GM1 26.300(c) and 26.330(c) Substantiation of change and repair status

Q: How can an applicant demonstrate that a change or repair will not be incorporated into any other aeroplane under GM1 26.300(c) and 26.330(c)?

The demonstration can be achieved by: (a) providing evidence that there are no available kits for such changes or repairs; or (b) providing evidence that if kits are available, they will not be sold; or (c) ensuring that no future production of such change/repair kits is permitted; or (d) limiting the applicability of the changes and repairs subject to point 26.300(c) of Part-26 by updating the associated instructions for continued airworthiness.

Q: Under GM1 26.300(c) and 26.330(c), can limiting the applicability of changes and repairs be used as a substantiation method?

Yes, limiting the applicability of the changes and repairs subject to point 26.300(c) of Part-26 by updating the associated instructions for continued airworthiness is an acceptable method to demonstrate that the change or repair will not be incorporated into any other aeroplane.

Q: Can updating instructions for continued airworthiness help limit the applicability of changes under point 26.300(c)?

Yes, limiting the applicability of the changes and repairs subject to point 26.300(c) of Part-26 by updating the associated instructions for continued airworthiness is an acceptable method under GM1 26.300(c) and 26.330(c).
