1. Issuance of an EASA Form 1 for components removed serviceable from EU registered A/C
Regarding the removal of serviceable components from a Member State registered aircraft, paragraph 2.6.1 of AMC 145.A.50 (a) applies. The intention of this paragraph is that a Part 145 organisation may issue a Form 1 for those components only if compliance with paragraph 2.6.1 (a) to 2.6.1 (i) can be demonstrated. The organisation must define the procedure in its Maintenance Organisation Exposition.
2. Swap/change over of serviceable components between EU registered A/C
When an organisation maintains a component for use by the organisation, an EASA Form 1 shall be issued. However an internal release certificate (serviceable tag) may be accepted depending upon the organisations’ internal release procedures defined in the Maintenance Organisation Exposition and the contractual arrangements with the operator (see AMC 145.A.50 (a), paragraph 1.2).
Such release procedure addressed in the MOE must meet paragraph 2.6.1 of AMC 145.A.50 (a) requirements, whatever the organisation wants to issue: a Form 1 or a serviceable tag.
3. Issuance of an EASA FORM 1 for components removed serviceable from a non EU registered A/C
Regarding the removal of serviceable components from a non Member State registered aircraft, paragraph 2.6.2 of AMC 145.A.50 (a) applies. The intention of this paragraph is that a Part 145 organisation may only issue a Form 1 for such components when this organisation has leased or loaned the component and retains the airworthiness control of the
component.
When issuing an EASA Form 1 for such a component, the organisation shall also comply with paragraphs 2.6.1 (a) to 2.6.1 (1) of the AMC.145.A.50 (a). The organisation must define the procedure in its Maintenance Organisation Exposition.
4. Swap/change over of serviceable components between non EU registered A/C
When an organisation maintains a component for use by the organisation, an EASA Form 1 shall be issued. However an internal release certificate (serviceable tag) may be accepted depending upon the organisations’ internal release procedures defined in the Maintenance Organisation Exposition and the contractual arrangements with the operator (see AMC
145.A.50 (a), paragraph 1.2).
Such release procedure addressed in the MOE must be based on the same condition as the issuance of the EASA Form 1 for components removed from non EU registered aircraft. That is to say compliance with paragraphs 2.6.2 and 2.6.1 (a) to 2.6.1 (1) of the AMC 145.A.50 (a), whatever the organisation wants to issue: a Form 1 or a serviceable tag.
5. Is it possible for a Part-145 approved organisation to issue an ‘EASA Form 1’ for a component removed ‘serviceable’ from a UK registered aircraft after December 31, 2020?
Yes, it is possible provided that such a component was removed under a procedure concerning issuance of an ‘EASA Form-1’ for components removed ‘serviceable’ from a non-EU registered aircraft which is approved in the MOE of the organisation conducting the removal. This procedure is described in §2.8 of AMC2 145.A.50(d). When the Part-145 maintenance organisation has the capability to control the airworthiness status of such component then §2.6.2 of AMC2 145.A.50(d) is applicable.
