The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2005–23145; Directorate Identifier 2000–NM–215–AD] RIN 2120–AA64 Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB–145, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all EMBRAER Model EMB–145, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP airplanes. The existing AD currently requires repetitive inspections to detect cracking or failure of the rod ends of the aileron power control actuator (PCA), and corrective actions if necessary. This proposed AD would require the same repetitive inspections of additional parts at new inspection intervals for certain airplanes; provide new corrective actions; and provide an optional terminating action for the proposed requirements. This proposed AD results from the issuance of mandatory continuing airworthiness information by the Brazilian airworthiness authority. We are proposing this AD to detect and correct cracking or breaking of the rod ends and connecting fittings of the aileron PCA, which could result in reduced controllability of the airplane. DATES: We must receive comments on this proposed AD by January 6, 2006. ADDRESSES: Use one of the following addresses to submit comments on this proposed AD. • DOT Docket Web site: Go to https://dms.dot.gov and follow the VerDate Aug<31>2005 13:00 Dec 06, 2005 Jkt 208001 instructions for sending your comments electronically. • Government-wide rulemaking Web site: Go to https://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, Washington, DC 20590. • Fax: (202) 493–2251. • Hand Delivery: Room PL–401 on the plaza level of the Nassif Building, 400 Seventh Street, SW., Washington, DC, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Discussion On March 16, 1999, we issued AD 99– 05–04, amendment 39–11087 (64 FR 13892, March 23, 1999), for all EMBRAER Model EMB–145, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP airplanes. That AD requires repetitive inspections to detect cracking or failure of the rod ends of the aileron power control actuator (PCA), and corrective actions if necessary. That AD resulted from the issuance of mandatory continuing airworthiness information by the Brazilian civil aviation authority, the Departmento de Aviacao Civil (DAC). We issued that AD to detect and correct cracking or failure of the rod ends of the aileron PCA, which could result in reduced controllability of the airplane. Actions Since Existing AD Was Issued Since we issued AD 99–05–04, the DAC notified us that it has received additional reports of broken rod ends of the aileron PCA, involving part numbers (P/N) on which AD 99–05–04 did not apply. The rod ends were broken either at the aileron or at the wing side of the PCA. More recently, there have been reports of cracking in the aileron PCA fittings at the wing side. Failure/ breaking of the aileron PCA rod ends or connecting fittings, if not corrected, could result in reduced controllability of the airplane. Relevant Service Information EMBRAER has issued the following service documents: 1. Service Bulletin 145–27–0054, Change 03, dated March 30, 2000; and Service Bulletin 145–27–0054, Change E:\FR\FM\07DEP1.SGM 07DEP1 Federal Register / Vol. 70, No. 234 / Wednesday, December 7, 2005 / Proposed Rules 04, dated February 14, 2005. For PCAs having certain P/Ns, these service bulletins describe procedures for repetitive visual inspections for cracking or failure of the aileron PCA rod ends and connecting fittings at the aileron connection points for the wing structure. Among other things, these service bulletins also describe procedures for corrective actions that include replacing PCAs that have cracked or failed rod ends with new PCAs, replacing cracked or failed fittings with new reinforced fittings, and replacing any aileron having any discrepancy found during the described inspections with a new or serviceable aileron. 2. Service Bulletin 145–57–0019, Change 02, dated May 3, 2001; and Service Bulletin 145–57–0019, Change 03, dated February 11, 2004. These service bulletins describe procedures for replacing all PCA connecting fittings with new, redesigned, and reinforced fittings in the half-wings, among other actions. EMBRAER recommends that these service bulletins be done at the same time as the actions in EMBRAER Service Bulletin 145–27–0061 and in EMBRAER Service Bulletin 145–27– 0062 (both described below). 3. Service Bulletin 145–27–0061, Change 02, dated September 12, 2000; Service Bulletin 145–27–0061, Change 03, dated March 14, 2001; and Service Bulletin 145–27–0061, Revision 04, dated August 11, 2004. These service bulletins describe procedures for reinforcing the aileron PCA fittings and reidentifying the aileron. EMBRAER recommends that these service bulletins be done at the same time as the actions in EMBRAER Service Bulletins 145–57– 0019 and 145–27–0062. 4. Service Bulletin 145–27–0062, Revision 03, dated December 11, 2002; and Service Bulletin 145–27–0062, Revision 04, dated March 8, 2004. For PCAs with certain P/Ns, these service bulletins describe procedures for replacing the aileron PCAs with new, improved aileron PCAs, among other actions. EMBRAER recommends that the actions in EMBRAER Service Bulletins 145–57–0019 and 145–27– 0061 be done before the actions in these service bulletins. These service bulletins also specify that operators send the replaced PCAs to the parts manufacturer. 5. Service Bulletin 145–27–0063, dated March 30, 2000; Service Bulletin 145–27–0063, Change 01, dated October 2, 2000; Service Bulletin 145–27–0063, Change 02, dated March 22, 2002; Service Bulletin 145–27–0063, Change 03, dated May 27, 2004; Service Bulletin 145–27–0063, Revision 04, dated October 13, 2004; and Service Bulletin 145–27–0063, Revision 05, dated March 16, 2005. These service bulletins describe procedures for installing an aileron damper and modifying the hydraulic system, among other actions. 6. Subtask 27–12–01–212–002–A00 of the EMBRAER EMB–145 Aircraft Maintenance Manual. This subtask provides procedures for inspecting the aileron PCA rod ends and fitting lugs. The DAC mandated the service information and issued Brazilian airworthiness directive 1999–02–01R6, dated June 21, 2004, to ensure the continued airworthiness of these airplanes in Brazil. FAA’s Determination and Requirements of the Proposed AD These airplane models are manufactured in Brazil and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DAC has kept the FAA informed of the situation described above. We have examined the DAC’s findings, evaluated all pertinent information, and determined that AD action is necessary for airplanes of this type design that are certificated for operation in the United States. This proposed AD would supersede AD 99–05–04 and would continue to require repetitive inspections to detect cracking or failure of the rod ends of the aileron PCA, and corrective actions if necessary. This proposed AD would also: 1. Require the same repetitive inspections of additional P/Ns at new inspection intervals for certain airplanes; 2. Provide new corrective actions; 3. Require use of a new revision of the previously required service bulletin; and 4. Provide an optional terminating action for the proposed requirements. The proposed AD would require you to use the service information described previously to perform these actions. Differences Between the Proposed AD and the Brazilian Airworthiness Directive The Brazilian airworthiness directive does not give a compliance time for the initial inspection of the PCA rod ends and fittings. We would require that inspection to be done at the applicable time specified in the following table, ‘‘Compliance Times for Initial Inspection.’’ In developing an appropriate compliance time for this inspection, we considered the manufacturer’s recommendation, the degree of urgency associated with the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the inspection (1 hour). We also considered that the referenced service bulletin (EMBRAER Service Bulletin 145–27– 0054, Change 03, dated March 30, 2000), which contains the procedures for accomplishing the required inspection, has been available to all operators of the subject EMBRAER airplanes since March 2000. (EMBRAER Service Bulletin 145–27–0054, Change 03, was revised on February 14, 2005, to add two airplanes to the effectivity; we understand that the actions specified in the service bulletin have been accomplished on those two airplanes.) In light of all of these factors, we find that the initial inspection must be accomplished at the applicable time specified in the table below, which represents an appropriate interval of time allowable for affected airplanes to continue to operate without compromising safety. TABLE.—COMPLIANCE TIMES FOR INITIAL INSPECTION For airplanes that have PCAs with these part numbers (P/N)— 394900–1003 or 394900–1005 ................................................................ 394900–1007 ............................................................................................ 418800–1001, 418800–1003, 418800–9003, 418800–1005, 418800– 9005, 418800–1007, or 418800–9007; and that have new reinforced PCA fittings installed in accordance with paragraph (k) or (l) of this AD.

