Chap 12 Flashcards
What is required for the continuing airworthiness of an aircraft?
Maintenance recording and certification is required to provide a level of assurance for the continuing airworthiness of an Aircraft and/or associated product, parts and appliances.
What are the three key stages for certifying maintenance documentation?
3 key stages:
-1st Signature by the Tradesman/operator,
-2nd Signature by the Supervisor, and
-3rd Signature by the Co-ordinator.
What implications arise from carrying out work on the wrong aircraft?
Carrying out work on the wrong aircraft can compromise flight safety, affect tool control, and waste valuable maintenance time.
What must be assessed before starting maintenance tasks on an aircraft?
The type of task must be assessed, which may require moving the aircraft into a suitable hangar with a flat concrete floor and adequate space for free movement of support equipment and personnel.
What should be consulted before any maintenance is carried out?
The aircraft Technical information and Hazard and Maintenance Notes.
What safety implications can arise from other work in progress?
safety implications, such as
-flight control movements that could cause serious injury if technicians are working in close proximity to moving controls.
What are the hazards of electromagnetic radiation?
Radio or radar checks in progress may be hazardous to other technicians working in the vicinity.
What should technicians do regarding hidden hazards?
Liaise with Supervisor/s of other trades if required.
How can technicians ensure electrical systems are safe?
Check that the aircraft switches are OFF before commencing work.
What is a hazard when working with hydraulic systems?
Normal operating or residual system pressure when removing components may cause control linkages and/or surfaces to move without warning.
What happens if pressure is applied to a hydraulic system with a component removed?
It will result in major fluid loss and possible hazard to personnel.
What should technicians know about accumulators?
Accumulators may be pressurised, e.g., rotor and parking braking systems.
What is a risk when operating flying control systems?
Operation with components removed or work in progress could result in serious damage and/or injury to personnel.
What should be ensured regarding flying controls?
Ensure flying controls are both connected and free to operate or have applicable warning signs displayed and control gags/locks fitted.
What is the risk associated with open fuel tanks or pipelines?
They are a serious fire and explosive risk, especially when applying electrical power to the aircraft.
What should be ensured before applying electrical power to the aircraft?
Ensure no open fuel tanks or pipelines if the task requires application of electrical power.
What should technicians be aware of regarding armament systems?
They should be aware of aircraft armed conditions and hazards associated with any maintenance to be carried out.
What warning signs should technicians display?
Appropriate warning signs include:
- Apply No Electrical Power.
- Apply No Hydraulic Power.
- Control Functional in Progress.
Where can warning signs be displayed?
Signs can be displayed outside or inside the aircraft, including the flight deck.
What should be done to ensure warning signs are not forgotten?
An entry is made on the aircraft documentation for fitting the signs and an open entry for their removal.
What is the responsibility of the technician before maintenance?
Ensure that the aircraft is in a ‘Safe for Maintenance’ condition.
What should a technician do if unsure about safety?
Consult their Supervisor.
What should the Supervisor’s task brief include?
Confirmation of ‘Aircraft Safe for Maintenance’.
