Airworthiness Directives; Mitsubishi Heavy Industries, Ltd.
Various Models MU-2B Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) to
supersede Airworthiness Directive (AD) 2006-17-01, AD 2006-15-07, AD
2000-02-25, and AD 97-25-02, which applies to certain Mitsubishi Heavy
Industries, Ltd. (MHI) various Models MU-2B airplanes. An FAA MU-2B
safety evaluation resulted in the standardization of the MU-2B specific
training and the FAA-accepted pilot operating checklists through a
special Federal aviation regulation (SFAR). MHI revised the airplane
flight manuals (AFMs) to align them with the information in that
training and the checklists. In addition, incorporating all AFM
revisions up to and including this latest AFM revision will incorporate
all AFM compliance actions required by the four above-mentioned ADs.
This AD would retain from AD 2006-17-01 the inspection of the engine
torque indication system and possible recalibration of the torque
pressure transducers and would require incorporating all revisions up
to and including the latest revisions of the AFM. We are issuing this
AD to correct inconsistencies in critical operating procedures between
the MU-2B specific training, the FAA-accepted pilot operating
checklists, and the AFMs, which, if not corrected, could result in the
pilot inadvertently taking inappropriate actions in critical operating
conditions.

DATES: This AD becomes effective on July 22, 2010.
On July 22, 2010, the Director of the Federal Register approved the
incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION:

Discussion

This AD results from inconsistencies in critical operating
procedures between the MU-2B specific training, the FAA-accepted pilot
operating checklists, and the AFMs. In 2005, the FAA, Aircraft
Certification Service and Flight Standards Service, conducted an MU-2B
safety evaluation. The FAA found that MU-2B specific training was not
required for all operators and, when provided, was not standardized.
The safety evaluation also revealed that many FAA-accepted pilot
operating checklists used by operators and trainers at the time of the
evaluation had no regulatory basis and were locally produced. This
resulted in a lack of standardization for normal, abnormal, and
emergency flight operations.
In 2008, the FAA issued SFAR No. 108, Mitsubishi MU-2B Series
Airplane Special Training, Experience, and Operating Requirements. This
SFAR requires standardization for critical operating procedures in
training and in the FAA-accepted pilot operating checklists. MHI
revised the AFMs to align them with the information in the current
SFAR. The FAA requested Mitsubishi Heavy Industries, Ltd. make changes
to the AFM for each model approved under Type Certificate Data Sheets
(TCDS) A10SW and A2PC.
Incorporating all AFM revisions up to and including this latest AFM
revision will incorporate the AFM actions in other ADs, as follows:
AD 97-25-02, Amendment 39-10225 (62 FR 63830, December 3,
1997), requires revising the Limitations section of the airplane AFM to
prohibit positioning the power levers below the flight idle stop while
the airplane is in flight.
AD 2000-02-25, Amendment 39-11543 (65 FR 5422, February 4,
2000), requires revising the AFM to include requirements for activating
the airframe pneumatic deicing boots.
AD 2006-15-07, Amendment 39-14687 (71 FR 41116, July 20,
2006), requires revising the Limitations section of the AFM to prevent
improper rigging of the propeller feathering linkage.
AD 2006-17-01, Amendment 39-14722 (71 FR 47697, August 18,
2006), requires inspecting the engine torque indication system,
recalibrating the torque pressure transducers as required, and revising
the Limitations section of the AFM to include power assurance charts.
The one-time inspection and possible recalibration are not part of the
AFM revisions.
We are issuing this AD to correct inconsistencies in critical
operating procedures between the MU-2B specific training, the FAA-
accepted pilot operating checklists, and the AFMs, which, if not
corrected, could result in the pilot inadvertently taking inappropriate
actions in critical operating conditions.

Comments

We provided the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
and FAA's response to each comment:

Comment Issue No. 1: This Failure Could Lead to Loss of Control

Ralph M. Sorrells, Mitsubishi Heavy Industries America, Inc.,
Patrick E. Cannon, Turbine Aircraft Services, Inc., and Earle P. Martin
III, Mid-Coast Air Charter, Inc., comment on the Summary, Discussion,
and Unsafe Condition sections of the proposed AD. The commenters oppose
the wording used in the notice of proposed rulemaking (NPRM) that says
the unsafe condition, if left uncorrected, could result in loss of
control. Two of the commenters suggest this is an ``administrative'' AD
and we should not use ``loss of control'' as a justification. One
commenter suggests changing the justification to ``improve safety'' in
lieu of ``loss of control.''
We agree with the commenters that the wording ``loss of control''
used throughout the NPRM does not accurately reflect the justification
for this AD. We are changing the wording to the following in the
Summary, Discussion, and Unsafe Condition sections of the NPRM: ``We
are issuing this AD to correct inconsistencies in critical operating
procedures between the MU-2B specific training, the FAA-accepted pilot
operating checklists, and the AFMs, which, if not corrected, could
result in the pilot inadvertently taking inappropriate actions in
critical operating conditions.''

