EASA Part 66 Module 15.9 : Lubrication and Fuel

  1. 1. 15.9 LUBRICATION AND FUEL http://part66.blogspot.com/
  2. 2. SOURCE OF OIL • Synthetic : – Fatty acid and esters (alcohol and asid) – Purple color • Vegetable : – From castor oil, olive oil – Yellow color • Mineral : – From crude oil – Red color
  3. 3. LUBRICATION • Function : – Reduce friction – Reduce temperature – Clean the system • Film Lubrication : – Oil is lubricate between 2 contact surface • Boundry Lubrication : – Loss of oil between 2 contact surface
  4. 4. OIL PROPERTY • Ability to cling to the bearing surface (oiliness) • Possesses stable viscosity (low) • High heat capacity • Not causing damage to contact material • Not flamable • Chemically stable • Safe to handle
  5. 5. OIL ADDITIVE • Extreme pressure (heavy operation) • Anti-corrosion additive • Detergent additive (hold debris) • Inhibitor (slow down oxidation product)
  6. 6. OIL CONTAMINATION • Can be detect on the filter and magnetic plug • Take example and analys • Drain oil if contaminate • Clean or replace filter • Flush the system with clean lubricating oil • Refill the system
  7. 7. FUEL SPECIFICATION • Fuel should : – Pumpable and flow easily – Efficient combustion – High caloric value – Minimal harmful effect – Minimal corrosive effect – Provide edequate lubrication for moving part – Reduce fire hazard to minimum
  8. 8. TYPE OF FUEL • Kerosene fuel (AVTUR) – For turbine engine – Low temperature fuel – Eg : Jet A and Jet A-1 • Petrol fuel (AVGAS) – For piston engine – Eg : Avgas100
  9. 9. ADDITIVE • Anti-Oxidants (prevent deposit formation) • Static Dissipator (reduce static generated) • Corrosin Inhabitors • Fuel System Icing Inhibitors • Metal De-activators (suppress catalytic effect) • Biocide (reduce microbiological growth in fuel)
  10. 10. FUEL CONTAMINATION • Microbiological Contamination – Effect inaccurate fuel tank content, blockage and corrosion of alluminium alloy – Prevent by fungicidal additive to fuel • Water contamination – Test by hydrokit (pink/red – presence of water) – Water settles at bottom of tank due to density
  11. 11. SAFETY REFUELING/DEFUELING • Avoid all unnecessary contact and use protective equipment • Never wear fuel soaked clothing • Clean up spilled product immediately • Avoid breathing fuel vapor (ventilation) • Have fire fighting equipment • Ensure both aircraft and bowser earthing • No radio or radar equipment operated
