The type certificate holder


What are airworthiness codes also known as ?

Certification Specifications


What should be included in the application of a type certificate?

- A three-view directional drawing
- Preliminary data
- Operating characteristics
- Limitations


Why can some type certifications require special conditions from EASA?

- The product has an unusual design
- The intended use of the product is unconventional
- Unsafe conditions could develop


How long is a type certificate APPLICATION for a small aircraft effective for?

3 years (unless at time of application is shown that it requires longer)


When would it be deemed necessary to propose a change to the type certificate of a product?

When any agency finds a;
- Change in design
- Change in power
- Change in mass
- Change in thrust


What does DOA stand for?

Design Organisation Approval


Who is eligible to apply for a Certificate of Airworthiness (C of A)

Any person or organisation that the aircraft is registered to.


What language must the C of A be printed in?

One or more of the official languages of the EU


How long is the C of A valid for?

Remains valid indefinitely, as long as:

- it remains on the same register
- the type certificate remains valid
- type certificate has not being surrendered or revoked
- requires validating with the Airworthiness Review Certificate (ARC)


What is the purpose of a C of A

It is the internationally recognised document certifying an aircrafts sustainability to enter service.

E.g. Development of a new aircraft


If flight conditions are not approved at the time of application of a permit to fly, who should the approval be sent to?

- Agency = if the approval of flight conditions is related to the safety of design

- Competent Authority = if the approval of flight conditions is NOT related to the safety of design


If an EASA permit to fly is issued by an organisation other than the competent authority, what must be done?

Copies of the permits must be sent to the competent authority as soon as possible but no later than 3 days
