DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2006-24254; Directorate Identifier 2006-CE-24-AD;
Amendment 39-14767; AD 2006-19-10]
RIN 2120-AA64
Airworthiness Directives; Cirrus Design Corporation Models SR20
and SR22 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) that
supersedes AD 2005-17-19, which applies to certain Cirrus Design
Corporation (CDC) Models SR20 and SR22 airplanes. AD 2005-17-19
currently requires you to measure and adjust the crew seat break-over
bolts and to replace the crew seat recline locks on both crew seats.
Since we issued AD 2005-17-19, CDC developed new crew seat break-over
pins to replace the old crew seat break-over bolts. Consequently, this
AD retains the action from AD 2005-17-19 of replacing the crew seat
recline locks on both seats and adds the action of replacing the crew
seat break-over bolts with the new crew seat break-over pins on both
seats. We are issuing this AD to prevent the crew seats from folding
forward during emergency landing dynamic loads with consequent occupant
injury.
DATES: This AD becomes effective on October 24, 2006.
As of October 24, 2006 the Director of the Federal Register
approved the incorporation by reference of Cirrus Design Corporation
Service Bulletin SB 2X-25-17 R1, Issued: December 15, 2005, Revised:
January 20, 2006.
As of October 13, 2005 (70 FR 51999, September 1, 2005), the
Director of the Federal Register previously approved the incorporation
by reference of Cirrus Design Corporation Service Bulletin SB 2X-25-06
R4, Issued: August 13, 2004; Revised: May 5, 2005.

SUPPLEMENTARY INFORMATION:
Discussion
On April 25, 2006, we issued a proposal to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to certain CDC Models SR20 and SR22 airplanes. This
proposal was published in the Federal Register as a notice of proposed
rulemaking (NPRM) on May 2, 2006 (71 FR 25785). The NPRM proposed to
supersede AD 2005-17-19, Amendment 39-14240 (70 FR 51999, September 1,
2005), retain the action of replacing the crew seat recline locks on
both seats, and add the action of replacing the crew seat break-over
bolts with the new crew seat break-over pins on both seats.
Comments
We provided the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
and FAA's response to each comment:
Comment Issue
We received one comment from Jenna Deutschmann. The commenter
supports the AD but believes the manufacturer should be liable to
correct and pay for the problem since it involves a malfunction on
their part.
The FAA issues ADs to correct unsafe conditions. We do not identify
who will pay for the parts or labor. In this case, CDC will provide
warranty credit to the extent noted in Service Bulletins SB 2X-25-17
R1, Issued: December 15, 2005, Revised: January 20, 2006; and SB 2X-25-
06 R4, Issued: August 13, 2004, Revised: May 5, 2005.
We are not changing the AD as a result of this comment.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
except for minor editorial corrections. We have determined that these
minor corrections:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 2,230 airplanes in the U.S.
registry.
We estimate the following costs to do the required replacements:
[[Page 54756]]
----------------------------------------------------------------------------------------------------------------
Model number and serial Total cost per Total cost on
Labor cost number Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
Replacement of the recline locks: 1 Model SR20, serial $83 $163 $41,565

Replacement of the recline locks: 1 Model SR22, S/N 0002 89 169 176,267

Replacement of the crew seat break- Model SR20, S/N 1005 33 113 262,273

----------------------------------------------------------------------------------------------------------------
Note: CDC will provide warranty credit to the extent noted in
Service Bulletins SB 2X-25-17 R1, Issued: December 15, 2005,
Revised: January 20, 2006; and SB 2X-25-06 R4, Issued: August 13,
2004, Revised: May 5, 2005.
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 AD.
Regulatory Findings
We have 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 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 summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``Docket
No. FAA-2006-24254; Directorate Identifier 2006-CE-24-AD'' in your
request.
