EWIS Recurrent for Groups 1 & 2 – 1 Day


The origins of the requirement for EWIS Training go back to a number of incidents which have had a catastrophic effect on the industry with instances of in-flight smoke and fire events in which contaminants were ignited by electrical faults which allowed a fire to be sustained and spread. Considerable research was conducted by The FAA and the National Transportation Safety Board (NTSB) together with the European Stake holders. The outcomes were conclusive and determined the specific need for EWIS Training. Electrical Wiring Interconnect System EWIS Training was issued as an EASA requirement in the summer of 2008. There is much confusion across industry as to the requirements to comply with the need for training EWIS within the Part 145 and Part M environment. AMC 20-22 makes It very clear as to the requirements which are to be complied with to ensure the organisation remains in conformity with EASA regulatory requirements. Ultimately in accordance with the terms of the approval issued to Operators and MRO’s It is the Operators and Maintenance Organisation Responsibility to comply with the requirements of Electrical Wiring Interconnect Systems working practices and procedures including specifically EWIS training.

Sofema Aviation Services is pleased to offer a 1 Day in company Training to allow you to manage and deliver your own EWIS training to ensure compliance with the requirements of AMC 20-22.
