GM Guidance material

## GM1 21.A.249 Transferability

GENERAL

1\. Transfer of the approval would normally only be agreed in cases where the organisation itself remains substantially unchanged.

2\. An acceptable transfer situation could be for example a change of company name (supported by the appropriate certificate from the National Companies Registration Office or equivalent) but with no changes to site address or senior company manager. However, if the same legal entity were to relocate to new premises with a new senior company manager and/or new departmental heads, then a substantial investigation by EASA would be necessary such that the change would be classified as a re-approval.

3\. In the event of receivership there may be good technical justification for continuation of the approval provided that the company continues to function in a satisfactory manner. It is likely that at a later stage the approval might be surrendered by the receiver or transferred to another legal entity in which case the former paragraphs apply.
