What are major defects?

A

Defects that are found on an aircraft as a result of an Airworthiness Directive Inspection or defects that are found by a pilot or engineer that are considered to adversely affect the airworthiness or safety of the aircraft and need correction before further flight.”

  • Unscheduled Engine Shut Down
  • Fuel System Malfunction
  • Significant contamination or leakage of fuel, oil or other fluids
  • Use of incorrect Fuel
  • Landing Gear Failures
  • Brake System Defects
  • Malfunction, stiffness or slackness or limited range of control movement
  • Significant failure of Instruments,Electrical, Hydraulic, Radio or Nav Systems or Emergency Equipment
  • Uncontrollable Cabin Pressure
  • Cracks, Major Damage or Corrosion in the primary structure
  • Any malfunction to a system which has safety implications
  • Any Defect found as a result of an Airworthiness Directive

Q

What are minor defects?

A

Defects which are considered Minor and which do not affect Safety are often referred to as ‘NAD. Not an airworthiness defect”. Their repair may therefore be deferred provided that a certified Engineer working on the aircraft agrees to the deferral.

Q

What are deferred defects?

A

Deferred Defects are unrectified defects, which are either minor or can be considered to be permissible unserviceabilities. The aircraft may be allowed to fly safely without the defect being repaired

Q

What is the PUA?

A

The PUA allows the aircraft to operate when certain systems or parts of systems which are not covered by an MEL/CDL statement are inoperative. The approval must be granted by CASA or its representative

Q

What is an AD?

A

Airworthiness Directive.
Notification to owners and operators of certified aircraft that a known safety deficiency with a particular model of aircraft, engine, avionics or other system exists and must be corrected.
• that the aircraft may have an unsafe condition, or
• that the aircraft may not be in conformity with its basis of certification or of other conditions that affect the aircraft’s airworthiness, or
• that there are mandatory actions that must be carried out to ensure continued safe operation, or
• that, in some urgent cases, the aircraft must not be flown until a corrective action plan is designed and carried out.
