Pneumatic Wing Anti-Ice Operation & Component Servicing
The pneumatic wing ice protection system documented in this Airbus A318 A319 A320 A321 Aircraft Maintenance Manual – Chapter 30 Ice and Rain Protection utilizes engine bleed air extracted downstream of the precooler. Hot compressed air is delivered along the wing fixed leading edge to thermal anti-icing piccolo tubes inside slats 3, 4, and 5. Technicians will find complete functional descriptions of the electro-pneumatic wing anti-ice valves (FIN 9DL on the left wing and 10DL on the right wing), which are spring-loaded to the safe closed position in the event of electrical power interruption. The manual outlines the precise regulating parameters: valves maintain downstream air outlet pressure at 1.55 bar (22.48 psi) ± 0.17 bar (2.46 psi), with internal pressure switches triggering ECAM fault warnings if supply pressure drops below 0.9 bar (13.05 psi) or exceeds 2.2 bar (31.9 psi).
Detailed step-by-step procedures outline how to safely remove, inspect, and reinstall wing anti-ice control valves, including coupling torque specifications of 0.39 to 0.51 m.daN (34.5 to 45.1 lbf.in), locating pin engagements, and scheduled replacement of the integrated anti-ice valve filter (Material No. 19-010 lockwire and replacement O-rings). Furthermore, the maintenance text covers the complete maintenance sequence for the track 7 telescopic duct assemblies, guiding mechanics through extension, link rod torquing (0.6 to 0.9 m.daN / 53.1 to 79.6 lbf.in), alignment pins, and operational slat travel checks.

MMEL Valve Deactivation & Ground Testing Standards
When unexpected valve malfunctions occur on the line, maintaining operational dispatch capability is paramount. This manual provides direct compliance procedures for Master Minimum Equipment List dispatch under ATA 30-11 and ATA 30-21. Mechanics are guided through deactivating and securing the wing anti-ice control valves 9DL and 10DL in the CLOSED position using the integrated manual locking pin, lockwire (0.8 mm stainless steel annealed), and mandatory cockpit placards. For right-hand wing valve 10DL, deactivation to the OPEN position is fully detailed, highlighting specific flight operation limitations and slat overheat precautions.
Similar MMEL procedures govern the nacelle anti-ice valves (FIN 4000DN) on engine air intakes, including mechanical manual override limits (maximum 50 lbf.in / 0.56 m.daN applied to the hexagonal shaft nut) and locking pin placement. In addition, the guide provides comprehensive instructions for the 30-second ground operational test of the wing anti-ice system, complete with relay timing checks (relay 4DL and 5DL) to prevent thermal damage to extended slats, as well as ground leak testing instructions utilizing external Ground Air Power Carts connected to the high-pressure receptacle on access panel 191DB.
Electrical Probe, Window Heat & Waste Water Heating Systems
Beyond pneumatic thermal systems, this manual provides detailed coverage of the high-amperage electrical de-icing networks managed by dedicated avionics computers. Technicians gain access to wiring and sensor diagrams for the Probe Heat Computers (PHC 1, 2, and 3), controlling 115V AC supplies to pitot probes, Angle of Attack sensors, and TAT sensors, alongside 28V DC power routed to static ports. Ground/flight detector logic, automatic probe heat startup upon first engine start, and ground temperature attenuation are fully mapped.
The flight deck windshield anti-icing and defogging chapter details the construction and heating circuits of front laminated glass (incorporating chemical-reinforced plies and continuous heating films) and side acrylic windows. Temperature regulation by the dual Window Heat Computers (WHC 1 and 2) is documented with sensor resistance charts holding temperatures between 35°C (95°F) and 42°C (107.6°F). Complete removal, installation, and inspection routines are also provided for two-speed windshield wiper motor converters, rain repellent solenoid valves, and fuselage waste-water drain masts (4DU and 14DU), ensuring total aircraft dispatch readiness in cold-weather and icing conditions.
Professional Technical Capability & Instant PDF Delivery
Carrying the correct OEM technical documentation is vital for ensuring aviation safety, structural integrity, and strict airworthiness compliance. The Airbus A318 A319 A320 A321 Aircraft Maintenance Manual – Chapter 30 Ice and Rain Protection equips licensed aircraft maintenance technicians, avionics specialists, base maintenance supervisors, and flight operations personnel with the precise instructions required to diagnose faults, replace line-replaceable units (LRUs), perform leak checks, and execute MMEL deactivations safely. Utilizing genuine maintenance specifications prevents accidental pneumatic duct blowouts, avoids expensive slat thermal deformation, and guarantees proper rigging of telescopic joints and flight control interlocks.
Delivered as an instant high-resolution PDF download immediately following purchase, this manual requires no waiting for physical media. It can be accessed on demanding ramp environments, line stations, or workshop tablets, laptops, and desktop computers, and is fully printable for inclusion in physical maintenance work orders and task sign-off packets.