Sfmt 4702 72727 E:\FR\FM\07DEP1.SGM 07DEP1 72728 Federal Register / Vol. 70, No. 234 / Wednesday, December 7, 2005 / Proposed Rules The Brazilian airworthiness directive also does not give a compliance time for replacing cracked or failed PCA fittings or rod ends. This proposed AD would require replacing any cracked or failed part before further flight. In addition, the Brazilian airworthiness directive does not specify what operators should do when no cracked or failed aileron PCA rod ends or connecting fittings are found. This AD would require the inspection to be repeated at the intervals specified in the following table. TABLE.—REPEAT INSPECTION INTERVALS For airplanes that have PCAs with these part numbers (P/N)— Repeat the inspection— 394900–1003 or 394900–1005 ................................................................ At intervals not to exceed 25 flight hours or 3 days, whichever occurs later. At intervals not to exceed 100 flight hours or 14 days, whichever occurs later. At intervals not to exced 500 flight hours. 394900–1007 ............................................................................................ 418800–1001, 418800–1003, 418800–9003, 418800–1005, 418800– 9005, 418800–1007, or 418800–9007; and that have new reinforced PCA fittings installed in accordance with paragraph (j) or (k) of this AD. These differences have been coordinated with the DAC and they are in agreement. Change to Existing AD This proposed AD would retain certain requirements of AD 99–05–04. Since AD 99–05–04 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this proposed AD, as listed in the following table: REVISED PARAGRAPH IDENTIFIERS Requirement in AD 99–05–04 Paragraph (a) ............ Paragraph (b) ............ Corresponding requirement in this proposed AD Paragraph (f). Paragraph (g). In addition, all references to a ‘‘detailed visual inspection’’ have been changed to refer to a ‘‘detailed inspection.’’ A definition of detailed inspection is included in Note 1 of the proposed AD. We have also removed the requirement in paragraph (c) of AD 99– 05–04 to send a report of any cracked or failed rod end to the Manager, Atlanta Aircraft Certification Office, FAA. We no longer need this information from operators. Interim Action We consider this proposed AD interim action. If final action is later identified, we may consider further rulemaking then. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this proposed AD. ESTIMATED COSTS Action Average labor rate per hour Work hours Inspections (required by AD 99–05–04). Inspections (new proposed action for airplanes subject to EMBRAER Service Bulletin 145–27–0054).

