FAA AMT Airframe Test 2026 – 400 Free Practice Questions to Pass the Exam

Integral fuel tanks are fuel tanks that are formed as a part of the aircraft structure and cannot be removed. This is different from external tanks, which can be attached to the aircraft but are not a part of its structure. While some special materials may be used in constructing integral fuel tanks, the tanks themselves are not made from a special composite material as suggested in option A. Similarly, option D is incorrect as integral fuel tanks are not located inside the aircraft cabin for easy access, rather they are a part of the aircraft's structure.
