AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule; correction.

SUMMARY:

This document corrects information in an existing airworthiness directive (AD) that applies to all Airbus Model A300; A300-600; and A310 series airplanes. That AD currently requires certain inspections of the airplane (including the vertical stabilizer, horizontal stabilizer, pylons, wing, and fuselage areas) following an in-flight incident resulting in extreme lateral loading. This document clarifies and corrects the information contact in the reporting requirement specified in paragraphs (b)(2) and (c)(2) of that AD. This correction is necessary to ensure that future reports are submitted to a specific point of contact.

DATES:

Effective April 8, 2002.

SUPPLEMENTARY INFORMATION:

On March 15, 2002, the Federal Aviation Administration (FAA) issued AD 2002-06-09, amendment 39-12686 (67 FR 13259, March 22, 2002), which applies to all Airbus Model A300; A300-600; and A310 series airplanes. That AD requires certain inspections of the airplane (including the vertical stabilizer, horizontal stabilizer, pylons, wing, and fuselage areas) following an in-flight incident resulting in extreme lateral loading. The actions required by that AD are intended to detect and correct reduced structural integrity of the airplane following any future event. Start Printed Page 51460

Need for the Correction

Information obtained recently from Airbus Industrie indicates that a specific point of contact should be included for the reporting requirement submissions in that AD.

The FAA has determined that a correction to AD 2002-06-09 is necessary. The correction will replace the reference to AI/SE-D32 Technical Data and Documentation Services and the fax number for that office, as specified in paragraphs (b)(2) and (c)(2) of that AD, with the point of contact Jacques Leborgne and the fax number for that contact.

Correction of Publication

This document corrects the error and correctly adds the AD as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13).

The AD is reprinted in its entirety for the convenience of affected operators. The effective date of the AD remains April 8, 2002.

Since this action only adds a point of contact, it has no adverse economic impact and imposes no additional burden on any person. Therefore, the FAA has determined that notice and public procedures are unnecessary.

End Amendment Part

2002-06-09 Airbus Industrie: Amendment 39-12686. Docket 2002-NM-75-AD.

Applicability: All Model A300; A300 B4-600, B4-600R, and F4-600R (collectively called A300-600); and A310 series airplanes; certificated in any category.

Note 1:

This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (f) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

Compliance: Required as indicated, unless accomplished previously.

To detect and correct reduced structural integrity of the airplane following an extreme lateral loading event, accomplish the following:

Lateral Load Factor Determination

(a) As of the effective date of this AD, before further flight following an in-flight incident that results in extreme lateral loading, determine whether the lateral load factor (Ny) equaled or exceeded 0.3g. Extreme lateral loading can occur as a consequence of severe turbulence, loss of control of the aircraft involving yaw and/or roll maneuvers, hazardous systems failures, or other rare flight conditions. Then do the inspections specified in paragraph (b) or (c) of this AD, as applicable, at the time specified.

Note 2:

Acceptable methods for determining if the lateral load factor equaled or exceeded 0.3g include but are not limited to: Aircraft Communication Addressing and Reporting System (ACARS), Digital Flight Data Recorder (DFDR) readout, or Quick Access Recorder (QAR). A pilot report of extreme lateral acceleration in-flight can be used to assess whether one of the previous methods should be used to determine the lateral load factor.

Note 3:

The inspections specified in paragraphs (b) and (c) of this AD are not necessary if lateral load factors exceed 0.3g when the airplane is on the ground (landing, taxiing).

Inspections for Certain Lateral Load Factors

(b) For airplanes on which the lateral load factor (Ny) is greater than or equal to 0.3g, but less than 0.35g, accomplish the following actions:

(1) Before further flight, do the detailed inspections specified in paragraph (d) of this AD.

Reporting Requirement

(2) Within 5 days after accomplishing the inspections required by paragraph (b)(1) of this AD: Submit a report to Airbus, including the DFDR recording (or equivalent) of the portion of the flight when the extreme lateral loading event occurred, and other relevant information necessary to fully describe the event and develop the actual loads, including but not limited to, airplane weight, weather, and flight crew report. Submit a report of the inspection results (both positive and negative findings) to Jacques Leborgne, Airbus Industrie Customer Services Directorate, 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex France; fax (+33) 5 61 93 36 14.
