VerDate Sep<11>2014 14:13 Apr 08, 2016 Jkt 238001 On June 2, 2014, at 79 FR 31229, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to Airbus Helicopters (previously Eurocopter France) Model EC225LP, AS332C, AS332L, AS332L1, and AS332L2 helicopters with a TECALEMIT MGB hose installed. The NPRM proposed to require repetitively inspecting each hose installed in the MGB compartment and replacing the hose before further flight if a crack, cut, or other damage exists that allows you to see the metal braid underneath. If a crack, cut, or other damage exists on the right-hand hydraulic system that does not allow you to see the metal braid underneath, the NPRM proposed replacing the hose within 300 hours TIS. If a crack, cut, or other damage exists on the left-hand hydraulic system that does not allow you to see the metal braid underneath, the NPRM proposed replacing the hose within 600 hours TIS. The proposed requirements were intended to prevent failure of a hose, which could result in loss of the hydraulic system and consequently, loss of helicopter control. The NPRM was prompted by AD No. 2013–0069, dated March 18, 2013, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Eurocopter (now Airbus Helicopters) Model AS332C, AS332C1, AS332L, AS332L1, AS332L2, and EC225LP helicopters. EASA advises that in-flight losses of hydraulic pressure were reported on these helicopters because of ‘‘significant’’ tears on the protection sheath of MGB hydraulic flexible ‘‘pipes’’ manufactured by TECALEMIT. This condition could lead to simultaneous left-hand and righthand hydraulic system leakage, loss of the hydraulic system, and consequently, loss of helicopter control could occur, EASA advises. The NPRM incorrectly stated that the Model AS332C1 helicopter did not have an FAA type certificate. We plan additional rulemaking to supersede this AD to include the Model AS332C1 helicopter. PO 00000 Frm 00037 Fmt 4700 Sfmt 4700 21259 Comments After our NPRM (79 FR 31229, June 2, 2014) was published, we received comments from one commenter. Request Airbus Helicopters noted that the proposed AD does not mention Airbus Helicopters service information specifying installation of nonTECALEMIT hoses, which it considers terminating action for the repetitive inspections of the hoses. Airbus Helicopters requested that the AD reflect that action. We agree with the comment but disagree that a change to the AD is necessary. Because the AD is only applicable if a TECALEMIT hose is installed, replacing the hose as described by Airbus Helicopters in its comment would serve as ‘‘terminating action’’ for the required inspections. If a non-TECALEMIT hose is installed, the AD does not apply. Airbus Helicopters stated that the proposed AD would require that a damaged hose sheath on right-hand hydraulic system be replaced within 300 hours time-in-service (TIS) and a damaged hose sheath on the left-hand system be replaced within 600 hours TIS. Airbus Helicopters requested that we change these proposed requirements to replacing the hose within 300 hours TIS if the hose sheath is damaged on both the right- and left-hand system and replacing the hose within 600 hours TIS if the hose sheath is damaged on only one side. We do not agree. The righthand hose is subject to higher pressure and therefore we determined more stringent requirements for the righthand hose are necessary than for the left-hand hose. Lastly, Airbus Helicopters requested that we extend the repetitive inspection to every 1,200 hours TIS after the initial inspection at 110 hours TIS. When asked for additional information, Airbus Helicopters stated that no discrepancies have been found as a result of the inspections on its EC225 fleet, and that most of its AS332 fleet that are operating have complied with the service information. We disagree. Airbus Helicopters provided no support for its position that the hoses perform safely for 1,200 hours TIS after the initial inspection. Because the root cause of the cracking is unknown, we have determined that inspecting the hoses every 110 hours TIS is necessary. FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral E:\FR\FM\11APR1.SGM 11APR1 21260 Federal Register / Vol. 81, No. 69 / Monday, April 11, 2016 / Rules and Regulations agreement with France, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA, reviewed the relevant information, considered the comments received, and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed. jstallworth on DSK7TPTVN1PROD with RULES Differences Between This AD and the EASA AD The EASA AD requires a one-time inspection, while this AD requires that the inspection of the hoses be repeated every 110 hours TIS. The EASA AD requires that if severe damage is found in a hose on the right-hand hydraulic system, then the hose be replaced before the next flight, while this AD requires this regardless of whether the hose is on the right-hand or left-hand hydraulic system. EASA has set some compliance times based on months. We set compliance times based only on hours TIS. Related Service Information Eurocopter issued Service Bulletin (SB) No. EC225–05–027, Revision 1, dated July 17, 2013, for Model EC225LP helicopters and SB No. AS332–05.00.92, Revision 1, dated July 17, 2013, for Model AS332C, AS332C1, AS332L, AS332L1, AS332L2 and military Model AS332B, AS332B1, AS332F1, AS332M and AS332M1 helicopters. The SBs state Eurocopter received a report concerning the loss of pressure in the left hand hydraulic system in-flight. Hydraulic fluid was found in the cabin, though the flight was completed without further incident. An examination of the hydraulic system showed that the hose located between the forward servocontrol and the hydraulic manifold had burst. Further investigations have shown corrosion on the metal braid located under the fire-resistant sheath of hoses manufactured by TECALEMIT. The corrosion may be caused by the deterioration or gaping of the fireresistant sheath at the hose ends, enabling humidity to enter between the sheath and the metal braid. As a result, SB No. EC225–05–027 and SB No. AS332–05.00.92 call for inspecting each hose for a notch, tear, crack, or scuff mark, and replacing any damaged hose. Costs of Compliance We estimate that this AD affects 19 helicopters of U.S. Registry and that labor costs average $85 a work-hour. VerDate Sep<11>2014 14:13 Apr 08, 2016 Jkt 238001 Based on these estimates, we expect the following costs: • Inspecting the hoses installed in a MGB compartment requires 1.5 workhours for a labor cost of about $128 per helicopter, $2,432 for the U.S. fleet. • Replacing a hose requires 2.5 workhours for a labor cost of about $213. Parts cost $2,000 for a total cost of $2,213 per helicopter. 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 helicopters 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.

