Attention Blue Bird:
HSM in conjunction with Blue Bird Quality and Engineering have reviewed and found a potential
concern both parties wish to address.
In response, Blue Bird Quality/Engineering and HSM Quality/Engineering have reviewed and
identified visible holes that HSM has agreed to plug.
HSM has developed a Voluntary Technical Service Bulletin (S19ZI) and agreed to provide parts at
no cost on seats not equipped with these plugs. As this is voluntary, there will be no
reimbursement of labor for performing this Service Bulletin. In conversations in conjunction
with Blue Bird Engineering, all other aspects of the Service Bulletin will be handled by Blue Bird

HSM has the parts on hand to cover those seats shipped to Blue Bird. Limited quantities of the parts
