  1. MGMT 580 – FINAL PROJECT Cesar A. Marrero

  2. Agenda • Introduction • Popularity of the Boeing 737 • Reliability Program • Failures of the Boeing 737 • Evaluation: Defective Wiring (TWA Flight 800) • Conclusion

  3. Introduction • Boeing 737 – the workhorse for low-fare airlines around the world • Easier and less expensive to maintain • Fewer parts than older models • Quick turnaround at the terminals

  4. Boeing 737 – Popularity • Over 7,500 aircraft delivered to date • Record-breaking orders of any model in a single year • 1,124 net orders of the next-generation version (models 700, 800, and 900) in 2012 • 914 orders for the 737 MAX version

  5. Reliability Program • Entire System • Common components reused in all airframes • Unchanged fuselage • Changes primarily to wing structure and engines • Airframe is quite cost-efficient • Redesigning fuselage would not provide much improvement • Increased costs with two separate production lines

  6. Reliability Program • Humans in the System • Commonality of airframes promotes familiarity • Training costs are significantly reduced • Employees use a common set of tools and procedures

  7. Reliability Program • Maintenance of the System • Interchangeable parts • Standard technical documentation • Longevity efforts

  8. Reliability Program • Simplicity of Design • Greater turnarounds for airline carriers • Maximize the use of their fleet • Low stance on the ramp • Easier to maintain and load • Servicing can be done at ground level • Baggage can be loaded from the ground • Last minute cargo/luggage additions

  9. Reliability Program • Redundant and fail-safe features • Two engines per aircraft, even though only one is needed to fly • Two electrical systems • Two fuel systems • Emergency Oxygen system • Triple Rudder system

  10. Reliability Program • Manufacturing Methods and Purchasing Requirements • Assembly line production, similar to the automotive industry • Accelerated production • Reduced production costs • Fewer order backlogs and customer waiting times

  11. Reliability Program • Maintenance of complete product or system performance records • Production and maintenance logs • Records failures, replacements, repairs, warnings, field tests, and operating conditions • Influences changes in the airframe • Improves manufacturing methods • Modifies quality checks • Identifies most reliable components • Extensive field testing before components are fielded

  12. Reliability Program • Communication • Valuable collaboration between customers, chief mechanics, and field service reps • Efforts ensure new version of 737 continues the trend of simplicity, reliability and low cost. • Airlines can choose a version of 737 with latest cockpit displays or commonality with older models

  13. Failures of the Boeing 737 • Events influenced dramatic changes in the inspection and maintenance process • TWA Flight 800 – Exploded, killing all on board • Southwest Flight 812 – Peeled exterior skin

  14. TWA Flight 800 • Exploded 12 minutes after take off • Boeing Model 747, not 737 • 230 on board killed • Cause determined to be faulty wiring • Spark caused ignition of fuel fumes • FAA ordered Boeing to inspect all airframes, especially the older 737 model

  15. Southwest Airlines Flight 812 • Loss of cabin pressure, caused crew to perform emergency landing • Cause determined to be manufacturing flaws on the fuselage skin • Rivet joints not aligned or overlapped, causing fatigue on external skin • Skin peeled off, causing a rapid loss of cabin pressure • Not first time skin peeled-off

  16. Evaluation of Defective Wiring Machinery / Equipment People • Cause and effect diagram: Aircraft Explodes Inexperienced maintainers Different fuel mixture Substandard cables Insufficient quality control Missing inspection steps Insufficient testing tools Inadequate testing tools Failure to detect defective cables Materials Methods

  17. Machinery / Equipment • Insufficient testing tools • NO tools available to detect fuel leaks • Inadequate testing tools • NO tools to detect electrical shortages

  18. Methods • Missing inspection steps • NO instructions on how to inspect for fuel leaks around electrical wiring • Insufficient quality control • NO formal QC oversight when inspecting the areas where fuel cells and electrical wiring are combined

  19. People • Failure to detect defective cables • NO training • Unable to physically view defective cables • Inexperienced maintainers • NO experienced workers/mentors

  20. Materials • Substandard cables • Outsourced cables delivered by sub-contractors • Different fuel mixtures • Lack of standard fuel operations at airfields world-wide

  21. Corrective Actions • FAA ensure corrective actions are complied with • Boeing ensures employees receive immediate maintenance notices • Boeing consider redesigning electrical wiring near fuel systems • Boeing consider improving fuel leak detectors

  22. Conclusion • “Reliability, or quality over the long term, is the availability of a product to perform its intended function over a period of time and under prescribed environmental conditions.” (Summers, 2010). • Based on this definition, the Boeing 737 has exceeded these conditions • Surpassed their intended function by extending its lifespan beyond the prescribed maximum of 75,000 flights.
