INVESTIGATION and INQUEST

On 30 June 2023 I commenced an investigation and opened an inquest into the death
of Peter GREGORY. The investigation concluded at the end of the inquest on 1
August 2024

The conclusion of the inquest was that Mr. Gregory “died as the result of an accident”.

CIRCUMSTANCES OF THE DEATH

In answer to the questions “when, where and how did Mr. Gregory come by his
death?”, I recorded as follows:

“On the morning of 25.6.23 a hot air balloon being flown by Peter Gregory, an
experienced balloon pilot, suffered a sudden parachute stall in the course of a rapid
ascent during a competition race. The parachute stall caused the envelope of Mr.
Gregory’s balloon to collapse, and the balloon to descend rapidly to the ground in a
field at Ombersley Court, Ombersley. Mr. Gregory suffered fatal injuries in the
resulting impact, and was confirmed deceased at the scene a short time later that
day.”

CORONER’S CONCERNS

During the course of the inquest the evidence revealed matters giving rise to concern.
In my opinion there is a risk that future deaths will occur unless action is taken. In the
circumstances it is my statutory duty to report to you.

The MATTERS OF CONCERN are as follows.  –

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

1

 to the CAA whether or not to regulate the design and construction of
amateur/home-built balloons;

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.

6

ACTION SHOULD BE TAKEN

In my opinion action should be taken to prevent future deaths and I believe you, as
the Chief Executive of the Civil Aviation Authority, have the power to take such action,
by carrying out a review of the regulation of balloon flying in the UK, considering in
particular whether there should be regulation of the design, construction, inspection
and testing of amateur or home-built balloons, and of competition balloon flying in the
UK.

MR D. D. W. REID – HM SENIOR CORONER FOR WORCESTERSHIRE 

INVESTIGATION INTO THE DEATH OF MR PETER RICHARD GREGORY 

CIVIL AVIATION AUTHORITY RESPONSE TO A REPORT ON ACTION TO PREVENT OTHER DEATHS 

PURSUANT TO REGULATIONS 28 & 29 OF THE CORONERS (INVESTIGATIONS) REGULATIONS 2013 

Introduction 

The UK Civil Aviation Authority (‘CAA’) would first like to express its sincere condolences to the family 
and friends of Mr Gregory. 

The  CAA  is  a  public  corporation,  established  by  Parliament  in  1972  as  an  independent  specialist 
aviation regulator. The CAA works so that: 

• 
• 
• 

• 

the aviation industry meets the highest safety standards, 
consumers have choice, value for money, are protected and treated fairly when they fly, 
through efficient use of airspace, the environmental impact of aviation on local communities 
is effectively managed and CO2 emissions are reduced, 
the aviation industry manages security risks effectively. 

The CAA has carefully considered the Regulation 28 Report to prevent future deaths issued by the 
Senior  Coroner  for  Worcestershire  dated  2  August  2024  (‘the  Report’),  including  the  following 
recommendation that is relevant to the role of CAA: 

… In my opinion, action should be taken to prevent future deaths and I believe you, as Chief Executive 
of the Civil Aviation  Authority,  have  the  power  to take such action, by carrying out a review of the 
regulation of balloon flying in the UK, considering in particular whether there should be regulation of 
the design, construction, inspection and testing of amateur or home-built balloons and of competition 
balloon flying in the UK . 

The CAA was not an Interested Person at this inquest. As such, it did not have access to the inquest 
evidence. When  preparing  this  response, with a view to implementing  further action, the  CAA has 
relied  on  the  information  contained  in  the  Report,  together  with  the  report  published  by  the  Air 
Accidents Investigation Branch (‘AAIB’) into the circumstances of this accident dated 23 May 2024 and 
regulatory information held by the CAA.  

Background to the CAA’s Regulation of the General Aviation Sector 

‘General  Aviation’  is  considered  to  incorporate  all  civil  aviation  in  the  UK  other  than  scheduled 
commercial air transport. Within the CAA, the General Aviation Unit regulates non-complex aircraft 
including microlights, amateur built and historic aircraft, balloons, gliders, piston twins and singles up 
to 5,700kg maximum take-off weight and single pilot helicopters up to 3,175kg. The General Aviation 
Unit is broadly focussed on the regulation of private transport, sport, and recreational flying, including 
civilian air display flying, though it does also include some commercial activity, such as certain flight

 OFFICIAL - Named Parties Only. This information is intended for HM Senior Coroner, CAA and Interested Persons only  

training,  aerial  work  activity,  and  passenger  flying  in  certain  historic  aircraft.  The  CAA’s  statutory 
functions in relation to General Aviation activities are set out in various pieces of legislation: including 
the  Civil  Aviation  Act  2012,  various  assimilated  regulations,  as  well  as  in  secondary  legislation, 
principally, the Air Navigation Order 2016, as amended (‘ANO’). The CAA may only conduct functions 
given to it under, or pursuant to, legislation.  

The  CAA  works  closely  with  those  that  operate  and  conduct  aviation  activities  with  a  view  to 
maintaining high levels of safety performance in civil aviation.  

