SUMMARY: We are adopting a new airworthiness dir ective (AD) for certain M7 Aerospace LP Models SA226-T, SA226-T(B), SA226-TC, and SA226- AT airplanes. This AD requires repetitive replacement and inspection of certa in elevator, rudder, aileron, and aileron-to-rudder interconnect primary control cables, and check ing and setting of flight cont rol cable tension. This AD was prompted by a report of a failure of a rudder control cable. We are issuing this AD to correct the unsafe condition on these products.

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 trai ning requiring applied full rudder to compensate for yaw effect. The airplane made an uneventfu l 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 alongsid e the camera system insta lled in the center of
the cabin. AD 87-02-02 (52 FR 2511, January 23, 1987) requires pe riodic inspection or replacement of all flight control cables on Models SA226 and SA227 airplanes. This ne w AD action requires repetitive replacement of specific flight c ontrol cables on affected serial nu mber Model SA226 airplanes that have been modified by installation of a camera syst em requiring rerouting of the affected flight
control cables. This condition, if not corrected, coul d result in loss of controlled f light due to failure of a rudder,
aileron and/or elev ator 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 pr imary control cables.

FAA's Determination

We are issuing this AD because we evaluated a ll 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 Justificat ion and Determination of the Effective Date

An unsafe condition exists that requires the i mmediate adoption of this AD. The FAA has found that the risk to the flying public justifies waivi ng 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 fi nd 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 requireme nts affecting flight safety and was not preceded by notice and an opportunity for public comment. Howe ver, we invite you to send any written data, views, or arguments about this AD. Send your co mments to an address listed under the ADDRESSES section. Include ''Docket No. FAA-2011-0832; Di rectorate Identifier 2011-CE-025-AD'' at the beginning of your comments. We specifically invi te 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 re ceive about this AD.

Costs of Compliance

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

Estimated Costs

Action Labor cost Parts cost Cost per product Cost on U.S. operators

Logbook check 1 work-hour X $85 per hour = $85 Not Applicable $85 $340

Inspection of all elevator, rudder, aileron, and
aileron-to-rudder interconnect primary
control cables 80 to 100 workhours X $85 per hour = $6,800 to $8,500 Not Applicable $6,800 to $8,500 $27,200 to $34,000

Replacement of all elevator, rudder, aileron,
and aileron-to-rudder interconnect primary
control cables 120 to 180 workhours X $85 per hour = $10,200 to $15,300 $18,800 $29,000 to $34,100 $116,000 to $136,400

Check (set) flight control
cable tension 20 to 25 workhours X $85 per hour = $1,700 to $2,125 Not Applicable $1,700 to $2,125 $6,800 to $8,500

3Authority f or 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 ai r 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 becau se it addresses an unsafe condition that is likely to exist or develop on products iden tified 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 th e various levels of
government.
For the reasons discussed a bove, I certify that this AD: (1) Is not a ''significant regulat ory action'' under Executive Order 12866, (2) Is not a ''significant rule'' under DOT Re gulatory 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.
