Preparation for Entry Into the Fuel Tank

It is most important to ensure that all persons who are engaged in the process of Fuel Tank Entry are fully trained on all aspects of the following information to ensure that all precautions are taken and all risks minimised.

Steps which must be taken include the following:

a) Ensure the aircraft is electrically grounded

b) Ensure that Fire Extinguishers are available (typically CO2 would be used for a Fuel Fire

c) Deactivate all Electrical Systems on the Aircraft and suitable placard

d) Defuel the aircraft using the Aircraft Maintenance Manual Procedures

e) Deliver a safe atmosphere for maintenance personnel by ensuring the following:

In aviation we have procedures for just about every activity. As we understand procedures are connected to policies as well as the need to demonstrate regulatory compliance.
 
Procedures belong within the QC environment but facilitate the functioning of the QA process. Without procedures auditing becomes very challenging (Ultimately it is the business area owner or post holder/nominated person (NP) who has the ultimate responsibility for the integrity of the procedure).

In our PART M - CAR M / Part 145 – CAR 145 environment we have the Continuous Airworthiness Management Exposition (CAME) and the Maintenance Organization Exposition (MOE) Procedures as well as a myriad of other documents.

What is the difference between Policy, Process and Procedures?
 
A Policy is essentially a set of basic principles and associated guidelines, formulated and enforced by the organization typically designed to demonstrate compliance with a regulatory obligation and in so doing demonstrate objectives and actions in pursuit of long-term goals.
 
A Process is typically understood to be a sequence of usually separate but linked procedures and which, also requires a number of resources to achieve.
 
Procedures provide instructions or guidance ideally in clear, non-ambiguous, and effective manner describing in “simple language” to how a particular task or activity should be accomplished.

Whilst many organisations have procedures related to Fuel Tank Safety processes, there are considerably less in respect of processes and practices related to Electrical Wiring Interconnect Systems.

What Procedures should we consider?

a) Procedures in respect of Tripped Circuit Breakers and how we will manage the associated trouble shooting activities. To ensure that Flight Crew never reset circuit breakers (or reset circuit breakers) unless the procedure is a direct “in flight” instruction driven by documentation available on board the aircraft for example as an OPS Manual procedure.

To also ensure that ground support personnel carry out trouble shooting before proceeding to reset a circuit breaker as simply resetting without additional maintenance activity may be a pre-cursor to a more serious problem and even subsequently a fire.