Models PA– 28–161, PA–28–181, and PA–28R–201 airplanes. AD 2015–20–13 required inspecting the right wing rib at wing station 140.09 for cracks and taking necessary corrective action. AD 2015– 20–13 resulted from a report from Piper Aircraft, Inc. of a production quality control problem on certain Models PA– 28–161, PA–28–181, and PA–28R–201 airplanes. A change in production tooling and processes caused cracks to form along the edge of rib stiffening beads during manufacture. These cracks cause reduced structural integrity of the wing, which resulted in the inability of the wing rib to carry ultimate load. We issued AD 2015–20–13 to detect and correct cracks in the wing rib, which if not corrected, could result in reduced structural integrity of the wing with consequent loss of control. Actions Since AD 2015–20–13 Was Issued Since we issued AD 2015–20–13, we received reports that operators in the field found the same cracks in airplanes outside the original applicability.

SUPPLEMENTARY INFORMATION:

Discussion

    On June 2, 2014, at 79 FR 31229, the Federal Register published our 
notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR 
part 39 by adding an AD that would apply to Airbus Helicopters 
(previously Eurocopter France) Model EC225LP, AS332C, AS332L, AS332L1, 
and AS332L2 helicopters with a TECALEMIT MGB hose installed.
    The NPRM proposed to require repetitively inspecting each hose 
installed in the MGB compartment and replacing the hose before further 
flight if a crack, cut, or other damage exists that allows you to see 
the metal braid underneath. If a crack, cut, or other damage exists on 
the right-hand hydraulic system that does not allow you to see the 
metal braid underneath, the NPRM proposed replacing the hose within 300 
hours TIS. If a crack, cut, or other damage exists on the left-hand 
hydraulic system that does not allow you to see the metal braid 
underneath, the NPRM proposed replacing the hose within 600 hours TIS. 
The proposed requirements were intended to prevent failure of a hose, 
which could result in loss of the hydraulic system and consequently, 
loss of helicopter control.
    The NPRM was prompted by AD No. 2013-0069, dated March 18, 2013, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union, to correct an unsafe condition for Eurocopter (now 
Airbus Helicopters) Model AS332C, AS332C1, AS332L, AS332L1, AS332L2, 
and EC225LP helicopters. EASA advises that in-flight losses of 
hydraulic pressure were reported on these helicopters because of 
``significant'' tears on the protection sheath of MGB hydraulic 
flexible ``pipes'' manufactured by TECALEMIT. This condition could lead 
to simultaneous left-hand and right-hand hydraulic system leakage, loss 
of the hydraulic system, and consequently, loss of helicopter control 
could occur, EASA advises.
    The NPRM incorrectly stated that the Model AS332C1 helicopter did 
not have an FAA type certificate. We plan additional rulemaking to 
supersede this AD to include the Model AS332C1 helicopter.

Comments

    After our NPRM (79 FR 31229, June 2, 2014) was published, we 
received comments from one commenter.

