Description

FlightSafety Dash 8 Q400 Maintenance Training Manual Volume 1 Rev 0.5 (2015)

The FlightSafety Dash 8 Q400 Maintenance Training Manual Volume 1 Rev 0.5 (2015) is the first volume of the FlightSafety International Maintenance Training Manual (MTM) used with Bombardier Q400 maintenance initial courses. Volume 1 is arranged in ATA-100 chapter order and covers ATA 100, 5-12, 20, 24, 31 and 45. It describes the Q400 / Q400 NextGen airframe, systems layout, ramp handling and selected system operation so technicians can learn terminology, safety precautions, component locations and condensed maintenance practices. The MTM is for familiarization and training only. Condensed tasks in this book do not replace the Aircraft Maintenance Manual, Structural Repair Manual, Component Maintenance Manual or Maintenance Requirements Manual. If data here conflicts with the manufacturer or the FAA, the manufacturer or FAA publication takes precedence.

The introduction presents the Dash 8 Q400 as a twin turboprop with a Thales avionics suite, optional Head Up Guidance System for Category III approaches, Pratt & Whitney Canada PW150A engines with FADEC, and Dowty R408 six-bladed composite reversible-pitch propellers of 13 ft 6 in (4.11 m) diameter. Crew is two plus two or three flight attendants; passenger capacity is listed as 68 to 78 at 30–34 in (76–86 cm) seat pitch.

Engine ratings printed in the general data tables are normal takeoff 4,580 shp, maximum 5,071 shp, maximum cruise 3,947 shp and maximum climb 4,058 shp. External dimensions include overall length 107 ft 9 in (32.84 m), wingspan 93 ft 3 in (28.42 m), overall height 27 ft 5 in (8.34 m) and fuselage maximum diameter 8 ft 10 in (2.69 m). Cabin length excluding the cockpit is 61 ft 8 in (18.80 m) with maximum height 6 ft 5 in (1.95 m) and cabin pressurization 5.5 psi (37.9 kPa). Fuel capacity is given as 1,724 U.S. gal (6,526 L); oil capacity is 8.0 U.S. gal (30 liters) per engine. Weights include maximum takeoff 64,500 lb (29,257 kg), maximum landing 61,750 lb (28,009 kg), maximum zero fuel 57,000 lb (25,855 kg), operating weight empty 37,888 lb (17,185 kg) and maximum payload 19,112 lb (8,670 kg). Maximum cruise speed is 360 kts; maximum operating altitude is 25,000 ft (7,620 m), with an optional ceiling of 27,000 ft (8,230 m). Structural figures assume a 50-minute flight: crack-free life 40,000 flights / 32,670 flight hours and design life 80,000 flights / 65,340 flight hours. Line checks are listed every 50 flight hours and structural inspection every 40,000 flights.

How the MTM Relates to OEM Manuals

Chapter 100 explains that the Aircraft Maintenance Manual is written to ATA-100 Revision 34 and is split into a System Description Section and Practices and Procedures. Page blocks follow the familiar 1–99 description, 201–299 maintenance practices, 301–399 servicing, 401–499 removal/installation, 501–599 adjustment/test, 601–699 inspection/check, 701–799 cleaning/painting and 801–899 repairs pattern. AMTOSS seven-element task numbers, equivalent-tool rules, consumable-material references to PSM 1-84-18, and the definitions of WARNING, CAUTION and NOTE are all introduced here so course students can navigate Bombardier publications after class. The MTM itself states that any maintenance performed on the aircraft must use approved OEM documentation.

Electrical Generation, Fault Codes and CDS Diagnostics

ATA 24 is the longest chapter in this volume. It walks through battery contactors and emergency isolation by the EPCU, main 28 VDC starter-generators and TRUs, APU 28 VDC generation, DC and AC external power receptacles, and variable-frequency 115 VAC generation from the propeller reduction gearboxes. Block diagrams show source-fault and bus-fault logic, including dual-generator and dual-TRU loss cases and MMEL dispatch with a failed generator. Fault-code tables are tied to the battery system, DC generation and distribution, APU DC generation, DC external power, AC generation and distribution, and AC external power. Operational checks are written for batteries, DC generation, GCUs, EPCU, SBCB, APU 28 VDC generation, AC contactors and external power connect/remove sequences.

ATA 45 then shows how the Central Diagnostic System talks to the Integrated Flight Cabinets, EIS, air-data units, radios and selected non-avionics computers. Students see the ARCDU last-leg report, previous-legs report, system report/test pages, LRU identification pages and avionics configuration sheets, plus how to set CDS maintenance mode from the wardrobe-compartment switch and how to reset NVM messages for other systems from the maintenance panel.

Ground Handling, Zoning and Standard Practices

Aircraft general chapters cover jacking at fuselage and axle points, weighing and leveling, towbar and towbar-less towing including flat-tire movement, taxi turning radii, propeller and exhaust danger areas, nose-gear and main-gear lock pins, static grounding, storage with humidity indicators and engine preservation, and mooring with published wind-speed and direction limits. Zone maps divide the airplane into major zones 100 through 400 with sub-zones for underfloor, cabin, empennage and nacelle work. ATA 20 collects the everyday airframe practices that appear on many job cards: approved markers, pitot drain-hole cleaning limits (do not insert more than 0.118 in / 3 mm of nylon wire), control-cable inspection, approved permanent fittings for rigid lines, ESDS wrist-strap and conductive-bag handling, connector lubricants and Geltek tape, degaussing, and the vacuum anchor system used as person-rated fall-arrest anchorage.

Use This Manual for Training and System Familiarization

The FlightSafety Dash 8 Q400 Maintenance Training Manual Volume 1 Rev 0.5 (2015) supports identification of safety precautions, ramp and transit servicing, system layout and nomenclature, special tooling awareness, normal and abnormal system function, and use of MEL/CDL-style airworthiness thinking as listed in the Bombardier Q400 MI course objectives. Correct electrical isolation, ESDS handling, jacking and towing limits, and CDS report interpretation matter because condensed classroom procedures still point at real contactors, generators, recorders and diagnostic menus on the airplane. After payment you receive an instant PDF download with no shipping. Open it on any device and print the pages you need for study or shop reference. Always confirm live maintenance against the current manufacturer AMM and related Bombardier manuals before work on the aircraft.
