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–2005–23007; Directorate Identifier 2005–NM–013–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Model A310–200 and –300 Series Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Model A310–200 and –300 series airplanes. This proposed AD would require repetitive inspections for cracks and corrosion of the areas behind the scuff plates below the passenger/ crew doors and bulk cargo door, and repair of any cracked or corroded part. This proposed AD also would require repetitive inspections for cracks of the holes of the corner doublers, the failsafe ring, and the door frames of the passenger/crew door structures. This proposed AD is prompted by reports of corrosion behind the scuff plates at passenger/crew doors and the bulk cargo door and fatigue cracks on the corner doublers of the forward and aft passenger/crew door frames. We are proposing this AD to prevent such corrosion and fatigue cracking, which could result in reduced structural integrity of the door surroundings. DATES: We must receive comments on this proposed AD by December 21, 2005.

Discussion ´ ´ The Direction Generale de l’Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that an unsafe condition may exist on certain Airbus Model A310–200 and –300 series airplanes. The DGAC advises that it received reports indicating that corrosion was found behind the scuff plates at passenger/ crew doors and the bulk cargo door. The DGAC also advises that results of structural fatigue testing have revealed that cracks were found on the corner doublers of the forward and aft passenger/crew door frames; and, after various simulated flights, on the failsafe ring and frames 14 and 16A of the forward passenger/crew door. After 50,000 simulated flights, cracks measuring between 8.0 millimeters (mm) and 109.0 mm were found on the forward door frames and fail-safe ring. After 60,493 simulated flights, a 53.0 mm crack was found on the mid door frame. After 106,000 simulated flights, a 32.0 mm crack was found on the aft door frame. In all cases, the cracks originated at the fastener holes. In addition, cracks originating from corner doubler edges were found at the aft passenger/crew doors. Such corrosion and fatigue cracking, if not detected and corrected, could result in reduced structural integrity of the door surroundings. E:\FR\FM\21NOP1.SGM 21NOP1 70049 Federal Register / Vol. 70, No. 223 / Monday, November 21, 2005 / Proposed Rules Other Relevant Rulemaking We have previously issued AD 97– 11–03, amendment 39–10032 (62 FR 28325, May 23, 1997), applicable to all Airbus Model A300 series airplanes. That AD requires inspections of the lower door surrounding structure to detect cracks and corrosion; inspections to detect cracking of the holes of the corner doublers, the fail-safe ring, and the door frames of the door structures; and repair if necessary. That AD also requires modification of the passenger/ crew door frames, which terminates certain inspections. We also previously issued AD 98–16– 05, amendment 39–10680 (63 FR 40812, July 31, 1998), applicable to all Airbus Model A300–600 series airplanes. That AD requires inspections of the areas behind the scuff plates below the passenger/crew doors and bulk cargo door to detect cracks and corrosion; inspections to detect cracking of the holes of the corner doublers, the failsafe ring, and the door frames of the door structures; and repair if necessary. In addition, that AD provides for an optional terminating action for certain inspections. We are considering further rulemaking to mandate the optional terminating action. Relevant Service Information Airbus has issued the service bulletins in the following table: SERVICE BULLETINS Airbus Service Bulletin— Describes procedures for— A310–53–2030, Revision 06, dated July 2, 1996 .................................... Doing initial inspections for cracks and corrosion of the areas behind the scuff plates below the passenger/crew doors and bulk cargo door, and repairing any cracked or corroded part. Doing repetitive inspections for cracks and corrosion of the areas behind the scuff plates below the passenger/crew doors and bulk cargo door, and repairing any cracked or corroded part. Doing repetitive inspections for cracks of the holes of the corner doublers, the fail-safe ring, and the door frames of the passenger/crew door structures, and repairing any cracked part. Modifying the passenger/crew door structures, which ends the repetitive inspections of the holes of the corner doublers, fail-safe ring, and the door frames for certain airplanes. The modification includes cold expansion of fastener holes; a ROTO test; installation of new oversize fasteners and modified brackets; and installation of an additional steel doubler. A310–53–2041, Revision 02, dated July 2, 1996 .................................... A310–53–2037, Revision 02, dated November 27, 2000 ........................ A310–53–2017, Revision 09, dated May 17, 2004 .................................. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DGAC mandated the service information and issued French airworthiness directives 1991–132– 124(B) R1, issued November 29, 2000, and F–2004–103, issued July 7, 2004, to ensure the continued airworthiness of these airplanes in France. FAA’s Determination and Requirements of the Proposed AD These airplane models are manufactured in France 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 DGAC has kept the FAA informed of the situation described above. We have examined the DGAC’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. Therefore, we are proposing this AD, which would require accomplishing the applicable actions specified in the service information described previously, except as discussed under ‘‘Differences Between the Proposed AD, French Airworthiness Directive, and Service Bulletins.’’ Differences Between the Proposed AD, French Airworthiness Directive, and Service Bulletins Airbus Service Bulletin A310–53– 2030 also does not list a grace period for certain compliance times. This proposed AD adds a grace period to certain compliance times. We find that a grace period will keep airplanes from being grounded unnecessarily. Airbus Service Bulletins A310–53– 2041 and A310–53–2037 specify repetitive inspections at ‘‘every’’ specified interval; however, this proposed AD would require compliance ‘‘at intervals not to exceed’’ the time specified in the service bulletin. These service bulletins also specify compliance times in ‘‘flights.’’ This proposed AD would specify those times as flight cycles. In addition, Airbus Service Bulletin A310–53–2037 does not specify a starting date for the threshold for the initial inspections. This proposed AD would require compliance before the specified compliance time after the effective date of this AD. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this proposed AD. The average labor rate per hour is $65. ESTIMATED COSTS Action Initial inspections behind scuff plates (for all airplanes). Repetitive inspections behind scuff plates, per inspection cycle (for all airplanes).

