Model A119 and AW119 MKII Helicopters Federal Aviation Administration, DOT. ACTION: Final rule; request for comments. AGENCY: This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 2010–15–51, which was sent previously to all known U.S. owners and operators of Agusta S.p.A. (Agusta) Model A119 and AW119 MKII helicopters by individual letters. This AD requires, within 5 hours time-in-service (TIS), and thereafter at intervals not to exceed 50 hours TIS, removing the cover of each pilot and co-pilot control box assembly (control box) and inspecting each rotary variable differential transformer (RVDT) control gear locking pin (locking pin) for proper position. If a locking pin is recessed, extended, or missing, this AD requires replacing the control box before further flight. This amendment is prompted by a report that an RVDT locking pin that was installed on a Model AW119 MKII helicopter moved from its proper position, resulting in loss of connectivity of the pilot and co-pilot throttle controls. The actions specified by this AD are intended to prevent the RVDT locking pin from moving from its proper position, which could lead to loss of manual engine throttle control, and subsequent loss of control of the helicopter. DATES: Effective September 2, 2010, to all persons except those persons to erowe on DSK5CLS3C1PROD with RULES SUMMARY: VerDate Mar<15>2010 15:12 Aug 17, 2010 Jkt 220001 whom it was made immediately effective by Emergency AD 2010–15–51, issued on July 16, 2010, which contained the requirements of this amendment. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of September 2, 2010.

SUPPLEMENTARY INFORMATION: On July 16, 2010, we issued Emergency AD 2010–15–51 for the specified model helicopters, which requires, within 5 hours TIS, and thereafter at intervals not to exceed 50 hours TIS, removing the cover of the pilot and co-pilot control PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 50863 boxes and inspecting each RVDT locking pin for proper position. If a locking pin is recessed, extended, or missing, the AD requires replacing the control box before further flight. That action was prompted by a report that an RVDT locking pin that was installed on a Model AW119 MKII helicopter moved from its proper position, resulting in loss of connectivity of the pilot and copilot throttle controls. Investigation revealed that the pilot’s locking pin had moved from its proper position, which resulted in the loss of the co-pilot throttle control. This condition, if not detected and corrected, could result in loss of manual engine throttle control, and subsequent loss of control of the helicopter. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, notified us that an unsafe condition may exist on Agusta Model A119 and AW119 MKII helicopters. EASA advises of a nonconformity of certain control boxes, unseating of a locking pin, and loss of the pilot and copilot engine throttle synchronicity. EASA states this condition, if not detected and corrected, could lead to the loss of manual engine throttle control and consequent loss of control of the helicopter. Agusta has issued Alert Bollettino Tecnico No. 119–39, dated July 2, 2010 (ABT). The ABT describes procedures for inspecting the pilot and co-pilot control box for correct positioning of the locking pin. The ABT states that the investigation is still in progress to find a solution to the malfunction. The instructions in the ABT are prescribed as precautionary pending future corrective action. EASA classified this ABT as mandatory and issued Emergency AD 2010–0142–E, dated July 5, 2010, to ensure the continued airworthiness of these helicopters. This AD differs from EASA Emergency AD No. 2010–0142–E in that we use the term ‘‘hours time-in-service’’ rather than ‘‘flight hours.’’ Also, we clarify the inspection requirements and do not use the calendar date of August 31, 2010 as a required compliance time. These helicopter models are manufactured in Italy and are type certificated for operation in the United States under the provisions of 14 CFR 21.29 and the applicable bilateral agreement. Pursuant to the applicable bilateral agreement, EASA has kept the FAA informed of the situation described. We have examined the findings of EASA, reviewed all available information, and determined that AD action is necessary for products of these E:\FR\FM\18AUR1.SGM 18AUR1 erowe on DSK5CLS3C1PROD with RULES 50864 Federal Register / Vol. 75, No. 159 / Wednesday, August 18, 2010 / Rules and Regulations type designs that are certificated for operation in the United States. Since the unsafe condition described is likely to exist or develop on other Agusta Model A119 and AW119 MKII helicopters of the same type design, we issued Emergency AD 2010–15–51 to detect a missing or improperly fitted RVDT locking pin, which could lead to loss of manual engine throttle control, and subsequent loss of control of the helicopter. The AD requires, within 5 hours TIS, and thereafter at intervals not to exceed 50 hours TIS, removing the cover of the pilot and co-pilot control boxes and inspecting the locking pins for proper position. If the locking pin is recessed or extended in excess of 2.0 millimeters from the face of the pin bore, or missing, before further flight, replacing the control box with an airworthy control box that has been inspected in accordance with paragraph (a) of the AD is required. Replacing the control box does not constitute terminating action for the inspection requirements of the AD. The actions must be accomplished in accordance with specified portions of the ABT described previously. The short compliance time involved is required because the previously described critical unsafe condition can adversely affect the controllability of the helicopter. The actions previously described are required within short compliance times: 5 hours TIS and then at intervals not to exceed 50 hours TIS for the initial and repetitive inspections and before further flight for any required control box replacement; therefore, this AD must be issued immediately. Since it was found that immediate corrective action was required, notice and opportunity for prior public comment thereon were impracticable and contrary to the public interest, and good cause existed to make the AD effective immediately by individual letters issued on July 16, 2010 to all known U.S. owners and operators of Agusta Model A119 and AW119 MKII helicopters. These conditions still exist, and the AD is hereby published in the Federal Register as an amendment to 14 CFR 39.13 to make it effective to all persons. We estimate that this AD will affect 32 helicopters of U.S. registry. Each inspection of both control boxes will take 11⁄2 hours and each control box replacement will take approximately 8 work hours (2 per helicopter). The average labor rate is $85 per work hour. It will cost approximately $12,852 for a pilot control box and $11,768 for a copilot control box. Based on these figures, we estimate the total cost impact of the AD on U.S. operators to VerDate Mar<15>2010 15:12 Aug 17, 2010 Jkt 220001 be $835,440 ($26,108 per helicopter, assuming 1 inspection of each control box and replacing both control boxes on each helicopter).

Fmt 4700 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: ■ PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: We have 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 that the 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); and 3. 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. See the AD docket to examine the economic evaluation. Frm 00020 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 PO 00000 Authority for This Rulemaking Sfmt 4700 Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2.

ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for the products listed above. 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: SUMMARY: Due to high fuel pressure, caused by exceeding pressure in front of the mechanical fuel pump (e.g. due to an electrical fuel pump), in limited cases a deviation in the fuel supply could occur. This can result in exceeding of the fuel pressure and might cause engine malfunction and/or massive fuel leakage. We are issuing this AD to prevent the pump from causing excessive fuel pressure, which could result in engine malfunction or a massive fuel leak. These conditions could cause loss of control of the airplane or a fire. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective September 22, 2010. On September 22, 2010, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at Document Management Facility, U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC 20590.

PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 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 June 8, 2010 (75 FR 32315). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Due to high fuel pressure, caused by exceeding pressure in front of the mechanical fuel pump (e.g. due to an electrical fuel pump), in limited cases a deviation in the fuel supply could occur. This can result in exceeding of the fuel pressure and might cause engine malfunction and/or massive fuel leakage. Non-compliance with these instructions could result in engine damages, personal injuries or death. The MCAI requires replacing the affected fuel pumps with a different part number fuel pump. The MCAI applies to all versions of Bombardier-Rotax GmbH 912 A, 912 F, and 912 S series engines. Versions of the 912 F series and 912 S series engines are type certificated in the United States. However, the Model 912 A series engine installed in various aircraft does not have an engine type certificate; instead, the engine is part of the aircraft type design. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD.

Airworthiness Directives; Agusta S.p.A. Model A119 and AW119 MKII 
Helicopters

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This document publishes in the Federal Register an amendment 
adopting Airworthiness Directive (AD) 2010-15-51, which was sent 
previously to all known U.S. owners and operators of Agusta S.p.A. 
(Agusta) Model A119 and AW119 MKII helicopters by individual letters. 
This AD requires, within 5 hours time-in-service (TIS), and thereafter 
at intervals not to exceed 50 hours TIS, removing the cover of each 
pilot and co-pilot control box assembly (control box) and inspecting 
each rotary variable differential transformer (RVDT) control gear 
locking pin (locking pin) for proper position. If a locking pin is 
recessed, extended, or missing, this AD requires replacing the control 
box before further flight. This amendment is prompted by a report that 
an RVDT locking pin that was installed on a Model AW119 MKII helicopter 
moved from its proper position, resulting in loss of connectivity of 
the pilot and co-pilot throttle controls. The actions specified by this 
AD are intended to prevent the RVDT locking pin from moving from its 
proper position, which could lead to loss of manual engine throttle 
control, and subsequent loss of control of the helicopter.

DATES: Effective September 2, 2010, to all persons except those persons 
to whom it was made immediately effective by Emergency AD 2010-15-51, 
issued on July 16, 2010, which contained the requirements of this 
amendment.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of September 2, 2010.
    Comments for inclusion in the Rules Docket must be received on or 
before October 18, 2010.