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 13:00 Dec 06, 2005 Number of U.S.registered airplanes Cost per airplane 1 Authority for This Rulemaking VerDate Aug<31>2005 Parts Jkt 208001 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 PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 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 E:\FR\FM\07DEP1.SGM 07DEP1 Federal Register / Vol. 70, No. 234 / Wednesday, December 7, 2005 / Proposed Rules under the criteria of the Regulatory Flexibility Act.

Airworthiness Directives; Empresa Brasileira de Aeronautica S.A.
(EMBRAER) Model EMB-145, -145ER, -145MR, -145LR, -145XR, -145MP, and -
145EP Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede an existing airworthiness
directive (AD) that applies to all EMBRAER Model EMB-145, -145ER, -
145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The existing AD
currently requires repetitive inspections to detect cracking or failure
of the rod ends of the aileron power control actuator (PCA), and
corrective actions if necessary. This proposed AD would require the
same repetitive inspections of additional parts at new inspection
intervals for certain airplanes; provide new corrective actions; and
provide an optional terminating action for the proposed requirements.
This proposed AD results from the issuance of mandatory continuing
airworthiness information by the Brazilian airworthiness authority. We
are proposing this AD to detect and correct cracking or breaking of the
rod ends and connecting fittings of the aileron PCA, which could result
in reduced controllability of the airplane.

DATES: We must receive comments on this proposed AD by January 6, 2006.

Discussion

On March 16, 1999, we issued AD 99-05-04, amendment 39-11087 (64 FR
13892, March 23, 1999), for all EMBRAER Model EMB-145, -145ER, -145MR,
-145LR, -145XR, -145MP, and -145EP airplanes. That AD requires
repetitive inspections to detect cracking or failure of the rod ends of
the aileron power control actuator (PCA), and corrective actions if
necessary. That AD resulted from the issuance of mandatory continuing
airworthiness information by the Brazilian civil aviation authority,
the Departmento de Aviacao Civil (DAC). We issued that AD to detect and
correct cracking or failure of the rod ends of the aileron PCA, which
could result in reduced controllability of the airplane.

Actions Since Existing AD Was Issued

Since we issued AD 99-05-04, the DAC notified us that it has
received additional reports of broken rod ends of the aileron PCA,
involving part numbers (P/N) on which AD 99-05-04 did not apply. The
rod ends were broken either at the aileron or at the wing side of the
PCA. More recently, there have been reports of cracking in the aileron
PCA fittings at the wing side. Failure/breaking of the aileron PCA rod
ends or connecting fittings, if not corrected, could result in reduced
controllability of the airplane.