Between 8 and 55 depending on kit purchased. 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 0130132. 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. 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 FAA proposes to amend 14 CFR part 39 as follows: Fleet cost Between $11,960, and $149,500 per inspection cycle. Between $47,196 and $444,958. Affected ADs (b) None. Applicability (c) This AD applies to Airbus Model A310– 203, –204, –221, and –222 airplanes; and Airbus Model A310–304, –322, –324, and –325 airplanes; certificated in any category; excluding those airplanes on which Airbus Modification 5068, 7201, and 7298 have been incorporated in production. Unsafe Condition (d) This AD was prompted by reports of corrosion behind the scuff plates at passenger/crew doors and the bulk cargo door and fatigue cracks on the corner doublers of the forward and aft passenger/ crew door frames. We are issuing this AD to prevent such corrosion and fatigue cracking, which could result in reduced structural integrity of the door surroundings.

Airworthiness Directives; Airbus Model A310-200 and -300 Series 
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 Airbus Model A310-200 and -300 series airplanes. This 
proposed AD would require repetitive inspections for cracks and 
corrosion of the areas behind the scuff plates below the passenger/crew 
doors and bulk cargo door, and repair of any cracked or corroded part. 
This proposed AD also would require repetitive inspections for cracks 
of the holes of the corner doublers, the fail-safe ring, and the door 
frames of the passenger/crew door structures. This proposed AD is 
prompted by reports of corrosion behind the scuff plates at passenger/
crew doors and the bulk cargo door and fatigue cracks on the corner 
doublers of the forward and aft passenger/crew door frames. We are 
proposing this AD to prevent such corrosion and fatigue cracking, which 
could result in reduced structural integrity of the door surroundings.

DATES: We must receive comments on this proposed AD by December 21, 
2005.

Discussion

    The Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC), 
which is the airworthiness authority for France, notified us that an 
unsafe condition may exist on certain Airbus Model A310-200 and -300 
series airplanes. The DGAC advises that it received reports indicating 
that corrosion was found behind the scuff plates at passenger/crew 
doors and the bulk cargo door. The DGAC also advises that results of 
structural fatigue testing have revealed that cracks were found on the 
corner doublers of the forward and aft passenger/crew door frames; and, 
after various simulated flights, on the fail-safe ring and frames 14 
and 16A of the forward passenger/crew door. After 50,000 simulated 
flights, cracks measuring between 8.0 millimeters (mm) and 109.0 mm 
were found on the forward door frames and fail-safe ring. After 60,493 
simulated flights, a 53.0 mm crack was found on the mid door frame. 
After 106,000 simulated flights, a 32.0 mm crack was found on the aft 
door frame. In all cases, the cracks originated at the fastener holes. 
In addition, cracks originating from corner doubler edges were found at 
the aft passenger/crew doors.
    Such corrosion and fatigue cracking, if not detected and corrected, 
could result in reduced structural integrity of the door surroundings.

