14 CFR Part 39

[Docket No. 94-NM-186-AD; Amendment 39-9296; AD 95-14-04]


Airworthiness Directives; British Aerospace Model BAC 1-11 200 
and 400 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to certain British Aerospace Model BAC 1-11 200 and 
400 airplanes, that currently requires incorporation of certain 
structural modifications. That AD was prompted by reports of fatigue 
cracking and corrosion in transport category airplanes that are 
approaching or have exceeded their economic design goal. The actions 
specified by that AD are intended to prevent reduced structural 
integrity of the airplane. This amendment requires incorporation of 
additional structural modifications.

DATES: Effective August 7, 1995.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of August 7, 1995.

ADDRESSES: The service information referenced in this AD may be 
obtained from British Aerospace, Airbus Limited, P.O. Box 77, Bristol 
BS99 7AR, England. This information may be examined at the Federal 
Aviation Administration (FAA), Transport Airplane Directorate, Rules 
Docket, 1601 Lind Avenue SW., Renton, Washington; or at the Office of 
the Federal Register, 800 North Capitol Street NW., suite 700, 
Washington, DC.

FOR FURTHER INFORMATION CONTACT: William Schroeder, Aerospace Engineer, 
Standardization Branch, ANM-113, FAA, Transport Airplane Directorate, 
1601 Lind Avenue SW., Renton, Washington 98055-4056; telephone (206) 
227-2148; fax (206) 227-1149.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) by superseding AD 90-23-09, 
amendment 39-6795 (55 FR 46502, November 5, 1990), which is applicable 
to certain British Aerospace Model BAC 1-11 200 and 400 airplanes, was 
published in the Federal Register on April 27, 1995 (60 FR 20661). The 
action proposed to require incorporation of additional structural 
modifications.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public. 
The FAA has determined that air safety and the public interest require 
the adoption of the rule as proposed.
    The FAA estimates that 31 airplanes of U.S. registry will be 
affected by this AD, that it will take approximately 387 work hours per 
airplane to accomplish the required actions, and that the average labor 
rate is $60 per work hour. Required parts will cost approximately 
$10,315 per airplane. Based on these figures, the total cost impact of 
the AD on U.S. operators is estimated to be $1,039,585, or $33,535 per 
airplane.
    The total cost impact figures discussed above are based on 
assumptions that no operator has yet accomplished any of the 
requirements of this AD action, and that no operator would accomplish 
those actions in the future if this AD were not adopted.
    The regulations adopted herein will not have substantial direct 
effects 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, in 
accordance with Executive Order 12612, it is determined that this final 
rule does not have sufficient federalism implications to warrant the 
preparation of a Federalism Assessment.
    For the reasons discussed above, I certify that this action (1) is 
not a ``significant regulatory action'' under Executive Order 12866; 
(2) is not a ``significant rule'' under 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. A final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption 
ADDRESSES.

Adoption of the Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration amends part 39 of 
the Federal Aviation Regulations (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. App. 1354(a), 1421 and 1423; 49 U.S.C. 
106(g); and 14 CFR 11.89.


Sec. 39.13  [Amended]

    2. Section 39.13 is amended by removing amendment 39-6795 (55 FR 
46502, November 5, 1990), and by adding a new airworthiness directive 
(AD), amendment 39-9296, to read as follows:

95-14-04 British Aerospace Airbus Limited (Formerly British 
Aerospace Commercial Aircraft Limited, British Aerospace Aircraft 
Group): Amendment 39-9296. Docket 94-NM-186-AD. Supersedes AD 90-23-
09, Amendment 39-6795.

    Applicability: Model BAC 1-11 200 and 400 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 

[[Page 35323]]
owner/operator must use the authority provided in paragraph (c) of this 
AD to request approval from the FAA. This approval may address 
either no action, if the current configuration eliminates the unsafe 
condition; or different actions necessary to address the unsafe 
condition described in this AD. Such a request should include an 
assessment of the effect of the changed configuration on the unsafe 
condition addressed by this AD. In no case does the presence of any 
modification, alteration, or repair remove any airplane from the 
applicability of this AD.

    Compliance: Required as indicated, unless accomplished 
previously.
    To prevent reduced structural integrity of the airplane, 
accomplish the following:
    (a) Prior to reaching the ``Not Exceed Time'' interval specified 
in Table 1 of British Aerospace Alert Service Bulletin 5-A-PM5995, 
Issue 3, dated March 19, 1993; or within 15 months after the 
effective date of this AD; whichever occurs later: Install the 
structural modification listed in each Item in Table 1 of the alert 
service bulletin, except for Items 6, 11, 13, and 14. The 
modifications shall be done in accordance with the appropriate 
service bulletin specified for each Item in Table 1, listed under 
``Service Bulletin No.''

    Note 2: Items 6, 11, 13, and 14 in Table 1 of British Aerospace 
Alert Service Bulletin 5-A-PM5995, Issue 3, are not included in the 
requirements of this AD since those items are addressed by separate 
rulemaking actions.

    (b) Accomplishment of the modifications required by paragraph 
(a) of this AD constitutes terminating action for the repetitive 
inspections required by the following AD's:

    (c) An alternative method of compliance or adjustment of the 
compliance time that provides an acceptable level of safety may be 
used if approved by the Manager, Standardization Branch, ANM-113, 
FAA, Transport Airplane Directorate. Operators shall submit their 
requests through an appropriate FAA Principal Maintenance Inspector, 
who may add comments and then send it to the Manager, 
Standardization Branch, ANM-113.

    Note 3: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Standardization Branch, ANM-113.

    (d) Special flight permits may be issued in accordance with 
sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate the airplane to a location where 
the requirements of this AD can be accomplished.
    (e) The installation shall be done in accordance with British 
Aerospace Alert Service Bulletin 5-A-PM5995, Issue 3, dated March 
19, 1993. This incorporation by reference was approved by the 
Director of the Federal Register in accordance with 5 U.S.C. 552(a) 
and 1 CFR part 51. Copies may be obtained from British Aerospace, 
Airbus Limited, P.O. Box 77, Bristol BS99 7AR, England. Copies may

Register, 800 North Capitol Street, NW., suite 700, Washington, DC.
    (f) This amendment becomes effective on August 7, 1995.

    Issued in Renton, Washington, on June 23, 1995.
