Does continuing airworthiness require a Type Certificate Holder (TCH) to ensure manufacturing spare parts indefinitely?
Does continuing airworthiness require a Type Certificate Holder (TCH) to ensure manufacturing spare parts indefinitely?
Answer
No. Continuing airworthiness obligations (as per EASA Part 21) do not necessarily imply an obligation for the TCH to sustain production of spare parts indefinitely. In many cases, the product may have been out of production for decades, and maintaining the industrial capability to manufacture certain parts may no longer be economically or technically sustainable.
