Inadequate CAA regulatory oversight of aviation safety

Pin Get email alerts Request correction

First reported 2 Feb 2016•Latest report 2 Aug 2024

Definition

What this concern includes

Includes failures in the CAA's aviation-safety oversight and regulatory-control function, including inadequate investigative or enforcement powers and failure to regulate or publish effective safety guidance or requirements for aviation activities.

Not included

  • Excludes aviation hazards or operational failures where the CAA's regulatory-oversight function is not the deficient control.
  • Excludes airworthiness inspection and certification controls where the specific concern is the separate airworthiness regime rather than wider CAA oversight.
  • Excludes planning-authority failures concerning tall buildings or obstacles unless the assertion specifically identifies a CAA regulatory-oversight deficiency.
  • Excludes public warnings, pilot competence and individual flight conduct where no failure of CAA regulation, guidance, investigation or enforcement is asserted.

    Report summary

    On 25 June 2023, Peter Gregory was fatally injured when the home-built hot air balloon he was piloting suffered a parachute stall during a rapid ascent in a competition race and descended rapidly to the ground. Concerns related to the possible contribution of the balloon’s design to the stall, the absence of CAA guidance on amateur-built balloons, and the lack of CAA regulation or guidance for the safe oversight of competition balloon flying in the UK.

    Failure of CAA oversight for competition balloon flying in the UK

    Wider context from the report

    “2) The inquest also heard evidence that the CAA currently neither regulates, nor publishes guidance for the safe oversight of competition balloon flying in the UK. Whilst there is guidance published by the British Balloon and Airship Club ( BBAC ), the BBAC is a sporting body and not a regulator, and therefore does not have the power, for example, to ground a balloon which does not conform to its published guidance. ”

    Lack of CAA guidance on the design, testing and inspection of amateur-built balloons

    Wider context from the report

    “1) The inquest heard evidence from an investigator at the Air Accidents Investigation Branch ( AAIB ) that Mr. Gregory’s balloon was home-built, based on a design produced by a friend and fellow balloon pilot, and that the balloon’s design ( in particular, the location of the balloon parachute’s centralising lines, which determine its height within the balloon envelope ) may have played a part in the parachute stall which led to the balloon’s sudden and fatal descent. The inquest also heard that the AAIB has recommended that the Civil Aviation Authority ( CAA ) publishes guidance on the design, testing and inspection of amateur-built balloons to reduce the risk of accidents due to unsafe conditions such as parachute stall, but that it is up to the CAA whether or not to regulate the design and construction of amateur/home-built balloons; ”

The CAA has previously published a mandatory Safety Directive (SD) (SD-2021/004: Non-Part 21 Amateur-Built Balloon and Airship Operational Limitations | UK Civil Aviation Authority) for amateur or home-built balloon limiting volumetric size of balloon envelope and occupancy, in keeping with the intent that these aircraft are for recreational, rather than for commercial use.”

    Insufficient CAA powers for investigating and enforcing aviation regulation breaches

    Wider context from the report

    “2. I have concerns with regard to the following: i. There could be future deaths as a result of these illegal flights, and I request that the Secretary of State for Transport conducts a review of the powers available to the CAA in investigating breaches of aviation regulations. I request that the Secretary of State for Transport consider meeting with the CAA to establish what powers they would find of assistance in their investigative and enforcement role. ii. I further request that a review is undertaken by the Secretary of State for Digital, Culture, Media and Sport of the guidance given to the general public, especially all those involved in the sporting and music worlds, about the illegality of these flights and the risks associated with them. I would again request that consideration be given to meeting with the CAA who can properly advise on the risks associated with these flights, especially of future deaths that can occur and what support may assist them in deterring people from using these flights. iii. I would request that all the organisations identified at numbers 3-20 in the list at the beginning of this report, consider cascading to all their members, and anyone else they consider will benefit from the information, the illegality of these flights and the risks associated with them, especially of a future death, in order to discourage the use of these flights. I would again request that consideration be given to liaising with the CAA who can properly advise on the risks and what support would be of benefit to reduce the use of these flights and prevent future deaths. ”

    Report summary

    On 13 March 2014, four men were travelling in an Augusta Westland AW139 helicopter when it impacted the ground near Gillingham, Norfolk, in dark and foggy conditions. All four died from their injuries. The principal concern was that regulations governing visibility and take-off conditions applied to commercial departures from licensed aerodromes but not to this non-commercial departure from an unlicensed aerodrome, despite a previous accident in similar circumstances.

    Lack of equivalent regulation for non-commercial departures from unlicensed aerodromes in limited visibility

    Wider context from the report

    “(1) On the 13 March 2013 at the time of take-off, it was dark and there was fog. Visibility was therefore limited. There are Regulations in place which would have prevented a take-off in these conditions had this been a departure from a licensed aerodrome and had this been a commercial venture. (2) Because this was a departure from a non-commercial venture and take-off was from an unlicensed aerodrome, the Regulations do not apply. (3) It is understood there was an accident in the 1990s in similar circumstances and operating under private category rules, as a result of which the Irish Air Accident Investigation Unit (AAIU) published a report and noted that "The flight used a navigation approach procedure that would not meet the standards required by the UK Authorities for public transport operations. However, this was not illegal because the flight was operated under private category rules". (4) The AAIU made recommendations including that “The UK CAA should consider the establishment of a special category for the operation of corporate aviation”. It is understood this recommendation was accepted but no special category was established. Guidance was provided but not regulation. (5) New European aviation legislation affecting the non-commercial operation of aircraft will come into effect in the UK from 25 August 2016 which will introduce new regulations for the management and operation of this type of aircraft. (6) It is understood the CAA has decided a broader and deeper review of Instrument Flight Rules suite controlled airspace in general is necessary and that a project plan is being developed to address the issues, develop recommendations and suggested courses of action. There is liaison with the European Aviation Safety Agency “in taking forward any such changes”. (7) It is of concern that despite the previous accident in the 1990s and this accident, a departure from a non-commercial venture and an unlicensed aerodrome is not covered by the equivalent regulation as a departure from commercial and licensed premises. ”

In addition, and following other safety recommendations relating to both helicopter and aeroplane accidents, we have instigated a thorough review of the rules applicable to flights being performed under Instrument Flight Rules (IFR) outside controlled airspace through our Safety Review Committee. This will cover several of the issues raised in relation to this accident as well as the wider context of current and emerging practices and is scheduled to be completed by 30 September 2016.”

This is the first time that such measures have been applied under law and will require operators to meet stringent standards including having an accountable manager, an effective management system and procedures properly documented in their own operations manual detailing how all flights are to be managed and flown. The CAA will be required to conduct oversight of these organisations to ensure that they are compliant with the regulations. This is a level of contact that has not hitherto been required but is expected to help identify and better manage the risks in this sector of aviation.”
