The Government of the United States of America

and the Government of the Republic of

Singapore, hereinafter referred to as "the

Parties",

Desiring to promote aviation safety and

environmental quality, and, eventually, to

replace the Agreement between the United States

of America and the Republic of Singapore

relating to the reciprocal acceptance of

airworthiness certifications, effected by

exchange of notes at Singapore on August 21,

1981;

Noting common concerns for the safe operation

of civil aircraft;

Recognizing the emerging trend toward

multinational design, production, and

interchange of civil aeronautical products;

Desiring to enhance cooperation and increase

efficiency in matters relating to civil

aviation safety;

Considering the possible reduction of the

economic burden imposed on the aviation

industry and operators by redundant technical

inspections, evaluations, and testing;

Recognizing the mutual benefit of improved

procedures for the reciprocal acceptance of

airworthiness approvals, environmental testing,

and development of reciprocal recognition

procedures for approval and monitoring of

flight simulators, aircraft maintenance

facilities, maintenance personnel, flight crew

members, and flight operations,

Have agreed as follows:
ARTICLE I

A. The Parties agree:

1. To facilitate acceptance by each Party of

the other Party's (a) airworthiness approvals

and environmental testing and approval of civil

aeronautical products, and (b) qualification

evaluations of flight simulators;

2. To facilitate acceptance by the Parties of

the approvals and monitoring of maintenance

facilities and alteration or modification

facilities, maintenance personnel, flight crew

members, aviation training establishments, and

flight operations of the other Party;

3. To provide for cooperation in sustaining an

equivalent level of safety and environmental

objectives with respect to aviation safety.

B. Each Party hereby designates its civil

aviation authority as the executive agent to

implement this Agreement. For the Government

of the United States, the executive agent shall

be the Federal Aviation Administration (FAA) of

the Department of Transportation. For the

Government of the Republic of Singapore, the

executive agent shall be the Civil Aviation

Authority of Singapore (CAAS).

ARTICLE II

For the purposes of this Agreement:

A. "Airworthiness approval" means a finding

that the design or change to a design of a

civil aeronautical product meets standards

agreed between the Parties or that a product

conforms to a design that has been found to

meet those standards, and is in a condition for

safe operation.

B. "Alterations or modifications" means making

a change to the construction, configuration,

performance, environmental characteristics, or

operating limitations of the affected civil

aeronautical product.

Parties, of an entity providing commercial air

transportation of passengers or cargo, or the

finding that the entity complies with those

standards.

D. "Civil aeronautical product" means any

civil aircraft, aircraft engine, or propeller

or subassembly, appliance, material, part, or

component to be installed thereon.

E. "Environmental approval" means a finding

that a civil aeronautical product complies with

standards agreed between the Parties concerning

noise and/or exhaust emissions.

F. "Environmental testing" means a process by

which a civil aeronautical product is evaluated

for compliance with those standards, using

procedures agreed between the Parties.

G. "Flight crew member" means a pilot, flight

engineer or flight navigator assigned to duty

in an aircraft during flight time.

H. "Flight simulator qualification

evaluations" means the qualification process by

which a flight simulator is assessed by

comparison to the aircraft it simulates, in

accordance with standards agreed between the

Parties, or the finding that it complies with

those standards.

I. "Maintenance" means the performance of

inspection, overhaul, repair, preservation, and

the replacement of parts, materials,

appliances, or components of a product to

surveillance by the civil aviation authority of

a Party to determine continuing compliance with

the appropriate standards.
ARTICLE III

A. The Parties' civil aviation authorities

shall conduct technical assessments and work

cooperatively to develop an understanding of

each other's standards and systems in the

following areas:

1. Airworthiness approvals of civil

aeronautical products;

2. Environmental approval and environmental

testing;

3. Approval and monitoring of maintenance

facilities and maintenance personnel;

4. Approval and monitoring of flight

operations and flight crew members;

5. Evaluation and qualification of flight

B. When the civil aviation authorities of the

Parties agree that the standards, rules,

practices, procedures, and systems of both

Parties in one of the technical specialties

listed in paragraph (A) of this Article are

sufficiently equivalent or compatible to permit

acceptance of findings of compliance made by

one Party for the other Party to the agreedupon standards, the civil aviation authorities

shall execute written Implementation Procedures

describing the methods by which such reciprocal

acceptance shall be made with respect to that

technical specialty. Once the written

Implementation Procedures are executed the

Implementation Procedures, which shall be

considered implementing agreements under this

include at a minimum:

1. Definitions;
2. A description of the scope of the

particular area of civil aviation to be

addressed;

3. Provisions for reciprocal acceptance of
