Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Cracks on the lug of the rear attachment fitting of the horizontal stabilizer have been detected during the inspection of two PW-6U gliders operated by the same user.

This condition, if not corrected, could result in no longer retaining the horizontal stabilizer in place and consequent loss of control of the aeroplane.

This AD requires actions that are intended to address the unsafe condition described in the MCAI.

DATES:

This AD becomes effective August 16, 2010.

On August 16, 2010, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

We must receive comments on this AD by September 10, 2010.

SUPPLEMENTARY INFORMATION:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. ­2010-0108-E, dated June 8, 2010 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

Cracks on the lug of the rear attachment fitting of the horizontal stabilizer have been detected during the inspection of two PW-6U gliders operated by the same user.

This condition, if not corrected, could result in no longer retaining the horizontal stabilizer in place and consequent loss of control of the aeroplane.

For the reasons described above, this AD requires immediate and periodic inspections of the horizontal stabilizer rear attachment fitting and the accomplishment of the relevant corrective actions as necessary.

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

Relevant Service Information

Zakład Szybowcowy “Jeżów” Henryk Mynarski has issued Mandatory Bulletin BO-78-10-10, dated June 7, 2010. 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 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 issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

Differences Between This AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

We might have also required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are described in a separate paragraph of the AD. These requirements take precedence over those copied from the MCAI.

FAA's 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 cracks on the lug of the rear attachment fitting of the horizontal stabilizer have been found. This condition, if not detected and corrected, Start Printed Page 43808could cause the horizontal stabilizer to fail, which could result in loss of control. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2010-0729; Directorate Identifier 2010-CE-032-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.

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.

For the reasons discussed above, I certify that this AD:

(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); and

(3) 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.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

Effective Date

(a) This airworthiness directive (AD) becomes effective August 16, 2010.

Affected ADs

(b) None.

Applicability

(c) This AD applies to the following Zakład Szybowcowy “Jeżów” Henryk Mynarski Model PW-6U sailplanes, certificated in any category:

(i) Serial numbers (S/Ns) 78.00.00 through 78.03.07 equipped with an automatic elevator control connection installed in accordance with Zakład Szybowcowy “Jeżów” Henryk Mynarski Bulletin BS-78-02-04;

(ii) S/Ns 78.03.08 through 78.03.10; and

(iii) S/Ns 78.04.01 and subsequent S/Ns.

Subject

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

Reason

(e) The mandatory continuing airworthiness information (MCAI) states:

Cracks on the lug of the rear attachment fitting of the horizontal stabilizer have been detected during the inspection of two PW-6U gliders operated by the same user.

This condition, if not corrected, could result in no longer retaining the horizontal stabilizer in place and consequent loss of control of the aeroplane.

For the reasons described above, this AD requires immediate and periodic inspections of the horizontal stabilizer rear attachment fitting and the accomplishment of the relevant corrective actions as necessary.

Actions and Compliance

(f) Unless already done, do the following actions.

(1) Before further flight after the effective date of this AD, repetitively thereafter at intervals not to exceed 50 hours time-in-service, and, in addition, before further flight anytime the sailplane experiences a “hard landing,” visually inspect the rear attachment fitting of the horizontal stabilizer for cracks and damage. Do the inspections following Zakład Szybowcowy “Jeżów” Henryk Mynarski Mandatory Bulletin BO-78-10-10, dated June 7, 2010, except use a 10X magnifier.

(2) If any crack or damage is found during any inspection required in paragraph (f)(1) of this AD, before further flight after the inspection in which a crack or damage is found, contact Zakład Szybowcowy “Jeżów” Henryk Mynarski, ul. Długa 93, 58-521 Jeżów Sudecki, Poland, telephone/fax: +48 75 713 21 59 or +48 33 829 33 72; e-mail: szdjezow.com.pl, to obtain an FAA-approved repair scheme and incorporate the repair scheme.

FAA AD Differences

Note:

This AD differs from the MCAI and/or service information as follows. The service information requires a visual inspection with a 5X magnifier. For the inspection, we are requiring a 10X magnifier to detect cracks and damage that may go undetected using only a 5X magnifier.

Other FAA AD Provisions

(g) 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.
