AGENCY:
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
check the maintenance records to
determine whether the brake caliper
piston O-ring seals were replaced at the
last annual or 100-hour inspection. If
the O-rings were not replaced, this
proposed AD would require you to
replace the O-ring seals with new seals
or replace brake calipers. This proposed
AD would also require you to modify
the main landing gear wheel fairings to
add temperature indicator sticker
inspection holes, trim the wheel fairings
to prevent them from holding fluids,
install temperature indicator stickers on
the brake calipers, and insert Revision
A6 (with revised preflight walk-around
and taxi procedures) into the Pilot’s
Operating Handbook (POH). This
proposed AD results from several
reports of airplanes experiencing brake
fires and two airplanes losing
directional control. We are issuing this
proposed AD to detect, correct, and
prevent overheating damage to the brake
caliper piston O-ring seals, which could
result in leakage of brake hydraulic
fluid. Consequently, this could lead to
the loss of braking with loss of airplane
directional control or brake fire.
DATES: We must receive comments on
this proposed AD by July 10, 2006.

26707
right braking during taxi is necessary
due to helical propwash. Excessive
brake use during taxi can result in
overheating damage of the O-ring seals
on the right brake caliper piston.
Consequently, the overheating damage
of the O-ring seals on the brake caliper
piston results in leakage of brake
hydraulic fluid.
In addition to excessive use of the
right brake, data suggests that brake
caliper piston O-ring seals have not
typically been replaced at annual or
100-hour inspections as specified in the
Aircraft Maintenance Manual (AMM).
To address this unsafe condition, CDC
has developed the following:
• Modifications to the main landing
gear (MLG) wheel fairings to add
temperature indicator sticker inspection
holes and trim the wheel fairings to
ensure that any leaking hydraulic fluid
runs onto the pavement where it may be
seen rather than collecting in the wheel
pants;
• Temperature indicator stickers to
install on brake calipers; and
• Revision A6 for the POH (with
revised preflight walk-around and taxi
procedures).
This condition, if not corrected, could
cause leakage of brake hydraulic fluid
and lead to the loss of braking with loss
of airplane directional control or brake
fire.
Relevant Service Information
We have reviewed CDC Service
Bulletins SB 2X–32–13, Issued:
December 15, 2005; and SB 2X–32–14
R1, Issued: January 18, 2006, Revised:
February 17, 2006.
The service information describes
procedures for:
• A wheel conversion and brake
upgrade; and
• Modifications of the MLG fairings
to include inspection holes that
facilitate monitoring (temperature
indicator stickers) for brake assembly
temperature and trimming of the MLG
fairings to provide for additional
clearance;
• Installation of temperature indicator
stickers on the brake assemblies; and
• Incorporation of Revision A6 into
the POH.
Discussion
FAA’s Determination and Requirements
of the Proposed AD
The FAA recently received four
reports of CDC Models SR20 and SR22
airplanes experiencing brake fires and
one airplane losing directional control
resulting in contact with a parked
airplane. There was one prior report of
loss of directional control in 2002.
Investigation has shown that with a
free castering nose wheel, occasional
We are proposing this AD to address
an unsafe condition that we determined
is likely to exist or develop on other
products of this same type design. The
proposed AD would require you to:
• Check the maintenance records to
determine whether the brake caliper
piston O-ring seals were replaced at the
last annual or 100-hour inspection, and,

if not replaced, replace the O-ring seals
with new seals or replace brake calipers;
• Modify the MLG wheel fairings to
add a temperature indicator sticker
inspection hole;
• Trim the wheel fairings to prevent
them from holding fluids;
• Install temperature indicator
stickers on the brake calipers; and
• Insert Revision A6 into the POH.
The proposed AD would require you
to use the service information described
previously to perform these actions.
Differences Between the Proposed AD
and Service Information
The proposed AD would require you
to check the maintenance records to
determine whether the brake caliper
piston O-ring seals were replaced at the
last annual or 100-hour inspection, and,
if not replaced, would require you to
replace the O-ring seals with new seals
or replace brake calipers. This step is
not included in the service bulletin. We
include it in the proposed AD to assure
the O-ring seals are replaced or have
been recently replaced. Replacement
procedures for the brake caliper piston
O-ring seals are in Section 32–42 of the
CDC Model SR20 or SR22 AMM. The
requirements of the proposed AD, if
adopted as a final rule, would take
precedence over the provisions in the
service information.
Costs of Compliance
We estimate that this proposed AD
affects 2,135 airplanes in the U.S.
registry.

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 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.
For the reasons discussed above, I
certify that the 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

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. See the ADDRESSES
section for a location to examine the
regulatory evaluation.

