Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2015–23–12,
Amendment 39–18329 (80 FR 73096,
November 24, 2015) (‘‘AD 2015–23–
12’’). AD 2015–23–12 applied to all
´
ATR–GIE Avions de Transport Regional
Model ATR42 and ATR72 airplanes.
The NPRM published in the Federal
Register on May 31, 2017 (82 FR 24906).
The NPRM was prompted by a new
occurrence of a cracked MLG rear hinge
pin. The NPRM proposed to continue to
require identifying the serial number
and part number of the MLG rear hinge
VerDate Sep<11>2014
13:35 Aug 24, 2017
Jkt 241001
pins, and replacing pins or the MLG if
necessary. The NPRM also proposed to
require replacing certain additional
MLG hinge pins, and reducing certain
compliance times. We are issuing this
AD to detect and correct cracked rear
hinge pins, which could lead to MLG
structural failure, possibly resulting in
collapse of the MLG and consequent
injury to the occupants of the airplane.
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Union, has issued EASA Airworthiness
Directive 2016–0135, dated July 8, 2016
(referred to after this as the Mandatory
Continuing Airworthiness Information,
or ‘‘the MCAI’’), to correct an unsafe
condition for all ATR–GIE Avions de
´
Transport Regional Model ATR42 and
ATR72 airplanes. The MCAI states:
Prompted by cases of rupture of main
landing gear (MLG) rear hinge pin part
number (P/N) D61000 encountered in service
´ ´
in 1994 and 1996, DGAC [Direction Generale
de l’Aviation Civile] France issued AD 96–
131–064 (B) for ATR42 aeroplanes and AD
96–096–029 (B) for ATR72 aeroplanes to
require inspection and, depending on
findings, corrective action. Since those
[French] ADs were issued, new occurrences
of cracked rear hinge pin P/N [part number]
D61000 were reported on ATR72 MLG. The
result of subsequent investigation revealed
that the affected pins were subjected to a
non-detected thermal abuse done in
production during grinding process. Analysis
also showed that other MLG pin P/N’s could
be affected by the same production issue.
This condition, if not detected and
corrected, could lead to structural failure and
consequent collapse of the MLG, possibly
resulting in damage to the aeroplane and
injury to the occupants.
To address this potential unsafe condition,
EASA issued AD 2014–0074 [which
corresponds to FAA AD 2015–23–12] to
require inspection and, depending on
findings, replacement of affected pins.
After EASA AD 2014–0074 was issued, a
new occurrence was reported of a cracked
MLG hinge pin P/N D62055 installed on the
MLG Side Brace of an ATR42 aeroplane. This
new occurrence was also identified as related
to a non-detected thermal abuse done in
production during grinding process.
Prompted by this new occurrence, Messier
Bugatti Dowty (MBD) updated the list of
MLG hinge pins affected by this unsafe
condition by adding serial numbers (S/N),
which were previously not considered by
EASA AD 2014–0074. In addition, it was
determined that the compliance time for
replacement of pins with P/N D62055 must
be reduced. The six affected MBD Service
Bulletins (SB) were revised accordingly, and
six new ones were also published to address
this issue.
For the reasons described above, this
[EASA] AD retains the requirements of EASA
AD 2014–0074, which is superseded, but
addresses an expanded MLG hinge pin
population with appropriate compliance
time(s).

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 this AD
as proposed except for minor editorial
changes. We have determined that these
minor 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.

The actions required by AD 2015–23–
12, and retained in this AD take about
8 work-hours per product, at an average
labor rate of $85 per work-hour.
Required parts will cost about $16,000
per product. Based on these figures, the
estimated cost of the actions that are
required by AD 2015–23–12 is $16,680
per product.
We also estimate that it will take
about 8 work-hours per product to
comply with the basic requirements of
this AD. The average labor rate is $85
per work-hour. Required parts will cost
about $16,000 per product. Based on
these figures, we estimate the cost of
this AD on U.S. operators to be
$1,050,840, or $16,680 per product.
According to the manufacturer, some
of the costs of this AD may be covered
under warranty, thereby reducing the
cost impact on affected individuals. We
do not control warranty coverage for
affected individuals. As a result, we
have included all costs in our cost
estimate.
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 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.
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.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to transport category
airplanes to the Director of the System
Oversight Division.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2015-23-12, Amendment 39-18329 (80 FR 73096,
November 24, 2015) (``AD 2015-23-12''). AD 2015-23-12 applied to all
ATR-GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72
airplanes. The NPRM published in the Federal Register on May 31, 2017
(82 FR 24906). The NPRM was prompted by a new occurrence of a cracked
MLG rear hinge pin. The NPRM proposed to continue to require
identifying the serial number and part number of the MLG rear hinge
pins, and replacing pins or the MLG if necessary. The NPRM also
proposed to require replacing certain additional MLG hinge pins, and
reducing certain compliance times. We are issuing this AD to detect and
correct cracked rear hinge pins, which could lead to MLG structural
failure, possibly resulting in collapse of the MLG and consequent
injury to the occupants of the airplane.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2016-0135, dated July 8, 2016 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all ATR-GIE Avions de
Transport R[eacute]gional Model ATR42 and ATR72 airplanes. The MCAI
states:
Prompted by cases of rupture of main landing gear (MLG) rear
hinge pin part number (P/N) D61000 encountered in service in 1994
and 1996, DGAC [Direction G[eacute]n[eacute]rale de l'Aviation
Civile] France issued AD 96-131-064 (B) for ATR42 aeroplanes and AD
96-096-029 (B) for ATR72 aeroplanes to require inspection and,
depending on findings, corrective action. Since those [French] ADs
were issued, new occurrences of cracked rear hinge pin P/N [part
number] D61000 were reported on ATR72 MLG. The result of subsequent
investigation revealed that the affected pins were subjected to a
non-detected thermal abuse done in production during grinding
process. Analysis also showed that other MLG pin P/N's could be
affected by the same production issue.
This condition, if not detected and corrected, could lead to
structural failure and consequent collapse of the MLG, possibly
resulting in damage to the aeroplane and injury to the occupants.
To address this potential unsafe condition, EASA issued AD 2014-
0074 [which corresponds to FAA AD 2015-23-12] to require inspection
and, depending on findings, replacement of affected pins.
After EASA AD 2014-0074 was issued, a new occurrence was
reported of a cracked MLG hinge pin P/N D62055 installed on the MLG
Side Brace of an ATR42 aeroplane. This new occurrence was also
identified as related to a non-detected thermal abuse done in
production during grinding process.
Prompted by this new occurrence, Messier Bugatti Dowty (MBD)
updated the list of MLG hinge pins affected by this unsafe condition
by adding serial numbers (S/N), which were previously not considered
by EASA AD 2014-0074. In addition, it was determined that the
compliance time for replacement of pins with P/N D62055 must be
reduced. The six affected MBD Service Bulletins (SB) were revised
accordingly, and six new ones were also published to address this
issue.
For the reasons described above, this [EASA] AD retains the
requirements of EASA AD 2014-0074, which is superseded, but
addresses an expanded MLG hinge pin population with appropriate
compliance time(s).
You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0516.
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 this AD as proposed except for
minor editorial changes. We have determined that these minor 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
Messier-Bugatti-Dowty has issued the following service information,
which describes procedures for inspecting and replacing the MLG hinge
pin. These documents are distinct since they apply to different
airplane models and different MLG hinge pin part numbers.
Service Bulletin 631-32-213, Revision 2, dated March 15,
2016.

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.
Costs of Compliance
We estimate that this AD will affect 63 airplanes of U.S. registry.
[[Page 40481]]
The actions required by AD 2015-23-12, and retained in this AD take
about 8 work-hours per product, at an average labor rate of $85 per
work-hour. Required parts will cost about $16,000 per product. Based on
these figures, the estimated cost of the actions that are required by
AD 2015-23-12 is $16,680 per product.
We also estimate that it will take about 8 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $16,000 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $1,050,840, or $16,680 per product.
According to the manufacturer, some of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes to
the Director of the System Oversight Division.
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 that 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.
