Federal Aviation Administration
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)
