An occurrence is an unexpected event, fortuitous or otherwise arising during spaceflight activities or in the preparation for those activities. It is also an incident that, if not corrected or addressed, could or has resulted in an incident or major accident.
The sole objective of an occurrence report is to prevent an accident, without the apportionment of blame or liability.
Occurrence reporting is a mandatory requirement under the Space Industry Regulations 2021 and may additionally be required under the Outer Space Act 1986 or Article 96 of the Air Navigation Order 2016.
Occurrence reports are treated confidentially, to maintain full and free reporting from the space industry or rocket community and to protect the identity of individuals.
