What Airworthiness really means and why it matters more than ever.

Airworthiness is more than compliance. It is not just paperwork, a checklist, or a tick in a box. It is the confidence that an aircraft can do what it is designed to do safely, reliably, and repeatedly, in a complex and changing world, where Assurance has never mattered more.

At SQEP, we do not just interpret Airworthiness standards – we live them! Over 70% of our team served in the Armed Forces, bringing frontline experience from one of the most rigorous Airworthiness environments throughout the world. It is this lived understanding that shapes the SQEP approach.

Airworthiness is typically broken down into two key components:
• Continuing Airworthiness
• Initial / Type Airworthiness

SQEP Ltd provides support across all the facets of Airworthiness, working alongside both Military and Civilian regulated clients.

Initial / Type Airworthiness

From full aircraft certification to type design change / modification programmes and projects, our team can provide complete end-to-end support. Some of our clients include: the MoD DE&S, Boeing, Boeing Defence UK, Lockheed Martin, KBR, Thales, NATO, General Dynamics, Spirit, Callen Lens, and QinetiQ.

The key elements that we support, include:

  • Compliance with Design Standards – Ensures the aircraft meets the applicable Military or Civil design standards or specification (e.g. EASA Certification Specifications, FAA Federal Aviation Regulations, Defence Standard 00-970).
  • Type Certification / Military Type Certification – Is issued by a Regulator when an Air System design meets all its Airworthiness requirements. In the case of a Military context where there are non-compliances, SQEP build the technical arguments to help manage risk – this underpins risk acceptance and approval.
  • Design Assurance and Control – Application of systems engineering validation and verification principles, to ensure the integrity of design.
  • Safety Assessment – Conducting Functional Hazard Assessments (FHA), Failure Mode and Effects Analysis (FMEA), and Fault Tree Analysis (FTA).
  • Configuration Management – Managing changes to the design, ensuring audit traceability.

“Initial / Type Airworthiness is fundamental to the Assurance of aircraft or airborne equipment, and getting it right takes extensive knowledge, experience, judgement, and rigour – especially when lives are at stake.” Alan Bassett, Head of Airworthiness & Certification, SQEP