[[Page 34350]]

Comment Issue No. 2: Special Federal Aviation Regulation (SFAR)-108

Ralph M. Sorrells, Mitsubishi Heavy Industries America, Inc.,
states the current SFAR-108 mandates standardized training, the latest
revision of the AFM, and the use of standardized checklists. The SFAR
requirements have eliminated the ``inconsistencies'' as stated in the
NPRM; and the SFAR standardized FAA-accepted checklists, eliminating
the inconsistencies in the checklists; therefore, no unsafe condition
exists. We infer from this comment the commenter feels this AD action
is unnecessary. The FAA partially agrees with these comments.
We agree with the commenter that the SFAR-108 is the current
regulatory standard to follow, when inconsistencies exist between the
SFAR requirements and the approved AFM. However, we disagree with the
commenter that the inconsistencies have been eliminated. The SFAR
mandated the appropriate AFM for each model; however, it did not
specify an AFM revision level. Owners could currently be using a
version of the AFM that is not consistent with the FAA-accepted
checklists required by the SFAR. The intent of this NPRM is to mandate
the latest AFM revision level. To clarify the intent of the wording
``FAA-accepted checklists'' used in the NPRM, we are changing the first
paragraph of the Discussion section to read: ``* * * the safety
evaluation also revealed that many FAA-accepted pilot operating
checklists used by operators and trainers at the time of the evaluation
had no regulatory basis * * *''

Comment Issue No. 3: Current Applicable Service Bulletin for the
Compliance Section, Paragraph 2(e)(1)

Ralph M. Sorrells, Mitsubishi Heavy Industries America, Inc.,
states that the NPRM does not reference the latest revision to the
service bulletin in the Compliance section, paragraph 2(e)(1). He
suggests revising the Compliance section, paragraph 2(e)(1), to
reference MHI MU-2 Service Bulletin No. 233B, dated March 8, 2007, as
the applicable service bulletin for TCDS A2PC model airplanes.
The FAA partially agrees with this comment. We agree that
inspecting the engine torque indication system and recalibrating the
torque pressure transducers following MHI MU-2 Service Bulletin No.
233B, dated March 8, 2007, will comply with the requirements of the AD.
However, we disagree with requiring the actions following MHI MU-2
Service Bulletin No. 233B, dated March 8, 2007. The actions to inspect
the engine torque indication system and recalibrate the torque pressure
transducers are retained from AD 2006-17-01, issued in 2006, and doing
the actions following MHI MU-2 Service Bulletin No. 233A, dated January
14, 1999, still complies with the intent of AD 2006-17-01. We will
retain inspecting the engine torque indication system and recalibrating
the torque pressure transducers following MHI MU-2 Service Bulletin No.
233A, dated January 14, 1999, but add language allowing the use of MHI
MU-2 Service Bulletin No. 233B, dated March 8, 2007, to comply with the
requirements of this final rule AD action.

Comment Issue No. 4: Reformat Table No. 1

Ralph M. Sorrells, Mitsubishi Heavy Industries America, Inc.,
comments that Table 1 of the NPRM in the Compliance section of the NPRM
should be revised to clarify which TCDS applies to each model. The
commenter also suggests we change Table 1 of the NPRM to show the
correct revision level for the Model MU-2B-35 (A2PC), which is revision
10 versus revision 9. Certain model airplanes (-25, -26, and -35) were
type certificated under both the A2PC and A10SW type certificates and
have separate AFMs.
The commenter states Table 1 of the NPRM appears confusing as to
which AFM applies to the models approved under both TCDS A2PC and
A10SW. Table 1 of the NPRM does not reference the reissued AFM date
that applies for TCDS A2PC models. The AFM for TCDS A10SW models are
not affected since the power assurance charts were included in the
reissued AFM and have not been revised.
The FAA agrees with the commenter and will revise Table 3 of the
final rule AD action to clarify the appropriate TCDS and identify the
correct AFM, revision level, and effective pages for the power
assurance charts for all models.

