DEPARTMENT OF TRANSPORTATION 

Federal Aviation Administration 

Aviation Rulemaking Advisory 

Committee Engine Endurance Testing 

Requirements—New Task 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of new task assignment 

for the Aviation Rulemaking Advisory 

Committee (ARAC). 

SUMMARY: The FAA assigned ARAC a 

new task to review existing engine 

endurance test requirements, assess its 

suitability for all engines, and consider 

an alternate endurance test and 

associated methods of compliance. The 

current regulations may not adequately 

address the technological advances 

found in modern engines, as related to 

the current engine endurance test. This 

notice informs the public of the new 

ARAC activity and solicits membership 

for the Engine Harmonization Working 

Group (EHWG).

SUPPLEMENTARY INFORMATION: 

ARAC Task Acceptance 

ARAC accepted the task and assigned 

the task to the EHWG, under the 

Transport Airplane and Engine (TAE) 

Subcommittee. The working group will 

serve as staff to ARAC and assist ARAC 

by providing advice and 

recommendations of the assigned tasks. 

ARAC must review and approve the 

working group’s recommendation report 

before it will forward it to the FAA. 

Background 

The FAA established ARAC to 

provide advice and recommendations to 

the FAA Administrator, through the 

Associate Administrator for Aviation 

Safety, on the FAA’s rulemaking 

activities. This includes obtaining 

advice and recommendations on the 

FAA’s commitments to harmonize Title 

14 of the Code of Federal Regulations 

(14 CFR) with appropriate foreign 

authorities’ regulations. ARAC’s 

objectives are to improve the 

development of the FAA’s regulations 

by providing information, advice, and 

recommendations related to aviation 

issues. 

The EHWG will provide advice and 

recommendations to ARAC on existing 

and alternate endurance tests and 

associated methods of compliance. 

The engine endurance test is an 

accelerated severity test intended to 

demonstrate a minimum level of engine 

operability and durability within the 

approved engine ratings and operating 

limitations. The test running conditions 

cover the declared engine rating and 

operating limitations, but are not 

intended to simulate the expected inservice operation. To run the test at 

simultaneous speed and temperature 

limits, applicants may need to modify 

the test engine configuration and the 

required test sequence. 

The current practice and accepted 

methods of compliance allow 

modifications to the test engine 

configuration and test sequence, 

provided certain conditions are met. 

Specifically, that the engine, as 

modified, still represents the durability 

and operating characteristics of the 

intended type design and complies with 

§ 33.87 requirements. However, 

experience with past engine 

certifications shows that for some 

engines, those modifications are 

substantial enough that the engine is not 

conforming to its type design, thus 

affecting the test outcome. These 

difficulties occur because the required 

test in § 33.87 has not been updated to 

account for technological advances in 

gas turbine engines and in-service 

operational characteristics. 

The endurance test requirements 

originated with the reciprocating engine 

and were later revised for single-shaft 

turbine engines with mechanical 

controls. The test running conditions 

were designed to match the engine 

design and operational characteristics 

during that time and have remained the 

same for the past 60 years. Today’s 

engines have evolved by up to 10 times 

increased compression ratio and 40 

times increased airflow. They 

incorporate advanced technologies that 

include three-shaft designs, high-bypass 

turbofans, sophisticated full authority 

digital electronic controls, and complex 

turbine cooling. Other technological 

advances provide in-service engine 

health monitoring, thus improving 

engine reliability and increased mean 

time on wing. Modern engine 

technologies allow up to 50% lower 

specific-fuel consumption and 

significant emissions and noise 

improvements. 

Certification experience shows that, 

due to the complexity of modern 

engines, the modifications needed to 

run the required endurance test are 

substantial, greatly affecting the engine 

operating cycle and causing reduced 

airflow, less cooling, or increased 

temperatures. To compensate for these 

undesirable effects, applicants make 

additional engine modifications, such as 

modifying cooling circuits, grinding 

blade tips, or adding thermal barrier 

coating to blades. As a result of these 

modifications, it becomes increasingly 

difficult to show that the test engine 

conforms to the type design. The 

objective of the ARAC task is to evaluate 

whether the requirements for engine 

endurance testing should be revised by 

adding requirements for an alternate 

test.

The Task 

The EHWG is to review and assess the 

standards and advisory material for 14 

CFR 33.87, engine endurance test 

requirements as follows: 

1. Develop an alternate endurance test 

that would allow an engine to be tested 

in the configuration representative of its 

type design, and 

a. Maintain compliance with the 

intent, as well as the basic elements 

currently in § 33.87, including the 

ratings, operating limitations, and 

engine configuration. 

b. The alternate test is to be 

equivalent to the test currently in 

§ 33.87 with regards to demonstrating 

engine operability and durability, and is 

validated with engine data. The engine 

data must include experience, 

certification, and additional component 

and engine tests. 

