GM 145.A.61 Management System – additional occurrence reporting procedures
CAA ORS9 Decision No. 38
MANDATORY REPORTING — GENERAL
(a) For organisations having their principal place of business in the UK, Regulation (EU) 2015/1018 lays down a list classifying occurrences in civil aviation to be mandatorily reported.
This list should not be understood as being an exhaustive collection of all issues that may pose a significant risk to aviation safety and therefore reporting should not be limited to items listed in that Regulation.
(b) AMC-20 ‘General Acceptable Means of Compliance for Airworthiness of Products, Parts and Appliances’ provides further details on occurrence reporting (AMC 20-8A).
