ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directive (AD) 2014–07– 

04R1 for certain Sikorsky Model S–92A 

helicopters. AD 2014–07–04R1 

currently requires repetitive inspections 

in the upper deck area for incorrectly 

installed clamps and chafing between 

the electrical wires and the hydraulic 

lines and replacing any unairworthy 

wires or hydraulic lines. Since we 

issued AD 2014–07–04R1, the 

manufacturer has developed an 

alteration that corrects the unsafe 

condition described in AD 2014–07– 

04R1. This proposed AD would require 

altering the wiring system in the upper 

deck area. These proposed actions are 

intended to prevent a fire in an area of 

the helicopter without extinguishing 

capability and subsequent loss of 

control of the helicopter. 

DATES: We must receive comments on 

this proposed AD by November 24, 

2015.

proposal in light of the comments we 

receive. 

Discussion 

On March 28, 2014, we issued AD 

2014–07–04, Amendment 39–17818 (79 

FR 21385, April 16, 2014), for certain 

serial-numbered Sikorsky Model S92A 

helicopters. AD 2014–07–04 required 

repetitively inspecting the upper deck 

area for incorrectly installed clamps and 

chafing between the electrical wires and 

the hydraulic lines, replacing any 

unairworthy wires or hydraulic lines, 

and correcting any clamps that were 

installed incorrectly. Due to 

typographical errors when the AD was 

published, an incorrect serial number 

and an incorrect reference to the service 

information appeared in the text of the 

rule. On August 21, 2014, we issued AD 

2014–07–04R1, Amendment 39–17964 

(79 FR 54893, September 15, 2014), to 

correct these errors. 

Actions Since AD 2014–07–04R1 Was 

Issued 

Since we issued AD 2014–07–04R1 

(79 FR 54893, September 15, 2014), 

Sikorsky has developed an alteration to 

correct the unsafe condition described 

in AD 2014–07–04R1. The alteration 

creates separate engine inlet and 

alternating current (AC) generator feeder 

lines, which were previously combined 

as an assembly. The new engine inlet 

feeder lines are rerouted through the 

cabin to the AC power distributors. The 

alteration also involves removing 

certain hydraulic to electrical clamps, 

which support the top deck main 

harnesses, and adding independent 

electrical brackets to create greater 

separation from the hydraulic lines. 

These proposed actions are intended to 

alter the wiring installation in the upper 

deck to prevent chafing between the 

electrical lines and hydraulic hoses. 

This condition, if not prevented, could 

result in a fire in an area of the 

helicopter without extinguishing 

capability and subsequent loss of 

control of the helicopter. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all the relevant information 

and determined the unsafe condition 

described previously is likely to exist or 

develop in other products of this same 

type design. 

Related Service Information Under 1 

CFR Part 51 

Sikorsky has issued Special Service 

Instructions SSI No. 92–070A, Revision 

A, dated April 25, 2014 (SSI 92–070A), 

which contains procedures to alter the 

wiring system in the upper deck area to 

prevent chafing. This service 

information is reasonably available 

because the interested parties have 

access to it through their normal course 

of business or by means identified in the 

Addresses Section of this proposed AD. 

Other Related Service Information 

We also reviewed Alert Service 

Bulletin ASB 92–20–003, Basic Issue, 

dated May 5, 2014 (ASB 92–20–003). 

ASB 92–20–003 specifies a one-time 

modification of the upper deck wiring 

harnesses to prevent possible chafing by 

complying with SSI 92–070A. 

Proposed AD Requirements 

This proposed AD would require 

altering the wiring system in the upper 

deck area. 

Differences Between This Proposed AD 

and the Service Information 

The service information provides a 

compliance date of November 5, 2015; 

the proposed AD would require a 

compliance time of 150 hours TIS. Also, 

the service information requires 

submitting certain documentation to the 

manufacturer, and the proposed AD 

would not. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 20 helicopters of U.S. 

Registry. 

We estimate that operators may incur 

the following costs in order to comply 

with this AD. Labor costs are estimated 

at $85 per work hour. Rerouting the 

upper deck wiring system and replacing 

and installing new parts would take 58 

work hours and $8,000 in required 

parts, for a total cost of $12,930 per 

helicopter and $258,600 for the fleet. 

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.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Alpha Aviation Concept Limited Model 

R2160 airplanes that would supersede 

AD 2008–09–01. This proposed AD 

results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as a need to revise the 

maintenance program to include the 

revised airworthiness limitations for the 

internal wing structure and wing 

attachment inspections. We are issuing 

this proposed AD to require actions to 

address the unsafe condition on these 

products.
