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.

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.
