What is the difference between MSG-2 and MSG-3?
MSG-2 was process orientated and used a bottom-up approach. It also introduced ‘condition monitored maintenance’ concept. Unlike MSG2, MSG3 is a task orientated and this eliminated the confusion associated with the different interpretations of ‘Condition Monitoring’, ‘On-condition’ and ‘Hard time’.
What are the levels of MSG-3 inspections?
Please consider the following MSG-3 inspection types:
- Lubrication-Servicing (LU-SV)
- Operational-Visual Check (OP-VC)
- Inspection-Functional Check.
- Specific Inspection Types.
- General Visual Inspection (GVI)
- Detailed Inspection (DET)
- Special Detailed Inspection (SDI)
- A Stand-alone General Visual Inspection (GVI)
What is the difference between MSG 1 and MSG-2?
The MSG-1 process used decision logic to develop scheduled maintenance. MSG-2 was developed and used for developing scheduled maintenance for 1970’s, MSG-2 was process orientated and for first time introduced ‘condition monitored maintenance’ concept.
What is MSG aircraft maintenance?
MSG stands for Maintenance Steering Group (3 is the 3rd version of the process and has been around since 1980). It provides a process which is used for developing scheduled maintenance tasks and intervals, which will be acceptable to the regulatory authorities, the operators and the manufacturers.
What are task descriptions of the MSG-3 can be assigned categories?
The MSG-3 guidelines provide logic designed to assign each functional failure effect to one of five categories: Evident Safety, Evident Operational, Evident Economic, Hidden Safety, Hidden Non-Operational (or Hidden Economic).
What is maintenance Steering Group 3?
Maintenance Steering Group-3 (MSG-3) is a method for developing preventive maintenance programs in the aerospace industry. The process is maintained by A4A (Airlines For America formerly known as ATA). A decision tree is then applied to decide the maintenance strategy for each SSI.
What is structurally significant item?
“Structurally Significant Item (SSI) is defined as a structural detail, element or assembly which is judged significant because of the reduction in aircraft residual strength or loss of structural function which are consequences of its failure.”
What are the 3 MSG in aviation?
MSG-3 (Maintenance Steering Group) ‘Operator/Manufacturer Scheduled Maintenance Development’ is a document developed by the Airlines For America (A4A) (formerly the Air Transport Association or ATA).
How long is Metal Gear Solid 3?

What is MRBR in aviation?
a. An MRBR contains the minimum scheduled tasking/interval requirements for a particular aircraft and on-wing engine maintenance programs. Develop the MRBR in accordance with the guidelines in this advisory circular (AC).
What are maintenance schedules?
Maintenance scheduling refers to the timing of planned work, when the work should be done and who should perform it. It offers details of “when” and “who.” Scheduling is meant to: Schedule the maximum amount of work with the available resources.
What is maintenance steering approach?
What do you need to know about MSG 3?
MSG-3 expected the assessment of functional failures and the assignment of the consequences of those failures into two basic categories, ‘SAFETY’ and ‘ECONOMIC’. Unlike MSG2, MSG3 is a task orientated and this eliminated the confusion associated with the different interpretations of ‘Condition Monitoring’, ‘On-condition’ and ‘Hard time’.
How old is MSG ( Maintenance Steering Group ) logic process?
A briefing document presented by Steven Bentley www.sassofia.com The MSG (Maintenance Steering Group) Logic Process is now over 40 years oId. (MSG-3 is 30 years old) Consider that if we extrapolate backwards from the introduction of MSG we reach the 1930’s.
What does MSG-3 stand for in maintenance category?
MSG-3 is widely used to develop initial maintenance requirements for modern commercial aircraft which are published as a Maintenance Review Board Report (MRBR). It has two Volumes (1 for Fixed Wing Aircraft and 2 for Rotorcraft), and its application will proceed alongside the Type Certification process.
What was the purpose of the MSG-1 process?
The MSG-1 process used decision logic to develop scheduled maintenance. MSG-1 / MSG -2 introduced three control process. Hard Time limit: Maximum interval for performing maintenance tasks on a part or unit.
