[Docket No. 99-NM-261-AD; Amendment 39-11614; AD 2000-05-05]
RIN 2120-AA64
Airworthiness Directives; Construcciones Aeronauticas, S.A.
(CASA) Model CN-235-100 and CN-235-200 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to all CASA Model CN-235-100 and CN-235-200 series
airplanes, that requires replacement of existing anti-icing distributor
valves with new, improved valves. 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 ice accumulation on the wings or tail of the
airplane, which could result in reduced controllability of the
airplane.
DATES: Effective April 12, 2000.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of April 12, 2000.
ADDRESSES: The service information referenced in this AD may be
obtained from Construcciones Aeronauticas, S.A., Getafe, Madrid, Spain.
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 all CASA Model CN-235-100 and CN-
235-200 series airplanes was published in the Federal Register on
January 5, 2000 (65 FR 399). That action proposed to require
replacement of existing anti-icing distributor valves with new,
improved valves.
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 2 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 30 work hours per
airplane to accomplish the required replacement, and that the average
labor rate is $60 per work hour. Required parts will cost approximately
$4,671 per airplane. Based on these figures, the cost impact of the AD
on U.S. operators is estimated to be $12,942, or $6,471 per airplane.
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 a substantial direct
effect 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, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
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

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 ice accumulation on the wings or tail of the
airplane, which could result in reduced controllability of the
airplane, accomplish the following:
Replacement
(a) Within 4 months after the effective date of this AD, replace
the existing anti-icing distributor valves, having part number (P/N)
AC960013, in the wing and tail areas of the airplane, with new,

Service Bulletin SB-235-30-14, dated August 13, 1999.
(b) As of the effective date of this AD, no person shall install
a distributor valve having P/N AC960013 on any airplane.
Alternative Methods of Compliance
(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

CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
Incorporation by Reference
(e) The replacement shall be done in accordance with CASA
Service Bulletin SB-235-30-14, dated August 13, 1999. This
incorporation by reference was approved by the Director of the
