Document Review
The maintenance plan shall be reviewed every 12 months by a competent engineer.
The plan shall include:
A process for it to be regularly reviewed for potential to improve its effectiveness.
A process for a record to be kept of decisions taken at each review.
A process for the maintenance instruction to also be reviewed in the light of the following:
i) In process reviews of maintenance activities
ii) Performance of the machines and components covered by the instruction, including relevant
national incident reports
iii) Changes in the pattern of use and operating environment
iv) Manufacturer's advice
v) Network Rail directives
vi) As part of the seven-year review of the machine
vii) Fault logs and GE/RT8250 NIRs
A key element in the development of a successful maintenance instruction is a commitment to review regularly
both the frequency and content of each job description. A nominated competent engineer identified by the
owner should review the maintenance instruction, as a minimum, every 12 months, and the records retained
for audit purposes.
Each component failure should be assessed to establish if there is a failure of maintenance that either caused
or contributed to the failure. The maintenance instruction should then be amended to reflect the lessons
learnt.
Regular reviews of the performance of the machine, reviews of maintenance activities, changes of use or
frequency of use of the machine, and external information, could all lead to changes in the instruction.
Each change of the instruction should be authorised by a nominated competent engineer and, where
reasonably practicable, the change should be agreed by the OEM. The amended instruction needs to be re-
certificated. It is recommended that the instruction is kept as a live document, with each change authorised by
the competent engineer, who should decide if the amendment is serious (and requires recertification
immediately), or whether several changes can be bundled together and re-certificated at an annual review.
The users of the maintenance instruction should be encouraged to contribute to the review process.
