What was the main reason to introduce SFAR 88?
Eliminate Ignition Sources On May 7, 2001 the FAA issued a far-reaching safety rule called ‘SFAR 88’ to minimize ignition sources in fuel tanks. SFAR 88 changed the way airplanes are designed, operated and maintained.
What is the main concern of the SFAR 88?
SFAR 88 mandated a review of fuel tank system service history to reveal ignition sources in airplane fuel tanks due to unforeseen failure modes or factors not considered at the time of original certification of the airplane.

When was sfar88 issued?
Note: SFAR 88 amendment issued Sept. 10, 2002 allows equivalent safety provisions for fuel tank system fault tolerance evaluations.
What is the purpose of the flammability reduction system?
Designed to protect both military and civil aircraft from risk of fuel vapour ignition. Traditional systems such as Fuel Tank Inerting (FTI) rely on the removal of oxygen to prevent ignition by lighting strike or gunfire.
In which year did SFAR 88 come into effect?
2002
Note: SFAR 88 amendment issued Sept. 10, 2002 allows equivalent safety provisions for fuel tank system fault tolerance evaluations.
Which aircraft types does SFAR 88 apply to?

Why was EWIS introduced?
An electrical wiring interconnect system (EWIS) is the wiring system and components (such as bundle clamps, wire splices, etc.) The change from EIS to EWIS was done to emphasize the focus on the actual wires and wiring of the systems throughout aircraft.
What are the 5 EWIS degradation factors?
Chemical contamination – Chemicals such as hydraulic fluid, battery electrolytes, fuel, corrosion inhibiting compounds, waste system chemicals, cleaning agents, deicing fluids, paint, and soft drinks can contribute to degradation of EWIS.
