[Docket No. 98-CE-70-AD; Amendment 39-10825; AD 98-21-16]
RIN 2120-AA64
Airworthiness Directives; British Aerospace HP137 Mk1, Jetstream
Series 200, and Jetstream Models 3101 and 3201 Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Direct final rule; withdrawal.
-----------------------------------------------------------------------
SUMMARY: This action withdraws direct final rule Airworthiness
Directive (AD) 98-21-16, which would have applied to all British
Aerospace (BAe) HP137 Mk1, Jetstream Series 200, and Jetstream Models
3101 and 3201 airplanes; and would have superseded AD 98-12-23 (this AD
will remain in effect, unless the Federal Aviation Administration (FAA)
initiates additional rulemaking action). AD 98-21-16 would have
required repetitively replacing the windshield wiper arm, attachment
bolts, and assembly; measuring the material thickness of the upper and
lower toggle attachment brackets on the nose landing gear of the
affected airplanes, and replacing the toggle attachment bracket lugs.
Since the issuance of the direct final rule, the FAA has received a
written adverse comment. Accordingly, the direct final rule is
withdrawn.

SUPPLEMENTARY INFORMATION: The FAA published AD 98-21-16 as a direct
final rule with request for comments in the Federal Register on October
8, 1998 (63 FR 54039). That direct final rule amended part 39 of the
Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to all BAe HP137 Mk1, Jetstream Series 200, and Jetstream
Models 3101 and 3201 airplanes. That AD would have superseded AD 98-12-
23 with a new AD to require repetitively replacing the windshield wiper
arm, attachment bolts, and assembly; measuring the material thickness
of the upper and lower toggle attachment brackets on the nose landing
gear of the affected airplanes, and replacing the toggle attachment
bracket lugs.
AD 98-21-16 was the result of additional mandatory continuing
airworthiness information (MCAI) pertaining to this subject received
from the airworthiness authority for the United Kingdom. The actions
specified in that AD were intended to prevent the windshield wiper arm
from corroding, detaching from the airplane during flight, and
penetrating the fuselage, which could result in possible injury to the
pilot and passengers; and to prevent collapse of the nose landing gear
caused by the current design, which could result in loss of control of
the airplane during landing operations.
The Direct Final Rule Procedure
The FAA anticipated that AD 98-21-16 would not result in adverse or
negative comment and therefore issued it as a direct final rule. The
requirements of AD 98-21-16 addressed an unsafe condition identified by
a foreign civil airworthiness authority and do not impose a significant
burden on affected operators. In accordance with Section 11.17 of the
Federal Aviation Regulations (14 CFR 11.17), unless a written adverse
or negative comment or a written notice of intent to submit an adverse
or negative comment was received within the comment period, AD 98-21-16
would have become effective on January 6, 1999. If any written
comment(s) was received within the comment period that was adverse or
negative comment or written notice was received of the intent to submit
such a comment, the FAA would publish in the Federal Register a
document withdrawing the direct final rule (AD 98-21-16). The FAA could
then issue a notice of proposed rulemaking with a new comment period.
Actions Since the Issuance of the Direct Final Rule
During the comment period for the 98-21-16, the FAA received a
written adverse comment. The commenter objects to the 90-day repetitive
replacement requirement of the windshield wiper arm attachment bolt and
windshield arm assembly. The commenter suggests that these replacements
occur at 8 year intervals as specified in the service information.
Accordingly, the direct final rule is hereby withdrawn.
Withdrawal of this direct final rule constitutes only such action,
and does not preclude the agency from issuing a notice in the future,
nor does it commit the agency to any course of action in the future.
Regulatory Impact
Since this action only withdraws a direct final rule, it has no
adverse economic impact and imposes no additional burden on any person.
It will have no 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 action does not have sufficient federalism
implications to warrant the preparation of a Federalism Assessment.
For the reasons discussed above, I certify that this action 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.
