INTERIM REPORT – OPTIONS FOR CHANGE
EASA.2009.OP.21
2 Data sources considered for this study
Questionnaires
As described in the Data Summary and Analysis section of this Report, the Study Team has
attempted, by means of questionnaires, to ascertain the status quo of a broad range of
factors concerning de-icing / anti-icing, and involving the main involved stakeholder groups.
This data was not the only source from which the Study Team developed its options.
EASA
The Recommendations made by the AAIB and BFU, and the options proposed and
dismissed in A-NPA 2007-11 (summarised below) are all in concord with the Terms of
Reference for this Study (2009.OP.21); in that they request the contractor to make
appropriate recommendations as to the most effective ways in which the NAAs of the EASA
Member States could regulate de-icing / anti-icing services in a harmonised way, so that the
safety of aircraft operations is maximised and a level commercial playing field remains
ensured. These recommendations should centre on how the following areas can be
improved at the aerodromes of the EASA Member States:
− availability of type 1 fluids, and
− quality of service provision.
Interviews
During the data collection phase of this project, participants and interviewees were requested
to provide their own recommendations, and these have been summarised and included
below.
AEA
When considering the documents “AEA Recommendations” and “AEA Training Manual”, the
latter offered more general recommendations for improving overall standards, rather than the
more specific technical practices recommended in the former.
Safety
Attachment A to this Study (Summary and Analysis of Available Safety Data) makes some
conclusions regarding the regularly occurring underlying factors that may contribute to
reduced risk, and these have been taken into account when drafting the options for change.
In the absence of adequate quantity and quality of specific human error safety data
concerning de-icing / anti-icing, the sections that follow provide, from valid sources, an
overview of desired options and recommendations, which give a broad overview of the
