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:

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. 
233B, dated March 8, 2007. For airplanes listed in TCDS A10SW, 
follow MHI MU-2 Service Bulletin No. 095/77-002, dated July 15, 
1998. This inspection requires the use of the following power 
assurance charts as applicable:
    (i) If you have not incorporated the AFM revisions required in 
paragraph (e)(2) of this AD: Use the power assurance charts 
referenced in Table 3 below; or
    (ii) If you have already incorporated the AFM revisions required 
in paragraph (e)(2) of this AD: Use the power assurance charts in 
section 6 of the revised AFMs required by paragraph (e)(2) of this 
AD.
