Airworthiness Directives; Sikorsky 

Aircraft Corporation Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for 

Sikorsky Aircraft Corporation (Sikorsky) 

Model S–92A helicopters to require 

modifying the No. 1 engine forward 

firewall center fire extinguisher 

discharge tube (No. 1 engine tube). This 

proposed AD is prompted by the 

discovery that the No. 1 engine tube 

installed on the helicopters is too long 

to ensure that a fire could be effectively 

extinguished on a helicopter. The 

proposed actions are intended to ensure 

the No. 1 engine tube would allow for 

complete coverage of an extinguishing 

agent in the No. 1 engine compartment 

area, ensure that a fire would be 

extinguished and prevent the loss of 

helicopter control. 

DATES: We must receive comments on 

this proposed AD by June 21, 2013. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Docket: Go to

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to participate in this 

rulemaking by submitting written 

comments, data, or views. We also 

invite comments relating to the 

economic, environmental, energy, or 

federalism impacts that might result 

from adopting the proposals in this 

document. The most helpful comments 

reference a specific portion of the 

proposal, explain the reason for any 

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should send only one copy 

of written comments, or if comments are 

filed electronically, commenters should 

submit only one time. 

We will file in the docket all 

comments that we receive, as well as a 

report summarizing each substantive 

public contact with FAA personnel 

concerning this proposed rulemaking. 

Before acting on this proposal, we will 

consider all comments we receive on or 

before the closing date for comments. 

We will consider comments filed after 

the comment period has closed if it is 

possible to do so without incurring 

expense or delay. We may change this 

proposal in light of the comments we 

receive. 

Discussion 

We propose to adopt a new 

airworthiness directive (AD) for 

Sikorsky Aircraft Corporation (Sikorsky) 

Model S–92A helicopters with serial 

numbers (S/N) 920006 through 920169. 

This proposed AD is prompted by a 

recent event where an extinguishing test 

at a Sikorsky plant showed that an 

incorrect No. 1 engine tube length had 

been put into production. Because of the 

incorrect tube length, if a fire erupts in 

the engine compartment, the fireextinguishing system may not discharge 

the agent completely throughout the 

compartment to extinguish the blaze. 

This proposed AD would require 

removing the No. 1 engine tube, cutting 

off two inches from the discharge end of 

the tube, and inspecting the outboard 

discharge tube and positioning both 

tubes to ensure that they would provide 

complete coverage of the extinguishing 

agent in the No. 1 engine compartment 

area to ensure that a fire can be 

extinguished. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all known relevant 

information and determined that an 

unsafe condition exists and is likely to 

exist or develop on other products of 

these same type designs. 

Related Service Information 

Sikorsky has issued Alert Service 

Bulletin 92–26–004 (ASB), dated June 4, 

2012, to modify the No. 1 engine tube 

within 120 days. The ASB specifies 

procedures to cut two inches off the 

tube’s discharge end, as well as how to 

inspect and reposition, if necessary, the 

outboard discharge tube. 

Proposed AD Requirements 

This proposed AD would require 

removing the No. 1 engine tube, 

removing two inches from the discharge 

end of the tube, and then require 

inspecting the outboard discharge tube 


tkelley on DSK3SPTVN1PROD with PROPOSALS
Federal Register / Vol. 78, No. 77 / Monday, April 22, 2013 / Proposed Rules 23699 

for correct positioning. If the outboard 

discharge tube is not correctly 

positioned, this proposed AD would 

require correcting the positioning. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 24 U.S. registered 

helicopters and that labor costs would 

average $85 per work-hour. Based on 

these estimates, we expect the following 

costs: 

• Modifying the No. 1 engine tube 

would take two work-hours for an 

estimated labor cost of $170 per 

helicopter. No parts would be needed, 

so the cost for the U.S. fleet would total 

$4,080. 

• Inspecting the outboard discharge 

tube and ensuring that it is in the 

required position would take about one 

work-hour for a total labor cost of $85 

per helicopter. No parts would be 

needed for a total U.S. fleet cost of 

$2,040. 

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

section 106, describes the authority of 

the FAA Administrator. ‘‘Subtitle VII: 

Aviation Programs,’’ describes in more 

detail the scope of the Agency’s 

authority. 

We are issuing this rulemaking under 

the authority described in ‘‘Subtitle VII, 

Part A, Subpart III, Section 44701: 

General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We determined that this proposed AD 

would not have federalism implications 

under Executive Order 13132. This 

proposed AD would not have a 

substantial direct effect on the States, on 

the relationship between the national 

Government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed, I certify 

this proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); 

3. Will not affect intrastate aviation in 

Alaska to the extent that it justifies 

making a regulatory distinction; and 

4. Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared an economic evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.
