14 CFR Part 39
[Docket No. FAA-2004-19694; Directorate Identifier 2004-CE-41-AD]
RIN 2120-AA64
Airworthiness Directives; Cirrus Design Corporation Model SR20
and SR22 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Cirrus Design Corporation (CDC) Model SR20 and SR22
airplanes. This proposed AD would require you to measure and adjust the
crew seat break-over bolts and to replace the crew seat recline locks
on both crew seats. This proposed AD results from CDC discovering that
the crew seats, under emergency landing dynamic loads, may fold forward
at less than 26 G required by the regulations. We are issuing this
proposed AD to prevent the crew seats from folding forward during
emergency landing with dynamic loads with consequent occupant injury.
DATES: We must receive any comments on this proposed AD by February 24,
2005.
ADDRESSES: Use one of the following to submit comments on this proposed
AD:
DOT Docket Web site: Go to http://dms.dot.gov and follow
the instructions for sending your comments electronically.
Government-wide rulemaking Web site: Go to http://www.regulations.gov
and follow the instructions for sending your
comments electronically.
Mail: Docket Management Facility; U.S. Department of
Transportation, 400 Seventh Street, SW., Nassif Building, Room PL-401,

Discussion
What events have caused this proposed AD? The Cirrus Design
Corporation (CDC) performed dynamic seat testing on Models SR20 and
SR22 airplanes. CDC found that, under emergency landing dynamic loads,
the crew seats may fold forward at less than the 26 Gs required by 14
CFR Section 23.562 (b) (2).
What is the potential impact if FAA took no action? If not
prevented, the crew seats folding forward during emergency landing with
dynamic loads could result in occupant injury.
Is there service information that applies to this subject? Cirrus
Design Corporation has issued Service Bulletin SB 2X-25-06 R2, dated
December 6, 2004, and Service Bulletin SB A2X-25-08, dated June 22,
2004.
What are the provisions of this service information? The service
bulletins include procedures for:
--Inspecting crew seat break-over bolts;
--Adjusting the crew seat break-over bolts;
--Checking recline lock identification;
--Performing recline lock replacement; and
--Checking break-over pin alignment.
FAA's Determination and Requirements of This Proposed AD
What has FAA decided? We have evaluated all pertinent information
and
[[Page 2371]]
identified an unsafe condition that is likely to exist or develop on
other products of this same type design. For this reason, we are
proposing AD action.
What would this proposed AD require? This proposed AD would require
you to incorporate the actions in the previously-referenced service
bulletins.
How does the revision to 14 CFR part 39 affect this proposed AD? On
July 10, 2002, we published a new version of 14 CFR part 39 (67 FR
47997, July 22, 2002), which governs FAA's AD system. This regulation
now includes material that relates to altered products, special flight
permits, and alternative methods of compliance. This material
previously was included in each individual AD. Since this material is
included in 14 CFR part 39, we will not include it in future AD
actions.
Costs of Compliance
How many airplanes would this proposed AD impact? We estimate that
this proposed AD affects 1,501 airplanes in the U.S. registry.
What would be the cost impact of this proposed AD on owners/
operators of the affected airplanes? CDC will provide warranty credit
for service bulletins SB A2X-25-08, dated June 22, 2004, and SB 2X-25-
06 R2, dated December 6, 2004.
Authority for This Rulemaking
What authority does FAA have for issuing this rulemaking action?
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
Would this proposed AD impact various entities? We have 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.
Would this proposed AD involve a significant rule or regulatory
action? For the reasons discussed above, I certify that this proposed
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 proposed AD
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
``AD Docket FAA-2004-19694; Directorate Identifier 2004-CE-41-AD'' in
your request.
