A maintenance organisation can only fabricate small parts for a particular project i.e not produce stock parts.
A Factory can be the like of BAES or Airbus that have to demonstrate how they have control of the suppliers, materiel and processes to produce a constant result.
If they can produce a standard part they can be awarded the right to issue a Form 1. If they can produce an aircraft, they can be awarded for a Form 52. It can take 5-10 years for a Form 52.
If it remains a kit, then AMO is sufficient. Its good to have anyways, not mandatory.
