Über diese Lernkartei

Diese Lernkarten behandeln die Grundlagen der Flugzeugwartung und -systeme auf Universitätsniveau. Sie konzentrieren sich auf Wartungsstrategien wie MSG-3, FHA, FMEA und FTA, sowie auf die Aufgaben und Prozesse im Zusammenhang mit der Lufttüchtigkeit von Flugzeugen. Die Karteikarten sind besonders nützlich für Studierende und Fachleute in der Luftfahrtindustrie, die ein tiefes Verständnis der Wartungsplanung, Systemdesign und Sicherheitsbewertung von Flugzeugen erlangen möchten.

What is an MRBR

Maintenance Review Board Report Document provided by A/C manufacturer, overview of all maintenance points

What is an MPD

Maintenance Planning Document Based on MRBR; tells exactly how to maintenance

What is an AMP and what content does it have?

Airline Aircraft Maintenance Programm 1. Introduction 2. Summary of Changes / cross references to MRBR, MPD, AD, etc. 3. Maintenance Program Tasks (below example) 4. Components and Life Limits 5. Reliability Program

What is an RP and what purpose does it have?

Reliability Program Ensures that AMP is effective and periodicity is adequate.

Why can a perfect system only be built on paper?

in the real world, an engineer may be limited by technology, economics, ability, skill, network

What is ment by saying that the entropy increases with time?

Some components will deteroriate or even lack of use. Perfection level sinks with time.

Explain preventive Maintenance

regularly Maintenance to restore the system and bring it back to a solid perfection level with less entropy. = scheduled maintenance

Which qualities does a component need, so that preventive Maintenance is useful?

Only components with definite life time limits and/or wear out periods will benefit from scheduled maintenance!

How can unscheduled maintenance be preventet? (in-service interruptions)

1. Redundant Systems 2. Line Replaceable Unit (quick replacement, failed part can be repaired later) 3. Minimum Equipment List

What are the three primary maintenance processes in the Process-Oriented Maintenance?

1) Hard Time (Components with definite limits) 2) On-Condition (Components be regularly checked to determine remaining seviceability) 3) Condition Monitoring (monitoring of failure rates, removal rates to facilitate maintenance planning)

To which Maintenancce Steering Group (MSG) belongs the process-oriented approach?

MSG-1, MSG-2 (Bottom-Up) "components are the most likely causes of equipment malfunction"

Explain the Task Oriented Maintenance (MSG-3)

Top-Down Approach which asks: how does a particular failure affects the operation of the aircraft?

What are the three task-categories developed by MSG-3?

Aircraft Systems/Powerplant Tasks Aircraft Structural Tasks Aircraft Zonal Tasks

Decision made through MSG-3; Aircraft Systems/Powerplant Tasks

Lubrication Servicing Inspection Functional Check Operational Check Visual Check Restoration Discard

3 subdivision of Structural Tasks

1) Environmental deterioration 2) Accidental Damage 3) Fatiuge Damage

Explain Aircraft Zonal Tasks

Different zones are built over all systems (overlapping them), to pay enough attention to every system

Who is in the Industry Steering Committee?

Representives of the Airline, manufacturers, Regulatory Authority

What does the Industry Steering Committee do?

establish policy, set goals for scheduled maintenance, prepare final recommendations, direct the activities of the working groups

What do the working groups do?

Deliver written technica data to the ISC.

What is the MMEL?

Master Minimum Equipment ListFrom the manufacturer about a hole Aircraft fleet (A320, A330, A340)

Difference between acitve and latent failure?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

Active = produces immediate effect Latent= produces no immediat effect

Difference between acitve and passive failure?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

Active= will produce large input in the system (erroneous function of the servovelve) Passive= is observable but wont have an input to the system (reduction of hydraulic flow in the actuator)

Two types of random variable?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

discrete: result of a game (win/draw/loss) continous: hours of operation

Probability that something will for sure happen?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

Probability that something will for sure never happen?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

What is safety?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

State in which risk is acceptable

Definition of Hazard?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

potential for harm or disposition of something to cause detriment

System safety is:

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

the implementation of an aircraft design in which the seriousness and the likelihood of occurence of potential harms for passengers and general public is acceptable

In which document are all safety processes regulated?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

1309

Top-Down Analysis

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

high level functional description of the system, failures to each item

Purpose of a Bottom-Up Analysis?

How does a failure condition affect the higher system level?

When should a safety process be done?

It should guide the development process

23.1309 a)

Prevention or mitigation of HAZARDS

23.1309 b)

SAFETY ASSESSMENT, design of each item has to be set in relationship with all other components to have an acceptable risk

explain FHA

Functional Hazard Assessment Focus on Functions not equipment

purpose of the FHA

To identify all failure conditions and describe them in functional and operational terms

When is a FHA done?

Very early in the development process, updated when new failure conditions occur.

Definition of FAULT?

Manifestation in a system or equipment that may lead to a Failure.

Definition of FAILURE?

Event that the affected function can no longer operate as intended.

Definition of FAILURE CONDITION?

Condition which affects the aircraft or the occupants
