We also invite comments relating to the economic, environmental, energy, or federalism impacts that might result from adopting the proposals in this document. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit only one time. We will file in the docket all comments that we receive, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive. Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to remove AD 2010–19–51, Amendment 39–16523 (75 FR 71540, November 24, 2010) and add a new AD. AD 2010–19–51 applies to Bell Model 222, 222B, 222U, 230, and 430 helicopters and requires inspecting parts of the servo actuator for certain conditions and replacing any unairworthy parts before further flight. AD 2010–19–51 was prompted by a collective servo actuator malfunction due to a nonconforming grind relief on a separate piston rod and corrosion cracking at the threaded end of the output piston rod assembly. The actions of AD 2010–19–51 were intended to detect corrosion or a nonconforming piston rod that, if not corrected, could result in the failure of the piston rod, failure of the servo actuator, and subsequent loss of helicopter control. The NPRM was published in the Federal Register on August 20, 2013 (78 FR 51123). The NPRM proposed inspecting servo actuator, part number (P/N) 222–382–001–107, for pitting or penetration of the base metal of the piston rod. If the piston rod has pitting or any penetration of the base metal, the NPRM proposed replacing the servo actuator with servo actuator P/N 222– VerDate Sep<11>2014 16:44 Jun 15, 2015 Jkt 235001 382–001–111 or P/N 222–382–001– 111FM, before further flight. Thereafter, the NPRM proposed requiring overhauling servo actuator P/N 222– 382–001–111 or P/N 222–382–001– 111FM at intervals not to exceed 10 years or 10,000 hours TIS, whichever comes first. Comments After our NPRM (78 FR 51123, August 20, 2013) was published, we received comments from one commenter. Request Bell noted that the AD does not mandate replacement of servo actuator P/N 222–382–001–107 with servo actuator part number P/N 222–382–001– 111 if no pitting or penetration of the base metal is found during the inspection, and requested that we include the replacement provisions in Part 1 of Bell Alert Service Bulletin (ASB) 430–11–46, Revision A, dated June 22, 2012. We agree. In light of Bell’s comment, we have determined that our AD should retain all of the inspection requirements of AD 2010–19–51 (75 FR 71540, November 24, 2010) and also include compliance times for replacing servo actuator P/N 222–382–001–107 with servo actuator part number P/N 222– 382–001–111 or –111FM based upon the results of the inspection, as specified in Revision A of the ASB. We have changed the Required Actions accordingly and are consequently proposing this SNPRM. FAA’s Determination We are proposing this SNPRM because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of these same type designs. Certain changes described above expand the scope of the original NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on this SNPRM. Related Service Information Under 1 CFR Part 51 We reviewed Woodward HRT Service Bulletin 141600–67–02, dated August 18, 2010, which provides instructions for disassembling the servo actuator and for cleaning and inspecting the piston rod and nut. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this SNPRM. PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 34333 Other Related Service Information We also reviewed Bell ASB 222–11– 111 for Model 222 and 222B helicopters, ASB 222U–11–82 for Model 222U helicopters, ASB 230–11–43 for Model 230 helicopters, and ASB 430–11–46 for Model 430 helicopters, all Revision A and all dated June 22, 2012. The ASBs contain, and require compliance with, Woodward HRT Service Bulletin 141600–67–03, dated February 14, 2012, to upgrade the servo actuator by replacing the piston rod and then reidentifying the servo actuator dash number with ‘‘–111FM.’’ The compliance time for upgrading the servo actuator varies depending on the results of the inspections required by Woodward HRT Service Bulletin 141600–67–02, dated August 18, 2010. The Bell ASBs also provide an alternative inspection procedure for servo actuator P/N 222–382–001–107 that has not reached certain hours TIS and where the servo actuator cannot be upgraded. TCCA classified these ASBs as mandatory and issued AD No. CF– 2010–29R1, dated July 26, 2012, to ensure the continued airworthiness of these helicopters. Proposed Requirements of the SNPRM This proposed AD would require before further flight: • Disassembling each servo actuator. • Cleaning the piston rod and nut, and inspecting the grind relief configuration for the piston rod and nut. If the grind relief is unacceptable, replacing the piston rod and nut. • Using a 10× or higher magnifying glass, visually inspecting the nut for any corrosion or any damage to the threads, and replacing the nut if you find any corrosion or any damage to the threads. • Using a 10× or higher magnifying glass, visually inspecting the piston rod for any corrosion, lack of cadmium plate, or damage. • If there is any corrosion or lack of cadmium plate or damage in certain critical areas, replacing the servo actuator with P/N 222–382–001–111 or P/N 222–382–001–111FM before further flight. • If there is any corrosion or lack of cadmium plate in areas that are not critical areas, reworking the piston rod, inspecting for bare base metal, and reassembling the servo actuator. Replacing the servo actuator with P/N 222–382–001–111 or P/N 222–382–001– 111FM would be required within 1,200 hours time-in-service (TIS) or 1 year, whichever occurs first. • If there is any corrosion that is red or orange in color, magnetic particle inspecting the piston rod for a crack, E:\FR\FM\16JNP1.SGM 16JNP1 34334 Federal Register / Vol. 80, No. 115 / Tuesday, June 16, 2015 / Proposed Rules and replacing the servo actuator with P/ N 222–382–001–111 or P/N 222–382– 001–111FM before further flight if there is a crack or within 2,400 hours TIS or 2 years, whichever occurs first, if there is no crack. • If there is no corrosion, lack of cadmium plate, or damage, inspecting for bare base metal, and reassembling the servo actuator. Replacing the servo actuator with P/N 222–382–001–111 or P/N 222–382–001–111FM would be required within 3,000 hours TIS or 4 years, whichever occurs first. • Overhauling servo actuator P/N 222–382–001–111 or P/N 222–382–001– 111FM at intervals not to exceed 10 years or 10,000 hours TIS, whichever occurs first. Differences Between the Proposed AD and the TCCA AD The TCCA AD requires inspecting each servo actuator to determine the condition of the piston rod assembly no later than 5 hours upon receiving the original issue of its AD. This proposed AD would require inspecting each servo actuator to determine the condition of the piston rod assembly before further flight. asabaliauskas on DSK5VPTVN1PROD with PROPOSALS Costs of Compliance We estimate that this proposed AD would affect 146 helicopters of U.S. Registry and that labor costs average $85 a work-hour. Based on these estimates, we expect the following costs: • Inspecting a servo actuator would require 4 work-hours per actuator for a labor cost of $340. No parts would be needed for a total cost of $1,020 per helicopter and $148,920 for the U.S. fleet given 3 actuators per helicopter. • Replacing a servo actuator would require 8 work-hours for a labor cost of $680. Parts would cost $35,700 for a total cost of $36,380 per actuator. • Overhauling the servo actuator would require 8 work-hours for a labor cost of $680. Parts would cost $11,900 for a total cost of $12,580 per actuator. 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 VerDate Sep<11>2014 16:44 Jun 15, 2015 Jkt 235001 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Airworthiness Directives; Bell Helicopter Textron Canada 
Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening 
of comment period.