Relevant Service Information

EMBRAER has issued the following service documents:
1. Service Bulletin 145-27-0054, Change 03, dated March 30, 2000;
and Service Bulletin 145-27-0054, Change

[[Page 72727]]

04, dated February 14, 2005. For PCAs having certain P/Ns, these
service bulletins describe procedures for repetitive visual inspections
for cracking or failure of the aileron PCA rod ends and connecting
fittings at the aileron connection points for the wing structure. Among
other things, these service bulletins also describe procedures for
corrective actions that include replacing PCAs that have cracked or
failed rod ends with new PCAs, replacing cracked or failed fittings
with new reinforced fittings, and replacing any aileron having any
discrepancy found during the described inspections with a new or
serviceable aileron.
2. Service Bulletin 145-57-0019, Change 02, dated May 3, 2001; and
Service Bulletin 145-57-0019, Change 03, dated February 11, 2004. These
service bulletins describe procedures for replacing all PCA connecting
fittings with new, redesigned, and reinforced fittings in the half-
wings, among other actions. EMBRAER recommends that these service
bulletins be done at the same time as the actions in EMBRAER Service
Bulletin 145-27-0061 and in EMBRAER Service Bulletin 145-27-0062 (both
described below).
3. Service Bulletin 145-27-0061, Change 02, dated September 12,
2000; Service Bulletin 145-27-0061, Change 03, dated March 14, 2001;
and Service Bulletin 145-27-0061, Revision 04, dated August 11, 2004.
These service bulletins describe procedures for reinforcing the aileron
PCA fittings and reidentifying the aileron. EMBRAER recommends that
these service bulletins be done at the same time as the actions in
EMBRAER Service Bulletins 145-57-0019 and 145-27-0062.
4. Service Bulletin 145-27-0062, Revision 03, dated December 11,
2002; and Service Bulletin 145-27-0062, Revision 04, dated March 8,
2004. For PCAs with certain P/Ns, these service bulletins describe
procedures for replacing the aileron PCAs with new, improved aileron
PCAs, among other actions. EMBRAER recommends that the actions in
EMBRAER Service Bulletins 145-57-0019 and 145-27-0061 be done before
the actions in these service bulletins. These service bulletins also
specify that operators send the replaced PCAs to the parts
manufacturer.
5. Service Bulletin 145-27-0063, dated March 30, 2000; Service
Bulletin 145-27-0063, Change 01, dated October 2, 2000; Service
Bulletin 145-27-0063, Change 02, dated March 22, 2002; Service Bulletin
145-27-0063, Change 03, dated May 27, 2004; Service Bulletin 145-27-
0063, Revision 04, dated October 13, 2004; and Service Bulletin 145-27-
0063, Revision 05, dated March 16, 2005. These service bulletins
describe procedures for installing an aileron damper and modifying the
hydraulic system, among other actions.
6. Subtask 27-12-01-212-002-A00 of the EMBRAER EMB-145 Aircraft
Maintenance Manual. This subtask provides procedures for inspecting the
aileron PCA rod ends and fitting lugs.
The DAC mandated the service information and issued Brazilian
airworthiness directive 1999-02-01R6, dated June 21, 2004, to ensure
the continued airworthiness of these airplanes in Brazil.

FAA's Determination and Requirements of the Proposed AD

These airplane models are manufactured in Brazil and are type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the DAC has kept the FAA informed of
the situation described above. We have examined the DAC's findings,
evaluated all pertinent information, and determined that AD action is
necessary for airplanes of this type design that are certificated for
operation in the United States.
This proposed AD would supersede AD 99-05-04 and would continue to
require repetitive inspections to detect cracking or failure of the rod
ends of the aileron PCA, and corrective actions if necessary. This
proposed AD would also:
1. Require the same repetitive inspections of additional P/Ns at
new inspection intervals for certain airplanes;
2. Provide new corrective actions;
3. Require use of a new revision of the previously required service
bulletin; and
4. Provide an optional terminating action for the proposed
requirements.
The proposed AD would require you to use the service information
described previously to perform these actions.

Differences Between the Proposed AD and the Brazilian Airworthiness
Directive

The Brazilian airworthiness directive does not give a compliance
time for the initial inspection of the PCA rod ends and fittings. We
would require that inspection to be done at the applicable time
specified in the following table, ``Compliance Times for Initial
Inspection.'' In developing an appropriate compliance time for this
inspection, we considered the manufacturer's recommendation, the degree
of urgency associated with the subject unsafe condition, the average
utilization of the affected fleet, and the time necessary to perform
the inspection (1 hour). We also considered that the referenced service
bulletin (EMBRAER Service Bulletin 145-27-0054, Change 03, dated March
30, 2000), which contains the procedures for accomplishing the required
inspection, has been available to all operators of the subject EMBRAER
airplanes since March 2000. (EMBRAER Service Bulletin 145-27-0054,
Change 03, was revised on February 14, 2005, to add two airplanes to
the effectivity; we understand that the actions specified in the
service bulletin have been accomplished on those two airplanes.) In
light of all of these factors, we find that the initial inspection must
be accomplished at the applicable time specified in the table below,
which represents an appropriate interval of time allowable for affected
airplanes to continue to operate without compromising safety.