SUMMARY: In an earlier notice of
proposed amendments (NPA), the
FHWA proposed to amend the Manual
on Uniform Traffic Control Devices for
Streets and Highways (MUTCD) to
include methods to maintain traffic sign
retroreflectivity. Based on the review
and analysis of the numerous comments
received in response to the NPA, the
FHWA has decided to substantially
revise the proposed amendments to the
MUTCD and, as a result, is issuing this
SNPA. With this SNPA, the FHWA
proposes to amend the MUTCD to
include a standard for minimum
maintained levels of traffic sign
retroreflectivity and methods to
maintain traffic sign retroreflectivity at
or above these levels.

must be maintained for traffic signs and
pavement markings, which apply to all
roads open to public travel. The FHWA
is currently conducting research to
develop a standard for minimum levels
of pavement marking retroreflectivity.
However, a NPA regarding minimum
pavement marking retroreflectivity is
not expected to be issued until the
rulemaking for minimum traffic sign
retroreflectivity is finalized.
The comment period for the NPA
initially expired on October 28, 2004,
but was extended to February 1, 2005
(69 FR 62007). As of June 1, 2005, the
FHWA received 85 letters submitted to
the docket containing 350 individual
comments on the NPA. The FHWA
received comments from the National
Committee on Uniform Traffic Control
Devices (NCUTCD), the American
Association of State Highway and
Transportation Officials (AASHTO),
State Departments of Transportation
(State DOTs), city and county
governmental agencies, consulting
firms, private industry, associations,
other organizations, and individual
private citizens. The FHWA has
reviewed and analyzed the comments
that were received as of June 1, 2005.
Docket comments and summaries of the
FHWA’s analyses and determinations
are discussed below. After considering
and analyzing the comments, the FHWA
has decided to issue this SNPA. The
proposed changes would be designated
as Revision No. 2 to the 2003 Edition of
the MUTCD.3
The MUTCD is incorporated by
reference in 23 CFR 655.601. It is
available for inspection and copying as
prescribed in 49 CFR part 7 and on the

Airworthiness Directives; Cirrus Design Corporation Model SR20
and SR22 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (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 check the maintenance
records to determine whether the brake caliper piston O-ring seals were
replaced at the last annual or 100-hour inspection. If the O-rings were
not replaced, this proposed AD would require you to replace the O-ring
seals with new seals or replace brake calipers. This proposed AD would
also require you to modify the main landing gear wheel fairings to add
temperature indicator sticker inspection holes, trim the wheel fairings
to prevent them from holding fluids, install temperature indicator
stickers on the brake calipers, and insert Revision A6 (with revised
preflight walk-around and taxi procedures) into the Pilot's Operating
Handbook (POH). This proposed AD results from several reports of
airplanes experiencing brake fires and two airplanes losing directional
control. We are issuing this proposed AD to detect, correct, and
prevent overheating damage to the brake caliper piston O-ring seals,
which could result in leakage of brake hydraulic fluid. Consequently,
this could lead to the loss of braking with loss of airplane
directional control or brake fire.
DATES: We must receive comments on this proposed AD by July 10, 2006.

