ACTION: Final rule; request for comments. AGENCY: We are adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model G–IV, GIV–X, GV, and GV–SP airplanes. This AD requires measuring to determine paint thickness on the flight control surfaces and corrective actions if necessary, and revising the Airplane Flight Manual (AFM). This AD was prompted by reports of failure to inspect or document the paint thickness on flight controls (ailerons, rudder, elevator), potentially having a negative impact on the flutter characteristics of the airplane. We are issuing this AD to detect and correct paint thickness on flight controls, which could result in loss of control of the airplane due to flutter. SUMMARY: This AD is effective August 1, 2012. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of August 1, 2012. We must receive comments on this AD by August 31, 2012.

SUPPLEMENTARY INFORMATION: sroberts on DSK5SPTVN1PROD with RULES Discussion We received reports of failure to inspect or document the paint thickness on flight controls (ailerons, rudder, elevator), potentially having a negative impact on the flutter characteristics of the airplane. Excessive paint thickness will affect the balance moment of the flight control surface. This condition, if not corrected, could result in loss of control of the airplane due to flutter. Relevant Service Information We reviewed the following service information, which describes procedures for measuring the paint thickness on both sides of each flight control surface (ailerons, rudder, and elevator) and corrective actions if necessary. The customer bulletins also describe procedures for revising the AFM to advise the flightcrew to not exceed a certain altitude until corrective actions have been accomplished. Corrective actions include removing the flight control surface and rebalancing, stripping, repainting with an average thickness less than 5.0 mils, and sanding/buffing down to 5.0 mils or less VerDate Mar<15>2010 19:47 Jul 16, 2012 Jkt 226001 and re-measuring thicknesses (not recommended on surfaces with averages exceeding 7.0 mils). • For Model G–IV airplanes: Gulfstream IV Customer Bulletin 223, including Part I and Part II Service Reply Cards, dated March 23, 2012, which includes Gulfstream GIV Airplane Flight Manual Supplement GIV–2012–01, dated March 13, 2012. • For Model GV airplanes: Gulfstream V Customer Bulletin 196, including Part I and Part II Service Reply Cards, dated March 23, 2012, which includes Gulfstream GV Airplane Flight Manual Supplement GV–2012–01, dated March 13, 2012. • For Model GIV–X airplanes: Gulfstream G450 Customer Bulletin 140, including Part I and Part II Service Reply Cards, dated March 23, 2012, which includes Gulfstream G450/G350 Airplane Flight Manual Supplement G450–2012–01, dated March 13, 2012. • For Model GV–SP airplanes: Gulfstream G550 Customer Bulletin 121, including Part I and Part II Service Reply Cards, dated March 23, 2012, which includes Gulfstream G550 Airplane Flight Manual Supplement G550–2012–01, dated March 13, 2012; and Gulfstream G550 EASA Airplane Flight Manual Supplement EASA– G550–2012–01, dated March 14, 2012. FAA’s Determination We are issuing 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 these same type designs. AD Requirements This AD requires accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between the AD and the Service Information.’’ This AD also requires sending the measurement and corrective action results to Gulfstream Aerospace Corporation. Differences Between the AD and the Service Information The customer bulletins specified in paragraph (g) of this AD incorporate the airplane flight manual supplement (AFMS) as an on-condition action. This AD requires operators to incorporate the AFMS within 20 days after the effective date of this AD. We have determined that this action is necessary to address the identified unsafe condition. Although the customer bulletins specified in paragraph (g) of this AD PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 specify that operators may contact the manufacturer for disposition of certain repair conditions, this AD requires operators to repair those conditions in accordance with a method approved by the FAA. FAA’s Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule, because we received reports of failure to inspect or document the paint thickness on flight controls (ailerons, rudder, elevator), potentially having a negative impact on the flutter characteristics of the airplane. Excessive paint thickness will affect the balance moment of the flight control surface. This condition, if not corrected, could result in loss of control of the airplane due to flutter. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA–2012–0677 and Directorate Identifier 2012–NM–105–AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance We estimate that this AD affects 33 airplanes of U.S. registry. We estimate the following costs to comply with this AD: E:\FR\FM\17JYR1.SGM 17JYR1 Federal Register / Vol. 77, No. 137 / Tuesday, July 17, 2012 / Rules and Regulations 41893 ESTIMATED COSTS Action Labor cost Measurement ...................................................... Airplane flight manual revision ............................ 5 work-hours × $85 per hour = $425 ................. 1 work-hour × $85 per hour = $85 ..................... We have received no definitive data that would enable us to provide a cost estimate for the on-condition actions specified in this AD. According to the manufacturer, the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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. sroberts on DSK5SPTVN1PROD with RULES 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.

ACTION: Final rule. AGENCY: We are superseding an existing airworthiness directive (AD) for certain The Boeing Company Model 767–200 and –300 series airplanes. That AD currently requires replacement of the existing deactivation pin, aft cascade pin bushing, and pin insert on each thrust reverser half with new, improved components. This new AD requires a dye penetrant inspection for cracking of the rivet holes of the bushing plate and repair or replacement, if necessary; and for certain airplanes, replacing the existing bushing with a new bushing and deactivation pin, and installing a new or serviceable stowage bracket for the deactivation pins on all airplanes powered by Pratt & Whitney JT9D series engines. This AD was prompted by reports that certain airplanes require installation of a new bushing and deactivation pin with increased load carrying capability and all airplanes powered by Pratt & Whitney JT9D series engines require installation of a new bracket for stowing the deactivation pin. We are issuing this AD to prevent failure of the thrust reverser deactivation pins, which could fail to prevent a deployment of a deactivated thrust reverser in flight and consequent reduced controllability of the airplane.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Gulfstream Aerospace Corporation Model G-IV, GIV-X, GV, and GV-SP 
airplanes. This AD requires measuring to determine paint thickness on 
the flight control surfaces and corrective actions if necessary, and 
revising the Airplane Flight Manual (AFM). This AD was prompted by 
reports of failure to inspect or document the paint thickness on flight 
controls (ailerons, rudder, elevator), potentially having a negative 
impact on the flutter characteristics of the airplane. We are issuing 
this AD to detect and correct paint thickness on flight controls, which 
could result in loss of control of the airplane due to flutter.

DATES: This AD is effective August 1, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of August 1, 
2012.

SUPPLEMENTARY INFORMATION:

Discussion

    We received reports of failure to inspect or document the paint 
thickness on flight controls (ailerons, rudder, elevator), potentially 
having a negative impact on the flutter characteristics of the 
airplane. Excessive paint thickness will affect the balance moment of 
the flight control surface. This condition, if not corrected, could 
result in loss of control of the airplane due to flutter.

Relevant Service Information

    We reviewed the following service information, which describes 
procedures for measuring the paint thickness on both sides of each 
flight control surface (ailerons, rudder, and elevator) and corrective 
actions if necessary. The customer bulletins also describe procedures 
for revising the AFM to advise the flightcrew to not exceed a certain 
altitude until corrective actions have been accomplished. Corrective 
actions include removing the flight control surface and rebalancing, 
stripping, repainting with an average thickness less than 5.0 mils, and 
sanding/buffing down to 5.0 mils or less and re-measuring thicknesses 
(not recommended on surfaces with averages exceeding 7.0 mils).

Airplane Flight Manual Supplement EASA-G550-2012-01, dated March 14, 
2012.

FAA's Determination

    We are issuing 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 these same type 
designs.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information described previously, except as discussed under 
``Differences Between the AD and the Service Information.'' This AD 
also requires sending the measurement and corrective action results to 
Gulfstream Aerospace Corporation.

Differences Between the AD and the Service Information

    The customer bulletins specified in paragraph (g) of this AD 
incorporate the airplane flight manual supplement (AFMS) as an on-
condition action. This AD requires operators to incorporate the AFMS 
within 20 days after the effective date of this AD. We have determined 
that this action is necessary to address the identified unsafe 
condition.
    Although the customer bulletins specified in paragraph (g) of this 
AD specify that operators may contact the manufacturer for disposition 
of certain repair conditions, this AD requires operators to repair 
those conditions in accordance with a method approved by the FAA.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule, because we 
received reports of failure to inspect or document the paint thickness 
on flight controls (ailerons, rudder, elevator), potentially having a 
negative impact on the flutter characteristics of the airplane. 
Excessive paint thickness will affect the balance moment of the flight 
control surface. This condition, if not corrected, could result in loss 
of control of the airplane due to flutter. Therefore, we find that 
notice and opportunity for prior public comment are impracticable and 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2012-0677 and 
Directorate Identifier 2012-NM-105-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
AD because of those comments.
    We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 33 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
a cost estimate for the on-condition actions specified in this AD.
    According to the manufacturer, the costs of this AD may be covered 
under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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, 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.
