What could a file mark, corrosion, or scratches in metal cause?
- Stress raiser - increase metal fatigue

Metal fatigue is the loss of original strength and reliability of a metal after a period of service. This may be expressed as the failure of a metal after repeated applications of a cycle of stress
What maintenance program is used to detect faults before major factors?
- Aircraft inspection program
- Operational Maintenance (OM)
Deeper Maintenance (DM).
How does an aircraft’s age affect maintenance?
Additional inspections to managed the structural fatigue of the aircraft:
- Increased maintenance requirements
- Generally unscheduled servicing is likely to occur more
As the age of the aircraft increases, the maintenance increases to match
What are 4 possible outcomes that inspections of an ageing aircraft may produce?
- Revised ageing aircraft policy
- Change in flight parameters of the aircraft (limitations)
- Change in designed role of the aircraft
Change in the configuration of the aircraft.
Which OEM system enables you to quickly identify the location of a component?
Original equipment management
Aircraft reference numbering system
Where is the datum for fuselage stations usually located?
- Station zero
- The forward portion of the fuselage
- To the left is negative, to the right is positive
Which maintenance regime requires a product or part to be periodically inspected or checked against a standard to see whether it can remain in service, rather than being removed and disassembled?
On condition maintenance - scheduled maintenance
What is the broad term used for maintenance performed on an aircraft on an unplanned basis?
Unscheduled maintenance
What is the broad term used for maintenance performed on an aircraft on a planned basis?
Scheduled maintenance
What type of component is an overhaul conducted on?
MMI - maintenance managed item
What are the 4 aircraft servicing categories?
- Operational
- Routine
- Special
- Storage
Which OP serv is conducted on aircrafts between successive operations?
Turn around
Which OP serv brings an aircraft to a state of readiness for operation?
Before flight
Which of the above includes maintenance actions such as removing blanks and safety devices?
Before flight
Which OP serv would be required after the last planned flight of the day?
After flight
Describe a routine servicing
Routine (R) Servicing is a set of preventive tasks that are necessary to preserve an aircraft or aeronautical product’s inherent level of safety and operational reliability
At what maintenance level can an R be conducted?
- OM
- DM
What type of unplanned servicing is carried out after an aircraft operates on a corrosive environment?
Special servicing - not covered in op or routine servicing, pops up due to specific reasons
- Hard landing
- Corrosive environment
- What servicing maintains an aircraft while it is in preservation?
Storage servicing
What is a safety precaution for a pressure system?
- Release system pressure before performing any maintenance on pressurised systems
- Follow manufacturer’s maintenance instructions
- Ensure that correct PPE is worn
Which safety precautions apply for a hydraulic system?
- Ensure that correct PPE is worn (found on SDS)
- Depressurise
- Do not handle hydraulic fluid if you have open cuts etc
- DO NOT search for leaks with a bare hand
- Always read the relevant: Caution, warning, safety notes
- Manufacturers manual
How could you get across to the SDS for a chemical here at ATT?
Chem Alert
When does an SDS need to be reissued?
- 5 years
- When anything is changed within the information (first aid etc)
What are 3 hazards resulting from poor housekeeping?
The basic principles for good housekeeping are:
- Proper equipment and workplace layout
- Correct materials handling and storage
-Waste disposal
- Cleanliness
Hazards include:
- Fire
- Accidents
- Waste
What is the purpose of foreign object control (FOC)?
Definitions:
- FOC - defined as foreign object control
- FOD - defined as foreign object damage
Purpose of FOC is as follow:
- The primary objective of foreign object control is to prevent the ingress of foreign objects into aircraft and aeronautical products
What are some hazards of confined space entry?
- Lack of oxygen / ventilation
- Exposure to toxic chemicals, gas, fumes, vapours
- Restricted access
- Extreme temperatures
- Manual handling hazard
- Fire / explosions
- Excessive noise
- Engulfment by solids, liquids and gases
List the conditions to be met if you (a worker) needed to enter a confined space?
- Valid licence / permit
- Must be trained
- Standby person is required to be in place before entering the confined space, and remain there until the job is complete or the person in the confined space is out
Provide 1 reason PED are restricted in the aviation workplace:
- Security (access / camera)
- Distraction
- Just because it is a rule
Which ADF manual prescribes quality design requirements for aircraft systems and functions?
Relevant aircraft manual / pubs eADRM 7001.054
Which ADF manual contains the ADF approved quality standards and procedures used for the management of maintenance activities?
AFCAMAN
