Airworthiness Directives; British Aerospace Model BAe Avro 146-RJ
Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain British Aerospace Model BAe Avro 146-RJ series
airplanes, that requires a one-time inspection of certain electrical
wires in the electrical equipment bay to determine if ERMA terminal
lugs are installed; and replacement with new parts, if necessary. This
amendment is prompted by issuance of mandatory continuing airworthiness
information by a foreign civil airworthiness authority. The actions
specified by this AD are intended to prevent failure of the electrical
circuit terminal lugs, which could result in electrical system failure,
and consequent reduced controllability of the airplane.
DATES: Effective July 8, 1998.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of July 8, 1998.
ADDRESSES: The service information referenced in this AD may be
obtained from AI(R) American Support, Inc., 13850 Mclearen Road,
Herndon, Virginia 20171. 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: Norman B. Martenson, Manager,
International Branch, ANM-116, FAA, Transport Airplane Directorate,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain British Aerospace Model
BAe Avro 146-RJ series airplanes was published in the Federal Register
on April 2, 1998 (63 FR 16175). That action proposed to require a one-
time inspection of certain electrical wires in the electrical equipment
bay to determine if ERMA terminal lugs are installed; and replacement
with new parts, if necessary.
Comments
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.
Conclusion
The FAA has determined that air safety and the public interest
require the adoption of the rule as proposed.
Cost Impact
The FAA estimates that 1 airplane of U.S. registry will be affected
by this AD, that it will take approximately 4 work hours per airplane
to accomplish the required inspection, and that the average labor rate
is $60 per work hour. Based on these figures, the cost impact of this
AD on the single U.S. operator is estimated to be $240.
The cost impact figure discussed above is 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.
Regulatory Impact
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

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. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
98-11-28 British Aerospace Regional Aircraft (Formerly British
Aerospace Regional Aircraft Limited, Avro International Aerospace
Division; British Aerospace, PLC; British Aerospace Commercial
Aircraft Limited): Amendment 39-10553. Docket 98-NM-43-AD.
Applicability: Model BAe Avro 146-RJ85A series airplanes, serial
numbers E2296, E2297, E2299, E2300, E2302, E2303, E2304, E2305,
E2306, and E2307; and Model Avro 146-RJ100A series airplanes, serial
numbers E3298, E3301, and E3308; 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 (c) 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 prevent failure of the electrical circuit terminal lugs,
which could result in electrical system failure, and consequent
reduced controllability of the airplane, accomplish the following:
(a) Within 6 months after the effective date of this AD, perform
a one-time visual inspection of the electrical wires, having part
numbers (P/N) MD0011N and MD0012N, in the electrical equipment bay
and hydraulic equipment bay, to determine if any ERMA terminal lug
having P/N ERMA 12115/2 is installed, in accordance with British
Aerospace Service Bulletin SB.24-120, dated September 18, 1997. If
any ERMA terminal lug is found, prior to further flight, remove the
lug and replace with an AMP terminal lug having P/N AMP 323064, in
accordance with the service bulletin.
(b) As of the effective date of this AD, no person shall install
an ERMA terminal lug, P/N ERMA 12115/2, on any airplane.
(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, International Branch, ANM-116, 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, International
Branch, ANM-116.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the International Branch, ANM-116.
(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 inspection and replacement shall be done in accordance
with British Aerospace Service Bulletin SB.24-120, dated September
18, 1997. 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 AI(R) American
Support, Inc., 13850 Mclearen Road, Herndon, Virginia 20171. Copies
may be inspected at the FAA, Transport Airplane Directorate, 1601
Lind Avenue, SW., Renton, Washington; or at the Office of the
Federal Register, 800 North Capitol Street, NW., suite 700,
Washington, DC.
Note 3: The subject of this AD is addressed in British
airworthiness directive 007-09-97.
(f) This amendment becomes effective on July 8, 1998.
