Background
On 17 November 2021, F-35B Lightning ZM152 (BK-18) assigned to 617 Squadron Royal Air Force was embarked on HMS Queen Elizabeth. The aircraft was subsequently lost. The exact circumstances were not detailed in the initial convening documentation.
Inquiry Establishment
In accordance with Section 343 of the Armed Forces Act 2006 and Joint Service Publication 832, the Director General of the Defence Safety Authority (DG DSA) convened a Service Inquiry (SI) on 2 December 2021 to investigate the loss. The inquiry panel assembled at MOD Boscombe Down for administrative briefing and was formally convened by the DG DSA at 1500 hours that day.
The SI panel comprised a President, two Members, a Legal Advisor, and technical investigation support provided by the Defence Accident Investigation Branch (DAIB). A mentor from DAIB was also assigned. The panel underwent induction training at the DAIB facility immediately after convening and subsequently established working accommodation.
Terms of Reference
The terms of reference required the SI to investigate and report on the facts related to the loss, recording all evidence and expressing opinions as directed. The inquiry was to make recommendations to prevent recurrence. An initial report on the investigation's commencement was due by 24 January 2022.
Observations
The convening order noted that attendance at the SI was limited to DAIB personnel, human factors specialists, and other specified advisors. The costs of the inquiry were to be borne by the DG DSA. The inquiry continued with a change in panel presidency in January 2022, as documented in the record of changes.
