Airworthiness Directives; M7 Aerospace LP Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
M7 Aerospace LP Models SA226-T, SA226-T(B), SA226-TC, and SA226-AT

    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of September 1, 
2011.

SUPPLEMENTARY INFORMATION:

Discussion

    We received a report of an M7 Aerospace LP Model SA226-T airplane 
experiencing loss of rudder control during single-engine occurrence 
training requiring applied full rudder to compensate for yaw effect. 
The airplane made an uneventful landing. A visual inspection found the 
left-hand primary rudder control cable had failed where the cable makes 
a 30 degree angle over a small pulley to accommodate re-routing of the 
control cable alongside the camera system installed in the center of 
the cabin.
    AD 87-02-02 (52 FR 2511, January 23, 1987) requires periodic 
inspection or replacement of all flight control cables on Models SA226 
and SA227 airplanes. This new AD action requires repetitive replacement 
of specific flight control cables on affected serial number Model SA226 
airplanes that have been modified by installation of a camera system 
requiring rerouting of the affected flight control cables.
    This condition, if not corrected, could result in loss of 
controlled flight due to failure of a rudder, aileron and/or elevator 
control cable.

Relevant Service Information

    We reviewed M7 Aerospace LP Service Bulletin 226-27-072, dated June 
27, 2011. The service information describes procedures for repetitive 
inspection and replacement of all elevator, rudder, aileron, and 
aileron-to-rudder interconnect primary control cables.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of these same type 
designs.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information described previously.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because if an 
elevator cable or another cable in certain situations breaks, the 
outcome can be catastrophic. Therefore, we find that notice and 
opportunity for prior public comment are impracticable and that good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2011-0832; Directorate 
Identifier 2011-CE-025-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 4 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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:

[[Page 50883]]

    (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.

    (2) If any deficiencies are found during the inspection required 
in paragraph (g)(1) of this AD, before further flight replace 
cables.

(h) Replacement

    (1) Replace primary control cables within the initial compliance 
times as listed below and repetitively thereafter at intervals not 
to exceed 3,500 hours time-in-service (TIS):
    (i) For cables with less than or equal to 3,500 hours TIS: 
Replace cables when the control cables reach a total of 3,500 hours 
TIS or 150 hours TIS after September 1, 2011 (the effective date of 
this AD), whichever occurs later.
    (ii) For cables with less than or equal to 5,000 hours TIS but 
greater than 3,500 hours TIS: Replace cables within 150 hours TIS 
after September 1, 2011 (the effective date of this AD).
