 Where the user/installer performs work in accordance with regulations of an airworthiness authority different than the airworthiness authority specified in block 1, it is essential
 that the user/installer ensures that his/her airworthiness authority accepts items from the airworthiness authority specified in block 1.
 Statements in blocks 13a and 14a do not constitute installation certification. In all cases aircraft maintenance records must contain an installation certification issued in
 accordance with the national regulations by the user/installer before the aircraft may be flown.
