DEPARTMENT OF TRANSPORTATION
14 CFR Part 39
[Docket No. 94-NM-129-AD; Amendment 39-9367; AD 95-19-05]
Airworthiness Directives; British Aerospace Model BAe 146-100A
and -200A 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 146-100A and -200A
airplanes, that requires modification of the glareshield and certain
electrical equipment of the airplane. This amendment is prompted by a
report indicating that, if the lift spoilers fail to deploy on landing,
the flight crew may not receive any indication that this situation
exists. The actions specified by this AD are intended to ensure that
the flight crew is advised when the lift spoilers fail to deploy on
landing; such failure could result in the airplane overrunning the end
of the runway during landing.
DATES: Effective October 20, 1995.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of October 20, 1995.
ADDRESSES: The service information referenced in this AD may be
obtained from Avro International Aerospace, Inc., 22111 Pacific Blvd.,
Sterling, Virginia 20166. 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.

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 146-100A and -200A airplanes was published in the Federal Register
on May 18, 1995 (60 FR 26702). That action proposed to require
modification of the glareshield and certain electrical equipment of the
airplane.
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 38 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 21 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
$6,000 per airplane. Based on these figures, the total cost impact of
the AD on U.S. operators is estimated to be $275,880, or $7,260 per
airplane.
The total 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.
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 USC 106(g), 40101, 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
95-19-05 British Aerospace Regional Aircraft Limited, AVRO
International Aerospace Division (Formerly British Aerospace, plc;
British Aerospace Commercial Aircraft Limited): Amendment 39-9367.
Docket 94-NM-129-AD.
Applicability: Model BAe 146-100A and -200A airplanes; as listed
in British Aerospace Service Bulletin SB.27-70-00913A&B, Revision 7,
dated March 21, 1994; 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 use the authority
provided in paragraph (b) 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 ensure that the flight crew is advised when the lift spoilers
fail to deploy on landing, accomplish the following:
(a) Within 18 months after the effective date of this AD, modify
the glareshield and certain electrical equipment of the airplane by
installing an amber warning light in the glareshield that will
illuminate if the lift spoilers fail to deploy on landing; perform a
test of the glareshield warning light; and perform a lift spoiler
inhibit and fault monitoring operational test; in accordance with
British Aerospace Service Bulletin SB.27-70-00913A&B, Revision 7,
dated March 21, 1994.
(b) 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 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Standardization Branch, ANM-113.
(c) 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.
(d) The modification shall be done in accordance with British
Aerospace Service Bulletin SB.27-70-00913A&B, Revision 7, dated
March 21, 1994, which contains the specified effective pages:
