Course overview

HF, FTS and EWIS online continuation training courses present part of mandatory aviation training, applicable for all maintenance engineers, technicians and mechanics in maintenance organizations (Part-145 AMO) and also for technical staff in Continuing Airworthiness Management Organizations (Part-M CAMO). 


They assure validity of certification authorization and compliance with regulations for the next two years. They include – by regulation required – content of basics Human Factors, Fuel Tank Safety and Electrical Wiring Interconnecting Systems topics.


Training Type

On-line Human Factor (HF), Fuel Tank Safety (FTS) and Electrical Wiring Interconnection Systems (EWIS) Continuation training – Video presentation with voice over recordings. Duration of all three training is 8,5 hours.


Compliance of the course

The content of Human Factors (HF) continuation training is in compliance with Part-145 AMC2 145.A.30(e) and GM1 145.A.30(e).

The content of Fuel Tank Safety (FTS) continuation training is in compliance with Appendix IV to AMC 145.A.30(e) and 145.B.10(3) and Appendix XII to AMC M.A.706(f) and AMC1 M.B.102(c)

The content of Electrical Wiring Interconnection Systems (EWIS) course is in compliance with AMC 20-22, EASA (ED 2008/007/R of 29/08/2008) training program.


The aim of content

The term “Human factors” (HF) refers to the principles which apply to aeronautical design, certification, training, operations and maintenance whilst seeking to ensure a safe interface between a human and other system components by paying due consideration to human performances. 

The term “Fuel Tanks Safety” (FTS) refers to the principles which apply to aeronautical design, certification, training, operations and maintenance while working on structure and fuel tank safety related components on the aircraft, which may in any way jeopardize safety of aircraft and passengers.

The term “Electrical Wiring Interconnection Systems(EWIS) refers to the principles which apply to aeronautical design, certification, training, operations and maintenance whilst seeking to ensure safe activities in engineering, maintenance, documentation and to expose possible problems of wiring interconnection systems on new and old aircraft types.

In order to reduce the impact of HF, FTS and EWIS, it is highly important to ensure that all the processes involved in the maintenance of aeronautical products are analyzed and any procedural requirements are adhered to at all times. Many investigations of accidents/incidents in aviation have revealed HF, FTS and EWIS to be an important elements in the chain of unfortunate events.


The objectives of the HF continuation course

  • Improve the level of awareness as concerns Human Factors
  • Enhance the understanding of Human Performance issues related to aircraft maintenance activities.
  • Understand the nature of Human Error;
  • Identify and predict potential maintenance Human Error;
  • Reduce human error working under the stress and fatigue;
  • Identify strategies for reducing or controlling maintenance Human Error;
  • Adopt a credible, non-punitive policy toward human error (not violations);
  • Demonstrate a commitment to taking action to reduce error-inducing conditions;
  • Identify threats and deal with them before they become errors;
  • Assist in assessing current and proposed maintenance policies and procedures
  • Develop effective risk management practices.


The objectives of the FTS continuation course

  • Theoretical background behind the risk of FTS including CDCCL

  • Concepts for introducing FTS
  • Instructions for continuing airworthiness (INTRODUCTION, EXAMPLE OF BOEING AIRWORTHINESS, LIMITATIONS)
  • FTS during maintenance
  • Recording of maintenance actions for FTS

The objectives of the EWIS continuation course

  • Familiarisation with the elements of EWIS
  • Overview of the history and background and recognise the elements requiring consideration in relation to EWIS
  • Overview of the EASA and FAA regulatory requirements
  • Overview of EASA AMC guidance material AMC 20-21, -22 & -23
  • Overview of the impact of EWIS on the Part M/G continuing airworthiness management, Part-145 maintenance  and components intended to be fitted thereto.
  • General overview of EWIS damages and aging
  • General electrical wiring interconnection system practices
  • Wiring practice documents such as ESWPMStandard practice for electrical installation using EWIS standards