Discussion
The FAA recently received four reports of CDC Models SR20 and SR22
airplanes experiencing brake fires and one airplane losing directional
control resulting in contact with a parked airplane. There was one
prior report of loss of directional control in 2002.
Investigation has shown that with a free castering nose wheel,
occasional right braking during taxi is necessary due to helical
propwash. Excessive brake use during taxi can result in overheating
damage of the O-ring seals on the right brake caliper piston.
Consequently, the overheating damage of the O-ring seals on the brake
caliper piston results in leakage of brake hydraulic fluid.
In addition to excessive use of the right brake, data suggests that
brake caliper piston O-ring seals have not typically been replaced at
annual or 100-hour inspections as specified in the Aircraft Maintenance
Manual (AMM).
To address this unsafe condition, CDC has developed the following:
Modifications to the main landing gear (MLG) wheel
fairings to add temperature indicator sticker inspection holes and trim
the wheel fairings to ensure that any leaking hydraulic fluid runs onto
the pavement where it may be seen rather than collecting in the wheel
pants;
Temperature indicator stickers to install on brake
calipers; and
Revision A6 for the POH (with revised preflight walk-
around and taxi procedures).
This condition, if not corrected, could cause leakage of brake
hydraulic fluid and lead to the loss of braking with loss of airplane
directional control or brake fire.
Relevant Service Information
We have reviewed CDC Service Bulletins SB 2X-32-13, Issued:
December 15, 2005; and SB 2X-32-14 R1, Issued: January 18, 2006,
Revised: February 17, 2006.
The service information describes procedures for:
A wheel conversion and brake upgrade; and
Modifications of the MLG fairings to include inspection
holes that facilitate monitoring (temperature indicator stickers) for
brake assembly temperature and trimming of the MLG fairings to provide
for additional clearance;
Installation of temperature indicator stickers on the
brake assemblies; and
Incorporation of Revision A6 into the POH.
FAA's Determination and Requirements of the Proposed AD
We are proposing this AD to address an unsafe condition that we
determined is likely to exist or develop on other products of this same
type design. The proposed AD would require you to:
Check the maintenance records to determine whether the
brake caliper piston O-ring seals were replaced at the last annual or
100-hour inspection, and,
[[Page 26708]]
if not replaced, replace the O-ring seals with new seals or replace
brake calipers;
Modify the MLG wheel fairings to add a temperature
indicator sticker inspection hole;
Trim the wheel fairings to prevent them from holding
fluids;
Install temperature indicator stickers on the brake
calipers; and
Insert Revision A6 into the POH.
The proposed AD would require you to use the service information
described previously to perform these actions.
Differences Between the Proposed AD and Service Information
The proposed AD would require you to check the maintenance records
to determine whether the brake caliper piston O-ring seals were
replaced at the last annual or 100-hour inspection, and, if not
replaced, would require you to replace the O-ring seals with new seals
or replace brake calipers. This step is not included in the service
bulletin. We include it in the proposed AD to assure the O-ring seals
are replaced or have been recently replaced. Replacement procedures for
the brake caliper piston O-ring seals are in Section 32-42 of the CDC
Model SR20 or SR22 AMM. The requirements of the proposed AD, if adopted
as a final rule, would take precedence over the provisions in the
service information.
Costs of Compliance
We estimate that this proposed AD affects 2,135 airplanes in the
U.S. registry.
We estimate the following costs to do this proposed check of
maintenance records to determine whether the brake caliper piston O-
ring seals were replaced at the last annual or 100-hour inspection:
----------------------------------------------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
1 workhour x $80 = $80.......... Not applicable..... $80 2,135 x $80 = $170,800.
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to install any necessary O-ring
seals that would be required based on the results of this proposed
check of maintenance records. We have no way of determining the number
of airplanes that may need this seal installation:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
4 work hours x $80 = $320............... $8 $328
------------------------------------------------------------------------
We estimate the following costs to replace any brake calipers on
Model SR20 airplanes, serial numbers (S/Ns) 1005 through 1194, that
would be required based on the results of this proposed check of
maintenance records. We have no way of determining the number of these
Model SR20 airplanes that may need to replace brake calipers:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
12 workhours x $80 = $960............... $1,167 $2,127
------------------------------------------------------------------------
We estimate the following costs to replace any brake calipers on
Model SR20 airplanes, S/Ns 1195 through 1600, that would be required
based on the results of this proposed check of maintenance records. We
have no way of determining the number of these Model SR20 airplanes
that may need to replace brake calipers:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
8 workhours x $80 = $640................ $1,167 $1,807
------------------------------------------------------------------------
We estimate the following costs to replace any brake calipers on
Model SR22 airplanes that would be required based on the results of
this proposed check of maintenance records. We have no way of
determining the number of Model SR22 airplanes that may need to replace
brake calipers:
------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
5 workhours x $80 = $400................ $845 $1,245
------------------------------------------------------------------------
We estimate the following costs to do the proposed modification of
the MLG wheel fairings to add the temperature indicator sticker
inspection holes, trim the wheel fairings to prevent them from holding
fluids, and install the temperature indicator sticker on the brake
calipers:
[[Page 26709]]

----------------------------------------------------------------------------------------------------------------
2 workhours x $80 = $160.......... $2 $162 2,135 x $162 = $345,870.
----------------------------------------------------------------------------------------------------------------
The CDC has indicated that CDC will provide warranty credit as
stated in the service information for modifying the MLG wheel fairings
by adding the temperature indicator sticker inspection holes, trimming
the wheel fairings to prevent them from holding fluids, and installing
the temperature indicator sticker on the brake calipers.
We estimate the following costs to do the proposed insertion of
Revision A6 into the POH:

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 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.
For the reasons discussed above, I certify that the 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. See the ADDRESSES section for a location
to examine the regulatory evaluation.
Examining the Dockets
You may examine the docket that contains the proposal, any comments
received and any final disposition on the Internet at https://
dms.dot.gov, or in person at the DOT Docket Offices between 9 a.m. and
5 p.m., Monday through Friday, except Federal holidays. The Docket
Office (telephone 1-800-647-5227) is located on the plaza level of the
Department of Transportation Nassif Building at the street address
stated in ADDRESSES. Comments will be available in the AD docket
shortly after the Docket Management Facility receives them.
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 Federal Aviation Administration proposes to amend 14
CFR part 39 as follows:
