SHT-21 Certification

Certification of aircraft, engine, propeller and related parts that are designed and manufactured in our country is done by the Aircraft and Parts Certification Coordinating Section.

Also, approval of design and manufacturing organisation, publishing of type/supplemental type certification, approvals for parts and appliances, certification acceptance including  aircraft and parts that are designed and manufactured in foreign countries which they will register in our country, as well as the certification processes that are carried out in line with the production of Amateur/Home Built Aircrafts are all under the coordination duties.

The conformity to international standards for aircraft and parts that have been designed and manufactured in our country is implemented using national and international conformity assessment legislation that has been officially published.

In addition to these duties, the Aircraft and Parts Certification Coordinating Section also conducts certification panel meetings, attends test-validity activities, audit organizations and manage bilateral relations for aviation safety.

The Aircraft and Parts Certification Coordinating Section uses the following legislation.

 


 

Permit to Fly Process

A Permit to Fly is issued when a certificate of airworthiness is temporarily invalid or when compliance with those requirements has not yet been shown, but the aircraft is nevertheless capable of performing a safe flight as outlined in SHT-21.
The cases for which a permit to fly need to be issued are the following:
-          Research and development,
-          Showing compliance with regulations or certification specifications
-          Design or production organisations crew trainings,
-          Production flight testing of new production aircraft,
-          Flying aircraft under production between production facilities,

-          Flying the aircraft for Authority acceptance,
-          Market survey, including customer’s crew training,
-          Exhibition or air show,
-          Flying the aircraft to a location where maintenance or airworthiness review are to be performed, or to a place of storage,
-          Flying an aircraft at a weight in excess of its maximum certificated take off weight for flight beyond the normal range over water, or over land areas where adequate landing facilities or appropriate fuel is not available
-          Record breaking, air racing or similar competition,
-          Flying aircraft meeting the applicable airworthiness requirements before conformity to the environmental requirements has been found,
-          For non-commercial flying activity on individual non-complex aircraft or types for which a certificate of airworthiness or restricted certificate of airworthiness is not appropriate,

  • Approved TC and TCDS.
  • 3D Drawings, Type Definition document or equivalent document
  • Certification Compliance Checklist
  • Compliance to special conditions including novel or unusual design features
  • Engine emission information in the context of Annex 16 issued by ICAO

  • Web Access Authorization for maintenance and operation documents (MPD, SB, IPC, MMEL, etc.)
  • Operating and installation manuals (for engine and propeller)
  • Familiarization Training for  DGCA personnel.(At least 20 trainees)

 

Familiarization Training should be comprised of;

  • Overview of fuselage, engine, electical and avionic systems,
  • Working principles of system components,
  • Safety issues,
  • Maintenance applications, test tools, etc.
  • Other subjects determined by the applicant.

 

After the reviewing of the documents and demonstrations, if DGCA finds it acceptable, Type Certificate Acceptance Document is issued to applicant and its own certifying authority by DGCA.

The procedure given above can be amended if the Bilateral Agreement allows different procedure.

 

Accepted type certificates by DGCA are given below in the framework of the prescribed procedure.

Bilateral Aviation Safety Agreements & Working Arrangements (BASA & WA)

The Directorate General of Civil Aviation (DGCA) cooperates with the foreign civil aviation authorities in order to increase the aviation safety, share experiences, and reciprocal acceptance of the products/certificates. In addition, the aforementioned agreements prevent the same transactions twice and also increase the reliability of the civil aviation of Turkey in the international arena. In this context, the agreements made by our General Directorate are given below:
 
Working Arrangements:
1- European Aviation Safety Agency (EASA)
2- The Federal Air Transport Agency (Russian Federation-FATA)

Memorandum of Understanding:
1- The National Civil Aviation Agency of Brasil (ANAC)
2- Korea Office of Civil Aviation (KOCA)
3- State Aviation Administration of Ukraine (SAAU)

Bilateral Aviation Safety Agreements:
1- The negotiations with the American Federal Aviation Agency (FAA) are ongoing.
2- The negotiations with the Transport Canada Civil Aviation (TCCA) are ongoing.
3- The negotiations with the Civil Aviation Administration of China (CAAC) are ongoing.

Airworthiness Directives - ADs

Airworthiness Directives (ADs) are instructions to the type certificate holder and/or aircraft operators when aircraft, engines, avionics or another systems are in unsafe condition.
 
For each aircraft with a type certificate, issued airworthiness directives by the relevant civil aviation authority must be followed and implemented on time. Otherwise, flight of the aircraft is not allowed.
 
Besides, except for the foreign civil aviation authorities DGCA may issue its own airworthiness directives.
