DEVELOPING AGE EXPLORATION TASKS


3/16

This module will provide information

on developing Age Exploration tasks.

IntroductionModule Objective:



4/16

AE Task Development

Systematic approach for collecting andanalyzing data to:

Refine RCM analysis assumptions and data Optimize PM tasks

Age Exploration should be targeted tospecific failure modes

Description:



5/16

AE Task Development

Impact On Maintenance:

AE is not part of scheduled PM, but does impactthe maintenance effort

Impact may be felt in increased: burden/disruption to the maintenance

workforce

equipment downtime

demand on maintenance resources



6/16

AE Task Development

Impact On Maintenance:

Because of these potential impacts, AE tasksshould be designed with as little disruption to themaintenance program as possible.

AccomplishAE in concert with

scheduled PM, if possible

Use existing: Tools

Manpower Skills

Eliminate:

Peculiar support equipment

Specialized technical training



7/16

AE Task Development Safety Consequences:

Collecting failure data for safety failure modesmust be performed in a way that does not allowfunctional failure to occur.

Laboratory environment Analytical Methods Controlled operation


8/16

AE Task Development

Using AE to establish life limits . . .

Test a sample of items to failure in laboratory The test would be an AE task

Safety Consequences:



9/16

AE Task Development Safety Consequences:

Using AE to monitor degradation . . . Set potential and functional failure limits

Note: Potential failure limit must be conservativeenough to prevent functional failures fromoccurring

Collect in-service degradation data Remove item when potential failure condition is

discovered Send to laboratory to continue data collection in

a safe environment



10/16

AE Task DevelopmentNon-Safety Consequences:

Using AE to collect data for non-safety issues . . . Loss may have impact on mission/economics

Data can be collected while equipment is inoperational environment

Note: Items can be allowed to fail in-servicesince safety not affected as long as impact

on mission or economics is acceptable Laboratory testing usually not necessary AE task may be just monitoring existing data

collection systems



11/16

Definitions:

Task Description: Thorough description of task,directed toward specific Failure Mode

Task Interval: Frequency that task is performed Initial Inspection: Time which first AE task is

performed on an item

13/16

Sample % : Sample quantity divided by number ofitems in total population

Task Duration: Length of time, e.g., cycles,operating hours, task will be performed on eachitem in sample population

Man-hours: Average man-hours required tocomplete one AE task

Definitions: AE Task Elements



14/16

Material Cost: Average cost of materials requiredto perform one AE task. Does not include repaircost.
