Start Preamble

AGENCY:

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

ACTION:

Supplemental notice of proposed rulemaking (NPRM); reopening of the comment period.

SUMMARY:

We are revising an NPRM for SOCATA Model TBM 700 airplaness Start Printed Page 33209(type certificate previously held by EADS SOCATA) that was proposed to revise AD 2007-04-13. 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 cracks found on the main landing gear cylinders. This action revises the NPRM by including the actions against those airplanes that reach a certain number of landings after the effective date of the AD. We are proposing this supplemental NPRM (SNPRM) to correct the unsafe condition on these products. Since this action imposes an additional burden over that proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on this proposed change.

DATES:

We must receive comments on this proposed AD by July 27, 2015.

SUPPLEMENTARY INFORMATION:

Comments Invited

We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2015-2047; Directorate Identifier 2015-CE-013-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed 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 proposed AD.

The docket number and the directorate identifier of the NPRM (80 FR 8821, February 19, 2015) is Docket No. FAA-2006-26235; Directorate Identifier 2006-CE-065-AD. The NPRM docket number is different than the docket number of this SNPRM. The comment period for the NPRM closed on April 6, 2015; we received one comment in support of the NPRM.

Discussion

We proposed to amend 14 CFR part 39 with an NPRM for SOCATA Model TBM 700 airplanes (type certificate previously held by EADS SOCATA), which was published in the Federal Register on February 19, 2015 (80 FR 8821). The NPRM proposed to require actions intended to address the unsafe condition for the products listed above and was based on mandatory continuing airworthiness information (MCAI) originated by another country.

Since the NPRM was issued, we have determined that airplanes with MLG with forging body that had not reached 1,750 landings as of March 23, 2007 (the effective date of AD 2007-04-13) were not affected by the AD. This is not the intent and allows airplanes to fly indefinitely with the unsafe condition. This supplemental NPRM (SNPRM) proposes to make those airplanes with MLG with forging body either at or under 1,750 landings as of March 23, 2007, applicable to the AD in addition to extending the time between the repetitive inspections until a reinforced landing gear is installed, which terminates the repetitive inspections.

Related Service Information Under 1 CFR Part 51

EADS SOCATA has issued TBM Aircraft Mandatory Service Bulletin SB 70-130, ATA No. 32, dated January 2006, and SOCATA has issued DAHER-SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-130, Revision 3, dated December 2014. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. The DAHER-SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-130, Revision 3, dated December 2014, incorporates procedures for replacing cracked MLG with a reinforced MLG as a terminating action for the repetitive inspections. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this NPRM.

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.

Certain changes described above expand the scope of the NPRM. As a result, we have determined that it is necessary to reopen the comment period to provide additional opportunity for the public to comment on the SNPRM.

Costs of Compliance

We estimate that this proposed AD will affect 431 products of U.S. registry. Start Printed Page 33210We also estimate that it would take about 3 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 $109,905, or $255 per product.

In addition, we estimate that any necessary follow-on actions would take about 4 work-hours and require parts costing $6,000, for a cost of $6,340 per product. 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.

Start Amendment Part

2. The FAA amends § 39.13 by removing Amendment 39-14945 ( 72 FR 7576, February 16, 2007), and adding the following new AD:

End Amendment Part

SOCATA (type certificate previously held by EADS SOCATA): Docket No. FAA-2015-2047; Directorate Identifier 2015-CE-013-AD.

(a) Comments Due Date

We must receive comments by July 27, 2015.

(b) Affected ADs

This AD supersedes AD 2007-04-13, Amendment 39-14945, (72 FR 7576, February 16, 2007) (“AD 2007-04-13”).

(c) Applicability

This AD applies to SOCATA Model TBM 700 airplanes, serial numbers 1 through 638 and 687, that:

(1) are not equipped with a left-hand main landing gear (MLG) body part number (P/N) D68161 or D68161-1 and a right-hand MLG body P/N D68162 or D68162-1; and

(2) are certificated in any category.

(d) Subject

Air Transport Association of America (ATA) Code 32: Landing gear.

(e) Reason

This AD was prompted 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 and the FAA's determination to add additional airplanes to the Applicability section. We are issuing this AD to detect and correct cracks in the shock strut cylinder of the MLG, which could cause the MLG to fail, and to add airplanes to the Applicability section. Failure of the shock strut cylinder of the MLG could result in a collapsed MLG during takeoff or landing and possible reduced structural integrity of the airplane. We are superseding AD 2007-04-13 to add airplanes to the Applicability section, increase the time between the repetitive inspections, and incorporate a modification to terminate the required repetitive inspections.

(f) Actions and Compliance for Airplanes not Previously Affected by AD 2007-04-13

Unless already done, do the actions in paragraphs (f)(1), (f)(2), and (h) of this AD:

(1) As of March 23, 2007 (the effective date of AD 2007-04-13), for MLG with forging body that were either at or under 1,750 landings as of March 23, 2007 (the effective date of (AD 2007-04-13): Upon or before accumulating 1,750 landings on the MLG with forging body since new or within the next 100 landings after the effective date of this AD, whichever occurs later, inspect the forging body for cracks. Do the inspection following the Accomplishment Instructions of EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-130, dated January 2006, or DAHER-SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-130, Revision 3, dated December 2014.

(2) If no cracks are detected during the inspection required in paragraph (f)(1) of this AD, repetitively thereafter inspect at intervals not to exceed 240 landings until a reinforced landing gear specified in paragraph E. Terminating Solution of the Accomplishment Instructions in DAHER-SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-130, Revision 3, dated December 2014, is installed.
