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

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

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

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

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

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

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

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

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
