Comment by Steve Bentley – CEO of Sofema Aviation Services (SAS) – Your Aviation Regulatory Training Provider


We are asked this question with regularity (unfortunately) – Is Sofema Aviation Services / SofemaOnline Approved by EASA to Deliver Regulatory Training?

Why unfortunately? – Because often the person asking is a Compliance or Safety Manager or even a Nominated Post Holder operating within the European Union and working for an Operator, or AMO / CAMO or an Airport or an Approved Training Organisation (ATO) or Maintenance Training Organisation (MTO).

Offering Regulatory Compliant Training for FAA Repair Stations In Classroom & Online

Concerning FAA -EASA Bilateral Agreement

The FAA notes that some part 145 repair stations have European Aviation Safety Agency (EASA) certifications. EASA part 145 contains licensing and training requirements for Approved Maintenance Organizations (AMO) that perform maintenance on articles of those operators under the regulatory control of European Union (EU) Member States.

These EASA part 145 requirements can affect FAA part 145-approved repair stations that also have EASA approvals; since EASA requires maintenance human factors training as part of the Bilateral Aviation Safety Agreement (BASA) and Maintenance Implementation Procedures (MIP) with the United States.

The FAA training program may include the requirements of other civil aviation authorities as long as the part 145 requirements are also met.
