Administration (FAA), DOT.
ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for certain
The Boeing Company Model MD–11
and MD–11F airplanes. This AD was
prompted by a report that the rub strips
attached to the horizontal stabilizer
front spar access door location were
manufactured improperly using
anodized aluminum. This AD requires
replacing the anodized rub strips with
new alodined rub strips to prevent
inadequate electrical bonding between
the rub strips and the fuel access door,
which can contribute to possible
ignition of flammable fuel vapor in the
tail fuel tank as a result of a lightning
strike. We are issuing this AD to correct
the unsafe condition on these products.
DATES: This AD is effective January 17,
2012.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of January 17, 2012.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on June 30, 2011 (76 FR 38332).
That NPRM proposed to require
replacing the anodized rub strips of the
tail fuel tank access door with new
alodined rub strips.
Revisions to AD Language
In the NPRM (76 FR 38332, June 30,
2011) we specified that this AD was
prompted by a report that the rub strips
of the tail fuel tank access door were
manufactured improperly. We are
revising the statement to more
accurately reflect the location of the rub
strips. We have revised the summary
section and paragraph (e) of this AD
accordingly.
Also, to more accurately describe the
rub strips, we have revised paragraph (g)
PO 00000
Frm 00001
Fmt 4700
Sfmt 4700
of this AD to state, ‘‘replace the
anodized rub strips with new alodined
rub strips.’’
Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comment
received on the proposal and the FAA’s
response to the comment.
Request To Revise Part Number
UPS requested that Boeing revise the
part number of the alodined rub strip
specified in Boeing Special Attention
Service Bulletin MD11–55–027, dated
March 17, 2011. UPS stated that the
existing anodized rub strip has the same
part number as the new alodined rub
strip, and this may cause confusion for
the operators. UPS stated that changing
the part number of the new alodined rub
strip would prevent an anodized rub
strip from being installed instead of the
required alodined rub strip.
We disagree with the commenter’s
request to revise the part number of the
alodined rub strip. Boeing has verified
that prior to issuance of Boeing Special
Attention Service Bulletin MD11–55–
027, dated March 17, 2011, two
alodined rub strips have been sold to
the MD–11 operators. The rub strips are
not part of the access door. They are
riveted to the horizontal stabilizer front
spar web and are not re-installable after
drilling out rivets during replacement.
Since only alodined rub strips are
available and since the anodized rub
strips are destroyed during removal,
reinstalling anodized rub strips is not
possible. We have determined that the
only airplanes with anodized rub strips
are the airplanes listed in the
Applicability section of this AD. No
change has been made to the AD in this
regard.
Conclusion
We reviewed the relevant data,
considered the comment received, and
determined that air safety and the
public interest require adopting the AD
as proposed.
Costs of Compliance
We estimate that this AD affects 120
airplanes of U.S. registry.
We estimate the following costs to
comply with this AD:

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.

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, 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.

ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for Piaggio
Aero Industries S.p.A. Model P–180
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 the
baggage door lockpins not engaging
properly and the baggage door open
light illuminating when the baggage
door is not open, which could lead to
the pilot disregarding a valid warning.
We are issuing this AD to require
actions to address the unsafe condition
on these products.
DATES: This AD is effective January 17,
2012.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of January 17, 2012.

SUPPLEMENTARY INFORMATION:
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on September 29, 2011 (76 FR
60396). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
One event of in-flight baggage door
opening occurred on an in-service aeroplane
due to a defective locking mechanism or
installation thereof; the BAG DOOR warning
light went on properly before the event, but
was ignored by the pilot, who misinterpreted
it as a false warning.
NOTE: false in-service BAG DOOR
warnings had occurred on other P.180
aeroplanes, and Piaggio Aero Industries (PAI)
had issued Service Bulletin (SB) No. 80–0223
revision 1 to improve the installation of the
baggage door warning microswitch and to
modify the locking mechanism if necessary.
This condition, if not detected and
corrected, could lead to in-flight detachment
of the door, which could hit and damage the
left propeller and/or the vertical or horizontal
stabilizer, possibly resulting in loss of control
of the aeroplane, or in injuries to persons or
damage to property on the ground.
This AD requires an inspection of the
locking mechanism of the baggage door and
its proper adjustment, in accordance with
PAI SB No. 80–0289 revision 1; if baggage
door lockpins do not reach the correct
engagement, or false BAG DOOR warnings
were reported by flight crew, this AD
requires also a modification of the door
mechanism in accordance with PAI SB No.
80–0223 revision 1.
Instances of the baggage door open light
illuminating have occurred when the
baggage door was not open. This
condition, if not corrected, could result
in the pilot disregarding a valid
warning. You may obtain further
information by examining the MCAI in
the AD docket.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM (76
PO 00000

Fmt 4700
Sfmt 4700

FR 60396, September 29, 2011) 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 the AD
as proposed.
Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have required different
actions in this AD from those in the
MCAI in order to follow FAA policies.
Any such differences are highlighted in
a note within the AD.
Costs of Compliance
We estimate that this AD will affect
102 products of U.S. registry. We also
estimate that it would take about 29
work-hours per product to comply with
the basic requirements of this AD. The
average labor rate is $85 per work-hour.
Required parts would cost about $4,482
per product.
Based on these figures, we estimate
the cost of the AD on U.S. operators to
be 708,594, or $6,947 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

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.
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, 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.
