Technical Service Bulletin S19ZI — 2020 BLUE BIRD VISION SCHOOL BUS

Overview: Blue Bird and HSM Quality/Engineering teams have determined that the NextGen seats shipped from September 19, 2017 to March 21, 2019 have exposed holes in the rear side of the seat back frame that can allow a passenger(s) to insert their finger into the holes and possibly get their finger stuck. The number of exposed holes varies with the seat size. Only those holes directly visible to the passenger require plugs. The rear row seats are excluded. HSM has developed a Voluntary Technical Service Bulletin (S19ZI) for the installation of the hole plugs. HSM will provide parts at no cost. No labor will be reimbursed for the installation of the plugs. Affected Units: This service bulletin includes 2018 through 2020 Blue Bird All American and Vision School Buses manufactured from September 19, 2017 through March 21, 2019. Additionally, this service bulletin includes 2019 through 2020 Blue Bird All American and Vision Non-school buses manufactured from June 29, 2018 through February 16, 2019. A separate printout will be provided listing all buses in your territory that are affected by this service bulletin. Service Bulletin S19ZI will be mailed to all owners on record. Be sure to review your list and advise of any incorrect owner names and/or addresses. Repair Parts: HSM will provide parts at no cost. Please remit requests for parts to Blue Bird via [email protected] using the Service Bulletin S19ZI Kit Order Card and include the Blue Bird Body Number on all documentation. Parts are currently available in limited quantities.
