Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for MD
Helicopters, Inc. (MDHI), Model 369A,
369D, 369E, 369FF, 369HE, 369HM,
369HS, 500N, and 600N helicopters
with a certain part-numbered main rotor
blade attach pin (pin) installed. This AD
requires ensuring the life limit of the
pin as listed in the Airworthiness
Limitations section of aircraft
maintenance records and Instructions
for Continued Airworthiness (ICA). If
the hours time-in-service (TIS) of a pin
is unknown, or if a pin has exceeded its
life limit, this AD requires removing the
affected pin from service. This AD was
prompted by a report from an operator
who purchased pins that did not have
life limit documentation. These actions
are intended to document the life limit
to prevent a pin remaining in service
beyond its fatigue life, which could
result in failure of a pin, failure of a
main rotor blade, and subsequent loss of
control of the helicopter.
DATES: This AD is effective March 31,
2016.

SUPPLEMENTARY INFORMATION:
Discussion
On September 2, 2015, at 80 FR
53028, 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 MDHI Model 369A,
369D, 369E, 369FF, 369HE, 369HM,
369HS, 500N, and 600N helicopters
with a pin part-number (P/N)
369X1004–5 installed. The NPRM
proposed to require determining the
number of hours TIS of each pin and
whether the aircraft maintenance
records contain a pin life limit. If the
hours TIS are unknown, NPRM
proposed to require removing the pin
from service. If the aircraft maintenance
records do not contain a pin life limit,
the NPRM proposed to require revising
the records and establishing a life limit
of 5,760 hours if the pin is installed on
a Model 369A, 369HE, 369HM, or
369HS helicopter, or 7,600 hours if the
pin is installed on a Model 369D, 369E,
369FF, 500N, or 600N helicopter. The
NPRM also proposed to require revising
the records to add a statement that if a
PO 00000
Frm 00001
Fmt 4700
Sfmt 4700
pin is interchanged between different
model helicopters, then its life limit
must be restricted to the lower life limit
even if it was originally installed on a
helicopter model with a higher life
limit. Lastly, the NPRM proposed to
prohibit installing a pin on any
helicopter before these proposed
requirements have been accomplished.
Aerometals produces pin P/N
369X1004–5 under a parts manufacturer
approval as a replacement pin for MDHI
P/N 369A1004–5. The NPRM was
prompted by a report from an operator
who purchased Aerometals’ pins P/N
369X1004–5 without life limit
documentation. The FAA inadvertently
approved the pins without a life limit in
the Airworthiness Limitations section
and without a restriction for parts that
are interchanged between models with
different life limits. A total of 5,133
affected pins were sold by Aerometals
without any indication that the parts
were life-limited. The proposed
requirements were intended to correct
the failure of these parts to have a
documented life limit to prevent a pin
remaining in service beyond its fatigue
life, which could result in failure of a
pin, failure of a main rotor blade, and
subsequent loss of control of the
helicopter.
Comments
After our NPRM (80 FR 53028,
September 2, 2015) was published, we
received a comment from one
commenter supporting the NPRM.
FAA’s Determination
We have reviewed the relevant
information and determined that an
unsafe condition exists and is likely to
exist or develop on other products of
these same type designs and that air
safety and the public interest require
adopting the AD requirements as
proposed.
Related Service Information
Aerometals has issued Aero–ICA–
1001 Supplemental Instructions for
Continued Airworthiness, Revision NC,
dated May 22, 2014, and Service
Bulletin Aero–SB–1103, dated July 2,
2014. The service bulletin specifies
determining whether the helicopter has
pins P/N 369X1004–5 installed and then
reviewing the aircraft maintenance
records to determine if the pins have a
life limit identified. If the life limit is
not the same as that listed in the ICA,
E:\FR\FM\25FER1.SGM
25FER1
9332
Federal Register / Vol. 81, No. 37 / Thursday, February 25, 2016 / Rules and Regulations
the service bulletin specifies revising
the life limit in the maintenance
records. The service bulletin states that
the pins were approved by the FAA as
parts manufacturer approval direct
replacement parts with the same life
limits as the parts they replace.
However, they were sold without an
FAA-approved supplemental ICA
containing an Airworthiness Limitations
Section specifically assigning these life
limits to the pins.
Costs of Compliance
We estimate that this AD will affect
118 helicopters of U.S. Registry. We
estimate that operators may incur the
following costs in order to comply with
this AD. Labor costs are estimated at $85
per work-hour. We estimate 1/2 workhour to inspect and record any update
for a total of $42.50 per helicopter and
$5,015 for the U.S. fleet. If required, we
estimate 1 work-hour per helicopter to
replace 10 pins because each blade has
2 pins and each helicopter has 5 blades.
