Start Preamble

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are superseding an existing airworthiness directive (AD) for all Alexander Schleicher GmbH & Co. Segelflugzeugbau Models AS -K13, Ka2B, Ka 6, Ka 6 B, Ka 6 BR, Ka 6 C, Ka 6 CR, K7, K8, and K 8 B sailplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority Start Printed Page 53631of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as misalignment of the automatic elevator control connection. We are issuing this AD to require actions to address the unsafe condition on these products.

DATES:

This AD is effective October 4, 2013.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of October 4, 2013.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. The NPRM was published in the Federal Register on May 23, 2013 (78 FR 30791), and proposed to supersede AD 64-07-05, Amendment 701 (29 FR 3227, March 11, 1964) (“AD 64-07-05”). The NPRM proposed to correct an unsafe condition for the specified products.

Since we issued AD 64-07-05, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, issued a new AD, AD No. 2013-0091, dated April 12, 2013 (referred to after this as “the MCAI”), to add additional sailplane models to the applicability and to add additional inspections of the elevator control connection. Alexander Schleicher GmbH & Co. Segelflugzeugbau has also issued revised service information to address the unsafe condition. The MCAI states:

A recent report has been received concerning a problem with the elevator control during take-off of an ASK 13 sailplane. The results of the technical investigation revealed a misalignment in the automatic elevator control connection, presumably caused by an incorrect repair or damage at the tail-plane-area. In addition, similar elevator connection failure during early 1960's which led to the issuance of LBA LTM 4/62. However, LTM, 4/62 did not apply to ASK 13 and ASK 18 sailplanes coming later into production.

This condition, if not detected and corrected, could lead to failure of the automatic elevator control connection, possibly resulting in loss of control of the sailplane.

To address this unsafe condition, Alexander Schleicher GmbH issued a Technical Note (TN) (Ka 6 TN-Nr. 26; K 7 TN-Nr. 24; K 8 TN-Nr. 30; ASK 13 TN-Nr. 19; ASK 18 TN-Nr. 9) providing instructions for elevator control inspection and replacement and EASA issued AD 2012-0246 to require accomplishment of those instructions.

Since that AD was issued, Alexander Schleicher GmbH issued a revision of TN (Ka 6 TN-Nr. 26; K 7 TN-Nr. 24; K 8 TN-Nr. 30; ASK 13 TN-Nr. 19, ASK 18 TN-Nr. 9), dated 08 January 2013 to re-introduce a pushrod support modification for K 7 and K 8 sailplanes, previously required by LBA LTM 4/62, but no longer required by EASA AD 2012-0246, which superseded the LBA LTM.

For the reasons described above, this AD retains the requirements of EASA AD 2012-0246, which is superseded, and additionally requires, for K 7 and K 8 sailplanes, verification of embodiment of pushrod support modification, and depending on finding, pushrod support modification.

You may obtain further information by examining the MCAI in the AD docket.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 30791, May 23, 2013) or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes:

  • Are consistent with the intent that was proposed in the NPRM (78 FR 30791, May 23, 2013) for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 30791, May 23, 2013).

Costs of Compliance

We estimate that this AD will affect 127 products of U.S. registry. We also estimate that it will take about .5 work-hour per product to comply with the new inspection requirements of this AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the initial inspection required in this AD on U.S. operators to be $5,397.50, or $42.50 per product.

We have no way of determining the number of repetitive inspections an owner/operator will incur over the life of the sailplane.

In addition, we estimate that any necessary follow-on actions will take about 1 work-hour and require parts costing $119, for a cost of $204 per product. We have no way of determining the number of products that may need these actions.

We also estimate that it will take about 2 work-hours per product to comply with actions retained from AD 64-07-05 for Models Ka2B, Ka 6, Ka 6 B, Ka 6 BR, Ka 6 C, Ka 6 CR, K7, K8, and K 8 B sailplanes in this AD, which affects 112 products of U.S. registry, and may require parts costing $103, for a cost of $273 per product.

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 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.Start Printed Page 53632

For the reasons discussed above, I certify 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),

(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.

Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.gov;​ or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 647-5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

(a) Effective Date

This airworthiness directive (AD) becomes effective October 4, 2013.

(b) Affected ADs

This AD supersedes AD 64-07-05, Amendment 701 (29 FR 3227; March 11, 1964).

(c) Applicability

This AD applies to Alexander Schleicher GmbH & Co. Segelflugzeugbau Models AS -K13, Ka2B, Ka 6, Ka 6 B, Ka 6 BR, Ka 6 C, Ka 6 CR, K7, K8, and K 8 B sailplanes, all serial numbers, certificated in any category.

(d) Subject

Air Transport Association of America (ATA) Code 27: Flight Controls.

(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 misalignment of the automatic elevator control connection. The European Aviation Safety Agency (EASA) has issued a new AD to add additional sailplane models to the applicability and to add additional inspections of the elevator control connection. Alexander Schleicher GmbH & Co. Segelflugzeugbau has also issued revised service information to address the unsafe condition. We are issuing this AD to prevent failure of the automatic elevator control connection, which could result in loss of control.
