Neoplan USA Corporation submitted a model AN 440L, diesel powered 38 seat/40- foot bus, for a partial STURAA test in the 12yr/500,000 mile category. The Federal Transit Administration determined that the following tests would be performed: 2. Reliability and 5.7 Structural Durability Test which includes 1.2 Servicing, Preventive Maintenance, and Repair and Maintenance. The odometer reading at the time of delivery was 55,560 miles. Testing started on November 13, 2000 and was completed on February 23, 2001. The Check-In section of the report provides a description of the bus and specifies its major components.
The primary part of the test program is the Structural Durability Test, which also provides the information for the Maintainability and Reliability results. The Structural Durability Test was started on November 13, 2000 and was completed on February 21, 2001.
The first segment of the Structural Durability Test was performed with the bus loaded to a GVW of 40,100 lbs. In order to avoid exceeding the GAWR (26,000 lbs) of the rear axle, ballast for 12 rear standing passengers was eliminated. The reduction from full capacity resulted in an adjusted measured gross vehicle weight of 40,100 lbs and was used for all dynamic testing. The middle segment was performed at a SLW of 35,100 lbs. The final segment was performed at a curb weight of 29,600 lbs. Durability driving resulted in unscheduled maintenance that included a variety of subsystem failures. These unscheduled maintenance and failure events can be found in a complete and detailed listing of scheduled and unscheduled maintenance, which is provided in the Maintainability section of this report.
The Reliability section compiles failures that occurred during Structural Durability Testing. Breakdowns are classified according to subsystems. The data in this section are arranged so that those subsystems with more frequent problems are apparent. Also the problems also are listed by class as defined in section 2. The test bus encountered no Class 1 or Class 2 failures. Of the twenty reported failures, seventeen were Class 3 and three were Class 4.