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) for Bell Helicopter Textron Canada (Bell) Model 222, 222B, 222U, 
230, and 430 helicopters, which proposed to require replacing certain 
servo actuators before further flight. The NPRM was prompted by a 
collective servo actuator malfunction. This action revises the NPRM by 
adding new actions. Since these actions impose an additional burden 
over that proposed in the NPRM, we are reopening the comment period to 
allow the public the chance to comment on these proposed changes.

DATES: We must receive comments on this SNPRM by August 17, 2015.

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to remove AD 2010-19-51, Amendment 39-16523 (75 FR 71540, 
November 24, 2010) and add a new AD. AD 2010-19-51 applies to Bell 
Model 222, 222B, 222U, 230, and 430 helicopters and requires inspecting 
parts of the servo actuator for certain conditions and replacing any 
unairworthy parts before further flight. AD 2010-19-51 was prompted by 
a collective servo actuator malfunction due to a nonconforming grind 
relief on a separate piston rod and corrosion cracking at the threaded 
end of the output piston rod assembly. The actions of AD 2010-19-51 
were intended to detect corrosion or a nonconforming piston rod that, 
if not corrected, could result in the failure of the piston rod, 
failure of the servo actuator, and subsequent loss of helicopter 
control.
    The NPRM was published in the Federal Register on August 20, 2013 
(78 FR 51123). The NPRM proposed inspecting servo actuator, part number 
(P/N) 222-382-001-107, for pitting or penetration of the base metal of 
the piston rod. If the piston rod has pitting or any penetration of the 
base metal, the NPRM proposed replacing the servo actuator with servo 
actuator P/N 222-382-001-111 or P/N 222-382-001-111FM, before further 
flight. Thereafter, the NPRM proposed requiring overhauling servo 
actuator P/N 222-382-001-111 or P/N 222-382-001-111FM at intervals not 
to exceed 10 years or 10,000 hours TIS, whichever comes first.

Comments

    After our NPRM (78 FR 51123, August 20, 2013) was published, we 
received comments from one commenter.

Request

    Bell noted that the AD does not mandate replacement of servo 
actuator P/N 222-382-001-107 with servo actuator part number P/N 222-
382-001-111 if no pitting or penetration of the base metal is found 
during the inspection, and requested that we include the replacement 
provisions in Part 1 of Bell Alert Service Bulletin (ASB) 430-11-46, 
Revision A, dated June 22, 2012.
    We agree. In light of Bell's comment, we have determined that our 
AD should retain all of the inspection requirements of AD 2010-19-51 
(75 FR 71540, November 24, 2010) and also include compliance times for 
replacing servo actuator P/N 222-382-001-107 with servo actuator part 
number P/N 222-382-001-111 or -111FM based upon the results of the 
inspection, as specified in Revision A of the ASB. We have changed the 
Required Actions accordingly and are consequently proposing this SNPRM.

