Maintenance management systems
Accredited bus operators must develop their own maintenance management system (MMS) based on their own operating conditions, risks, incident history and determined safety objectives.
The purpose of an MMS is to ensure, so far as is reasonably practicable, that each bus operated by an accredited bus operator is safe and roadworthy whenever it is carrying passengers.
An MMS is applicable to accredited operators of a commercial or a local bus service, and persons who are accountable to the accredited operator for the maintenance and repair of buses.
An accredited bus operator must establish and maintain a system for ensuring that the buses they operate are maintained in accordance with the following requirements.
Requirements
The MMS may assist an accredited bus operator to meet its obligations under the Bus Safety Act and associated regulations. There are separate requirements for:
- Accountabilities and authorities
- Competence
- Maintenance
- Inspections
- Defect reporting and clearance
- Records.
Accountabilities and authorities
The accountabilities and authorities for persons involved in all activities associated with an MMS must be clearly defined and documented.
Competence
Each person who has a role under an MMS must be appropriately trained and have the required competence to perform that role.
Maintenance
An MMS must prescribe maintenance activities as specified by the manufacturer or other sources deemed appropriate by the accredited bus operator.
Inspections
Pre-trip inspections
An MMS must prescribe an inspection regime for pre-trip inspections which includes the following items:
- A requirement that inspections are completed prior to the first passenger carrying trip on each operating day
- Clear identification of the person undertaking the inspection, the date, bus details and result of the inspection
- A system to ensure and record that each bus is checked in accordance with a checklist
- A checklist that references any documentation deemed appropriate by the operator
- A requirement that a bus is not operated if any defects are identified.
Vehicle safety inspections
An MMS must prescribe an inspection regime for vehicle safety inspections (VSIs) which includes a specification that the maximum permissible inspection interval is:
- As specified by the vehicle manufacturer and or reference to any other relevant source
or - In the event where the manufacturer does not specify inspection intervals or other relevant source is unavailable, three months (plus or minus seven days) or a specified travel distance, whichever occurs first.
Annual bus safety inspections
An MMS must prescribe an inspection regime for annual bus safety inspections which includes a requirement that:
- An accredited bus operator must ensure that each bus used to provide a commercial bus service or local bus service undergoes a safety inspection in accordance with the regulations annually, or at prescribed intervals
- The date of the first annual bus safety inspection is the anniversary date for each bus and the inspection must be completed annually.
Following industry consultations, an annual safety inspection (ASI) may now be substituted for one of the required quarterly vehicle safety inspections (VSI) by complying with this guidance.
The reverse, however, is not the case, a VSI may not be undertaken in place of an ASI. All operators must ensure that each bus used to provide a service undergoes an ASI.
The following guidance outlines the requirements and examples should you decide to introduce the process into your maintenance management system.
Note 1 - Accredited bus operators
Accredited bus operators must use the appropriate references to develop an inspection regime of sufficient detail to satisfy themselves that the buses within their fleet are safe and roadworthy at all times.
References must include, but are not limited to, vehicle manufacturer's specifications, national heavy vehicle inspection manual and any applicable legislation or vehicle standards.
Note 2 - To assist accredited bus operators
To assist accredited bus operators to determine the appropriate frequency of vehicle safety inspections for the buses in their fleet, the age of a bus shall be determined in the following manner:
- For an Australian manufactured new bus: the date of registration of body or chassis, whichever is earlier
- For an Australian manufactured second hand bus: the date of first registration of body or chassis, whichever is earlier
- For an imported new bus: the date of registration of body or chassis, or Australian compliance plate, whichever is earlier
- For an imported second hand bus: the date of manufacture of body or chassis, whichever is earlier.
Defect reporting and clearance
An MMS must establish processes to identify, record, report and address defects in buses. An MMS must contain the following processes and treatments for defects:
- Method(s) for preventing a bus from use until any defect(s) are repaired
- References must include, but are not limited to, vehicle manufacturer's specifications, national heavy vehicle inspection manual and any applicable legislation or vehicle standards, for the development and maintenance of inspection checklists and for defect identification
- Recording and reporting procedures for any defect discovered during operation, so far as is reasonably practicable, to ensure that appropriate action is taken in relation to that defect.
Records
Records of all activities associated with an MMS must be identified and maintained in English and held for a minimum of three years.
References
Accredited bus operators should reference these documents when developing their MMS:
