AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Burkhart GROB Luft- und Raumfahrt 

GmbH Models GROB G 109 and GROB 

G 109B powered sailplanes. This AD 

results from mandatory continuing 

airworthiness information (MCAI) 

issued 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 excessive corrosion on the 

nose plate in the vertical stabilizer, 

which could cause the vertical stabilizer 

nose plate to fail. We are issuing this AD 

to require actions to address the unsafe 

condition on these products. 

DATES: This AD is effective July 9, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of July 9, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on March 23, 2012 (77 FR 

16968). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Occurrences have been reported of finding 

heavily corroded nose plates, part number 

(P/N) 109–2160.01, in the vertical stabiliser 

of some Grob G 109 powered sailplanes. 

The investigation results concluded that 

the affected aeroplanes were based and 

operated near the seaside and therefore 

exposed to a salty environment, causing the 

excessive corrosion. 

This condition, if not detected and 

corrected, could lead to failure of the vertical 

stabilizer nose plate, which functions as a 

horizontal stabiliser fitting, to support limit 

loads and consequent loss of control of the 

aeroplane. 

For the reasons described above, this AD 

requires repetitive inspections and, 

depending on findings, replacement of the 

nose plate. 

You may obtain further information 

by examining the MCAI in the AD 

docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (77 

FR 16968, March 23, 2012) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

16968, March 23, 2012) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 16968, 

March 23, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

59 products of U.S. registry. We also 

estimate that it will take about 6 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $424 per 

product. 

Based on these figures, we estimate 

the cost of the AD on U.S. operators to 

be $55,106, or $934 per product. 

In addition, we estimate that any 

necessary follow-on actions will take 

about 12 work-hours and require parts 

costing $243, for a cost of $1,263 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

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 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 this AD: 

(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, 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. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Management Facility between 

9 a.m. and 5 p.m., Monday through 

Friday, except Federal holidays. The AD 

docket contains the NPRM (77 FR 

16968, March 23, 2012), the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Office (telephone (800) 647– 

5527) is in the ADDRESSES section. 

Comments will be available in the AD 

docket shortly after receipt.

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all The 

Boeing Company Model 777 airplanes. 

This AD was prompted by four reports 

of retaining cross bolt hardware not 

fully engaged into the fuse pins of the 

forward trunnion lower housing of the 

main landing gear (MLG), which could 

result in an incorrect MLG emergency 

landing break-away sequence. This AD 

requires a detailed inspection of the fuse 

pin cross bolts and fuse pins of the left 

and right MLG forward trunnion lower 

housing to verify that the cross bolts are 

correctly installed and that there are no 

missing fuse pins, and replacement of 

the fuse pins if necessary. We are 

issuing this AD to prevent an incorrect 

emergency landing MLG break-away 

sequence, which could result in 

puncturing of the wing box and 

consequent fuel leaks and an airplane 

fire. Failure of the fuse pins could also 

result in a possible landing gear collapse 

causing a runway excursion during takeoff or landing. 

DATES: This AD is effective July 9, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of July 9, 2012.
