Description

Airbus A318 A319 A320 A321 Aircraft Maintenance Manual Chapter 28 Fuel Rev 40 – 2012

The Airbus A318 A319 A320 A321 Aircraft Maintenance Manual Chapter 28 Fuel Rev 40 – 2012 is a dedicated Chapter 28 reference for the fuel systems used across the A318, A319, A320 and A321 aircraft families. Its coverage goes well beyond a basic system overview: the manual brings together fuel-system description and operation, servicing, maintenance practices, deactivation and reactivation, adjustment and test, inspection and check, cleaning, repair, and component removal and installation tasks. The material is organized by ATA-style section and component reference, making it useful when the work involves tanks, pumps, valves, venting, transfer, refuel/defuel, quantity indication or fuel level sensing.

Across its 2149 pages, this Airbus Chapter 28 Fuel maintenance manual provides detailed task references and illustrated figures for the wing and center tank fuel system, cockpit and refuel controls, electrical supplies and interfaces, tank access and bonding, fuel distribution and pumping, and the sensing and indication equipment used to monitor fuel quantity and tank conditions. Revision markings throughout the document identify AES Revision 40 with the date May 01/12.

Fuel-System Maintenance Scope

The manual starts with fuel-system general information and then moves through the principal storage, distribution and indication functions. General fuel content includes the wing and center tank arrangement, control switches, engine and APU fire-button interfaces, ECAM displays, the refuel/defuel control panel, electrical power supplies, electrical symbols, interfaces and a fuel-system block diagram. The servicing material includes fuel safety procedures and approved fuels, while maintenance tasks include fuel-pipe removal and installation, tank-bonding inspection and bonding-strip repair.

Fuel tank work is treated as a substantial maintenance area in its own right. The storage and tanks sections include safety procedures for work in fuel tanks, dry-tank precautions, tank access, purge and vent procedures, water-drain and clack-valve work, microbiological contamination treatment, center-tank preservation, multiple fuel-tank leak-test methods, leak analysis, tank inspection and tank cleaning. The manual also contains illustrated tank and access details that support these procedures.

Ventilation and tank protection coverage includes the tank venting system, overpressure protectors, float vent valves, fuel-drain check valves, NACA vent components, the wing center tank external ventilating system, vapor seals, drain mast and leak monitor. The Chapter 28 material also addresses tank ignition prevention, including inspections of bonding leads, electrical wiring, FQI probe harnesses, fuel-pump canisters and center wing box areas.

Distribution and feed functions are covered from the main fuel-pump system through the APU fuel-pump system, crossfeed, engine LP fuel shut off and APU LP fuel shut off. Tasks include operational and functional tests, leak checks, pump and pressure-switch work, check and suction valves, air-release valves, sequence valves, fuel-pump canisters, water-scavenge jet pumps, strainers and the related actuator or valve removal and installation procedures. Refuel/defuel coverage extends to the control system and its associated couplings, diffusers, valves, actuators, panel components and checks.

The indicating portion of the Airbus A318 A319 A320 A321 Chapter 28 Fuel manual covers fuel quantity indicating, manual magnetic indicators and tank level sensing. Component coverage includes fuel-quantity probes, the fuel quantity preselector and indicator, the Fuel Quantity Indicating Computer, tank harnesses, magnetic level indicators, high/low level sensors, overflow and temperature sensing, and the Fuel Level Sensing Control Unit. This gives maintenance personnel a single Chapter 28 reference spanning the physical fuel system and the electrical sensing and indication functions that support it.

Together, these sections make the Airbus A318 A319 A320 A321 Aircraft Maintenance Manual Chapter 28 Fuel Rev 40 – 2012 a broad fuel-system maintenance reference rather than a single-component instruction. It links system operation with the procedures used to access, inspect, test, remove, install and service the components identified throughout Chapter 28, supported by component-location drawings, schematics, block diagrams and task illustrations.

Illustrated Procedures and System References

The document contains numerous pictorial pages that help connect task text with the actual system layout. Examples include the wing and center tank fuel-system figures, ECAM and control-panel illustrations, electrical power-supply schematics, system block diagrams, component-location figures, valve and pump details, tank-access views and maintenance drawings. These illustrations are especially useful when following a numbered Chapter 28 task because they show how the referenced valves, pumps, harnesses, tanks and controls relate to the wider fuel system.

The manual also includes procedures for leak testing, operational testing and functional checking across several Chapter 28 systems. Fuel-tank leak analysis and test methods, main fuel-pump tests, intercell transfer checks, recirculation-system checks, refuel/defuel system tasks and fuel quantity or level-sensing procedures are all represented in the contents. Removal and installation instructions are provided for many individual components, allowing the same reference to support both system-level diagnosis and component-level maintenance.

Maintain, Inspect and Test the Airbus A318-A321 Fuel System

Use this Airbus A318, A319, A320 and A321 Chapter 28 Fuel maintenance manual when work calls for the documented procedure rather than a generic fuel-system description. It supports fuel-tank servicing and access, pump and valve replacement, system inspections, leakage checks, operational and functional tests, refuel/defuel maintenance, fuel quantity indication work and tank-level sensing tasks. Following the correct task sequence, inspection criteria and system references matters when maintenance involves fuel containment, transfer, venting, electrical interfaces and indication.
