Engineering analysis activity is cover under which maintenance?
Preventive maintenance
Predictive maintenance
Breakdown maintenance
None of above
Breakdown maintenance
Quick Summary: Engineering analysis, often referred to as Root Cause Analysis (RCA), is a post-failure activity primarily associated with breakdown maintenance. It involves examining failed components to identify the cause of failure to prevent recurrence, distinguishing it from routine or predictive inspections.

MTTR=Number of RepairsTotal Maintenance Time — Represents the mean time to repair during breakdown maintenance.
When a machine fails unexpectedly, the breakdown maintenance workflow initiates. The 'Engineering Analysis' phase involves disassembling the equipment, testing failed parts for stress, corrosion, or fatigue, and reviewing operational logs. This data is then used to implement corrective actions during the repair process.
Breakdown maintenance is also known as reactive or corrective maintenance.
Engineering analysis helps in moving from 'Corrective' to 'Preventive' strategies.
It is usually performed only after the equipment has ceased functioning effectively.
Low initial setup cost
No requirement for expensive diagnostic sensors
High downtime risks
Unpredictable maintenance costs
Non-critical low-cost equipment
Systems with high redundancy where failure does not halt operations
Preventive maintenance involves scheduled tasks based on time or usage intervals.
Predictive maintenance uses condition monitoring (Vibration,Thermography) to predict failure before it occurs.
Engineering analysis is distinct because it is retrospective, focused on the 'Why' after the 'What' has already happened.
C is correct — Engineering analysis is a diagnostic procedure performed after a breakdown to determine the root cause of the failure.
In competitive exams, always link 'Engineering Analysis' or 'Failure Analysis' with 'Corrective/Breakdown' strategies, while 'Condition Monitoring' should be linked with 'Predictive' strategies.