As with all regulated activities however, the obligation to ensure safety is placed upon organisations 
and individuals that undertake aviation activities, not the regulator. 

Balloons 

Most hot air balloons recorded on the UK civil aircraft register are classified as ‘Part 21’ aircraft.1 This 
means they are issued with a Certificate of Airworthiness by the CAA and with an Airworthiness Review 
Certificate,  which  is  renewed  annually.  These  aircraft  are  subject  to  direct  CAA  airworthiness 
regulation. There are currently 1263 balloons in this category on the UK register. 

There are, in addition to the balloons regulated by the CAA, a smaller number of balloons (69) that are 
not regulated for the purposes of CAA airworthiness oversight and are restricted to recreational or 
private use, rather than commercial operation. These balloons are classified as ‘non-Part 21’ aircraft2. 
In respect of this category of balloons, 54 are amateur constructed balloons. Although these amateur-
built  balloons  are  not  currently  subject  to  CAA  airworthiness  requirements,  they  are  restricted  in 
respect of volumetric size and occupancy. 

Competition balloon flying is not a commercial activity. However, it should also be noted that whilst 
competition balloon flying is not regulated by the CAA, there are competition rules promulgated by 
the British Balloon and Airship Club (‘BBAC’) that should be followed by competitors. These rules are 
based on the Federation Aeronautique Internationale Rules for competition ballooning that are used 
worldwide. The CAA does not currently perform any dedicated oversight of competition balloon flying 
in the UK but does perform periodic general oversight of UK balloon competitions in the same way as 
it does for other types of balloon events. This typically consists of checking aircraft and balloon pilots 
conform to licensing and medical requirements, airworthiness specifications (for Part 21 balloons) and 
adherence to the UK Rules of the Air.  

Next Steps  

The CAA has already conducted an initial review of the regulation of balloon flying in the UK. 

The DB-6R type balloon involved in this tragic accident was an amateur-built balloon and designed 
specifically for competition flying. There are two further DB-6R type balloons recorded on the UK civil 
aircraft register. In October 2023 the CAA issued directions to stop both these aircraft from flying, 
based on the preliminary findings from the AAIB’s investigation into this accident. These directions 
will remain in place until the CAA is satisfied that the unsafe conditions identified in the AAIB’s final 
report have been satisfactorily addressed and the balloons are independently assessed as airworthy. 

1 Aircraft in this category are those that were previously managed by the European Union Aviation Safety Agency (EASA) and were 
considered as EASA types. These are regulated under UK Regulation (EU) 2018/1139 (known as the UK Basic Regulation) and its 
implementing regulations covering airworthiness, operations, flight crew licensing, etc. 
2 Aircraft in this category are managed nationally under the UK Air Navigation Order 2016, as amended.

Following publication of the AAIB’s final report, the Senior Coroner will be aware that two safety 
recommendations were issued to the CAA. The CAA has accepted both recommendations and has 
committed to working with the BBAC to produce guidance in relation to the design, testing and 
inspection of amateur-built balloons (including those used in competition flying). Additionally, the 
CAA will collaborate with the BBAC to produce guidance for the safe oversight of balloon events. The 
AAIB has classified the CAA responses as ‘adequate-open’ and the recommendations will remain 
open until the CAA has delivered on its commitment. The AAIB recommendations and the CAA’s 
initial response are set out below: 

AAIB Recommendation 2024-008  
It is recommended that the Civil Aviation Authority publish 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.  

CAA Response  
The CAA accepts this recommendation and will publish guidance to mitigate the risk of accidents 
caused by unsafe conditions arising from the design, testing, and inspection of amateur-built 
balloons. The CAA will liaise with the British Balloon and Airship Club (BBAC) in producing this 
guidance.  
The CAA will provide an update on the actions taken to address this safety recommendation by the 
end of February 2025.  

AAIB Recommendation 2024-012  
It is recommended that the Civil Aviation Authority publish guidance for the safe oversight of 
competition balloon flying in the UK, to ensure the risks associated with the activity are appropriately 
understood by competitors and managed by competition organisers.  

CAA Response  
The CAA accepts this recommendation and will publish safety guidance for balloon events to ensure 
the risks associated with competition balloon flying are understood by competitors and managed by 
competition organisers. The CAA will liaise with the British Balloon and Airship Club (BBAC) in 
producing this safety guidance.  
The CAA will provide an update on the actions taken to address this safety recommendation by the end 
of February 2025. 

Further to the proposed actions set out above, the CAA will continue its review of the regulation of 
balloon flying in the UK with a particular emphasis on whether there should be regulation of the 
design, construction, inspection and testing of amateur or home-built balloons and of competition 
balloon flying. The CAA will continue to work with domestic aviation stakeholders to mitigate the 
risks to public safety in accordance with the concerns highlighted in the Senior Coroner’s Report.  