Table.--Compliance Times for Initial Inspection
------------------------------------------------------------------------
For airplanes that have PCAs with these
part numbers (P/N)-- Do the initial inspection--
------------------------------------------------------------------------
394900-1003 or 394900-1005............. Within 3 days after the
effective date of this AD.
394900-1007............................ Within 14 days after the
effective date of this AD.
418800-1001, 418800-1003, 418800-9003, Within 500 flight hours after
418800-1005, 418800-9005, 418800-1007, the effective date of this AD.
or 418800-9007; and that have new
reinforced PCA fittings installed in
accordance with paragraph (k) or (l)
of this AD.
------------------------------------------------------------------------

[[Page 72728]]

The Brazilian airworthiness directive also does not give a
compliance time for replacing cracked or failed PCA fittings or rod
ends. This proposed AD would require replacing any cracked or failed
part before further flight.
In addition, the Brazilian airworthiness directive does not specify
what operators should do when no cracked or failed aileron PCA rod ends
or connecting fittings are found. This AD would require the inspection
to be repeated at the intervals specified in the following table.

Table.--Repeat Inspection Intervals
------------------------------------------------------------------------
For airplanes that have PCAs with these
part numbers (P/N)-- Repeat the inspection--
------------------------------------------------------------------------
394900-1003 or 394900-1005............. At intervals not to exceed 25
flight hours or 3 days,
whichever occurs later.
394900-1007............................ At intervals not to exceed 100
flight hours or 14 days,
whichever occurs later.
418800-1001, 418800-1003, 418800-9003, At intervals not to exced 500
418800-1005, 418800-9005, 418800-1007, flight hours.
or 418800-9007; and that have new
reinforced PCA fittings installed in
accordance with paragraph (j) or (k)
of this AD.
------------------------------------------------------------------------

These differences have been coordinated with the DAC and they are
in agreement.

Change to Existing AD

This proposed AD would retain certain requirements of AD 99-05-04.
Since AD 99-05-04 was issued, the AD format has been revised, and
certain paragraphs have been rearranged. As a result, the corresponding
paragraph identifiers have changed in this proposed AD, as listed in
the following table:

Revised Paragraph Identifiers
------------------------------------------------------------------------
Corresponding requirement in
Requirement in AD 99-05-04 this proposed AD
------------------------------------------------------------------------
Paragraph (a)............................. Paragraph (f).
Paragraph (b)............................. Paragraph (g).
------------------------------------------------------------------------

In addition, all references to a ``detailed visual inspection''
have been changed to refer to a ``detailed inspection.'' A definition
of detailed inspection is included in Note 1 of the proposed AD.
We have also removed the requirement in paragraph (c) of AD 99-05-
04 to send a report of any cracked or failed rod end to the Manager,
Atlanta Aircraft Certification Office, FAA. We no longer need this
information from operators.

Interim Action

We consider this proposed AD interim action. If final action is
later identified, we may consider further rulemaking then.

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

[[Page 72729]]

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

List of Subjects in 14 CFR Part 39

AD performed within the compliance times specified, unless the
actions have already been done.

Restatement of Certain Requirements of AD 99-05-04

Initial and Repetitive Inspections

(f) Within 24 hours (1 day) after March 29, 1999 (the effective
date of AD 99-05-04), perform a detailed inspection to detect
cracking or failure of the rod ends of the PCA at the aileron and
wing connection points, in accordance with EMBRAER Alert Service
Bulletin 145-27-A054, Change 01, dated February 17, 1999; or EMBRAER
Service Bulletin 145-27-0054, Change 03, dated March 30, 2000, or
Change 04, dated February 14, 2005. Repeat the inspection in
accordance with the service bulletin thereafter at intervals not to
exceed 3 days or 25 flight hours, whichever occurs later, until the
initial inspection required by paragraph (h) of this AD is done.

Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''
