MRB Report

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 PROPOSALthat is acceptable to the Maintenance Review Board (MRB).

Once approved by the MRB, this proposal becomes the

2. Evolution of Evaluation Methods

• Development of the MSG methodology

“Airline and manufacturer experience in developing scheduledmaintenance for new aircraft has shown that more efficient programscan be developed through the use of logical decision process”

MSG-3 Document

Objective = To present a means for developing the scheduledmaintenance tasks and intervals which will be acceptable to theregulatory authorities, the operators, and the manufacturers.

The MSG-3 method is a tool to develop scheduled maintenance tasks

With MSG-3, the scheduled requirements will be developed via a guidedlogic 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.

The terms ‘Hard-Time’, ‘On-Condition’ and ‘Condition Monitoring’ are not used in MSG-3 Logic.

Items that, after analysis, have no scheduled task specified, may be monitored by an operator’s reliability program.

The Operator / Manufacturer Scheduled Maintenance DevelopmentDocument “MSG-3” is written by the Maintenance Steering Group - 3Task Force organized under the leadership of the ATA.

The working portions of MSG-3 document are contained in 4sections, each of which contains its own explanatory material anddecision logic.

• Systems / Powerplant, including components and APU’s

• Aircraft structure• Zonal inspections• Lightning / High Intensity Radiated Field (L / HIRF)

The Maintenance Review Board (MRB) is responsible for approving the initial minimum scheduled maintenance requirements, which are contained in the MRB Report and revisions

MRB Process – Organization / duties

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.

• The Airworthiness Limitations Section (ALS) is part of the compliance to the Instructions for Continuous Airworthiness required by CS 25.1529, Appendix H, paragraph 25.4.

• The ALS is the repository for stand-alone documents that are approved independently from each other, by the TC auth.

• It comprises the following documents (depending on a/c program):

- ALS Part 1 : Safe Life Airworthiness Limitations Items- ALS Part 2 : Damage Tolerant Airworthiness Limitations Items- ALS Part 3 : Certification Maintenance Requirements- ALS Part 4 : Ageing System Maintenance- ALS Part 5 : Fuel Airworthiness Limitations- ALS Part 6 : Aircraft Information System Security

Compliance with the requirements promulgated in these documents is mandatory.