FAA's Determination

    We are proposing this SNPRM because we evaluated all known relevant 
information and determined that an unsafe condition is likely to exist 
or develop on other products of these same type designs. Certain 
changes described above expand the scope of the original NPRM. As a 
result, we have determined that it is necessary to reopen the comment 
period to provide additional opportunity for the public to comment on 
this SNPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Woodward HRT Service Bulletin 141600-67-02, dated 
August 18, 2010, which provides instructions for disassembling the 
servo actuator and for cleaning and inspecting the piston rod and nut. 
This service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section of this SNPRM.

Other Related Service Information

    We also reviewed Bell ASB 222-11-111 for Model 222 and 222B 
helicopters, ASB 222U-11-82 for Model 222U helicopters, ASB 230-11-43 
for Model 230 helicopters, and ASB 430-11-46 for Model 430 helicopters, 
all Revision A and all dated June 22, 2012. The ASBs contain, and 
require compliance with, Woodward HRT Service Bulletin 141600-67-03, 
dated February 14, 2012, to upgrade the servo actuator by replacing the 
piston rod and then re-identifying the servo actuator dash number with 
``-111FM.'' The compliance time for upgrading the servo actuator varies 
depending on the results of the inspections required by Woodward HRT 
Service Bulletin 141600-67-02, dated August 18, 2010. The Bell ASBs 
also provide an alternative inspection procedure for servo actuator P/N 
222-382-001-107 that has not reached certain hours TIS and where the 
servo actuator cannot be upgraded. TCCA classified these ASBs as 
mandatory and issued AD No. CF-2010-29R1, dated July 26, 2012, to 
ensure the continued airworthiness of these helicopters.

Proposed Requirements of the SNPRM

    This proposed AD would require before further flight:
     Disassembling each servo actuator.
     Cleaning the piston rod and nut, and inspecting the grind 
relief configuration for the piston rod and nut. If the grind relief is 
unacceptable, replacing the piston rod and nut.
     Using a 10x or higher magnifying glass, visually 
inspecting the nut for any corrosion or any damage to the threads, and 
replacing the nut if you find any corrosion or any damage to the 
threads.
     Using a 10x or higher magnifying glass, visually 
inspecting the piston rod for any corrosion, lack of cadmium plate, or 
damage.
     If there is any corrosion or lack of cadmium plate or 
damage in certain critical areas, replacing the servo actuator with P/N 
222-382-001-111 or P/N 222-382-001-111FM before further flight.
     If there is any corrosion or lack of cadmium plate in 
areas that are not critical areas, reworking the piston rod, inspecting 
for bare base metal, and reassembling the servo actuator. Replacing the 
servo actuator with P/N 222-382-001-111 or P/N 222-382-001-111FM would 
be required within 1,200 hours time-in-service (TIS) or 1 year, 
whichever occurs first.
     If there is any corrosion that is red or orange in color, 
magnetic particle inspecting the piston rod for a crack,

[[Page 34334]]

and replacing the servo actuator with P/N 222-382-001-111 or P/N 222-
382-001-111FM before further flight if there is a crack or within 2,400 
hours TIS or 2 years, whichever occurs first, if there is no crack.
     If there is no corrosion, lack of cadmium plate, or 
damage, inspecting for bare base metal, and reassembling the servo 
actuator. Replacing the servo actuator with P/N 222-382-001-111 or P/N 
222-382-001-111FM would be required within 3,000 hours TIS or 4 years, 
whichever occurs first.
     Overhauling servo actuator P/N 222-382-001-111 or P/N 222-
382-001-111FM at intervals not to exceed 10 years or 10,000 hours TIS, 
whichever occurs first.

Differences Between the Proposed AD and the TCCA AD

    The TCCA AD requires inspecting each servo actuator to determine 
the condition of the piston rod assembly no later than 5 hours upon 
receiving the original issue of its AD. This proposed AD would require 
inspecting each servo actuator to determine the condition of the piston 
rod assembly before further flight.

Costs of Compliance

    We estimate that this proposed AD would affect 146 helicopters of 
U.S. Registry and that labor costs average $85 a work-hour. Based on 
these estimates, we expect the following costs:
     Inspecting a servo actuator would require 4 work-hours per 
actuator for a labor cost of $340. No parts would be needed for a total 
cost of $1,020 per helicopter and $148,920 for the U.S. fleet given 3 
actuators per helicopter.
     Replacing a servo actuator would require 8 work-hours for 
a labor cost of $680. Parts would cost $35,700 for a total cost of 
$36,380 per actuator.
     Overhauling the servo actuator would require 8 work-hours 
for a labor cost of $680. Parts would cost $11,900 for a total cost of 
$12,580 per actuator.

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.
