Sofema Online (SOL) www.sofemaonline.com considers the role of a Functional Hazard Assessment as part of the Aircraft Type Certificate Certification Process.

Introduction

A Functional Hazard Assessment (FHA) is a systematic evaluation conducted to identify and assess potential hazards associated with the functions and behaviours of a system or process. It is common to ensure safety and mitigate risks.

>> The FHA focuses on analyzing the functional aspects of a system to identify potential hazards and their potential consequences.

Introduction

Operational Suitability Data (OSD) refers to a suite of data which is required to be established by aircraft manufacturers under the control and oversight of EASA Part 2. OSD is considered as Data which is important for the safe operation of aircraft type.

Sofema Aviation Services (SAS) www.sassofia.com considers in detail the forthcoming changes to Initial Airworthiness Regulation 748/2012, their applicability, and regulatory obligations.

Introduction - Commission Delegated Regulation (EU) 2022/201

This regulation applies to management systems and occurrence-reporting systems to be established by design and production organisations.

Ref also EASA Basic Regulation (EU) 2018/1139 and (EU) No 376/2014

Sofema Online (SOL) www.sofemaonline.com considers the function of evaluation board and operational suitability data related to FAA & UK CAA Type Certification.

Introduction UK CAA Evaluation Process

The UK CAA system (derived from EASA) includes, under the type certification process, an approval of data that are considered necessary for the safe operation of an aircraft, called the Operational Suitability Data (OSD).

» These data, once approved, are attached to the TC through a reference in the TCDS and owned by the TC holder.

Introduction by Sofema Online (SOL) www.sofemaonline.com

The following abbreviated notes provide a summary of the key events related to the EASA Type Certification Process.

Type Certification

 A type certificate is an approval made by a regulatory authority that an aircraft is manufactured according to an approved design, and that the design ensures compliance with airworthiness requirements.

• The type certificate (TC) implies that the aircraft is manufactured according to the approved design and can be issued an Airworthiness Certificate.
• To meet airworthiness requirements, the aircraft, related products (engine and propeller), parts, and appliances must be approved.
• Within the European Union (EU), implementation rules for type certification are laid down by the Commission Regulation (EU) No 748/2012 of 3 August 2012.

Note - A Type Certificate is not an Airworthiness Certificate.

Sofema Online (SOL) (www.sofemaonline.com) considers the key elements related to the EASA Type Certificate & Restricted Type Certificate

Introduction

Requirements for the issuance of a type certificate or restricted type certificate - Ref 21.A.21(EU) 2019/897)

In order to be issued a product type certificate or, when the aircraft does not meet the essential requirements of Annex II to Regulation (EU) 2018/1139 an aircraft restricted type certificate, the applicant shall:

• Demonstrate its capability in accordance with point 21.A.14
• Comply with point 21.A.20
• Demonstrate that the engine and propeller, if installed in the aircraft:

° Have a type-certificate issued or determined in accordance with this Regulation; or
° Have been demonstrated to be in compliance with the aircraft type-certification basis established and the environmental protection requirements designated and notified by the Agency as necessary to ensure the safe flight of the aircraft
