Is it possible to maintain a component without issuing a Form 1 when it is going to be used by the same organisation?

RESPUESTA DE EASA

The following aspects to be taken in consideration:

• it is possible to release component maintenance on an internal release document (IRD) when this component will be installed on an aircraft by the same maintenance organisation (145.A.50(d));
• The CAMO/operator of the aircraft should be in agreement; and 
• all the information normally required for an EASA Form 1 should be adequately detailed in the IRD (and in MOE procedure). In this case the IRD is considered to be equivalent to an EASA Form 1 for 145.A.42 purpose
