Microbial Contamination in Aviation Fuel and Aircraft Fuel Systems     


I.D.# C0728Printable Description
Duration: 1 Day

Microbial contamination in aviation fuel creates biomats that clog filters and scavenge systems, coat fuel quality indicator systems (FQIS) probes, and lead to structural corrosion, impacting the operational and economical aspects of turbine powered fixed wing and rotary wing aircraft. From inaccurate fuel level readings to aborted take-offs and air interrupts, microorganisms can wreak havoc on the entire aircraft and the system operations. Attendees will learn how microorganisms enter and survive in the fuel distribution and storage network, and how a routine surveillance program can manage risk and mitigate lost profits. Students will have the opportunity to experience hands-on techniques to detect and remediate contamination in aviation fuel systems.

Learning Objectives
By attending this seminar, you will be able to:

  • Describe the impact of microorganisms on aircraft fuel systems
  • Explain how microorganisms survive in an aviation fuel environment
  • Determine how microorganisms enter the fuel storage and distribution system
  • Detect and remediate microbially contaminated fuel systems
  • Improve the overall operational reliability of aircraft and reduce maintenance costs

Who Should Attend
This seminar is appropriate for aircraft fuel systems design engineers, aviation fuel quality managers in manufacturing, storage and distribution facilities, aircraft fuel quality managers, and aircraft maintenance technicians.

Attendees should have a basic understanding of fuels and fuel systems.
