ACTION: Final rule; request for comments. pwalker on PROD1PC71 with RULES AGENCY: SUMMARY: This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2007–06–53 that was sent previously to all known U.S. owners and operators of EMBRAER Model ERJ 170 and ERJ 190 airplanes by individual notices. This AD requires repetitively verifying the correct closure of the forward and aft cargo doors, inspecting the forward and aft cargo doors for interference between the lock handle and the aft edge liner assembly, repetitively inspecting the lateral roller fittings on the forward and aft cargo door frames for damage, and doing corrective actions if needed. This AD also requires reporting any signs of interference or damage to the manufacturer. This AD results from a report indicating that the aft cargo door opened in flight just after departure, and from a report indicating that an airplane was dispatched with an unsecured forward cargo door. We are issuing this AD to prevent a cargo door from opening during flight, which could lead to structural failure or loss of control. DATES: This AD becomes effective May 7, 2007 to all persons except those persons to whom it was made immediately effective by emergency AD 2007–06–53, issued March 19, 2007, which contained the requirements of this amendment. The incorporation by reference of certain publications listed in the AD is approved by the Director of the Federal Register as of May 7, 2007. We must receive comments on this AD by June 29, 2007.

FOR FURTHER INFORMATION CONTACT: On March 19, 2007, we issued emergency AD 2007–06–53, which applies to all EMBRAER Model ERJ 170 and ERJ 190 airplanes. SUPPLEMENTARY INFORMATION: Background The FAA received a report that the aft cargo door of a Model ERJ 190 airplane opened in flight just after takeoff. The airplane returned to the departure airport and landed without incident. We ˆ advised the Agencia Nacional de Aviacao Civil (ANAC), which is the ¸˜ airworthiness authority for Brazil, of the report and worked closely with the ANAC to assess the safety implications of the report. The assessment of the event indicated that the door was not fully closed when the airplane took off. Inspection of the airplane revealed that the door frame lateral roller fitting was cracked and the roller fitting cover plate was distorted. The roller fitting cover plate distortion caused a malfunction in the door position indication system. A similar situation was found on the forward cargo door on a Model ERJ 170 airplane. In that instance, the problem was discovered by ground personnel, and the door was secured prior to takeoff. The cargo door design is the same for the Model ERJ 190 and ERJ 170 airplanes. Therefore, an unsafe condition may exist on all EMBRAER Model ERJ 170 and ERJ 190 airplanes. We are issuing this AD to prevent a cargo door from opening during flight, which could lead to structural failure or loss of control. PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 Relevant Service Information EMBRAER has issued Alert Service Bulletins 170–52–A036 (for Model ERJ 170 airplanes) and 190–52–A018 (for Model ERJ 190 airplanes), both dated March 12, 2007. The alert service bulletins describe the following procedures: • Removal of the roller fitting cover plate; • A one-time visual inspection of the forward and aft cargo doors to detect signs of interference between the lock handle and the aft edge liner assembly; • Rework of the aft edge liner assembly, which must be done immediately if there are signs of interference, and may be deferred for a specified time if there are no signs of interference; • A one-time visual inspection of the forward and aft cargo doors to detect signs of damage of the lateral roller fitting; and • Immediate replacement of any damaged fitting with one having the same part number. The ANAC mandated the actions in the alert service bulletins and issued Brazilian airworthiness directives 2007– 03–01 and 2007–03–02, both effective March 16, 2007, to ensure the continued airworthiness of these airplanes in Brazil. The alert service bulletins refer to EMBRAER Service Bulletins 170–50– 0006 and 190–50–0006 as additional sources of service information for removing the roller fitting cover plate and reworking the aft edge liner assembly. These service bulletins are currently at Revision 01, dated March 13, 2007. FAA’s Determination and Requirements of This 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 ANAC has kept the FAA informed of the situation described above. We have examined the ANAC’s findings, evaluated all pertinent information, and determined that we need to issue an AD for products of this type design that are certificated for operation in the United States. Since the unsafe condition described is likely to exist or develop on other airplanes of the same type design, we issued emergency AD 2007–06–53 to prevent a cargo door from opening E:\FR\FM\30APR1.SGM 30APR1 Federal Register / Vol. 72, No. 82 / Monday, April 30, 2007 / Rules and Regulations during flight; the door could detach from and strike the airplane and result in structural damage and possible loss of control of the airplane. The AD requires accomplishing the actions specified in the service information previously described. This AD also requires repetitively verifying, before each flight, the correct closure of the forward and aft cargo doors, and reporting positive inspection results to EMBRAER. We found that immediate corrective action was required; therefore, notice and opportunity for prior public comment thereon were impracticable and contrary to the public interest, and good cause existed to make the AD effective immediately by individual notices issued on March 19, 2007, to all known U.S. owners and operators of EMBRAER Model ERJ 170 and ERJ 190 airplanes. These conditions still exist, and the AD is hereby published in the Federal Register as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13) to make it effective to all persons. Clarification of Qualifications for Performing Preflight Verifications This AD permits the preflight verifications to be done by mechanics and flightcrew members. We have determined that this provision will accommodate operators’ maintenance scheduling demands and yet ensure an acceptable level of safety. Explanation of Reporting Requirement This AD also requires that operators report the results of positive inspection findings to EMBRAER. The required inspection reports will help determine the extent in the fleet of potentially contributing conditions. Based on the results of these reports, we might determine that further corrective action is warranted. pwalker on PROD1PC71 with RULES Interim Action We consider this AD interim action. The manufacturer is currently developing a modification to the door position sensing system that will further address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, we might consider additional rulemaking.

