Technical Implementation Procedures for Airworthiness and Environmental Certification under The Agreement on Civil Aviation Safety between The Government of Canada & the European Union (Revision 3 - 18 September 2017).
Purpose
The purpose of these Technical Implementation Procedures is to define the interface requirements and activities between Transport Canada Civil Aviation (TCCA) and the European Aviation Safety Agency (EASA) for the import, export, and continued support of civil aeronautical products.
TCCA and EASA shall conduct their certification and validation activities consistent with the Agreement on Civil Aviation Safety (hereafter referred to as the Agreement) and these Technical Implementation Procedures.
The ability to successfully identify and address the root cause is not a given and like many activities benefits from improved knowledge experience and development of individual competence.
Typically it is only by monitoring over time that we are able to confirm that the mitigation's which have been developed as a result of analysed root cause have done the job. However we can draw a conclusion based on our understanding of the analysis and actions which have taken place to assess if we have confidence in the steps which have been taken.
Any shortfall in expectation could for example cause the finding to be re-opened for additional analysis.
Some of the reasons that the true root cause has been miss identified are considered here :
a) Root Cause Analysis (RCA) based on assumptions rather than on objective evidence. It is essential to ensure that all data is accurately classified and clearly understood in relation to the observed facts.
