FTS / Combined Fuel Tank Safety / EWIS – Refresher

Historical introduction

The legacy page describes knowledge consolidation of both rulemakings, FTS and EWIS, and relevant standard practices, referencing EASA Decisions 2009/006R, 2009/007R and 2009/008R and the General Acceptable Means of Compliance for Airworthiness of Products, Parts and Appliances (AMC-20-21 and AMC-20-22).

Historical objectives

The legacy page describes a one-day course focused on reviewing the concepts of Fuel Tank Safety and Electrical Wiring Interconnection System issues.

It states that the course was intended to review background and elements requiring consideration in relation to fuel-tank safety systems and EWIS.

The stated objective included developing or updating participants' knowledge and practical understanding of Fuel Tank Safety System issues, including ignition sources and ignition prevention.

The course also described an update on development and implementation of flammability-reduction requirements and the nitrogen-generating system.
