The Situation

After a mechanical failure, ILC identified the cause of damage, assessed the extent of damage, and verified the repair costs associated with the horizontal grinder’s restoration.

Establishing Cause of Loss 

The investigation determined that repeated mechanical failures were the direct result of improper repairs, inadequate maintenance practices, and continued misuse of the equipment. Replacement parts were installed without addressing underlying issues, allowing damage to compound over time and ultimately leading to catastrophic failure.

Preventing Continued Cost Escalation and Operational Loss

By identifying that nearly $100,000 in repairs failed to correct the root causes of failure, the analysis demonstrated that ongoing investment in the grinder was ineffective. Continued operation under improper conditions accelerated deterioration and directly contributed to the unit becoming inoperable.

The Results

Root Cause Identified and Corrective Path Established

ILC determined that the grinder failures were caused by prolonged operation with severe vibration resulting from an improperly repaired main rotor operating out of dynamic balance. The failure was attributed to improper repairs, inadequate and untimely maintenance, and user misuse which provided a clear, defensible cause of loss and a defined corrective repair scope aligned with industry-accepted practices.

Avoided Unnecessary Replacement and Controlled Costs

ILC concluded that full machine replacement was not required to restore proper operation. By identifying and recommending essential repairs totaling $125,967, ILC helped avoid unnecessary replacement costs while addressing damage caused by prolonged operation without OEM-supported or industry-standard repairs.
