Fatigue Risk Management Systems
NPA 2004-058 was raised in 2004, to propose that
AMOs adopt a fatigue risk management system. This
NPA was subsequently withdrawn by TCCA in 2005,
following CARAC meetings.
Notwithstanding this action, the AEA has reiterated to TCCA its opinion that fatigue risk management
is already covered by the existing human factors
training requirements and the applicable federal and
provincial labor laws. Therefore, the AEA does not
support the regulation of FRMS into AMOs.
News & Regulatory Updates
European Aviation Safety Agency
Recently, EASA issued amendments to both the
maintenance annex guidance and the technical
implementation procedure to the bilateral agreement
(BASA) between the U.S. and Europe. Unfortunately, EASA did not create a separate document
describing the changes to the affected organization.
AEA members potentially affected should, therefore, carefully read the related documents in regards
to the implications on continued airworthiness or the
TIP in regards to initial airworthiness topics (production, design, type certification, ETSO, etc.).
MAG Change 2 contains the following changes:
• Changes to the definition and acceptable data
of design changes and design repair data.
• Standard parts definition.
• Dual release statement on Form 1.
TIP Revision 2 contains the following changes:
• Application package for a European STC
holder for a U.S. STC (STC validation).
• Acceptance of repair design data.
• Transfer of type certificates and supplement
• Additional requirements for imported product.
New NPAs have been issued by EASA. Notewor18
thy is NPA 2012-19 in regards to air-ground datalink
and ADS-B. The NPA proposes a cancellation of two
AMCs in regards to Mode S transponder systems
(AMC20-13) and ADS-B NRA (AMC20-24), and,
instead, proposes a new certification specification
applicable to the installation of airborne communications, navigation and surveillance systems containing
two books. The proposed Book 1 would cover the
airworthiness and interoperability standards, and Book
2 would provide the relevant guidance material.
An important statement in the NPA is that current
JAA TGL 13- and AMC 20-13-compliant installations
would be considered not compliant to the commission
regulation EC 1207/2011 (performance and interoperability of surveillance for the single European sky).
The continued effort of EASA to harmonize the
ETSOs issued with FAA TSOs required the agency
to issue another NPA 2012-16. The NPA proposes
changes to the ETSO list containing the deletion of
some ETSOs, which became obsolete as well as the
amendment of current ETSOs and the introduction of
Proposed ETSOs to be deleted contain:
• ETSO C9c – automatic pilot.
• ETSO C52b – flight director.
• ETSO C60b – addressing the stop of
worldwide Loran-C services.
• ETSO C74d – airborne ATC transponder
• ETSO 2C87 – radio altimeter.
• ETSO 2C91a – ELT.
New ETSOs may contain:
• ETSO C160a – TSO C160a in regards to
VDL Mode 2 Communication equipment.
• ETSO C164 – night vision goggles.
• ETSO C178 – arc fault circuit breakers.
• ETSO C198 – automatic flight guidance
and control system equipment.
• ETSO C200 – underwater locating device.
AEA members involved in the design, production
or installation of such equipment are required to
read and comment on the related NPAs.
For those involved in design of changes to
products, the following recently released agency
decisions should be of interest:
• CS 29 amendment 3.
• CS 27 amendment 3.