This review process will take several months to conclude and involve dedicated subject matter 
experts from the CAA’s General Aviation Unit (balloon airworthiness and operations) working in 
collaboration with the BBAC. The CAA seeks to balance safety with proportionality, taking into 
account analysis of safety data derived from amateur balloon flying in the UK. At the conclusion of 
this process the CAA will consider whether rule changes are required.

INVESTIGATION INTO THE DEATH OF MR PETER RICHARD GREGORY 

CIVIL AVIATION AUTHORITY SUPPLEMENTAL RESPONSE TO A REPORT ON ACTION TO PREVENT 

OTHER DEATHS PURSUANT TO REGULATIONS 28 & 29 OF THE CORONERS (INVESTIGATIONS) 

REGULATIONS 2013 

Introduction 

The UK Civil Aviation Authority (‘CAA’) is providing this supplemental response to HM Senior 
Coroner’s report on action to prevent future deaths dated 2 August 2024 (‘the report’), issued 
following the inquest into the tragic death of Mr Peter Richard Gregory. 

The CAA’s initial regulation 29 response to the report was filed with the coroner’s office on 26 
September 2024. 

Air Accident Investigation Branch Report dated 23 May 2024 

The Senior Coroner will be aware that the UK Air Accident Investigations Branch (‘AAIB’) published a 
final report into the circumstances of this accident on 23 May 2024 which contained two safety 
recommendations for the CAA. The CAA accepted both recommendations and has been working 
with the British Balloon and Airship Club to address the issues identified in the report. A written 
update was recently sent to the AAIB by the CAA, the contents of which are set out below: - 

Safety Recommendation 2024-008 

It  is  recommended  that  the  Civil  Aviation  Authority  publish  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. 

CAA Response to Safety Recommendation 2024-008 

The CAA is currently developing 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.  

The CAA has been liaising with the amateur built balloon community with a view to producing 
guidance in the form of webpages on the CAA website to provide best practice guidance on the 
design, testing and inspecting of amateur built balloons and it is hoped the BBAC will also provide 
guidance in this regard and our liaison with them continues. It is also our intention to issue a Safety 
Notice (SN) regarding our decision to continue to allow the amateur built balloons to be unregulated. 
The SN shall also direct to the CAA website guidance and our previous Safety Directive (SD) on 
volumetric and occupancy limitations which will endure on a non-expiring basis.

The CAA will provide an update on the actions taken to address this Safety Recommendation by the 
end of June 2025. 

Safety Recommendation 2024-012 

It  is  recommended  that  the  Civil  Aviation  Authority  publish  guidance  for  the  safe  oversight  of 
competition balloon flying in the UK, to ensure the risks associated with the activity are appropriately 
understood by competitors and managed by competition organisers. 

CAA Response to Safety Recommendation 2024-012 

The CAA is currently developing safety guidance for balloon events to ensure the risks associated with 
competition balloon flying are understood by competitors and managed by competition organisers. 
This will be in the form of a CAP [Civil Aviation Authority Publication] document.  

The CAA has been liaising with the British Balloon and Airship Club and a working group has been 
established with Ballooning SMEs [Subject Matter Experts] from across the event and competition 
space to produce this CAP with an initial meeting on Thursday 27th February. The working group will 
review current guidance and rules within the UK and Overseas and identify any gaps to produce 
material for the CAP. 

The CAA will provide an update on the actions taken to address this Safety Recommendation by the 
end of June 2025. 

There are approximately 50 amateur-built hot air balloons currently flying in the UK. The CAA’s 
review of available safety data for this aircraft type, and both the AAIB and Senior Coroner’s reports 
will result in the CAA issuing a new Safety Notice (‘SN’) related to aircraft design, construction and 
testing. Furthermore, the CAA will publish new guidance for operators.  

The CAA has determined that the airworthiness of amateur built balloons can remain free of direct 
regulation, but flight safety will be enhanced with the addition of newly published measures for 
better managing design integrity, construction, inspection and testing (and consequent in-service 
performance) that will be promulgated by the CAA in the SN and links to additional guidance 
available on the CAA website. 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 balloons limiting volumetric size of balloon envelope 
and occupancy, in keeping with the intent that these aircraft are for recreational, rather than for 
commercial use.  

The CAA has also recently hosted a meeting with SMEs from the UK ballooning community. During 
this meeting, attendees discussed a further proposal for the CAA to issue new operational safety 
guidance, focussing on acceptable rates of ascent/descent in balloon competition flying, a 
standardised safety/competition briefing, and broader event guidance with the intention that it shall 
be more widely promulgated via a newly published CAA CAP. 

Before the next working group meeting planned for April 2025, the group has been tasked with 
gathering additional safety data relevant to the matters raised by both the AAIB and Senior Coroner. 
In addition, two members of this working group will be attending an international sporting 
conference on competition ballooning during the spring and will report their findings back to the 
working group. The CAA’s new CAP document will be developed over the summer 2025 flying season 
with a view to public consultation towards the end of 2025, prior to publication.

The CAA will complete the work outlined above and publish the SN and operational guidance on or 
before 31st March 2026. This information will be available on the CAA’s website in the publications 
library and will be promulgated to the UK ballooning community using targeted communications.
