Maintenance Protocols Flashcards

What is the main reason scheduled preventive maintenance (PM) is done on GSE?

Answer: To find and fix wear before it causes breakdowns or aircraft damage

Preventive maintenance replaces worn parts on a schedule to reduce failures and the risk of aircraft damage.

GSE preventive maintenance is most commonly scheduled based on what?

Answer: Engine hours or calendar intervals

Most GSE PM programs use hour meters or set calendar intervals, following manufacturer recommendations.

A ramp agent notices that the rubber bumper pads on a belt loader's front end are torn away. Why does this matter?

Answer: The bumpers protect the aircraft fuselage from contact damage

Bumper pads cushion contact with the aircraft, so missing pads raise the risk of skin damage and must be reported.

Which of these is a sign that a pushback tractor's tow bar should be removed from service?

Answer: The shear pin is damaged or the wrong type is installed

Shear pins are designed to break to protect the nose gear, so a damaged or wrong pin can cause aircraft damage.

Before using a deicing truck, what should the operator check on the boom and nozzle system?

Answer: For fluid leaks, hose damage and correct boom function

Leaking hoses or faulty booms can spray fluid incorrectly or strike the aircraft, so they are checked before each use.

A GSE unit has a missing fire extinguisher or one with an expired inspection tag. What should happen?

Answer: Report it so the extinguisher is replaced or inspected before use

Fire extinguishers on GSE must be present, charged, and inspected, so missing or expired units must be fixed.

Which practice helps prevent FOD from GSE maintenance work on the ramp?

Answer: Accounting for all tools and parts and cleaning the area after work

Tool control and cleanup keep loose items from being sucked into engines or damaging tires.