Other Relevant Rulemaking

    We have previously issued AD 97-11-03, amendment 39-10032 (62 FR 
28325, May 23, 1997), applicable to all Airbus Model A300 series 
airplanes. That AD requires inspections of the lower door surrounding 
structure to detect cracks and corrosion; inspections to detect 
cracking of the holes of the corner doublers, the fail-safe ring, and 
the door frames of the door structures; and repair if necessary. That 
AD also requires modification of the passenger/crew door frames, which 
terminates certain inspections.
    We also previously issued AD 98-16-05, amendment 39-10680 (63 FR 
40812, July 31, 1998), applicable to all Airbus Model A300-600 series 
airplanes. That AD requires inspections of the areas behind the scuff 
plates below the passenger/crew doors and bulk cargo door to detect 
cracks and corrosion; inspections to detect cracking of the holes of 
the corner doublers, the fail-safe ring, and the door frames of the 
door structures; and repair if necessary. In addition, that AD provides 
for an optional terminating action for certain inspections. We are 
considering further rulemaking to mandate the optional terminating 
action.

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

Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition. The DGAC mandated 
the service information and issued French airworthiness directives 
1991-132-124(B) R1, issued November 29, 2000, and F-2004-103, issued 
July 7, 2004, to ensure the continued airworthiness of these airplanes 
in France.

FAA's Determination and Requirements of the Proposed AD

    These airplane models are manufactured in France 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 DGAC has kept the FAA informed 
of the situation described above. We have examined the DGAC'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. Therefore, we are proposing this AD, 
which would require accomplishing the applicable actions specified in 
the service information described previously, except as discussed under 
``Differences Between the Proposed AD, French Airworthiness Directive, 
and Service Bulletins.''

Differences Between the Proposed AD, French Airworthiness Directive, 
and Service Bulletins

    Airbus Service Bulletin A310-53-2030 also does not list a grace 
period for certain compliance times. This proposed AD adds a grace 
period to certain compliance times. We find that a grace period will 
keep airplanes from being grounded unnecessarily.
    Airbus Service Bulletins A310-53-2041 and A310-53-2037 specify 
repetitive inspections at ``every'' specified interval; however, this 
proposed AD would require compliance ``at intervals not to exceed'' the 
time specified in the service bulletin. These service bulletins also 
specify compliance times in ``flights.'' This proposed AD would specify 
those times as flight cycles. In addition, Airbus Service Bulletin 
A310-53-2037 does not specify a starting date for the threshold for the 
initial inspections. This proposed AD would require compliance before 
the specified compliance time after the effective date of this AD.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this proposed AD. The average labor rate per hour is 
$65.

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 0130132. 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.

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 FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 401013, 44701.


Sec.  39.13  [Amended]

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

Airbus: Docket No. FAA-2005-23007; Directorate Identifier 2005-NM-
013-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by December 
21, 2005.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A310-203, -204, -221, and -
222 airplanes; and Airbus Model A310-304, -322, -324, and -325 
airplanes; certificated in any category; excluding those airplanes 
on which Airbus Modification 5068, 7201, and 7298 have been 
incorporated in production.

Unsafe Condition

    (d) This AD was prompted by reports of corrosion behind the 
scuff plates at passenger/crew doors and the bulk cargo door and 
fatigue cracks on the corner doublers of the forward and aft 
passenger/crew door frames. We are issuing this AD to prevent such 
corrosion and fatigue cracking, which could result in reduced 
structural integrity of the door surroundings.

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.

Initial Inspections Behind Scuff Plates

    (f) Do initial inspections (i.e., non-destructive tests) for 
cracks and corrosion of the areas behind the scuff plates below the 
passenger/crew doors and bulk cargo door, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A310-53-2030, 
Revision 06, dated July 2, 1996. Do the inspections at the 
applicable time specified in paragraphs (f)(1) and (f)(2) of Table 1 
of this AD. If a records check cannot positively identify if the 
applicable modification or service information specified in 
paragraphs (f)(1) and (f)(2) of this AD has been done, assume that 
it has not.

    Note 1: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''
