Fuel Tank Safety (FTS) and CDCCL

Introduction

EASA [Guidance on EASA Fuel Tank Safety Letter]
“Critical Design Configuration Control Limitations (CDCCL): As applied to Fuel Tank safety policy,
this term refers to a feature of the fuel system design the integrity of which must be maintained to
ensure that unsafe conditions do not develop. Features in an aircraft installation or component that
must be retained during modification, change, repair, or scheduled maintenance characterize
CDCCL. These features may exist in the fuel system and its related installation or in systems that
could, if a failure condition were to develop, interact with the fuel system in such a way that an
unsafe condition would develop in the fuel system…”

Who is required to receive Fuel Tank Safety and CDCCL Training?

  • Level 1: Quality and Management Staff (as per ED 2009/006/R and ED 2009/007/R), involved in the maintenance or continuing airworthiness of fuel systems and aircraft impacted by these regulatory requirements.
  • Level 2: Qualified Staff in charge of the continuing airworthiness of aircraft and fuel systems affected by these regulatory requirements (as per ED 2009/006/R and ED 2009/007/R).

What online training do we offer?

Training available in English (contact us if you need training in another language).
