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:

On the pre-flight check of a SZD-50-3 glider, the Right Hand (RH) wing airbrake was found impossible to retract. Investigation revealed that the occurrence was caused by a loose bolt of the “V” shape airbrake bellcrank, named hereafter intermediate control lever. The Left Hand (LH) wing lever also presented, to a lesser extent, a loose bolt.

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

DATES:

This AD becomes effective February 1, 2008.

On February 1, 2008, 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 February 21, 2008.

SUPPLEMENTARY INFORMATION:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued Emergency AD No. 2007-0275-E, dated October 24, 2007 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

On the pre-flight check of a SZD-50-3 glider, the Right Hand (RH) wing airbrake was found impossible to retract. Investigation revealed that the occurrence was caused by a loose bolt of the “V” shape airbrake bellcrank, named hereafter intermediate control lever. The Left Hand (LH) wing lever also presented, to a lesser extent, a loose bolt.

This Airworthiness Directive (AD) requires inspection of the LH & RH wing airbrake intermediate control levers for loose attaching bolts and subsequent repetitive inspections and corrective actions, as necessary. As a terminating action, replacement of the bolts and their associated washers is required.

These actions are intended to address the identified unsafe condition so as to prevent loss of the airbrake control system which could result in an inadvertent forced landing with consequent sailplane damage and/or passenger injury.

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

Relevant Service Information

Allstar PZL Glider Sp. z o. o. has issued Service Bulletin No. BE-059/SZD-50-3/2007 “PUCHACZ,” dated October 15, 2007. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. Start Printed Page 3624

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.

This AD is considered an interim action because we are not including a repetitive inspection requirement in this AD. The Administrative Procedure Act does not permit the FAA to “bootstrap” a long-term requirement into an urgent safety of flight action where the rule becomes effective at the same time the public has the opportunity to comment. The short-term action and the long-term action are analyzed separately for justification to bypass prior public notice.

After issuing this AD, we may initiate further AD action (notice of proposed rulemaking followed by a final rule) to require the inspection to be repetitive and to require a terminating action. Credit will be given in any subsequent action for the initial inspection done under this AD.

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 the inability to retract the wing airbrake could cause asymmetrical operation of the airbrake system and result in an unintentional roll. 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-2008-0045; Directorate Identifier 2007-CE-100-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.

2008-02-09 Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa “PZL-Bielsko”: Amendment 39-15339; Docket No. FAA-2008-0045; Directorate Identifier 2007-CE-100-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective February 1, 2008.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Model SZD-50-3 “Puchacz” gliders, all serial numbers up to and including B-2207, 503199327, 503A04001, 503A05002, and 503A05003, certificated in any category.

Subject

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

Reason

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

On the pre-flight check of a SZD-50-3 glider, the Right Hand (RH) wing airbrake was found impossible to retract. Investigation revealed that the occurrence was caused by Start Printed Page 3625a loose bolt of the “V” shape airbrake bellcrank, named hereafter intermediate control lever. The Left Hand (LH) wing lever also presented, to a lesser extent, a loose bolt.

This AD requires inspection of the LH and RH wing airbrake intermediate control levers for loose attaching bolts and subsequent repetitive inspections and corrective actions, as necessary. As a terminating action, replacement of the bolts and their associated washers is required.

These actions are intended to address the identified unsafe condition so as to prevent loss of the airbrake control system which could result in an inadvertent forced landing with consequent sailplane damage and/or passenger injury.

Actions and Compliance

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

(1) Within 10 days after February 1, 2008 (the effective date of this AD), inspect the left-hand (LH) and the right-hand (RH) wing airbrake intermediate control levers for loose attaching bolts following Allstar PZL Glider Sp. z o. o. Service Bulletin No. BE-059/SZD-50-3/2007 “PUCHACZ,” dated October 15, 2007.

(2) Before further flight after the inspection required in paragraph (f)(1) of this AD if any loose bolt is found, on both wings replace the split helical spring lock washers with tab washers and replace the M8x34 bolts with M8x32 bolts following Allstar PZL Glider Sp. z o. o. Service Bulletin No. BE-059/SZD-50-3/2007 “PUCHACZ,” dated October 15, 2007.

(3) No further action is required at this time if no loose bolts were found during the inspection required in paragraph (f)(1) of this AD.

FAA AD Differences

Note:

This AD differs from the MCAI and/or service information as follows:

(1) The MCAI and the service information require repetitive inspections if no loose bolts are found during the initial required inspection until the next 1,000-hour time-in-service (TIS) overhaul after the effective date of the AD, at which time replacing the split helical spring lock washers with tab washers and replacing the M8x34 bolts with M8x32 bolts is required.

(2) This AD is considered an interim action because we are not including a repetitive inspection requirement in this AD. The Administrative Procedure Act does not permit the FAA to “bootstrap” a long-term requirement into an urgent safety of flight action where the rule becomes effective at the same time the public has the opportunity to comment. The short-term action and the long-term action are analyzed separately for justification to bypass prior public notice.

(3) After issuing this AD, we may initiate further AD action (notice of proposed rulemaking followed by a final rule) to require the inspection to be repetitive and to require a terminating action. Credit will be given in any subsequent action for the initial inspection done under this AD.

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. Send information to ATTN: Greg Davison, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4130; fax: (816) 329-409. Before using any approved AMOC on any glider to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.

(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.

(3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
