SUPPLEMENTARY INFORMATION: 

Discussion 

A number of service documents and 

ADs have been issued relating to the 

ERB on this and similar model 

helicopters. AD 82–17–03, issued July 

30, 1982 (47 FR 35469, August 16, 

1982), requires a puck-to-disc 

inspection of rotor brake, P/N 76363– 

09101–101, and modification of the ERB 

system including, among other 

modifications, installation of a warning 

relay by following Sikorsky Customer 

Service Bulletin No. 76–66–10B, 

Revision 2, dated November 25, 1981 

(pages 1 and 9 through 13 of the service 

bulletin are dated November 25, 1981 

and pages 2 through 8 are dated July 30, 

1981). AD 2003–04–15, issued February 

14, 2003 (68 FR 8994, February 27, 

2003), requires inspecting certain rotor 

brake discs for cracks that resulted from 

improper heat treating of the disc. 

On October 26, 2011, at 76 FR 66205, 

the Federal Register published our 

notice of proposed rulemaking (NPRM), 

which proposed to amend 14 CFR part 

39 to include an AD that would apply 

to Sikorsky Model S–76A helicopters 

with a different part-numbered ERB, 

part number (P/N) 76363–09100–012, 

installed. That NPRM proposed to 

require, within 120 days, modifying the 

ERB by installing and operationally 

testing the parts contained in an ERB 

warning relay kit (P/N 76070–55023– 

011), an ERB circuit modification kit 

(P/N 76070–55033–012), and an ERB 

modification kit (P/N 76070–55207– 

011). That NPRM was prompted by a 

reported incident of a fire occurring in 

an ERB installed on a Model S–76A 

helicopter in Brazil. The proposed 

requirements were intended to prevent 

overheating of the ERB assembly, 

ignition of the ERB hydraulic fluid, fire 

in the main gearbox area, and 

subsequent loss of control of the 

helicopter. 

Related Service Information 

We have reviewed the following 

documents from Sikorsky: 

• Customer Service Bulletin No. 76– 

66–10B, Revision 2, dated November 25, 

1981 (pages 1 and 9 through 13 of the 

service bulletin are dated November 25, 

1981 and pages 2 through 8 are dated 

July 30, 1981), which specifies installing 

an ERB warning relay kit; 

• Customer Service Notice No. 76– 

113, dated June 1, 1983, which specifies 

installing an ERB circuit breaker and 

modification kit; 

• Alert Service Bulletin No. 76–66– 

48B, Revision B, dated July 8, 2009, 

which specifies a one-time installation 

of an ERB modification kit containing 

two other kits and several 

modifications; and 

• RFM Supplement No. 41, Part 1, 

approved September 6, 2005, which 

revises the information in the basic RFM 

normal and emergency procedures 

sections when the ERB system is 

modified. 

Comments 

We gave the public the opportunity to 

participate in developing this AD, but 

we did not receive any comments on the 

NPRM. 

FAA’s Determination 

We have reviewed the relevant 

information and determined that an 

unsafe condition exists and is likely to 

exist or develop on other products of the 

same type design and that air safety and 

the public interest require adopting the 

AD requirements as proposed, except 

for editorial changes. These editorial 

changes are consistent with the intent of 

the proposals and will not increase the 

economic burden on any operator nor 

increase the scope of the AD. 

Costs of Compliance 

We estimate that this AD will affect 

180 helicopters of U.S. Registry. We 

estimate that operators may incur the 

following costs in order to comply with 

this AD. It will take about 38 workhours per helicopter to perform the 

modifications and operational tests at an 

average labor rate of $85 per work-hour. 

Required parts will cost $13,300 per 

helicopter. Based on these figures, we 

estimate the total cost impact of the AD 

on U.S. operators to be $2,975,400 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 

This AD will not have federalism 

implications under Executive Order 

13132. This AD will 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 above, I 

certify that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

(2) Is not a ‘‘significant rule’’ under 

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 AD and placed it in the AD docket.

Amendment to Class B Airspace; Salt 

Lake City, UT 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action modifies the Salt 

Lake City, UT, Class B airspace to 

contain aircraft conducting Instrument 

Flight Rules (IFR) instrument approach 

procedures to Salt Lake City 

International Airport (SLC), Salt Lake 

City, UT. The FAA is taking this action 

to improve the flow of air traffic, 

enhance safety, and reduce the potential 

for midair collision, while 

accommodating the concerns of airspace 

users. Further, this effort supports the 

FAA’s national airspace redesign goal of 

optimizing terminal and en route 

airspace to reduce aircraft delays and 

improve system capacity. Minor 

corrections have been made to the 

geographic coordinates of the affected 

legal descriptions, as well as editorial 

corrections. 

DATES: Effective Date: 0901 UTC, 

October 18, 2012. The Director of the 

Federal Register approves this 

incorporation by reference action under 

1 CFR part 51, subject to the annual 

revision of FAA Order 7400.9 and 

publication of conforming amendments.

SUPPLEMENTARY INFORMATION: 

History 

On August 24, 2011, the FAA 

published in the Federal Register a 

notice of proposed rulemaking (NPRM) 

to modify the Salt Lake City, UT, Class 

B airspace area (76 FR 52905). Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal. 

Eight written comments were received 

in response to the NPRM. All comments 

received were considered before making 

a determination on the final rule. 

Class B airspace designations are 

published in paragraph 3000 of FAA 

Order 7400.9V, dated August 9, 2011, 

and effective September 15, 2011, which 

is incorporated by reference in 14 CFR 

71.1. The Class B airspace designations 

listed in this document will be 

subsequently published in the Order. 

Discussion of Comments 

Four commenters opposed the vertical 

extension of the Salt Lake City Class B 

airspace from 10,000 feet MSL to 12,000 

feet MSL without mitigating impacts on 

VFR operations. They challenged the 

operational and safety benefit of raising 

the ceiling based on no actual mid-air 

collision or conflict resolution data 

having been provided to support taking 

this action.
