Issues and observations made by Steve Bentley MD SAS (

EASA Clearly identifies roles and responsibilities of the Role of EASA Part 147 Practical Trainer and Practical Assessor. However EASA has omitted to clearly identify the Role of EASA Part 145 Trainer “Supervisor / LAE”

Following the amendment of EC 1149/2011 EASA Part 145 has NOT been updated to include either AMC or Guidance material required to ensure standardisation of the OJT / OJE Process – rather it is left as an open obligation of each organisation to individually develop a procedure which is then accepted by the local Competent Authority (CA) (potential weakness and exposure).

Appendix III to AMC defines On-the-job-Experience as requiring a particular skill set to be present with the role of Supervisor related to the role of OJT “trainer” – this requires both training to an organisational standard & authorisation (see highlighted area above).

Sofema Aviation Services looks at several Organisational Challenges related to the Management of  on the Job Training within an EASA Part 145 Environment

Regulatory Background

Driven by changes in EASA regulations in accordance with EC 1149/2011 EASA introduced unique terms for Practical Training which is the responsibility of the 147 Organisation and “On the Job Training (OJT) which typically sits with the 145 organisation.

Note 2 – Whilst EASA Part 147 Contains multiple references to roles and responsibilities in respect of the role of Practical Assessor and Practical Trainer – There is an absence of guidance within EASA Part 145 - Clearly this is a challenge.

EASA References within Part 66 provide for very limited guidance material related to 145 – Ref appendices to Annex III 

Appendix III - 4.2 Point 6 On the Job Training (OJT) shall be approved by the competent authority who has issued the licence.