Comments will be available in the AD docket shortly after the Docket Management System receives them. 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. PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 21089 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. The FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and that it is not a ‘‘significant regulatory action’’ under Executive Order 12866. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If this emergency regulation is later deemed significant under DOT Regulatory Policies and Procedures, we will prepare a final regulatory evaluation and place it in the AD Docket. See the ADDRESSES section for a location to examine the regulatory evaluation, if filed.

SUPPLEMENTARY INFORMATION: On March 19, 2007, we issued emergency AD 
2007-06-53, which applies to all EMBRAER Model ERJ 170 and ERJ 190 
airplanes.

Background

    The FAA received a report that the aft cargo door of a Model ERJ 
190 airplane opened in flight just after takeoff. The airplane returned 
to the departure airport and landed without incident. We advised the 
Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), which is 
the airworthiness authority for Brazil, of the report and worked 
closely with the ANAC to assess the safety implications of the report. 
The assessment of the event indicated that the door was not fully 
closed when the airplane took off. Inspection of the airplane revealed 
that the door frame lateral roller fitting was cracked and the roller 
fitting cover plate was distorted. The roller fitting cover plate 
distortion caused a malfunction in the door position indication system. 
A similar situation was found on the forward cargo door on a Model ERJ 
170 airplane. In that instance, the problem was discovered by ground 
personnel, and the door was secured prior to takeoff. The cargo door 
design is the same for the Model ERJ 190 and ERJ 170 airplanes. 
Therefore, an unsafe condition may exist on all EMBRAER Model ERJ 170 
and ERJ 190 airplanes. We are issuing this AD to prevent a cargo door 
from opening during flight, which could lead to structural failure or 
loss of control.

Relevant Service Information

    EMBRAER has issued Alert Service Bulletins 170-52-A036 (for Model 
ERJ 170 airplanes) and 190-52-A018 (for Model ERJ 190 airplanes), both 
dated March 12, 2007. The alert service bulletins describe the 
following procedures:
     Removal of the roller fitting cover plate;
     A one-time visual inspection of the forward and aft cargo 
doors to detect signs of interference between the lock handle and the 
aft edge liner assembly;
     Rework of the aft edge liner assembly, which must be done 
immediately if there are signs of interference, and may be deferred for 
a specified time if there are no signs of interference;
     A one-time visual inspection of the forward and aft cargo 
doors to detect signs of damage of the lateral roller fitting; and
     Immediate replacement of any damaged fitting with one 
having the same part number.
    The ANAC mandated the actions in the alert service bulletins and 
issued Brazilian airworthiness directives 2007-03-01 and 2007-03-02, 
both effective March 16, 2007, to ensure the continued airworthiness of 
these airplanes in Brazil.
    The alert service bulletins refer to EMBRAER Service Bulletins 170-
50-0006 and 190-50-0006 as additional sources of service information 
for removing the roller fitting cover plate and reworking the aft edge 
liner assembly. These service bulletins are currently at Revision 01, 
dated March 13, 2007.

FAA's Determination and Requirements of This 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 ANAC has kept the FAA informed 
of the situation described above. We have examined the ANAC's findings, 
evaluated all pertinent information, and determined that we need to 
issue an AD for products of this type design that are certificated for 
operation in the United States.
    Since the unsafe condition described is likely to exist or develop 
on other airplanes of the same type design, we issued emergency AD 
2007-06-53 to prevent a cargo door from opening

[[Page 21089]]

during flight; the door could detach from and strike the airplane and 
result in structural damage and possible loss of control of the 
airplane. The AD requires accomplishing the actions specified in the 
service information previously described. This AD also requires 
repetitively verifying, before each flight, the correct closure of the 
forward and aft cargo doors, and reporting positive inspection results 
to EMBRAER.
    We found that immediate corrective action was required; therefore, 
notice and opportunity for prior public comment thereon were 
impracticable and contrary to the public interest, and good cause 
existed to make the AD effective immediately by individual notices 
issued on March 19, 2007, to all known U.S. owners and operators of 
EMBRAER Model ERJ 170 and ERJ 190 airplanes. These conditions still 
exist, and the AD is hereby published in the Federal Register as an 
amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 
39.13) to make it effective to all persons.

Clarification of Qualifications for Performing Preflight Verifications

    This AD permits the preflight verifications to be done by mechanics 
and flightcrew members. We have determined that this provision will 
accommodate operators' maintenance scheduling demands and yet ensure an 
acceptable level of safety.

