1. Aviation Maintenance Management Introduction

2. IntroductionIntroduction  The Flight Line is a business  Approx 1 billion will travel by end of decade  Commerce, mail, defense and logistics by air  20% of every revenue dollar is maintenance  Early days one person knew all systems  Today systems very complex and interdependent  Competing priorities and dwindling resources require expert management

4. IntroductionIntroduction  Aviation in the Beginning l Today’s aircraft cargo holds are longer & sit higher than the Wright Brother’s first flight  Flight – 120 ft in 12 sec with an altitude of 10ft  747 freighter – 150 ft inside & sits16 ft off the deck

6. IntroductionIntroduction  Safest Mode of travel l Walking is far more dangerous than flying or driving, per mile traveled: l 0.16 deaths per 100,000,000 miles aboard an airplane. l 1.4 deaths per 100,000,000 miles in a car. l Almost 50 deaths per 100,000,000 miles walked.

7. Which type of flying is safer? Type of Flight Fatalities per million flight hours Airliner (Scheduled and nonscheduled Part 121)4.03 Commuter Airline (Scheduled Part 135)10.74 Commuter Plane (Nonscheduled Part 135 - Air taxi on demand)12.24 General Aviation (Private Part 91)22.43 Sources: NTSB Accidents and Accident Rates by NTSB Classification 1998-2007

8. Odds of being involved in a fatal accident Odds of being on an airline flight which results in at least one fatality Odds of being killed on a single airline flight Top 25 airlines with the best accident rates 1 in 5.4 million Top 25 airlines with the best accident rates 1 in 9.2 million

9. Accidents and Fatalities by Phase of Flight

10. Early days of Aviation  “If God had meant for man to fly He would have given us wings.”  Many early pioneers: l Octave Chanute, Otto Lilienthal, Samuel P. Langley, Glenn Curtiss & Orville & Wilbur Wright l Most intriguing problem was finding a power plant that provided the sufficient power-to-weight ratio for flight l Wright Brothers (recognized as first) both engineers & mechanics  Made 4 flights (Dec. 17, 1903,, Kitty Hawk, NC) 4 th was 59 sec. for over 852 feet.  Designed own engine, propeller, & aerodynamic tables  First maintainers – they melted cement to repair nut holding the propeller shaft sprockets in place

11. Promotion of Flight  First airline in US carried passengers from St. Petersburg to Tampa (Jan – Mar 1914) l Carried only 1 passenger at a time

12. Promotion of Flight  After WWI, airmail service began – if room, a passenger may sit upon the mail  US Gov’t encouraged operators to use bigger planes & carry more passengers so they wouldn’t have to rely on mail contracts to stay in business  Early days – no navigational aids (only roads, railways), could not fly at night unless bonfires lit along the route  By 1929, 10,000 miles of lighted airways, 275 lighted airports, 1352 navigational beacons

13. Promotion of Flight  1927 – 18,679 flew; 1931 – 385,000 flew  After WWII, US fostered the jet age  Aircraft became bigger and flew “higher, faster, and farther”  Nav aids both on ground and in the aircraft and satellites revolutionized the industry  Drastic improvements in aircraft and engine technology  Aviation has come of age l People can fly in comfort and safety

14. Early Aviation Maintenance  No such thing as scheduled maintenance l Spark plug cleaning and occasional oil change  WWI French pilot cut engines to allow him to sweep down and drop bombs l Couldn’t restart because he failed to “burn” the oil off the spark plugs by blipping his ignition switch – forced to land he was captured l The “standard” practice was to land, remove, and clean plugs

15. Early Aviation Maintenance  Wright Brothers favored simple skid landings over wheeled gear (gain in power-to-weight ratio) l Resulted in structural damage (On Condition)  Never performed preflight or post flight tasks l Simple look to see any hanging or items missing l No inspections of the structural elements (dry rot, cracking, corrosion) l Repair or replace as required  Instrumentation was simple – no inspections

16. Early Aviation Maintenance  Modern Approach is more sophisticated  Aircraft are designed for: l Safety l Airworthiness l Maintainability  Detailed Maintenance program is developed with every new model aircraft or derivative

17. Technical Management  Several Disciplines to properly conduct maintenance at an airline: l Maintenance  Hands-on, “nuts and bolts” labor l Engineering  Design, analysis and tech assist to support maintenance work l Management  Organization, Control, and Administration of the maintenance operation

18. Technical Management  Several Disciplines to properly conduct maintenance at an airline: l Production Planning  Planning concepts and organization activity to effectively plan all work l Logistics  Understanding the aircraft inventory scope, realistic, futuristic to meet demand for parts required for successful maintenance operation l Technical Training  Meet all maintenance tech training of personnel

19. Aviation Industry Interaction  Must meet FAA regulations for maintenance before releasing an aircraft for service  Aircraft manufacturers, makers of onboard equipment and systems, airline operators, industry trade associations, regulatory authorities, flight crews, and maintenance personnel l Work together to ensure aviation safety l From the design of the aircraft and its systems, through development of maintenance programs and continues throughout the lifetime of the aircraft

20. Layout of Book  Part 1: Fundamentals of Maintenance l Chapters 1 – 7  Part 2: Technical Services l Chapters 8 – 11  Part 3: Aircraft Management, Maintenance, and Materiel Support l Chapters 12 – 15  Part 4: Oversight Functions: l Chapters 16 – 19  Part 5: Appendixes l Appendix A - F

21. SummarySummary The purpose of aircraft maintenance is to ensure the aircraft will remain airworthy throughout its operational life