Required parts are $445 for each pin.
Based on these estimates, it will cost
$4,535 per helicopter to replace 10 pins
if the pins have exceeded their life limit.
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.

for satisfying certain inspection and
review responsibilities under § 1.42–
5(c)(2) for projects for which the
Department of Housing and Urban
Development (HUD) conducted physical
inspections.1 Notice 2012–18 also
requested comments on various issues
relating to § 1.42–5. The Treasury
Department and the IRS received
written and electronic comments in
response. After consideration of all of
the comments received, the Treasury
Department and the IRS are issuing
these final and temporary regulations.
This document also updates the
authority citation of 26 CFR part 1. The
Omnibus Budget Reconciliation Act of
1989 (Pub. L. 101–239) re-designated
section 42(m) of the Code as section
42(n). The updates in this document
reflect that re-designation.
General Overview
Section 42 provides rules for
determining the amount of the lowincome housing credit, which section 38
allows as a credit against income tax.
Section 42(a) provides that the amount
of the low-income housing credit for
any taxable year in the credit period is
an amount equal to the applicable
percentage of the qualified basis of each
qualified low-income building. Section
42(c)(2) defines a qualified low-income
building as any building that is part of
a qualified low-income housing project
at all times during the compliance
period (the period of 15 taxable years
beginning with the first taxable year of
the credit period).
Section 42(g)(1) defines a qualified
low-income housing project as any
project for residential rental property if
the project meets one of the following
tests, as elected by the taxpayer:
(A) At least 20 percent of the
residential units in the project are rentrestricted and occupied by individuals
whose income is 50 percent or less of
area median gross income; or
(B) At least 40 percent of the
residential units in the project are rentrestricted and occupied by individuals
whose income is 60 percent or less of
area median gross income.
In general, under section 42(i)(3)(A), a
low-income unit is a residential unit
that is rent-restricted and the occupants
of which meet the applicable income
limit elected by the taxpayer as
described in section 42(g)(1)(A) or (B).
1 Notice 2014–15, 2014–12 IRB 661, extended
permission through December 31, 2014, for State
and local housing credit agencies to use the
alternative method in Notice 2012–18.
PO 00000
Frm 00003
Fmt 4700
Sfmt 4700
9333
Under section 42(i)(3)(B)(i), a unit is
not treated as a low-income unit unless
it is suitable for occupancy and used
other than on a transient basis. Under
section 42(i)(3)(B)(ii), the suitability of a
unit for occupancy must be determined
under regulations prescribed by the
Secretary taking into account local
health, safety, and building codes.
Failure of one or more units to qualify
as low-income units may result in a
project’s ineligibility for the low-income
housing credit, reduction in the amount
of the credit, and/or recapture of
previously allowed credits.
Under section 42(m)(1), the owners of
an otherwise-qualifying building are not
entitled to low-income housing credits
that are allocated to the building unless,
among other requirements, the
allocation is pursuant to a qualified
allocation plan (QAP). A QAP provides
standards by which a State or local
housing credit agency or its Authorized
Delegate within the meaning of § 1.42–
5(f)(1) (‘‘Agency’’) will make these
allocations. A QAP also provides a
procedure that an Agency must follow
in monitoring for compliance with the
provisions of section 42. A plan fails to
be a QAP unless, in addition to other
requirements, it—
provides a procedure that the agency (or an
agent or other private contractor of such
agency) will follow in monitoring for
noncompliance with the provisions of
[section 42] and in notifying the Internal
Revenue Service of such noncompliance
which such agency becomes aware of and in
monitoring for noncompliance with
habitability standards through regular site
visits.
Section 42(m)(1)(B)(iii).
Section 1.42–5 (the compliancemonitoring regulations) describes some
of the provisions that must be part of
any QAP. As part of its compliancemonitoring responsibilities, an Agency
must perform physical inspections and
low-income certification review.