Request

    Airbus Helicopters noted that the proposed AD does not mention 
Airbus Helicopters service information specifying installation of non-
TECALEMIT hoses, which it considers terminating action for the 
repetitive inspections of the hoses. Airbus Helicopters requested that 
the AD reflect that action. We agree with the comment but disagree that 
a change to the AD is necessary. Because the AD is only applicable if a 
TECALEMIT hose is installed, replacing the hose as described by Airbus 
Helicopters in its comment would serve as ``terminating action'' for 
the required inspections. If a non-TECALEMIT hose is installed, the AD 
does not apply.
    Airbus Helicopters stated that the proposed AD would require that a 
damaged hose sheath on right-hand hydraulic system be replaced within 
300 hours time-in-service (TIS) and a damaged hose sheath on the left-
hand system be replaced within 600 hours TIS. Airbus Helicopters 
requested that we change these proposed requirements to replacing the 
hose within 300 hours TIS if the hose sheath is damaged on both the 
right- and left-hand system and replacing the hose within 600 hours TIS 
if the hose sheath is damaged on only one side. We do not agree. The 
right-hand hose is subject to higher pressure and therefore we 
determined more stringent requirements for the right-hand hose are 
necessary than for the left-hand hose.
    Lastly, Airbus Helicopters requested that we extend the repetitive 
inspection to every 1,200 hours TIS after the initial inspection at 110 
hours TIS. When asked for additional information, Airbus Helicopters 
stated that no discrepancies have been found as a result of the 
inspections on its EC225 fleet, and that most of its AS332 fleet that 
are operating have complied with the service information. We disagree. 
Airbus Helicopters provided no support for its position that the hoses 
perform safely for 1,200 hours TIS after the initial inspection. 
Because the root cause of the cracking is unknown, we have determined 
that inspecting the hoses every 110 hours TIS is necessary.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral

agreement with France, EASA, its technical representative, has notified 
us of the unsafe condition described in the EASA AD. We are issuing 
this AD because we evaluated all information provided by EASA, reviewed 
the relevant information, considered the comments received, and 
determined the unsafe condition exists and is likely to exist or 
develop on other helicopters of these same type designs and that air 
safety and the public interest require adopting the AD requirements as 
proposed.

Differences Between This AD and the EASA AD

    The EASA AD requires a one-time inspection, while this AD requires 
that the inspection of the hoses be repeated every 110 hours TIS. The 
EASA AD requires that if severe damage is found in a hose on the right-
hand hydraulic system, then the hose be replaced before the next 
flight, while this AD requires this regardless of whether the hose is 
on the right-hand or left-hand hydraulic system. EASA has set some 
compliance times based on months. We set compliance times based only on 
hours TIS.

Related Service Information

    Eurocopter issued Service Bulletin (SB) No. EC225-05-027, Revision 
1, dated July 17, 2013, for Model EC225LP helicopters and SB No. AS332-
05.00.92, Revision 1, dated July 17, 2013, for Model AS332C, AS332C1, 
AS332L, AS332L1, AS332L2 and military Model AS332B, AS332B1, AS332F1, 
AS332M and AS332M1 helicopters. The SBs state Eurocopter received a 
report concerning the loss of pressure in the left hand hydraulic 
system in-flight. Hydraulic fluid was found in the cabin, though the 
flight was completed without further incident. An examination of the 
hydraulic system showed that the hose located between the forward 
servo-control and the hydraulic manifold had burst. Further 
investigations have shown corrosion on the metal braid located under 
the fire-resistant sheath of hoses manufactured by TECALEMIT. The 
corrosion may be caused by the deterioration or gaping of the fire-
resistant sheath at the hose ends, enabling humidity to enter between 
the sheath and the metal braid. As a result, SB No. EC225-05-027 and SB 
No. AS332-05.00.92 call for inspecting each hose for a notch, tear, 
crack, or scuff mark, and replacing any damaged hose.

Costs of Compliance

    We estimate that this AD affects 19 helicopters of U.S. Registry 
and that labor costs average $85 a work-hour. Based on these estimates, 
we expect the following costs:
     Inspecting the hoses installed in a MGB compartment 
requires 1.5 work-hours for a labor cost of about $128 per helicopter, 
$2,432 for the U.S. fleet.
     Replacing a hose requires 2.5 work-hours for a labor cost 
of about $213. Parts cost $2,000 for a total cost of $2,213 per 
helicopter.

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 helicopters 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.
