Scheduled Maintenance Requirement MRB Process Initial scheduled maintenance requirements establishment requires collaborative work, in order to combine knowledge and experience, between : • Customer airlines • Aircraft manufacturer • Regulatory advisors The final aim is to compile a Maintenance Review Board (MRB) Report PROPOSAL that is acceptable to the Maintenance Review Board (MRB). Once approved by the MRB, this proposal becomes the MRB Report

Scheduled Maintenance Requirement 2. Evolution of Evaluation Methods MRB Process – MSG Methodology

• Development of the MSG methodology “Airline and manufacturer experience in developing scheduled maintenance for new aircraft has shown that more efficient programs can be developed through the use of logical decision process” The MSG-3 method is a tool to develop scheduled maintenance tasks

MSG-3 Document Objective = To present a means for developing the scheduled maintenance tasks and intervals which will be acceptable to the regulatory authorities, the operators, and the manufacturers.

Scheduled Maintenance Requirement MRB Process – MSG Methodology With MSG-3, the scheduled requirements will be developed via a guided logic approach and will result in a task-oriented program. The logic’s flow of analysis is failure-effect oriented : It does not start with an evaluation of proposed tasks but with the most important factor determining the task, namely the consequences of a functional failure. Items that, after analysis, have no scheduled task specified, may be monitored by an operator’s reliability program. The terms ‘Hard-Time’, ‘On-Condition’ and ‘Condition Monitoring’ are not used in MSG-3 Logic.

Scheduled Maintenance Requirement MRB Process – MSG Methodology The Operator / Manufacturer Scheduled Maintenance Development Document “MSG-3” is written by the Maintenance Steering Group - 3 Task Force organized under the leadership of the ATA.

The working portions of MSG-3 document are contained in 4 sections, each of which contains its own explanatory material and decision logic. • Systems / Powerplant, including components and APU’s • Aircraft structure • Zonal inspections • Lightning / High Intensity Radiated Field (L / HIRF)

Scheduled Maintenance Requirement MRB Process – Organization & Administration MRB Process – Organization / duties The Maintenance Review Board (MRB) is responsible for approving the initial minimum scheduled maintenance requirements, which are contained in the MRB Report and revisions The Industry Steering Committee (ISC) - establishes the policies (see PPH …), - directs the activities of the MWGs, - is responsible for the establishment of the MRBR Proposal. The ISC activities will be coordinated with the MRB Chair through the ISC Chair / Co-Chair The Maintenance Working Groups (MWG) will review, amend and endorse the MSG3 analysis proposals made by the manufacturer and provide an initial list of minimum scheduled maintenance tasks and intervals to the ISC. © AIRBUS S.A.S.
