When do I need a dual release on FAA Form 8130-3 under EU/US bilateral agreement?
Under the terms of the EU/US bilateral agreement (BASA) (see here), a DUAL release is required for acceptance of USED engine/components from an US based repair station.
NOTE: a single EASA release on Form 8130-3 with only “Other regulation specified in block 12” ticked in block 14a is also acceptable for USED engine/components. This is to cover the case where component maintenance includes the installation of a used (sub)component released on an EASA Form 1 with ‘single release’ only, and therefore where the assembly is not eligible for US-registered aircraft.
CAUTION: DUAL release is not acceptable for ‘rebuilt’ engine/components because EASA recognises the term ‘rebuilt’ only as a manufacturing/production release (not a maintenance release) and only for engine.
