What is the role of a CDI in fuel sample inspections?

The role of a CDI, or Collateral Duty Inspector, in fuel sample inspections is critical for maintaining the safety and integrity of aircraft operations. Their primary responsibility during these inspections is to ensure that the fuel sample is clear and bright. This means that the sample is free of contaminants, such as water or particulate matter, which could adversely affect aircraft performance and safety.

A clear and bright fuel sample indicates that the fuel meets the specified quality standards necessary for safe operation. Contaminants in the fuel can lead to engine malfunctions, performance issues, or even catastrophic failures during flight. Therefore, the CDI’s thorough inspection of the fuel samples helps to ensure that any adverse conditions are identified before they affect the aircraft.

While refilling the fuel tank, recording flight hours, and initiating maintenance work are important tasks within aviation operations, they are not directly related to the specific responsibilities of a CDI regarding fuel quality assurance. The focus in this context is solely on the critical evaluation of fuel quality through the inspection process.
