Preparing your team for work inside aircraft fuel tanks

Fire Safe International’s aircraft fuel tank entry training course takes your maintenance team through a complete planned fuel tank entry, from releasing the tank for access to handing it back for inspection and close-up.

Aircraft fuel tank work demands that your technicians carry out controlled maintenance through small access panels in a poorly ventilated and often heavily obstructed space. Residual fuel and cleaning products may produce a flammable or harmful atmosphere, and jet-fuel headspaces can remain potentially flammable below the fuel’s normal flash point, so ventilation, gas monitoring, static control and the exclusion of ignition sources must continue throughout the entry in accordance with the risk assessment, aircraft maintenance data and site procedures.

Using a purpose-built aircraft fuel tank entry training rig that simulates the conditions and access requirements present in a live entry, the course lets your team rehearse how the tank is prepared, entered, monitored and evacuated as part of a tightly controlled aircraft maintenance task – improving safety and process efficiency under demanding and dangerous conditions.

The unit reproduces vertical, horizontal and underside access, including the restricted body positions and equipment-handling demands created by entry from below. Every exercise is therefore grounded in the physical realities your technicians face around aircraft tanks.

Please note: The course prepares technicians to enter and work inside a tank safely, but it does not authorise them to isolate aircraft systems, carry out maintenance or sign the aircraft back into service under Part-145. These responsibilities remain with the nominated person approved under your maintenance organisation’s procedures.

How our training service helps your aircraft fuel tank entry team

  • Less disruption to scheduled maintenance

    Trained technicians will understand how tank layout, access-panel position, ventilation, hose routing and nearby work affect the entry, reducing avoidable stops once the aircraft is opened for maintenance. 

  • Safer movement through restricted tank spaces

    Your team will be better prepared to work through narrow openings and around ribs, baffles and internal structures while keeping their tools, monitoring lines and breathing-air hoses under control. The techniques used during live work must still follow the aircraft maintenance data, risk assessment and approved entry procedure for the specific aircraft and task.

  • Stronger control of ignition and contamination risks

    Training can help personnel understand the importance of adequate and correct controls applied to lighting, radios, tools, clothing, footwear and consumables that pose an ignition or contamination risk – helping protect the aircraft, fuel system and workforce throughout the task.

  • A faster, more orderly withdrawal when conditions change

    Training prepares your entry team for the unusual, so that entrants and support staff can understand and respond promptly to gas alarms, ventilation problems, communication loss or an emergency inside the tank, without improvising around a difficult exit route.

Who benefits from this training? 

Our customers include a variety of stakeholders in the aviation sector, including maintenance contractors, airlines, manufacturers, and defence organisations. With a versatile course structure that can be adapted to your operational priorities and training requirements, several classes of employees could benefit from the training:

Commercial and defence aircraft technicians who enter wing, centre or fuselage tanks 
Your standby staff, gas testers and entry controllers
Maintenance supervisors and permit issuers who confirm that the aircraft and tank are ready for entry
Employees involved in emergency withdrawal or casualty recovery

Why choose us?

With over 20 years’ experience in aviation training and a specialist fuel tank training unit, Fire Safe International is the ideal training partner for both commercial and defence maintenance teams. Our instructors understand how aircraft fuel tank entry sits within a wider maintenance operation, with separate responsibilities for permits, engineering authority, tool control and hand-back. They can work credibly with experienced aviation engineering and maintenance teams, using the terminology and procedures already established on site.

Make an enquiry

Does the course cover entry through access panels beneath the wing?

Yes. Our purpose-built training unit allows your team to practice entry from below, where gravity changes body position, equipment handling and casualty recovery. Scenario-based exercises can address restricted openings, movement through internal structures, communication with the entry controller and the practical challenges of extracting an incapacitated technician through a lower access panel.

Can ordinary lights, tools and communications equipment be used inside the tank?

Any equipment taken into the tank must match the hazardous-area assessment and your aircraft maintenance procedures. For instance, some entries require Ex-rated or intrinsically safe lamps and radios, bonded ventilation ducting, antistatic clothing and footwear, and task-approved tools. Equipment that has not been authorised for the entry should remain outside the tank. Tool, component and consumable control should follow your organisation’s approved maintenance and accountability procedures.

Does one course cover every aircraft type?

No single course can reproduce every aircraft type, tank layout or maintenance procedure. Our core training covers the principles and practical controls associated with aircraft fuel tank entry, while the course can be adapted around representative access arrangements, your equipment and the aircraft-specific procedures relevant to your organisation.

Does the course qualify individuals to test the atmosphere or issue the entry permit?

The course can train delegates to sample the tank atmosphere correctly, operate the specified gas detector, interpret the information it provides and respond to oxygen, flammable-vapour or toxic-gas alarms. Completing the course does not automatically authorise a delegate to test the atmosphere or issue an entry permit. These responsibilities must be assigned by the employer to personnel who have the required competence and authorisation under the organisation’s permit-to-work and maintenance procedures.
