EWIS TG 7 & 8 Initial

The aviation industry is continuously improving when it comes to safety.

As bad as it is, lessons are learned with every incident or accident, big or small. The cause of it is analyzed and procedures are drawn up or changed on the basis of this. One of the results of such an analysis can be that there is a need for training, to create or increase awareness for a certain matter for example. One such training is EWIS.

Following EWIS training is set mandatory by the aviation authorities. If you don’t follow this course, you won’t be allowed to practice your passion: working on the Aircraft.

This initial training is custom made to meet the requirements given by the aviation authorities for Target Group 7 and 8.

Target Group 7: Flight Deck Crew.

Target Group 8: Cabin Crew

The training consist of the following modules:

• Module A: General EWIS Practices.
• Module C: Inspections.
• Module D: Housekeeping.
• Module E: Wire.

Module A: General EWIS Practices

Learning Objectives:

• Know the safety procedures of normal and non-normal maintenance procedures so that the person can protect himself/herself and the aeroplane.

Detailed Topic Overview:

1. Safety Practices
   • Current is lethal – first aid
   • Applying power to the aeroplane
   • Isolating the circuit
   • Aeroplane warnings
   • Human factors

---

Module C: Inspections

Learning Objectives:

• Know the effects of fatigue and complacency during inspection and how to combat these effects (human factors).
• Recognize typical wiring system damage, such as hot gas, fluid contamination, external mechanically induced damage, chafing, corrosion, signs of overheating of wire, wire bundles, connective and control device assemblies.

Detailed Topic Overview:

1. Human factors in inspection
   • Fatigue
   • Complacency
2. Wiring system damage
   • Swarf/FOD/metal shavings
   • External mechanically induced damage
   • Hot gas
   • Fluid contamination
   • Vibration/chafing
   • Corrosion
   • Signs of overheating

Module D: Housekeeping

Learning Objectives:

• Recognize external contamination and other damage due to external environmental conditions.
• Know the aeroplane internal contamination sources so that inspection processes can be effectively carried out and contamination damage easily recognized.

   • Lint/dust
   • Bleed air and hot areas
   • Hazardous materials
3. Other contamination sources
   1. Paint
   2. Corrosion inhibitor
   3. Drill shavings/swarf
   4. Foreign objects (screws, washers, rivets, tools, etc.)
   5. Animal waste
