Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This document publishes in the Federal Register an amendment 
adopting airworthiness directive (AD) 2001-23-51 that was sent 
previously to all known U.S. owners and operators of certain Airbus 
Model A300 B4-600, B4-600R, and F4-600R (collectively called A300-600) 
series airplanes; and Model A310 series airplanes by individual 
notices. This AD requires a one-time detailed visual inspection to 
detect repairs and alterations to, and damage of the vertical 
stabilizer attachment fittings, including the main attachment lugs and 
the transverse (side) load fittings; and the rudder hinge fittings, 
hinge arms, and support fittings for all rudder hinges, and rudder 
actuator support fittings; and repair, if necessary. This AD also 
requires that operators report results of inspection findings to the 
FAA. This action is prompted by an airplane accident shortly after 
takeoff from John F. Kennedy International Airport, Jamaica, New York. 
The actions specified by this AD are intended to prevent failure of the 
vertical stabilizer-to-fuselage attachment fittings or transverse 
(side) load fittings, or rudder-to-vertical stabilizer attachment 
fittings, which could result in loss of the vertical stabilizer and/or 
rudder and consequent loss of control of the airplane.

DATES: Effective December 10, 2001, to all persons except those persons 
to whom it was made immediately effective by emergency AD 2001-23-51,

SUPPLEMENTARY INFORMATION: On November 16, 2001, the FAA issued 
emergency AD 2001-23-51, which is applicable to certain Airbus Model 
A300 B4-600, B4-600R, and F4-600R (collectively called A300-600) series 
airplanes; and Model A310 series airplanes airplanes.

Background

    On November 12, 2001, an Airbus Model A300 B4-605R airplane was 
involved in an accident shortly after takeoff from John F. Kennedy 
International Airport, Jamaica, New York. The cause of the accident is 
under investigation by the National Transportation Safety Board (NTSB). 
Although the NTSB has not determined the cause of the accident, it has 
determined that the vertical stabilizer departed the airplane. In 
addition, the rudder was found separated from the vertical stabilizer.
    The vertical stabilizer on Airbus Model A300-600 series airplanes 
with Airbus Modification 4886 is manufactured of advanced composite 
materials. The vertical stabilizer on Airbus Model A310 series 
airplanes with the same modification is manufactured of the same 
materials. Failure of the vertical stabilizer-to-fuselage attachment 
fittings, transverse (side) load fittings, or rudder-to-vertical 
stabilizer attachment fittings, if not corrected, could result in loss 
of the vertical stabilizer and/or rudder and consequent loss of control 
of the airplane.
    The FAA considers that, before structural failure, it may be 
possible to detect indications of possible failure modes that could 
result in separation of the vertical stabilizer from the airplane. 
These indications include edge delaminations, cracked paint, surface 
distortions, other surface damage, and failure of the transverse (side) 
load fittings. Similarly, indications of failure of the rudder 
assembly, which could lead to failure of the vertical stabilizer, may 
also be detectable with such an inspection. Although neither the FAA 
nor the NTSB have reached conclusions with respect to these possible 
failures on the accident airplane, we consider it prudent to require an 
inspection of these structures to identify any such indication that may 
exist.
    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. The FAA has 
coordinated this action with the Direction Generale de l'Aviation 
Civile (DGAC), which is the airworthiness authority for France, and the 
DGAC has taken similar action.

Explanation of the Requirements of the Rule

    Since the unsafe condition described is likely to exist or develop 
on other airplanes of the same type design registered in the United 
States, the FAA issued emergency AD 2001-23-51 to prevent failure of 
the vertical stabilizer-to-fuselage attachment fittings or transverse 
(side) load fittings, or rudder-to-vertical stabilizer attachment 
fittings, which could result in loss of the vertical stabilizer and/or 
rudder and consequent loss of control of the airplane. The AD requires 
a one-time detailed visual inspection to detect repairs and alterations 
to, and damage of the vertical stabilizer attachment fittings, 
including the main attachment lugs and the transverse (side) load 
fittings; and the rudder hinge fittings, hinge arms, and support 
fittings for all rudder hinges, and rudder actuator support fittings; 
and repair, if necessary. Damage of the metallic areas includes pulled 
or loose fasteners, wear areas, distorted flanges, cracks, and 
corrosion. Damage of the composite areas includes delamination; 
distorted surfaces that may indicate delamination; cracks in the paint 
surface; evidence of moisture damage; and cracked, splitting, or frayed 
fibers. This AD also requires that operators report results of 
inspection findings to the FAA.

Interim Action

    This is considered to be interim action. The inspection report that 
is required by this AD will enable the FAA, DGAC, and manufacturer to 
obtain better insight into the potential unsafe condition, and 
eventually to develop final action to address it, if necessary. If 
final action is identified, the FAA may consider further rulemaking.

Determination of Rule's Effective Date

    Since it was found that immediate corrective action was required, 
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 November 16, 2001, to all known U.S. owners and operators of 
certain Airbus Model A300 B4-600, B4-600R, and F4-600R (collectively 
called A300-600) series airplanes; and Model A310 series 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 as to all 
persons.

Comments Invited

    Although this action is in the form of a final rule that involves 
requirements affecting flight safety and, thus, was not preceded by 
notice and an opportunity for public comment, comments are invited on 
this rule. Interested persons are invited to comment on this rule by 
submitting such written data, views, or arguments as they may desire. 
Communications shall identify the Rules Docket number and be submitted 
in triplicate to the address specified under the caption ADDRESSES. All 
communications received on or before the closing date for comments will 
be considered, and this rule may be amended in light of the comments 
received. Factual information that supports the commenter's ideas and 
suggestions is extremely helpful in evaluating the effectiveness of the 
AD action and determining whether additional rulemaking action would be 
needed.
    Comments are specifically invited on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify the rule. All comments submitted will be 
available, both before and after the closing date for comments, in the 
Rules Docket for examination by interested persons. A report that

[[Page 63156]]

summarizes each FAA-public contact concerned with the substance of this 
AD will be filed in the Rules Docket.
    Commenters wishing the FAA to acknowledge receipt of their comments 
submitted in response to this rule must submit a self-addressed, 
stamped postcard on which the following statement is made: ``Comments 
to Docket Number 2001-NM-349-AD.'' The postcard will be date stamped 
and returned to the commenter.

Regulatory Impact

    The regulations adopted herein 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. Therefore, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    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 it is 
determined that this emergency regulation otherwise would be 
significant under DOT Regulatory Policies and Procedures, a final 
regulatory evaluation will be prepared and placed in the Rules Docket. 
A copy of it, if filed, may be obtained from the Rules Docket at the 
location provided under the caption ADDRESSES.
