Introduction
In the high-stakes world of base maintenance, the most dangerous defect is the one you didn't see coming. While the scheduled work order defines what needs to be done, the Incoming Inspection reveals what must be done to ensure the continued airworthiness of the aircraft.
We view the incoming inspection not as a bureaucratic hurdle, but as a critical visual preliminary assessment. It is the "handshake" between the operator and the maintenance facility—a moment to document the aircraft's baseline condition before a single panel is removed. Failing to capture existing damage early can lead to safety risks, project delays, and commercial disputes.
What is an Incoming Inspection?
An incoming inspection is a comprehensive visual sweep of the aircraft’s exterior and interior. The goal is to identify abnormalities in the skin, paint, and interior trim, as well as any existing damage.
This process is performed at "arm's length" to ensure no detail is missed, covering everything from the nose radome to the static dischargers on the tail. It ensures that the maintenance team starts with a clear, annotated roadmap of the aircraft’s current state.
The Checklist: A Systematic Approach to Safety
A "walk around" isn't enough; the inspection must be systematic. Using a standardized checklist ensures that high-pressure systems and structural components are verified immediately upon arrival. Key areas include:
- Structural Integrity: Checking the fuselage and wing skin for deterioration, distortion, or insecure attachment of fittings.
- Powerplant Pre-Check: A visual search for oil, fuel, or hydraulic leaks in the engine nacelles and bypass ducts.
- Landing Gear Health: Inspecting shock struts, linkages, and tires for wear, flat spots, or hydraulic leakage.
- Data Accuracy: Verifying that the 'Dent and Buckle' chart matches the actual physical condition of the airframe.
Protecting the Asset and the Engineer
Incoming inspections aren't just about the metal; they are about the interior environment. Our procedures mandate that if cabin or galley work is expected, a detailed report including photos must be generated. If no work is required, the area is inspected for cleanliness and then closed off to prevent accidental damage during the maintenance bridge.
By protecting the floor areas, galley, and entrance steps, we ensure that the aircraft is returned to the client in the same—or better—condition than it arrived.
Common Findings During Inspection
Even on well-maintained fleets, "hidden" defects often surface during the incoming phase. Our engineers are trained to look for:
Conclusion: Setting the Standard
A rigorous incoming inspection is the hallmark of a professional MRO. It provides the "Work Order" with context and ensures that when an aircraft leaves the facility, every defect—whether it arrived with the plane or was found during the check—has been addressed and signed off by a qualified engineer.