SUPPLEMENTARY INFORMATION: On July 16, 2010, we issued Emergency AD 
2010-15-51 for the specified model helicopters, which requires, within 
5 hours TIS, and thereafter at intervals not to exceed 50 hours TIS, 
removing the cover of the pilot and co-pilot control boxes and 
inspecting each RVDT locking pin for proper position. If a locking pin 
is recessed, extended, or missing, the AD requires replacing the 
control box before further flight. That action was prompted by a report 
that an RVDT locking pin that was installed on a Model AW119 MKII 
helicopter moved from its proper position, resulting in loss of 
connectivity of the pilot and co-pilot throttle controls. Investigation 
revealed that the pilot's locking pin had moved from its proper 
position, which resulted in the loss of the co-pilot throttle control. 
This condition, if not detected and corrected, could result in loss of 
manual engine throttle control, and subsequent loss of control of the 
helicopter.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, notified us that 
an unsafe condition may exist on Agusta Model A119 and AW119 MKII 
helicopters. EASA advises of a nonconformity of certain control boxes, 
unseating of a locking pin, and loss of the pilot and co-pilot engine 
throttle synchronicity. EASA states this condition, if not detected and 
corrected, could lead to the loss of manual engine throttle control and 
consequent loss of control of the helicopter.
    Agusta has issued Alert Bollettino Tecnico No. 119-39, dated July 
2, 2010 (ABT). The ABT describes procedures for inspecting the pilot 
and co-pilot control box for correct positioning of the locking pin. 
The ABT states that the investigation is still in progress to find a 
solution to the malfunction. The instructions in the ABT are prescribed 
as precautionary pending future corrective action. EASA classified this 
ABT as mandatory and issued Emergency AD 2010-0142-E, dated July 5, 
2010, to ensure the continued airworthiness of these helicopters. This 
AD differs from EASA Emergency AD No. 2010-0142-E in that we use the 
term ``hours time-in-service'' rather than ``flight hours.'' Also, we 
clarify the inspection requirements and do not use the calendar date of 
August 31, 2010 as a required compliance time.
    These helicopter models are manufactured in Italy and are type 
certificated for operation in the United States under the provisions of 
14 CFR 21.29 and the applicable bilateral agreement. Pursuant to the 
applicable bilateral agreement, EASA has kept the FAA informed of the 
situation described. We have examined the findings of EASA, reviewed 
all available information, and determined that AD action is necessary 
for products of these

[[Page 50864]]

type designs that are certificated for operation in the United States.
    Since the unsafe condition described is likely to exist or develop 
on other Agusta Model A119 and AW119 MKII helicopters of the same type 
design, we issued Emergency AD 2010-15-51 to detect a missing or 
improperly fitted RVDT locking pin, which could lead to loss of manual 
engine throttle control, and subsequent loss of control of the 
helicopter. The AD requires, within 5 hours TIS, and thereafter at 
intervals not to exceed 50 hours TIS, removing the cover of the pilot 
and co-pilot control boxes and inspecting the locking pins for proper 
position. If the locking pin is recessed or extended in excess of 2.0 
millimeters from the face of the pin bore, or missing, before further 
flight, replacing the control box with an airworthy control box that 
has been inspected in accordance with paragraph (a) of the AD is 
required. Replacing the control box does not constitute terminating 
action for the inspection requirements of the AD. The actions must be 
accomplished in accordance with specified portions of the ABT described 
previously.
    The short compliance time involved is required because the 
previously described critical unsafe condition can adversely affect the 
controllability of the helicopter. The actions previously described are 
required within short compliance times: 5 hours TIS and then at 
intervals not to exceed 50 hours TIS for the initial and repetitive 
inspections and before further flight for any required control box 
replacement; therefore, this AD must be issued immediately.
    Since it was found that immediate corrective action was required, 
notice and opportunity for prior public comment thereon were 
impracticable and contrary to the public interest, and good cause 
existed to make the AD effective immediately by individual letters 
issued on July 16, 2010 to all known U.S. owners and operators of 
Agusta Model A119 and AW119 MKII helicopters. These conditions still 
exist, and the AD is hereby published in the Federal Register as an 
amendment to 14 CFR 39.13 to make it effective to all persons.
    We estimate that this AD will affect 32 helicopters of U.S. 
registry. Each inspection of both control boxes will take 1\1/2\ hours 
and each control box replacement will take approximately 8 work hours 
(2 per helicopter). The average labor rate is $85 per work hour. It 
will cost approximately $12,852 for a pilot control box and $11,768 for 
a co-pilot control box. Based on these figures, we estimate the total 
cost impact of the AD on U.S. operators to be $835,440 ($26,108 per 
helicopter, assuming 1 inspection of each control box and replacing 
both control boxes on each helicopter).

Comments Invited

    This AD is a final rule that involves requirements that affect 
flight safety and was not preceded by notice and an opportunity for 
public comment; however, we invite you to submit any written data, 
views, or arguments regarding this AD. Send your comments to an address 
listed under ADDRESSES. Include ``Docket No. FAA-2010-0806; Directorate 
Identifier 2010-SW-071-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of the AD. We will consider all 
comments received by the closing date and may amend the AD in light 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 
with FAA personnel concerning this AD. Using the search function of our 
docket web site, you can find and read the comments to any of our 
dockets, including the name of the individual who sent the comment. You 
may review the DOT's complete Privacy Act Statement in the Federal 
Register published on April 11, 2000 (65 FR 19477-78).

Regulatory Findings

    We have 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 that the 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); and
    3. 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. See the AD docket to examine the economic evaluation.

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.
