Airworthiness Directives; Przedsiebiorstwo Doswiadczalno-
Produkcyjne Szybownictwa ``PZL-Bielsko'' Model SZD-50-3 ``Puchacz''
Gliders
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
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 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.
The proposed AD would require actions that are intended to address
the unsafe condition described in the MCAI.
DATES: We must receive comments on this proposed AD by March 27, 2008.

Discussion
On January 14, 2008, we issued AD 2008-02-09, Amendment 39-15339
(73 FR 3623, January 22, 2008). That AD required actions intended to
address an unsafe condition on the products listed above.
AD 2008-02-09 was issued as an interim action in order to address
the need for the immediate inspection for loose attachment bolts in the
left-hand
[[Page 10189]]
and right-hand 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. 2007-0275-E, 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 time-in-service 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
1,000-hour inspection after the effective date of the 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 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/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.
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 work-hour per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour.
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 follow-on actions would
take about 12 work-hours 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 2008-02-09.
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 39--AIRWORTHINESS 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 39-15339 (73 FR
3623, January 22, 2008), and adding the following new AD:
Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa ``PZL-
Bielsko'': Docket No. FAA-2008-0216; Directorate Identifier 2008-CE-
004-AD.
Comments Due Date
(a) We must receive comments by March 27, 2008.
Affected ADs
(b) This AD supersedes AD 2008-02-09, Amendment 39-15339.
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
[[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 2008-02-09
(f) Do the following unless already done:
(1) Within 10 days after February 1, 2008 (the effective date of
AD 2008-02-09), 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, 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/SZD-50-3/2007
``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 time-in-service
(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. BE-059/SZD-50-3/2007 ``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. BE-059/SZD-50-3/2007 ``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/SZD-50-3/2007 ``PUCHACZ,'' dated October 15, 2007. After doing
this replacement, no further action is required by this AD.