Comment Issue No. 5: Reformat Table No. 2

Ralph M. Sorrells, Mitsubishi Heavy Industries America, Inc.,
comments on the need to clarify the appropriate action to obtain the
AFM information for Models MU-2B-35 and MU-2B-36 type certificated
under TCDS A10SW.
The commenter suggests referencing ``MU-2B-35 Airplane Flight
Manual J Model, Document Number MR-0158-1'' as the approved data for
Model MU-2B-35. The commenter also states there has never been an A10SW
version of the MU-2B-36 so this item should be removed. The commenter
recommends changing the language for the Note associated with Table 2
in the NPRM to state, ``AFM revisions are not available for Model MU-
2B-35 under TCDS A10SW because the only Model MU-2B-35 airplane is no
longer in service and was subsequently removed from the registry.
Mitsubishi Heavy Industries, Ltd. has indicated they have no intention
of putting the MU-2B-35 model back in production. There are no other
serial numbers eligible for this model, foreign or domestic. This model
is still eligible under the type certificate, so if Mitsubishi Heavy
Industries, Ltd., does put this model back in production, contact them
for an FAA-approved AFM.''
The FAA partially agrees with the commenter. We agree that the
A10SW TCDS has been revised to show no serial numbers for -35 and -36
models. However, since the models are still part of the type
certificate, we disagree with removing those models from the AD. As
such, we are retaining Models -35 and -36 in the Applicability section
of this AD. Since no serial numbers for these model airplanes currently
exist, it would be impossible to comply with the actions of this AD for
those airplane models. We are removing NOTE 2 and NOTE 3 and removing
Models -35 and -36 from TABLE 4 of this final rule AD action.

Comment Issue No. 6: Suggest the Wording ``Current AFM Revision''

Patrick E. Cannon, Turbine Aircraft Services, Inc., suggests that
to avoid revising the AD to mandate each subsequent AFM revision, the
NPRM use the term ``current AFM revision'' to mandate incorporating
subsequent revisions to the AFMs.
The FAA does not agree. We do not have the legal authority to
reference documents that do not currently exist for the purpose of
addressing an unsafe condition through AD action. The FAA will consider
approval of future revisions through additional rulemaking should the
need arise or may consider allowing their use of future revisions
through approval of an alternative method of compliance (AMOC) if the
substantiating data supports the revised AFM.

Conclusion

We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
except for the changes previously discussed and minor editorial
corrections. We have determined that these minor corrections:

[[Page 34351]]

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.

Costs of Compliance

We estimate that this AD affects 355 airplanes.
We estimate the following costs to accomplish the engine torque
indication system inspection, including the recalibration and ground
check if needed.
This is a retained cost from AD 2006-17-01:

----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
5 work-hours x $85 = $425.................... Not applicable................. $425 $150,875
----------------------------------------------------------------------------------------------------------------

We estimate the following costs to do the AFM revisions:

----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85............. Not applicable................. $85 $30,175
----------------------------------------------------------------------------------------------------------------

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 AD.

Regulatory Findings

We have 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); and
3. 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 a summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``Docket
No. FAA-2009-1076; Directorate Identifier 2009-CE-019-AD'' in your
request.

Unsafe Condition

(d) This AD results from inconsistencies in critical operating
procedures between the MU-2B specific training, the FAA-accepted
pilot operating checklists, and the airplane flight manuals (AFM).
MHI revised the AFMs to align them with the information in that
training and the checklists. We are issuing this AD to correct
inconsistencies in critical operating procedures between the MU-2B
specific training, the FAA-accepted pilot operating checklists, and
the AFMs, which, if not corrected, could result in pilots
inadvertently taking inappropriate actions in critical operating
conditions.

Compliance

(e) Do the following unless already done:
(1) Within 100 hours time-in-service (TIS) after September 22,
2006 (the effective date retained from AD 2006-17-01), inspect the
engine torque indication system and, before further flight after the
inspection, recalibrate the torque pressure transducers as required.
For airplanes listed in TCDS A2PC, follow MHI MU-2 Service Bulletin
No. 233A, dated January 14, 1999 or MHI MU-2 Service Bulletin No.
