Division 21.A.90C Stand-alone changes to the instructions for continued airworthinessF1

Stand-alone changes to the instructions for continued airworthiness (“stand-alone changes”) are changes that are not directly prepared as a result of a change to the type design or repairs design.

Stand-alone changes can only be made by the holder of the design approval for which instructions for continued airworthiness have been established.

Points 21.A.91 to 21.A.109 do not apply to stand-alone changes that:

1. 1.

   do not affect the airworthiness limitations section of the instructions for continued airworthiness, and

2. 2.

   do not require the design approval holder to perform any additional demonstration of compliance with the certification basis.

Stand-alone changes referred to in point (c) must be approved by the design approval holder under procedures agreed with the CAA.
