Consultation on Amendments to UK Reg (EU)139/2014 and CAP 168

Overview

Recent operational experience across the UK aviation sector has highlighted a growing safety and capacity-related issue concerning the acceptance of diverted aircraft at aerodromes. Periods of disruption particularly during adverse weather, airspace constraints, or network congestion have exposed inconsistencies in aerodrome preparedness and diversion handling capability.

To address this, the CAA proposes regulatory enhancements to strengthen safety, improve operational resilience, and ensure greater clarity regarding aerodrome obligations in diversion scenarios.

The CAA proposes amendments to Acceptable Means of Compliance (AMC) and Guidance Material (GM) to UK (EU) Regulation No. 139/2014 and CAP168.

The Secretary of State makes the final decision whether to implement CAA’s proposed changes to the regulations, and the final wording of the regulations. 

The proposed wording of the regulations in this consultation may well change if and when the Secretary of State decides to amend the regulations. 

Why your views matter

It is important to the CAA that everyone has an opportunity to voice their opinion on matters that could affect them. For this reason, we are asking for comments on these proposed changes.

We welcome comments from every sector of the community. This includes the general public, government agencies and all sectors of the aviation industry, whether as an aviator, aviation consumer and/or provider of related products and services.
