How long does an aircraft have to be tested if has previously been used
150 hours
What requirements does environmental protection protect?
Noise requirements, Emission requirements
What do type certificate and restricted include what

Certification basis requirements
Environmental protection requirements
Noise data sheets
Records of emissions
What changes would require a new certificate?
Significant changes such as: power, thrust and mass
Are you allowed to transfer type certifications
Yes, the transferee has to be able to demonstrate the ability to undertake obligations of previous obligations
How long does a type certificate last
It lasts forever, as long as it mains in compliance with annex i - part 21.

What is a restricted type certification?
Aircraft doesn’t meet all requirements but is deemed safe to fly
Engine or propeller must have full type certificate
What does a type design consist of?

Where is a type certificate data sheet stored?
On EASA website
What are instructions for continuing airworthiness
The type certificate holder issues one set if continued airworthiness instructions on how to keep the aircraft airworthy.
This can be delayed but needed when the aircraft reaches relevant hours/cycles.
Classification of changes in type design
Minor doesn’t effect mass, balance, structural strength, noise or other characteristics of airworthiness.
All other changes are major changes
How would minor changes be approved?
By the agency
Or by an appropriate approved design organisation under a procedure agreed with the agency
How would major changes be approved?
Submit required data
Show how the changed product will comply with CS’s
Make a declaration with applicable type certification
What is a supplemental type certification (STC)?
-issued by NAA on behalf of EASA
-Major changes to design by other than the type certificate holder
-Organisations making the change must have design organisation approval
What must supplemental type certification provide to the 145
Manuals
Who can apply for a certificate of airworthiness?
A person or organisation who has a registered aircraft
What is a standard changes
Changes to the type design to aeroplanes and rotorcraft
What language must be used in manuals , placards and instrument markings?