The compliance-monitoring
regulations specifically provide that, for
each low-income housing project, an
Agency must conduct on-site
inspections of all buildings by the end
of the second calendar year following
the year the last building in the project
is placed in service (the all-buildings
requirement). In addition, prior to the
amendments in this document, the
regulations provided that, for at least 20
percent of the project’s low-income
units (the 20-percent rule), the Agency
must both inspect the units and review
the low-income certifications, the
documentation supporting the
certifications, and the rent records for
the tenants in those same units (the
same-units requirement). The

Airworthiness Directives; MD Helicopters Inc., Helicopters
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for MD
Helicopters, Inc. (MDHI), Model 369A, 369D, 369E, 369FF, 369HE, 369HM,
369HS, 500N, and 600N helicopters with a certain part-numbered main
rotor blade attach pin (pin) installed. This AD requires ensuring the
life limit of the pin as listed in the Airworthiness Limitations
section of aircraft maintenance records and Instructions for Continued
Airworthiness (ICA). If the hours time-in-service (TIS) of a pin is
unknown, or if a pin has exceeded its life limit, this AD requires
removing the affected pin from service. This AD was prompted by a
report from an operator who purchased pins that did not have life limit
documentation. These actions are intended to document the life limit to
prevent a pin remaining in service beyond its fatigue life, which could
result in failure of a pin, failure of a main rotor blade, and
subsequent loss of control of the helicopter.

SUPPLEMENTARY INFORMATION:
Discussion
On September 2, 2015, at 80 FR 53028, 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 MDHI Model
369A, 369D, 369E, 369FF, 369HE, 369HM, 369HS, 500N, and 600N
helicopters with a pin part-number (P/N) 369X1004-5 installed. The NPRM
proposed to require determining the number of hours TIS of each pin and
whether the aircraft maintenance records contain a pin life limit. If
the hours TIS are unknown, NPRM proposed to require removing the pin
from service. If the aircraft maintenance records do not contain a pin
life limit, the NPRM proposed to require revising the records and
establishing a life limit of 5,760 hours if the pin is installed on a
Model 369A, 369HE, 369HM, or 369HS helicopter, or 7,600 hours if the
pin is installed on a Model 369D, 369E, 369FF, 500N, or 600N
helicopter. The NPRM also proposed to require revising the records to
add a statement that if a pin is interchanged between different model
helicopters, then its life limit must be restricted to the lower life
limit even if it was originally installed on a helicopter model with a
higher life limit. Lastly, the NPRM proposed to prohibit installing a
pin on any helicopter before these proposed requirements have been
accomplished.
Aerometals produces pin P/N 369X1004-5 under a parts manufacturer
approval as a replacement pin for MDHI P/N 369A1004-5. The NPRM was
prompted by a report from an operator who purchased Aerometals' pins P/
N 369X1004-5 without life limit documentation. The FAA inadvertently
approved the pins without a life limit in the Airworthiness Limitations
section and without a restriction for parts that are interchanged
between models with different life limits. A total of 5,133 affected
pins were sold by Aerometals without any indication that the parts were
life-limited. The proposed requirements were intended to correct the
failure of these parts to have a documented life limit to prevent a pin
remaining in service beyond its fatigue life, which could result in
failure of a pin, failure of a main rotor blade, and subsequent loss of
control of the helicopter.
Comments
After our NPRM (80 FR 53028, September 2, 2015) was published, we
received a comment from one commenter supporting the NPRM.
FAA's Determination
We have reviewed the relevant information and determined that an
unsafe condition exists and is likely to exist or develop on other
products of these same type designs and that air safety and the public
interest require adopting the AD requirements as proposed.
Related Service Information
Aerometals has issued Aero-ICA-1001 Supplemental Instructions for
Continued Airworthiness, Revision NC, dated May 22, 2014, and Service
Bulletin Aero-SB-1103, dated July 2, 2014. The service bulletin
specifies determining whether the helicopter has pins P/N 369X1004-5
installed and then reviewing the aircraft maintenance records to
determine if the pins have a life limit identified. If the life limit
is not the same as that listed in the ICA,
[[Page 9332]]
the service bulletin specifies revising the life limit in the
maintenance records. The service bulletin states that the pins were
approved by the FAA as parts manufacturer approval direct replacement
parts with the same life limits as the parts they replace. However,
they were sold without an FAA-approved supplemental ICA containing an
Airworthiness Limitations Section specifically assigning these life
limits to the pins.
Costs of Compliance
We estimate that this AD will affect 118 helicopters of U.S.
Registry. We estimate that operators may incur the following costs in
order to comply with this AD. Labor costs are estimated at $85 per
work-hour. We estimate 1/2 work-hour to inspect and record any update
for a total of $42.50 per helicopter and $5,015 for the U.S. fleet. If
required, we estimate 1 work-hour per helicopter to replace 10 pins
because each blade has 2 pins and each helicopter has 5 blades.
Required parts are $445 for each pin. Based on these estimates, it will
cost $4,535 per helicopter to replace 10 pins if the pins have exceeded
their life limit.
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
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.
