B. Exceptional Instances. For example, the differences from a B757 to a B767 were determined to be negligible, and an airman qualified in a B767 subsequently received a B757 type rating without further demonstration. C. Credit For Previous Qualification. When credit is permitted, the applicant meets the certification requirements by combining credit for items previously completed in the aircraft in which the airman is qualified, and the additional items accomplished for the new variant or related type. The FAA determines if credit is permitted and how that credit applies to airman certification for each specific aircraft type, variant, or related type through the associated FSB report.
Reports are available for the majority of aircraft that are used in air carrier operations.
The reports may be made available to interested operators, check airmen, and APD's. D. Credit Applicability. The applicant may be credited for other items by previous qualification in the base aircraft. A. Differences Credit. To obtain differences credit permitted by the FSB during airman certification, an airman must be trained and checked in accordance with a program specifically approved for a particular FAR Part 121 operator or training center.
