NOVA BUS Download PDF Report
Nova Bus submitted a model LFS diesel powered 38 seat/40-foot bus, for a partial STURAA test in the 12year/500,000 mile category. The Federal Transit Administration determined that the following tests would be performed; Check-In, Section 1.2 Servicing, Preventative Maintenance, and Repair and Maintenance during Testing, and Section 5.7 Structural Durability Test. The odometer reading at the time of delivery was 0,847.0 miles. Testing started on April 26, 2000, and was completed on August 8, 2000. 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 started on April 26, 2000 and was completed on August 7, 2000.
The interior of the bus is configured with seating for 38 passengers including the driver. Free floor space will accommodate 42 standing passengers resulting in a potential load of 80 persons. At 150 lbs per person, this load results in a total vehicle weight of 39,010 lbs and exceeds the GAWR (13,558 lbs) of the front axle. In order to avoid exceeding the axle weight rating, ballast simulating 4 standing passengers (600 lbs) was removed. Elimination of the 4 standing passenger positions resulted in an adjusted gross vehicle weight of 38,570 lbs. The SLW segment of the Structural Durability Test was performed at 33,070 lbs and the final segment of the test was performed at a CW of 27,610 lbs. Durability driving resulted in several failures that required unscheduled maintenance. There were no Class 1 or Class 2 failures. Of the 26 reported failures, 23 were Class 3 and six were Class 4. A complete and detailed listing of failures and related photographs are included in section 5.7 Structural Durability. During the coarse of Durability Testing, the manufacturer removed the test bus from testing to upgrade the material in the rear radius rod attachment plate from 304L stainless steel to 208 stainless steel, no dimensional changes were made. The period of time required for this off-site modification was from June 1, 2000 to June 6, 2000.
