Fuel Tank System Safety JAA MAINTENANCE SECTORIAL TEAM Len Arnot-Perrett Joint Aviation Authorities, United Kingdom Section Leader, Maintenance Requirements & Policy Section

Fuel Tank Safety Implementation: 

Fuel Tank Safety Implementation JAA fuel tank system safety policy set out in JAA policy letter INT/POL/25/12 INT/POL/25/12 harmonised with FAA SFAR 88 JAA/FAA policy for implementation of corrective actions to address unsafe conditions and non compliant items: harmonised principles

Fuel Tank Safety Implementation: 

Fuel Tank Safety Implementation Implementation of corrective actions guidance material drafted Guidance material comprehensive – addresses TC/STC holders as well as operators and maintenance organisations JAA temporary guidance leaflet to be drafted and harmonised with FAA/JAA jointly developed FAA draft Harmonised implementation will facilitate transfer of aircraft between States

Fuel Tank Safety Implementation: 

Fuel Tank Safety Implementation Corrective actions required to address unsafe conditions will be AD Corrective actions identified to address non-compliance will be dealt with through existing processes Possible revisions to Maintenance Manuals – aircraft/component (MM/CMM) Wiring Practices Maintenance Procedures Fault Isolation Manuals MRB report MPD

Fuel Tank Safety Implementation: 

Operator responsible for in-service compliance Scheduled/un-scheduled maintenance Modification Operation Component Maintenance JAR 145.35 continuation training programme will need to address fuel tank safety topics Fuel Tank Safety Implementation

Fuel Tank Safety Implementation: 

Fuel Tank Safety Implementation In-service aircraft fleet survey provides indications that inspection standards and maintenance standards do not address fuel tank safety issues Loose articles in tanks Lack of preparation for inspection Lack of awareness Maintenance induced damage Survey of one representative fleet showed that 16% of mandatory occurrence reports for ATA 28/73 had maintenance error contributing factors

Fuel Tank Safety Implementation: 

Fuel Tank Safety Implementation Corrective actions will require additional maintenance and modification Fuel tank system intrusions should be kept to a minimum consistent with maintaining certification standard Future design should take into account, issues associated with maintainability

Fuel Tank Safety Implementation: 

JAA policy will require each JAA member state intervention – prior to EASA each State will need to raise AD for corrective actions Harmonisation of implementation time frames will require co-ordination Fuel Tank Safety Implementation
