If something is not defined in the FARs, then it is a kind of a grey area and different FSDOs will give you different answers.

The definitive answer can come only from the FAA Chief Counsel, and a website with those rulings is here.

There is a whole load of obscure stuff which is not defined in the FARs, especially involving obscure aspects of training and flight experience outside the USA.

The bottom line in practice is that if the DPE accepts something, does the checkride, and signs your certificate, then you are done and you move forward from there.

You need to speak to the actual DPE who you will be working with and check this with him.

Thank SoCal App,

That was ATP 121

IO 540,

Thank you so much for your suggestion, I have emailed the Chief Counsel and just waiting for the reply. Just wondering what was the reason behind of this part 61. b.1 (i) and (ii). If this regulation was made with assumption that the pilot keep applying the content of the 121, or 125 or 135 regulation in the working environment so his ATP knowledge will always current, so it means no matter which company's location as long as applying the part 121, or 125 or 135 as per FAA part respected the pilot can continue through Practical Test even with expired knowledge test report.
Once again thank for the suggestion and sharing.
