... no limitations other than those included on the licence being used.
This requirement mentioned by Whopity is prescribed in
14 CFR 61.75(e)(3) which states that the certificate holder (bold added):
14 CFR 61.75(e)(3) Is subject to the limitations and restrictions on the person's U.S. certificate and foreign pilot license when exercising the privileges of that U.S. pilot certificate in an aircraft of U.S. registry operating within or outside the United States[.]
It's worth mentioning that this regulation is commonly believed to mean that a US airman certificate issued under 61.75 is subject to the flight crew licensing rules governing the non-US licence, e.g. Part-FCL. The
August 2008 AAIB Bulletin at p 80, reporting on a nosewheel collapse on a Nomad whose captain held a US airman certificate issued under 61.75, cites the above FAR in support of this misconception. The FAA Office of the Chief Counsel provided a legal interpretation on the point in March 2012 to Andrew Krausz at Clyde & Co. Addressing the bulletin FAA states:
The AAIB draws the conclusion from this provision that any and all limitations and and restrictions that a pilot would be subject to under his foreign pilot certificate are incorporated in his US certificate, and apply equally under his US certificate. This conclusion is mistaken.
The interpretation goes on to state:
... the pilot is subject to the restrictions and limitations that appear on the face of the US certificate or foreign pilot license. This language does not include the entirety of regulatory requirements of the foreign State since the holder of the §61.75 certificate is bound by the US regulatory requirements to exercise the privileges of the US certificate. The FAA views that language as addressing the limitations of the sort FAA uses, e.g., "not valid for night operation," where the individual has not completed the night training requirements.
