Airworthiness Directives; SOCATA Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for SOCATA Model TBM 700 airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 landing gear actuator rod and piston becoming unscrewed during operation and the landing gear actuator ball joint becoming uncrimped. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
DATES: We must receive comments on this proposed AD by January 21, 2014.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD No.: 2013-0227, dated September 23, 2013 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:
During maintenance check, possible unscrewing of rod and piston during operation was detected on a landing gear actuator. Investigation showed that this was likely caused by maintenance operation not conforming with the procedure described in the SOCATA maintenance manual.
Moreover, following in-service landing gear collapse, uncrimping of a right hand main landing gear (MLG) actuator ball joint was detected. Investigation revealed a manufacturing non-conformity of some actuator rod end assemblies.
These conditions, if not detected and corrected, could lead to MLG or nose landing gear (NLG) failure during landing or roll-out and consequent damage to the aeroplane and injury to occupants.
To address this potential unsafe condition, SOCATA issued Service Bulletin (SB) 70-197-32 to require a one-time inspection of the landing gear actuator piston/rod and SB 70-206-32 to require a one-time inspection of the landing gear actuator ball joint centering and, depending on findings, accomplishment of corrective actions.
SOCATA also developed modification 70-0334-32, embodied in production to secure rod/piston assembly through addition of a pin and to reduce retraction/extension indication failure through improvement of switch kinematics. These modified actuators have a new part number (P/N).
For the reasons described above, this AD requires a one-time inspection of the landing gear actuators piston/rod and ball joint centering and, depending on findings, accomplishment of applicable corrective actions.
You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-
2013-1019.
Relevant Service Information
SOCATA has issued DAHER-SOCATA Mandatory Service Bulletin SB 70-
197, dated April 2013; and DAHER-SOCATA Mandatory Service
Page 72835
Bulletin SB 70-206, dated April 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of the Proposed AD
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
Costs of Compliance
We estimate that this proposed AD will affect 495 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $84,150, or $170 per product.
In addition, we estimate that any necessary follow-on actions would take about 3 work-hours for each main landing gear and 3 work-hours for the nose landing gear, and require parts costing $100 for each rod and assembly. We have no way of determining the number of products that may need these actions.
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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
(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),
(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.

038-AD.
(a) Comments Due Date
We must receive comments by January 21, 2014.
(b) Affected ADs
None.
(c) Applicability
This AD applies to SOCATA TBM 700 airplanes, all serial numbers, certificated in any category.
(d) Subject
Air Transport Association of America (ATA) Code 32: Landing Gear.
(e) Reason
This AD was prompted by mandatory continuing airworthiness information (MCAI) originated 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 landing gear actuator rod and piston becoming unscrewed during operation and the landing gear actuator ball joint becoming uncrimped. We are issuing this AD to detect and correct discrepancies in the pistons/rods and the ball joint centering of the nose landing gear and main landing gear, which could result in landing gear failure and lead to damage of the airplane and occupant injury.
(f) Actions and Compliance
Unless already done, do the actions in paragraphs (f)(1) through (f)(4) of this AD on any airplane with the landing gear actuators part number (P/N) T700A3230050000, P/N T700A323005000000, or P/N T700A323005300000 installed:
(1) Within the next 8 months after the effective date of this AD, perform a detailed visual inspection (DVI) of the pistons and rods of the nose landing gear (NLG) and left hand (LH) and right hand (RH) main landing gear (MLG) actuators and measure the distance following the Accomplishment Instructions paragraphs (A)(1) through (A)(4) in DAHER-SOCATA Mandatory Service Bulletin SB 70-197, dated April 2013.
(2) Within the next 8 months after the effective date of this AD, perform a DVI of the ball joint centering of the NLG and LH and RH MLG actuators and measure the ball joint mismatch following the Accomplishment Instructions paragraphs (A) through (C) in DAHER-
SOCATA Mandatory Service Bulletin SB 70-206, dated April 2013.
(3) If during any inspection required in paragraphs (f)(1) or (f)(2) of this AD any discrepancy is found, before further flight, replace the affected actuator or rod end assembly if applicable with an airworthy part following the Accomplishment Instructions in paragraph (A)(5) through (A)(10) and paragraph (B) of DAHER-SOCATA Mandatory Service Bulletin SB 70-197, dated April 2013; and/or paragraph (D) and (E) of DAHER-SOCATA Mandatory Service Bulletin SB 70-206, dated April 2013.
(4) As of the effective date of this AD, do not install on any airplane a landing gear actuator P/N T700A3230050000, P/N T700A323005000000, or P/N T700A323005300000, unless it is found to be in compliance with the inspection requirements of paragraphs (f)(1) and (f)(2) of this AD. The landing gear actuator must be installed when doing these inspections.
(g) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