2. Develop and document 

recommended: 

a. Methods of compliance, and 

b. Rule changes, if considered 

necessary. 

3. Review the current foreign 

requirements for engine endurance test 

and determine the need for harmonizing 

any new methodologies. 

4. Provide initial qualitative and 

quantitative estimates of costs and 

benefits for any new methodologies. 

5. Develop a report containing the 

recommendations for rulemaking or 

guidance material, or both, and explain 

the rationale and safety benefits for each 

proposed change. 

6. The working group may be 

reinstated to assist the ARAC by 

responding to the FAA’s questions or 

concerns after the recommendation 

report has been submitted. 

The final ARAC recommendation 

report should include a summary of the 

overall work scope, conclusions, and 

rationale for all recommendations 

related to the above tasks. It should 

document both majority and minority 

positions on the findings, and the 

rationale for each position and reasons 

for any disagreement. Any 

disagreements should be documented, 

including the rationale for each position 

and the reasons for the disagreement. 

Schedule 

The recommendation report must be 

submitted to the FAA for review and 

acceptance no later than December 31, 

2015. 

Working Group Activity 

The EHWG must comply with the 

procedures adopted by the ARAC. As 

part of the procedures, the working 

group must: 

1. Conduct a review and analysis of 

the assigned tasks, including any related 

materials or documents. 

2. Draft and submit a work plan for 

completion of the task, including the 

rationale supporting such a plan for 

TAE Subcommittee consideration. 

3. Provide a status report at each TAE 

Subcommittee public meeting. 

4. Draft and submit the 

recommendation report based on the 

review and analysis of the assigned 

tasks and any related materials or 

documents. 

5. Present the recommendation at a 

TAE Subcommittee public meeting. 

6. The TAE Subcommittee Chair will 

provide a status report at each ARAC 

public meeting and present the final 

recommendation to ARAC for review 

and approval. ARAC will forward the 

recommendation to the FAA. 

Participation in the Working Group 

The EHWG will be composed of 

technical experts having an interest in 

the assigned task. A working group 

member does not need to be a member 

representative of the ARAC. The FAA 

would like a wide range of members on 

the working group to ensure all aspects 

of the tasks are considered in 

development of the recommendations. 

However, the June 18, 2010 

memorandum, ‘‘Lobbyists on Agency 

Boards and Commissions,’’ states that a 

member must not be a federally 

registered lobbyist who is subject to the 

registration and reporting requirements 

of the Lobbying Disclosure Act of 1995 

(LDA) as amended, 2 U.S.C 1603, 1604, 

and 1605, at the time of appointment or 

reappointment to an advisory 

committee, and has not served in such 

a role for a two-year period prior to 

appointment. Therefore, the FAA will 

not select any person that is a registered 

lobbyist. For further information see the 

Office of Management and Budget final 

guidance on appointment of lobbyists to 

federal boards and commissions (76 FR 

61756, October 5, 2011). 

If you have expertise in the subject 

matter and wish to become a member of 

the working group, write to the person 

listed under the caption FOR FURTHER

INFORMATION CONTACT expressing that 

desire. Describe your interest in the task 

and state the expertise you would bring 

to the working group. The FAA must 

receive all requests by February 11, 

2014. The ARAC and the FAA will 

review the requests and advise you if 

they approve or disapprove your 

request. 

If you are chosen as a member on the 

working group, you must represent your 

aviation community segment and 

actively participate in the working 

group by attending all meetings and 

providing written comments when 

requested to do so. You must devote the 

resources necessary to support the 

working group in meeting any assigned 

deadlines. You must keep your 

management, and those you may 

represent, advised of the working group 

activities and decisions to ensure that 

the proposed technical solutions do not 

conflict with the position of those you 

represent when the proposed 

recommendations are presented to the 

subcommittee and ARAC for approval. 

Once the working group has begun 

deliberations, they will not add or 

substitute members without the 

approval of the TAE Subcommittee 

Chair, FAA Representatives, including 

the Designated Federal Officer, and the 

working group. 

The Secretary of Transportation 

determined that the ARAC formation 

and use is necessary, and in the public 

interest, in connection with the 

performance of duties imposed on the 

FAA by law. 

ARAC meetings are open to the 

public. Meetings held by the EHWG will 

not be open to the public, except to 

individuals selected to participate based 

on interest and expertise. We will make 

no public announcement of working 

group meetings.
