2.By way of derogation from paragraph 1, an organisation whose principal place of business is in a non-member State may demonstrate its capability by holding a certificate issued by that State for the product, part and appliance for which it applies, provided:
(a)that State is the State of design; and
(b)the Agency has determined that the system of that State includes the same independent level of checking of compliance as provided by this Regulation, either through an equivalent system of approvals of organisations or through direct involvement of the competent authority of that State.
3.Design organisation approvals issued or recognised by a Member State in accordance with the JAA requirements and procedures and valid before 28 September 2003 shall be deemed to comply with this Regulation. In such case, the period for closure of level two findings, referred to in Subpart J of Part 21, shall not exceed one year when those findings are associated with differences with previous applicable JAR.
