SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Diamond Aircraft Industries GmbH Model DA 42 airplanes. The NPRM was published in the Federal Register on October 25, 2016 (81 FR 73360). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of E:\FR\FM\18JAR1.SGM 18JAR1 5360 Federal Register / Vol. 82, No. 11 / Wednesday, January 18, 2017 / Rules and Regulations another country. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2016–0156R1, dated November 23, 2016 (referred to after this as ‘‘the MCAI’’). The revised MCAI states: Two cases were reported of uncommanded engine in-flight shutdown (IFSD) on DA 42 aeroplanes. Subsequent investigations identified these occurrences were due to failure of the propeller regulating valve, caused by hot exhaust gases coming from fractured engine exhaust pipes. The initiating cracks on the exhaust pipes were not detected during previous inspections, since those exhaust pipes are equipped with nonremovable heat shields that do not allow inspection for certain sections of the exhaust pipe. This condition, if not corrected, could lead to further cases of IFSD or overheat damage, possibly resulting in a forced landing, with consequent damage to the aeroplane and injury to occupants. To address this potential unsafe condition, Diamond Aircraft Industries (DAI) developed an exhaust pipe without a directly attached integral heat shield that allows visual inspection over the entire exhaust pipe length. DAI issued Mandatory Service Bulletin (MSB) 42–120 and relevant Working Instruction (WI) WI–MSB 42–120, providing instructions to install the modified exhaust pipes. As an interim measure, an additional bracket was designed to hold the exhaust pipe in place in case of a pipe fracture. Consequently, EASA issued AD 2016– 0156, requiring replacement of the exhaust pipes with pipes having new design, and prohibiting (re)installation of the previous design pipes. Since that AD was issued, cracks were identified on modified exhaust pipes during an inspection. Furthermore, it was determined that the additional brackets provide a level of safety equivalent to the modified exhaust pipes. Consequently, DAI revised MSB 42–120, allowing installation of the additional brackets as alternative to the installation of the modified exhaust pipes. For the reasons described above, this AD is revised to reduce the Applicability, excluding certain post-mod aeroplanes, to allow only installation of the additional brackets as final solution and to remove the prohibition of reinstallation of unmodified exhaust pipes. mstockstill on DSK3G9T082PROD with RULES The MCAI can be found in the AD docket on the Internet at https:// www.regulations.gov/ document?D=FAA-2016-9317-0002. 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 relevant data and determined that air safety and the VerDate Sep<11>2014 16:39 Jan 17, 2017 Jkt 241001 public interest require adopting this AD as proposed except for the changes discussed above. We have determined that these changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 We reviewed Diamond Aircraft Industries GmbH Mandatory Service Bulletin MSB 42–120, dated June 24, 2016, Mandatory Service Bulletin MSB 42–120/1, dated November 10, 2016, and Work Instruction WI–MSB 42–120, dated June 24, 2016. In combination, this service information describes procedures for replacing the exhaust pipes with exhaust pipes having a new design. 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 AD. Costs of Compliance We estimate that this AD will affect 130 products of U.S. registry. We also estimate that it will take the following to comply with the requirements of this AD: It will take about 1 work-hour per product to comply with the installation of additional exhaust clamps required by this AD. The average labor rate is $85 per work-hour. Required parts will cost about $125 per product. Based on these figures, we estimate the cost of this AD on U.S. operators for the installation of additional exhaust clamps to be $27,300, or $210 per product. It will take about 4 work-hours per product to comply with the exhaust pipe replacement required by this AD. The average labor rate is $85 per workhour. Required parts will cost about $1,990 per product. Based on these figures, we estimate the cost of this AD on U.S. operators for the exhaust pipe replacement requirement to be $302,900, or $2,330 per product. 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. PO 00000 Frm 00026 Fmt 4700 Sfmt 4700 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.

SUPPLEMENTARY INFORMATION: Discussion We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Model A318 and A319 series airplanes, Model A320–211, –212, –214, –231, –232, and –233 airplanes, and Model A321 series airplanes. The SNPRM published in the Federal Register on June 28, 2016 (81 FR 41886) (‘‘the SNPRM’’). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on April 24, 2015 (80 FR 22939) (‘‘the NPRM’’). The NPRM proposed to require an inspection to identify the part number and serial number of the MLG sliding tubes installed on the airplane; an inspection of the axle on certain MLG sliding tubes for damage; and replacement of the sliding tube if necessary. The NPRM was prompted by a report of a rupture of a MLG sliding tube axle. The SNPRM proposed to remove certain service information that does not adequately address the identified unsafe condition and revise the compliance method. We are issuing this AD to detect and correct cracks in the axle and (partial) detachment of the axle and wheel from the sliding tube, which could result in failure of an MLG. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 Directive 2014–0058, dated March 11, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A318 and A319 series airplanes, Model A320–211, –212, –214, –231, –232, and –233 airplanes, and Model A321 series airplanes. The MCAI states: A main landing gear (MLG) sliding tube axle rupture occurred in service. Investigation of the affected part showed that this failure was due to an abnormal grinding operation during overhaul by a certain maintenance and repair organization located in Singapore. A population of MLG sliding tubes was subsequently identified whose axles may have been subject to this grinding operation, which may have resulted in areas of residual stress on the axles on the MLG sliding tubes. In addition, the MSN [manufacturer serial number] of the aeroplanes which are known to have had the affected parts installed have been identified. This condition, if not detected and corrected, could lead to cracks in the axle and (partial) detachment of axle and wheel from the sliding tube, possibly resulting in failure of a MLG with consequent damage to the aeroplane and injury to occupants. To address this potential unsafe condition, Messier-Bugatti-Dowty, the MLG gear manufacturer, issued Service Bulletin (SB) 200–32–313 and SB 201–32–62 [both dated February 25, 2013], providing inspection instructions and criteria for removal from service of the affected MLG sliding tubes. For the reasons described above, this [EASA] AD requires a one-time Special Detailed Inspection (SDI) of the axle on the affected MLG sliding tubes and, depending on findings, replacement of the MLG sliding tube. The SDI includes a detailed visual inspection of the chromium plate for damage, and a Barkhausen noise inspection of the sliding tube axles for damage.

Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM 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 this AD as proposed except for minor editorial changes.

Airworthiness Directives; Diamond Aircraft Industries GmbH 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Diamond Aircraft Industries GmbH Model DA 42 airplanes. 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 an uncommanded engine shutdown during flight due to 
failure of the propeller regulating valve caused by hot exhaust gases 
escaping from fractured engine exhaust pipes. We are issuing this AD to 
require actions to address the unsafe condition on these products.

DATES: This AD is effective February 22, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 22, 
2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Diamond Aircraft 
Industries GmbH Model DA 42 airplanes. The NPRM was published in the 
Federal Register on October 25, 2016 (81 FR 73360). The NPRM proposed 
to correct an unsafe condition for the specified products and was based 
on mandatory continuing airworthiness information (MCAI) originated by 
an aviation authority of

[[Page 5360]]

another country. The European Aviation Safety Agency (EASA), which is 
the Technical Agent for the Member States of the European Community, 
has issued AD No. 2016-0156R1, dated November 23, 2016 (referred to 
after this as ``the MCAI''). The revised MCAI states:

    Two cases were reported of uncommanded engine in-flight shutdown 
(IFSD) on DA 42 aeroplanes. Subsequent investigations identified 
these occurrences were due to failure of the propeller regulating 
valve, caused by hot exhaust gases coming from fractured engine 
exhaust pipes. The initiating cracks on the exhaust pipes were not 
detected during previous inspections, since those exhaust pipes are 
equipped with non-removable heat shields that do not allow 
inspection for certain sections of the exhaust pipe.
    This condition, if not corrected, could lead to further cases of 
IFSD or overheat damage, possibly resulting in a forced landing, 
with consequent damage to the aeroplane and injury to occupants.
    To address this potential unsafe condition, Diamond Aircraft 
Industries (DAI) developed an exhaust pipe without a directly 
attached integral heat shield that allows visual inspection over the 
entire exhaust pipe length. DAI issued Mandatory Service Bulletin 
(MSB) 42-120 and relevant Working Instruction (WI) WI-MSB 42-120, 
providing instructions to install the modified exhaust pipes. As an 
interim measure, an additional bracket was designed to hold the 
exhaust pipe in place in case of a pipe fracture.
    Consequently, EASA issued AD 2016-0156, requiring replacement of 
the exhaust pipes with pipes having new design, and prohibiting 
(re)installation of the previous design pipes.
    Since that AD was issued, cracks were identified on modified 
exhaust pipes during an inspection. Furthermore, it was determined 
that the additional brackets provide a level of safety equivalent to 
the modified exhaust pipes. Consequently, DAI revised MSB 42-120, 
allowing installation of the additional brackets as alternative to 
the installation of the modified exhaust pipes.
    For the reasons described above, this AD is revised to reduce 
the Applicability, excluding certain post-mod aeroplanes, to allow 
only installation of the additional brackets as final solution and 
to remove the prohibition of reinstallation of unmodified exhaust 
pipes.

The MCAI can be found in the AD docket on the Internet at https://www.regulations.gov/document?D=FAA-2016-9317-0002.

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 relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for the 
changes discussed above. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Diamond Aircraft Industries GmbH Mandatory Service 
Bulletin MSB 42-120, dated June 24, 2016, Mandatory Service Bulletin 
MSB 42-120/1, dated November 10, 2016, and Work Instruction WI-MSB 42-
120, dated June 24, 2016. In combination, this service information 
describes procedures for replacing the exhaust pipes with exhaust pipes 
having a new design. 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 AD.

Costs of Compliance

    We estimate that this AD will affect 130 products of U.S. registry. 
We also estimate that it will take the following to comply with the 
requirements of this AD:
    It will take about 1 work-hour per product to comply with the 
installation of additional exhaust clamps required by this AD. The 
average labor rate is $85 per work-hour. Required parts will cost about 
$125 per product.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators for the installation of additional exhaust clamps to be 
$27,300, or $210 per product.
    It will take about 4 work-hours per product to comply with the 
exhaust pipe replacement required by this AD. The average labor rate is 
$85 per work-hour. Required parts will cost about $1,990 per product.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators for the exhaust pipe replacement requirement to be $302,900, 
or $2,330 per product.

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.
