Maintenance-Induced Failure

A maintenance-induced failure is an equipment problem caused or accelerated by incorrect, incomplete, excessive, or poorly controlled maintenance activity.

What this term means in maintenance

A maintenance-induced failure is an equipment problem caused or accelerated by incorrect, incomplete, excessive, or poorly controlled maintenance activity.

Common causes

Maintenance-induced failures may result from:

Wrong part
Incorrect assembly
Contamination
Over-lubrication
Under-lubrication
Misalignment
Loose fasteners
Incorrect settings
Damage during access
Inadequate testing

Practical example

A bearing fails soon after replacement because contamination entered during installation.

Prevention

Controls include job plans, precision standards, clean work, competency, verification, checklists, and post-maintenance testing.

Investigation

Review the timing of failure, work performed, parts, measurements, procedures, and evidence.

Common mistake

Assuming every post-maintenance failure is random prevents learning from work-quality problems.

Precision Maintenance

Precision maintenance is the disciplined use of accurate installation, assembly, alignment, balance, torque, lubrication, cleanliness, and measurement standards.

Maintenance Rework

Maintenance rework is additional maintenance required because earlier work was incomplete, incorrect, ineffective, or did not meet acceptance requirements.

Root Cause Analysis

Root cause analysis is a structured investigation used to identify the underlying conditions that allowed a failure or problem to occur and determine actions that reduce recurrence.
