Liburdi's Component Life Extension — Savings for the Operator:

Conventional repairs carried out by others are limited to weld repairs and strip/recoat. The parts are then typically retired after 50,000 - 70,000 hours of service per OEM convention.

Liburdi's Advanced Repairs are designed and proven to extend the reliable service life to 100,000+ hours.

This can amount to a maintenance savings of $400,000 - $800,000 at the time of engine overhaul.

Savings = the difference between the cost of new parts and the cost of the Advanced Repairs.
