SERIES ‘A’, PART II
ISSUE I, 7th OCTOBER, 2014 EFFECTIVE: FORTHWITH
F. No. DGCA-27014/2/2025-AED
Subject: Requirements for recognition/ acceptance of Type Certificate,
Restricted Type Certificate and Supplemental Type Certificate issued
by a Contracting State for aeronautical product, viz. aircraft, aircraft
engine and propeller.
1. Introduction:
Rule 49E of ‘the Aircraft Rules 1937’ provides for recognition/ acceptance of Type
Certificate (TC) or Restricted Type Certificate (RTC) issued by a Contracting State. It
empowers the Director General of Civil Aviation (DGCA) to accept the TC/ RTC or any
other similar document in respect of an aeronautical product, i.e. aircraft, engine, and
propeller issued by a contracting state whose airworthiness requirements are at least
equal to the requirements established in accordance with the national regulation
contained in CAR 21.
Similarly, Rule 49G of the Aircraft Rules, 1937 provides for recognition/ acceptance of
Supplemental Type Certificate (STC) in respect of an aeronautical product issued by
a Contracting State. The rule states that the Director General may accept STC issued
by a Contracting State in respect of the aeronautical product.
This CAR is issued under the provisions of Rule 49E, 49G read in conjunction with
Rule 133A of the Aircraft Rules, 1937.
2. Definition:
2.1 Aeronautical product means any civil aircraft, aircraft engine or propeller.
2.2 Airworthiness requirements means the comprehensive and detailed
airworthiness codes established, adopted or accepted by DGCA for the class
of aircraft, engine or propeller under consideration.
2.3 CAA means Civil Aviation Authority of a contracting state.
2.4 Contracting State means any State which is for the time being a party to the
Convention on International Civil Aviation concluded at Chicago on December
7, 1944, and any amendment which may be made thereto under the
provisions of Article 94 thereof.

SERIES A PART II 7th OCTOBER 2014
2.5 Operator means a person, organization or enterprise engaged in or offering
to engage in aircraft operation.
2.6 Satisfactory evidence means a set of documents or activities that DGCA
accepts as sufficient to show compliance with an airworthiness requirement.
2.7 Type Certificate means a document issued by a Contracting State to define
the design of an aircraft, engine or propeller type and to certify that this design
meets the appropriate airworthiness requirements of that State.
3. Applicability:
3.1 ICAO Annex 8 allows each Contracting State to adopt/ accept a
comprehensive and detailed code established by another Contracting State.
Accordingly, DGCA as an ICAO Contracting State has adopted/ accepted the
airworthiness codes of FAA/ EASA.
DGCA shall accept the TC/RTC/STC issued by FAA/ EASA. DGCA shall also
accept the TC/RTC/STC of an aeronautical product, when the airworthiness
codes of the CAA of the State of Design of that aeronautical product are
harmonized with the airworthiness codes issued by FAA/ EASA viz. CS-LSA,
CS 22, CS VLA, CS VLR, CS/ FAR 23, CS/ FAR 25, CS/FAR 27, CS/ FAR
29, CS31HB/FAR-31, CS-E / FAR 33, CS-34/FAR 34, CS-P/ FAR 35 and CS/
FAR 36.
3.2 However, DGCA shall validate the TC/RTC of an aeronautical product in
accordance with CAR Section 6 Series ‘A’ Part I in the following cases:
a) when the airworthiness codes of the CAA of a Contracting State are not
harmonized with that of FAA/ EASA; or
b) an Indian organization intends to manufacture an aeronautical product in
India under license agreement with the licensor that is type certificated by
the CAA of other Contracting State; or
(c) a design organization intends to integrate an aeronautical product viz.
aircraft engine and/or propeller, certified by the CAA of other Contracting
State, on an aircraft for which application has been submitted to DGCA for
issuance of TC/RTC.
4. Requirements:
4.1 The application shall be submitted by the TC/RTC/STC holder as per
Annexure I, II, III & IV (as applicable), to the Director, Aircraft Engineering
Directorate (AED), DGCA
4.2 The application shall be forwarded through the CAA of the State of Design to
the DGCA.
Note:-When an Indian operator intends to incorporate a STC (Supplemental
Type Certificate) or multiple STCs certified by the CAA of a contracting state,
same is/are required to be type accepted by the DGCA. In such case/s, the
Rev. 05 XXXX 2025 2CIVIL AVIATION REQUIREMENTS SECTION 6
SERIES A PART II 7th OCTOBER 2014
STC holder shall submit an application to the DGCA, along with evidence that
the CAA of the State of Design has been intimated by the STC .
4.3 The operator shall not import an aeronautical product in the country, without
having the Letter of Type Acceptance (LoTA) issued from DGCA.
4.4 The operator shall not import an aeronautical product based on earlier model
accepted by DGCA if:
a) there are any changes in the certification basis in the TCDS vis-à-vis
earlier accepted TCDS (Revision No.) with respect to the model; or
b) the TCDS has undergone revisions/ updation due to major changes in
the type design including changes to approved airworthiness and
operating limitations.
Note: The applicant is required to submit application as per this CAR through
their CAA for re-issue of LoTA with updated TCDS Revision No. to meet
requirement specified in 4.4 above.
4.5 Aircraft type acceptance, shall be considered complete, only when engine
and/or propeller as product, embedded in the aircraft, is also type accepted
by DGCA in accordance with this CAR.
4.6 DGCA at its discretion may ask any additional information/documentation/
clarification from the TC/RTC/STC holder.
4.7 The applicant (TC/RTC/STC holder, as the case may be) shall arrange
familiarization programme of adequate duration for DGCA (AED) officials,
depending on the complexity, type of aeronautical product, type of design
change (significant), at their facility.
4.8 The applicable fees for acceptance of TC/RTC/STC are specified in Rule 62
of The Aircraft Rules, 1937 (available in DGCA website www.dgca.gov.in) and
are required to be paid online through the web portal
https://bharatkosh.gov.in.
5. Issue/ Cancellation of Letter of Type Acceptance (LoTA):
5.1 Upon being satisfied, DGCA may grant LoTA (for TC/RTC/STC) w.r.t the
model, which shall be communicated to the TC/RTC/STC holder, CAA of the
State of Design and the operator with additional conditions, if any.
5.2 If at any point of time, the DGCA finds that there is a reasonable doubt to
indicate that the safety of the aeronautical product is imperiled because of an
unsafe condition developed in the aeronautical product, or that the said
acceptance has been obtained based on false documents, DGCA may cancel
the ‘Letter of Type Acceptance’.
