Description

Canadair Regional Jet Aircraft Maintenance Manual Chapter 33 Lights – December 2005

This Canadair Regional Jet Aircraft Maintenance Manual Chapter 33 Lights – December 2005 provides extensive maintenance information for the aircraft lighting systems grouped under ATA Chapter 33. The material covers lighting used in the flight compartment, passenger compartment, service and maintenance areas, on the exterior of the aircraft, and throughout the emergency lighting system. It is structured as a working aircraft maintenance reference, combining system description and operation sections with component-location information, operational tests, removal and installation tasks, adjustments, inspections, safety precautions, and illustrated maintenance figures.

The chapter is particularly detailed because the Regional Jet lighting system is divided into many independent circuits and individual components. Procedures identify applicable circuit breakers, electrical connectors, access areas, lighting control panels, power units, dimmers, transformers, relays, lamps, switches, signs, battery packs, inverters, chargers, and emergency-light assemblies. Aircraft effectivity is stated throughout the chapter where configurations differ, allowing maintenance personnel to determine which procedure and component arrangement applies to the aircraft being serviced.

Lighting System Maintenance Coverage

The Canadair Regional Jet Chapter 33 Lights manual begins with an overall description of how the aircraft lighting circuits are arranged and powered. It explains the relationship between the AC and DC buses and the lighting circuits and identifies the principal lighting groups used throughout the aircraft. This provides the system-level background needed before working on individual lights, panels, dimmers, transformers, relays, signs, or emergency-light components.

Flight-compartment coverage includes panel floodlighting, integral panel lighting, display and control-panel illumination, map and chart-holder lights, standby-compass lighting, and floor floodlights. The chapter identifies where these components are installed and how their brightness controls operate. For the panel floodlighting system, for example, the manual includes component-location illustrations, a simplified electrical schematic, an operational test, and removal and installation procedures for the individual panel floodlights.

The passenger-compartment section is extensive and deals with the lighting encountered by passengers and cabin crew. It covers ceiling and sidewall illumination, reading lights, flight-attendant and boarding lights, passenger information signs, lavatory lighting, and galley lighting. Power units, dimmers, relays, switches, lamp assemblies, and control panels are treated as separate maintenance subjects where required. Many of these procedures contain aircraft-effectivity statements because equipment configuration varies between aircraft.

IMAGES PREVIEW

Service and maintenance lighting is also included. This part of the Canadair Regional Jet Aircraft Maintenance Manual Chapter 33 Lights addresses lighting used in cargo, avionics, equipment, and wheel-well areas during servicing or maintenance operations. Exterior-lighting coverage then moves to the systems required for ground operation, flight visibility, inspection, and collision avoidance, including landing, taxi/recognition, navigation, wing inspection, anticollision, beacon, stair, and logo lights.

The emergency-lighting portion includes the normal Chapter 33 system description together with individual emergency-light components. Floor-track lights, emergency battery packs, charger assemblies, inverters, lighted exit signs, ceiling and floor-level emergency floodlights, and exterior emergency lights are covered through dedicated maintenance subjects. This gives technicians a single chapter for both the normal aircraft lighting equipment and the emergency illumination system.
