A dealer technician is in the field with a stalled combine harvester. It is the middle of harvest season. He calls the OEM support desk, asks for the service procedure for a specific hydraulic failure, and is told to check the printed manual. That manual is three revisions behind. The part number has changed twice.
The pre-delivery inspection is one of the most consequential events in the dealer-customer relationship. It is the last quality gate before a vehicle or machine leaves the dealership and enters the customer's hands. If the PDI is thorough, defects are caught, resolved, and documented before delivery. If it is rushed or incomplete, defects follow the customer home and become warranty claims, repeat visits, and CSI problems.
In an industry where a single component failure can have catastrophic consequences, aerospace Original Equipment Manufacturers (OEMs) operate under some of the most demanding compliance frameworks in the world. From FAA regulations to quality standards, the pressure to document, verify, and audit every stage of production is relentless.
Warranty costs are quietly eroding OEM margins at scale. For many manufacturers, warranty spend represents 2-5% of total revenue, a figure that compounds annually as product complexity rises and claim volumes grow. Yet the deeper problem is not the claims themselves; it is how they are managed.
A single incorrect part order creates a ripple effect across the entire service operation. The technician pauses work, the service bay remains occupied, repair timelines slip, and customer satisfaction drops. Beyond the cost of the part itself, dealerships lose billable hours and risk damaging long-term customer trust.
Wrong parts orders are one of the most persistently expensive problems in automotive parts distribution, and one of the least discussed at a serious level. Most organizations know they have the problem. Fewer have quantified it rigorously. And fewer still have taken systematic steps to address the root causes rather than managing the symptoms.
The aftermarket runs on a simple expectation: when a machine goes down, the correct spare part should be available where it’s needed, without delay. In reality, this breaks down far more often than OEMs would like to admit. Incorrect parts identification and poorly aligned stocking decisions continue to drive returns, service delays, and avoidable warranty costs.
