Amended excerpt from Part 145:
145.A.35 Certifying staff and category B1 and B2 support staff
(a) In addition to the appropriate requirements of 145.A.30(g) and (h), the organisation shall ensure that certifying staff
and category B1 and B2 support staff have an adequate understanding of the relevant aircraft and/or components to
be maintained together with the associated organisation procedures. In the case of certifying staff, this must be
accomplished before the issue or re-issue of the certification authorisation.
‘Category B1 and B2 support staff’ means those category B1 and B2 staff in the base maintenance environment who
do not hold necessarily certification privileges. ‘Relevant aircraft and/or components’, means those aircraft or components
specified in the particular certification authorisation. ‘Certification authorisation’ means the authorisation
issued to certifying staff by the organisation and which specifies the fact that they may sign certificates of release to
service within the limitations stated in such authorisation on behalf of the approved organisation.
(b) Excepting those cases listed in 145.A.30(j) the organisation may only issue a certification authorisation to certifying
staff in relation to the basic categories or subcategories and any type rating listed on the aircraft maintenance licence
listed in Part 66, subject to the licence remaining valid throughout the validity period of the authorisation and the
certifying staff remaining in compliance with Part 66.
(c) The organisation shall ensure that all certifying staff and category B1 and B2 support staff are involved in at least six
months of actual relevant aircraft or component maintenance experience in any consecutive two year period. For
the purpose of this paragraph ‘involved in actual relevant aircraft or component maintenance’ means that the person
has worked in an aircraft or component maintenance environment and has either exercised the privileges of the
certification authorisation and/or has actually carried out maintenance on at least some of the aircraft type systems
specified in the particular certification authorisation.
(d) The organisation shall ensure that all certifying staff and category B1 and B2 support staff receive sufficient continuation
training in each two year period to ensure that such staff have up-to-date knowledge of relevant technology,
organisation procedures and human factor issues.
(e) The organisation shall establish a programme for continuation training for certifying staff and category B1 and B2
support staff, including a procedure to ensure compliance with the relevant paragraphs of 145.A.35 as the basis for
issuing certification authorisations under this Part to certifying staff, and a procedure to ensure compliance with Part
66.
(f) Except where any of the unforeseen cases of 145.A.30(j)(5) apply, the organisation shall assess all prospective certifying
staff for their competence, qualification and capability to carry out their intended certifying duties in accordance
with a procedure as specified in the exposition prior to the issue or re-issue of a certification authorisation
under this Part.
(g) When the conditions of paragraphs (a), (b), (d), (f) and, where applicable, paragraph (c) have been fulfilled by the
certifying staff, the organisation shall issue a certification authorisation that clearly specifies the scope and limits of
such authorisation. Continued validity of the certification authorisation is dependent upon continued compliance
with paragraphs (a), (b), (d), and where applicable, paragraph (c).
