RIN ID: RIN 2120-AA64

NOTICE: PROPOSED RULES

ACTION: Airworthiness Directives:

DOCUMENT ACTION: Notice of proposed rulemaking (NPRM).

SUBJECT CATEGORY: Airworthiness Directives; Przedsiebiorstwo Doswiadczalno- Produkcyjne Szybownictwa ``PZL-Bielsko'' Model SZD-50-3 ``Puchacz'' Gliders

DATES: We must receive comments on this proposed AD by March 27, 2008.

DOCUMENT SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above that would supersede an existing AD. 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:

On the preflight check of a SZD503 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.

The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

SUMMARY: Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa “PZL-Bielsko” Model SZD-50-3 “Puchacz” Gliders,

Include ``Docket No. FAA20080216; Directorate Identifier 2008CE004AD'' 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:// 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.

Discussion

On January 14, 2008, we issued AD 20080209, Amendment 3915339 (73 FR 3623, January 22, 2008). That AD required actions intended to address an unsafe condition on the products listed above.

AD 20080209 was issued as an interim action in order to address the need for the immediate inspection for loose attachment bolts in the lefthand
[[Page 10189]]
and righthand wing airbrake intermediate control lever requirement and replacement if loose attachment bolts were found.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, issued Emergency AD No. 20070275E, dated October 24, 2007 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products.

The EASA AD allows for repetitive inspections at intervals not to exceed 100 hours timeinservice or 12 months, whichever occurs first after the initial inspection if no loose bolts are found. The EASA AD also requires replacing the split helical spring lock washers with tab washers and the M8x34 bolts with M8x32 bolts on both wings at the next 1,000hour inspection after the effective date of the AD.

The Administrative Procedure Act does not permit the FAA to ``bootstrap'' a longterm 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 shortterm action and the longterm action were analyzed separately for justification to bypass prior public notice.

We are issuing this proposed AD to address the repetitive inspections and mandatory parts replacement issues.

Relevant Service Information

Allstar PZL Glider Sp. z o. o. has issued Service Bulletin No. BE 059/SZD503/2007 ``PUCHACZ,'' dated October 15, 2007. 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.
Differences Between This Proposed 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 also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD.

Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 6 products of U.S. registry. We also estimate that it would take about 1 workhour per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per workhour.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $480, or $80 per product.

In addition, we estimate that any necessary followon actions would take about 12 workhours and require parts costing $40, for a cost of $1,000 per product.

The estimated total cost on U.S. Operators includes the cumulative costs associated with those airplanes affected by AD 20080209. 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); 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 proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

2. The FAA amends Sec. 39.13 by removing Amendment 3915339 (73 FR 3623, January 22, 2008), and adding the following new AD:
Przedsiebiorstwo DoswiadczalnoProdukcyjne Szybownictwa ``PZL Bielsko'': Docket No. FAA20080216; Directorate Identifier 2008CE 004AD.
Comments Due Date
(a) We must receive comments by March 27, 2008.
Affected ADs
(b) This AD supersedes AD 20080209, Amendment 3915339.
Applicability
(c) This AD applies to Model SZD503 ``Puchacz'' gliders, all serial numbers up to and including B2207, 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 preflight check of a SZD503 glider, the Right Hand (RH) wing airbrake was found impossible to retract. Investigation [[Page 10190]]
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 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.
Requirements Retained From AD 20080209
(f) Do the following unless already done:
(1) Within 10 days after February 1, 2008 (the effective date of AD 20080209), inspect the lefthand (LH) and the righthand (RH) wing airbrake intermediate control levers for loose attaching bolts following Allstar PZL Glider Sp. z o. o. Service Bulletin No. BE 059/SZD503/2007 ``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, replace the split helical spring lock washers with tab washers and replace the M8x34 bolts with M8x32 bolts on both wings following Allstar PZL Glider Sp. z o. o. Service Bulletin No. BE059/SZD503/2007
``PUCHACZ,'' dated October 15, 2007. After doing this replacement, no further action is required by this AD.
New Requirements of This AD: Actions and Compliance
(g) If no loose bolts are found in the initial inspection required in paragraph (f)(1) of this AD, repetitively inspect thereafter at intervals not to exceed 100 hours timeinservice (TIS) or 12 months, whichever occurs first, until you are required to do the replacement in paragraph (h) or (i) of this AD. Do the inspection following Allstar PZL Glider Sp. z o. o. Service Bulletin No. BE059/SZD503/2007 ``PUCHACZ,'' dated October 15, 2007.
(h) If any loose bolt is found during any inspection required in paragraph (g) of this AD, before further flight replace the split helical spring lock washers with tab washers and replace the M8x34 bolts with M8x32 bolts on both wings following Allstar PZL Glider Sp. z o. o. Service Bulletin No. BE059/SZD503/2007 ``PUCHACZ,'' dated October 15, 2007. After doing this replacement, no further action is required by this AD.
(i) Within the next 1,000 hours TIS after the effective date of this AD, replace the split helical spring lock washers with tab washers and replace the M8x34 bolts with M8x32 bolts on both wings following Allstar PZL Glider Sp. z o. o. Service Bulletin No. BE 059/SZD503/2007 ``PUCHACZ,'' dated October 15, 2007. After doing this replacement, no further action is required by this AD. FAA AD Differences
