RIN 2120-AA64
Airworthiness Directives; Bombardier Model CL-215-6B11 (CL-415
Variant) Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Direct final rule; withdrawal.
-----------------------------------------------------------------------
SUMMARY: This action withdraws a direct final rule with request for
comments that adopted a new airworthiness directive (AD), applicable to
all Bombardier Model CL-215-6B11 (CL-415 Variant) series airplanes.
That action would have required revising the Airplane Flight Manual
(AFM) to provide the flightcrew with procedures to address a temporary
loss of battery bus power during engine failure and consequent
erroneous indications of hydraulic system pressure, brake pressure,
rudder pressure, and rudder and elevator reversion to manual mode.
Since the issuance of the direct final rule, the Federal Aviation
Administration (FAA) has received a written adverse comment.
Accordingly, the direct final rule is withdrawn.
FOR FURTHER INFORMATION CONTACT: Rodrigo J. Huete, Flight Test Pilot,
Systems and Flight Test Branch, ANE-172, FAA, Engine and Propeller
Directorate, New York Aircraft Certification Office, 10 Fifth Street,
Third Floor, Valley Stream, New York 11581; telephone (516) 256-7518;
fax (516) 568-2716.
SUPPLEMENTARY INFORMATION: The FAA published a direct final rule with
request for comments in the Federal Register on July 9, 1998 (63 FR
37063). That direct final rule amended part 39 of the Federal Aviation
Regulations (14 CFR part 39) to add a new airworthiness directive (AD),
applicable to all Bombardier Model CL-215-6B11 (CL-415 Variant) series
airplanes, to require revising the Airplane Flight Manual (AFM) to
provide the flightcrew with procedures to address a temporary loss of
battery bus power during engine failure and consequent erroneous
indications of hydraulic system pressure, brake pressure, rudder
pressure, and rudder and elevator reversion to manual mode. That action
was prompted by issuance of mandatory continuing airworthiness
information by a foreign civil airworthiness authority. The specified
actions were intended to ensure that the flightcrew is advised of the
potential hazard associated with a temporary loss of battery bus power
during failure of the left engine or the left generator on the left
engine and of the procedures necessary to address it.
Actions Since the Issuance of the Direct Final Rule
During the comment period for the direct final rule, the FAA
received a written adverse comment. Accordingly, the direct final rule
is hereby withdrawn.
Withdrawal of this direct final rule constitutes only such action,
and does
[[Page 48998]]
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 (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.

Docket 98-NM-03-AD, published in the Federal Register on July 9, 1998
