentially catastrophic risks due to latent failures in critical systems.

>> The standards would require the elimination of such risks as far as practical. When it is not practical to eliminate such a risk, the standards would require the reduction and management of any remaining risk.
>> The proposed standards would also improve the likelihood that operators discover latent failures and address them before they become an unsafe condition, rather than discovering them after they occur and the FAA addressing them with airworthiness directives (ADs).

Sofema Online (SOL) www.sofemaonline.com considers the key aspects of the CCA process

Common Cause Analysis

Common Cause Analysis (CCA) describes the method used to identify the potential for common-cause failures (CCFs) within a system, where multiple components fail simultaneously due to a single event or shared cause.

In the context of certification, a comprehensive CCA is crucial. Regulatory bodies require a systematic approach to identifying and mitigating safety risks, including CCFs. Therefore, demonstrating a rigorous CCA is often a requirement for certification of an aviation flight control system

>> Barely Visible Damage (BVD)
>> and Externally Non-Visible Damage (NVD).

Introduction

Composite materials typically do not don’t show damage in the same way metals do. Additionally, composites are susceptible to hidden cracks and defects that may occur during manufacturing or service.

Sofema Online (SOL) www.sofemaonline.com considers the use of the ICAO 5 x 5 Matrix as a Risk Assessment Tool.

Introduction

ICAO 5 x 5 Risk Assessment is a widely used risk assessment methodology in the aviation industry. It involves the assessment of the likelihood and severity of a potential risk and assigning a score to each based on a five-point scale. The scores are then multiplied to give an overall risk score.

Sofema Online (SOL) www.sofemaonline.com considers the role of CPCP ADs and the responsibility for updating the Aircraft Maintenance Program (AMP)

Introduction

Each CPCP, whether originally mandated by AD or later incorporated into the MPD for an aircraft, includes certain definitions to lay the groundwork and baselines for the programs.

Corrosion is a progressive condition and generally becomes more serious as it moves deeper into the grain of the affected metal. Therefore, different levels of corrosion are defined: Level 1 being the least serious, Level 2 being increasingly problematic, and Level 3 being the highest. However, these definitions were never standardized, although they are largely well-understood by CAAs, manufacturers, and the industry.
