7.3.15 Lubrication Equipment Flashcards
What does ‘servicing’ of aircraft refer to?
The term ‘servicing’ is used to replenish and check the aircraft’s systems to maintain the aircraft in an airworthiness operational condition.
Where can information about servicing operations for a specific aircraft be found?
In accordance with ATA Specification 100, information relating to the servicing operations for a specific aircraft is found in Chapter 12 of the Aircraft Maintenance Manual.
What must be adhered to during aircraft servicing?
Always adhere to the following mandatory tasks and safety instructions.
What is required for ground equipment used in aircraft servicing?
The ground equipment used for aircraft servicing has to be kept clean and maintained in accordance with a schedule recommended by the equipment manufacturer.
What must be done with hoses from liquid and gas servicing trolleys when not in use?
Hoses from all liquid and gas servicing trolleys have to be blanked when not in use, and their cleanliness and serviceability have to be checked before they are used on an aircraft.
What type of fire extinguishers must be accessible during aircraft servicing?
Fire extinguishers suitable for fuel and electrical fires must always be readily accessible when an aircraft is being serviced and must be subject to regular inspection.
Why is lubrication critical in aircraft operation?
Lubrication is critical to the safe operation of any aircraft and its systems.
How is engine oil replenished in modern aircraft?
Replenishment of engine oil, hydraulic oil, and other systems containing a fluid is achieved by the use of hand-held equipment or servicing carts that are specially designed for the task.
What must be ensured when replenishing lubricants in aircraft?
Care has to be taken to ensure that only the approved fluids are used and that no foreign matter is allowed to enter the system.
What are the types of lubricants used on aircraft?
The lubricants used on aircraft can be broken down to: Greases, Oils, Speciality Lubricants.
What areas broadly use lubricants in aircraft?
Areas where the lubricants are used can broadly be broken down to: Airframe systems (Hydraulic, Flight Controls, Landing Gear etc.) and Engine & Gearbox systems.
What must be done to the equipment used for lubrication?
The equipment used for lubrication/greasing has to be kept clean and must only be filled with clean/new lubricant.
What personal protective equipment (PPE) must be worn when applying lubricants?
PPE must be worn which could range from protective gloves and eye protection to full face masks and body coverings.
What should be reviewed before applying lubricants?
Always refer to the relevant maintenance manual instructions, company procedures, COSHH, HSE and MSDS.
What is a Material Safety Data Sheet (MSDS)?
Each lubricant will have an associated Material Safety Data Sheet (MSDS) associated with it and this should be easily accessible to the user.
How should greases and oils be stored?
All greases and oils must be kept in a dedicated fire proof cabinet and in a clean condition.
What is the method of application for general servicing oils?
General servicing oils will be used for many areas where a simple ‘drop’ of oil is sufficient, applied through a hand-held container with a hand operated pump system fitted, an oil can.
What is required to apply speciality lubricants by aerosol?
The can must be shaken well until the ‘pea’ can be heard moving around the can with no restriction before use.
What types of hydraulic oils are commonly used on aircraft?
Hydraulic oil on aircraft are commonly either a mineral based oil or an ester phosphate based oil.
What is a can opener used for in hydraulic oil replenishment?
A can opener is required to open a can when replenishing a system by a ‘direct fill method’.
What is a hand pump used for in hydraulic systems?
A hand pump is used to pump the fluid into a system via a pressure connection.