Explanation of Reporting Requirement

    This AD also requires that operators report the results of positive 
inspection findings to EMBRAER. The required inspection reports will 
help determine the extent in the fleet of potentially contributing 
conditions. Based on the results of these reports, we might determine 
that further corrective action is warranted.

Interim Action

    We consider this AD interim action. The manufacturer is currently 
developing a modification to the door position sensing system that will 
further address the unsafe condition identified in this AD. Once this 
modification is developed, approved, and available, we might consider 
additional rulemaking.

Comments Invited

    This AD is a final rule that involves requirements that affect 
flight safety and was not preceded by notice and an opportunity for 
public comment; however, we invite you to submit any relevant written 
data, views, or arguments regarding this AD. Send your comments to an 
address listed in the ADDRESSES section. Include ``Docket No. FAA-2007-
27616; Directorate Docket No. 2007-NM-052-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the AD that might 
suggest a need to modify it.
    We will post all comments we receive, without change, to https://
dms.dot.gov, including any personal information you provide. We will 
also post a report summarizing each substantive verbal contact with FAA 
personnel concerning this AD. Using the search function of that Web 
site, anyone can find and read the comments in any of our dockets, 
including the name of the individual who sent the comment (or signed 
the comment on behalf of an association, business, labor union, etc.).

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 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.
    The FAA has determined that this regulation is an emergency 
regulation that must be issued immediately to correct an unsafe 
condition in aircraft, and that it is not a ``significant regulatory 
action'' under Executive Order 12866. It has been determined further 
that this action involves an emergency regulation under DOT Regulatory 
Policies and Procedures (44 FR 11034, February 26, 1979). If this 
emergency regulation is later deemed significant under DOT Regulatory 
Policies and Procedures, we will prepare a final regulatory evaluation 
and place it in the AD Docket. See the ADDRESSES section for a location 
to examine the regulatory evaluation, if filed.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2007-06-53 Empresa Brasileira de Aeronautica S.A. (EMBRAER): 
Amendment 39-15035. Docket No. FAA-2007-27616; Directorate 
Identifier 2007-NM-052-AD.

Effective Date

    (a) This AD becomes effective May 7, 2007, to all persons except 
those persons to whom it was made immediately effective by emergency 
AD 2007-06-53, issued on March 19, 2007, which contained the 
requirements of this amendment.

Affected ADs

    (b) None.

[[Page 21090]]

Applicability

    (c) This AD applies to all EMBRAER Model ERJ 170-100 LR, -100 
STD, -100 SE, -100 SU, -200 LR, -200 STD, and -200 SU airplanes; and 
ERJ 190-100 STD, -100 LR, and -100 IGW airplanes; certificated in 
any category.

Unsafe Condition

    (d) This AD results from a report indicating that the aft cargo 
door of a Model ERJ 190 airplane opened in flight just after 
departure, and from a report indicating that a Model ERJ 170 
airplane dispatched with an unsecured forward cargo door. The 
Federal Aviation Administration is issuing this AD to prevent a 
cargo door from opening during flight, which could lead to 
structural failure or loss of control.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Preflight Verifications of Correct Door Closure

    (f) As of 24 hours after the effective date of this AD: Before 
each flight after closing the cargo doors, verify that the forward 
and aft cargo doors are closed flush with the fuselage skin, and 
that all 4 latched and locked indicators at the bottom of each door 
are green. Persons qualified to do this verification are mechanics 
and flightcrew members. If it cannot be verified that both doors are 
closed flush with the fuselage skin, and that all 4 latched and 
locked indicators at the bottom of each door are green, repair 
before further flight. Repeat the verification before every flight 
until accomplishment of the actions required by paragraph (g) of 
this AD.

Inspection for Interference and Damage

    (g) Within 10 days after the effective date of this AD, do the 
actions specified in paragraphs (g)(1), (g)(2), and (g)(3) of this 
AD, in accordance with the Accomplishment Instructions of EMBRAER 
Alert Service Bulletin 170-52-A036 (for Model ERJ 170 airplanes) or 
190-52-A018 (for Model ERJ 190 airplanes), both dated March 12, 
2007, as applicable.
    (1) Remove the roller fitting cover plate on the forward and aft 
cargo door frames.
    (2) Perform a detailed inspection of the forward and aft cargo 
doors to detect signs of interference between the lock handle and 
the aft edge liner assembly. Then rework the aft edge liner assembly 
at the applicable time specified in paragraph (g)(2)(i) or 
(g)(2)(ii) of this AD.
    (i) If any sign of interference is detected: Rework the assembly 
before further flight.
    (ii) If no sign of interference is detected: Rework the assembly 
within 150 flight cycles after the inspection.
    (3) Perform a detailed inspection for signs of damage of the 
lateral roller fitting on the forward and aft cargo door frames at 
the fuselage. If any damage is found, replace the lateral roller 
fitting before further flight with a new roller fitting having the 
same part number, in accordance with the applicable service 
bulletin.

    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.''
