EASA Reorganises CS-23
The European Aviation Safety Agency has published
Decision 2017/013/R. The objective of this Decision
is to improve the efficiency of the certification process
by reorganising CS-23 "Certification Specifications for
This reorganisation of CS-23 introduces a new
concept. The current EASA CS-23 is replaced by
objective requirements that are design-independent.
These objective requirements, due to their higher level
of abstractness, also are suitable for aeroplanes within
Minimum Equipment Requirements for General
Aviation Operations Under FAR Part 91.
I recently attended a maintenance seminar where
an FAA inspector gave a good presentation on the
use of minimum equipment lists. However, when
I asked the question regarding aircraft without an
MEL, he pointed to the FAA's listing of MMELs as
being valid. Unfortunately, his answer (and parts of
what he presented) were incorrect. What gives?
The following information is from the Federal
Aviation Regulations and FAA Advisory Circular
the scope of the current CS-VLA "Certification
Specification for Very Light Aircraft." Therefore,
CS-23 Amendment 5 also replaces CS-VLA.
This amendment will contain only CSs. The
related acceptable means of compliance will capture
the technical details and, when applicable, provide
differentiated AMC for the variety of aeroplane
designs within the scope of the new CS-23. This AMC
will be annexed to a separate decision. The aim is to
incorporate consensus standards into the AMC, which
will allow for a faster adoption of new technologies
and better up-to-date standards. This improved
flexibility is intended to encourage the introduction of
safety-enhancing features into new designs and reduce
the certification costs for the aeroplanes at stake.
The new CS-23 will become effective in August
