How often must inspections be completed on aircraft used for external load operations?

Inspections on aircraft used for external load operations are governed by FAA regulations, which specify that these aircraft must undergo inspections at intervals outlined in the manufacturer's guidance or every 12 months, whichever is more frequent. This frequency ensures that the aircraft remain airworthy and safe for operation, specifically considering the additional stresses imposed during external load operations.

These inspections are crucial because external load operations involve unique risks, including the weight and movement of cargo that can affect the aircraft's structural integrity and performance. Consequently, regular inspections serve to identify any potential issues early on and maintain high safety standards.

The manufacturer's guidance is significant as it provides tailored recommendations based on the specific design and operational context of the aircraft, reflecting the best practices for maintaining the aircraft's safety and performance. This dual approach—following the manufacturer's recommendations or adhering to the minimum 12-month interval—ensures that operators are compliant with regulatory requirements while also considering best engineering practices.
