14 CFR Part 39
[Docket No. 98-NM-84-AD; Amendment 39-10911; AD 98-24-25]
RIN 2120-AA64
Airworthiness Directives; Lockheed Model L-188A and L-188C Series
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to all Lockheed Model L-188A and L-188C series airplanes,
that requires revising the Airplane Flight Manual to provide the
flightcrew with modified procedures and limitations for operating in
icing conditions. This amendment is prompted by incidents and accidents
involving airplanes equipped with turboprop engines that experienced
tailplane stall due to ice accretion on the horizontal stabilizer of
the airplane. The actions specified by this AD are intended to prevent
undetected accretion of ice on the horizontal stabilizer, which could
result in ice contaminated tailplane stall and consequent loss of pitch
control.
DATES: Effective December 30, 1998.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of December 30, 1998.
ADDRESSES: The service information referenced in this AD may be
obtained from Lockheed Aeronautical Systems Support Company (LASSC),
Field Support Department, Dept. 693, Zone 0755, 2251 Lake Park Drive,
Smyrna, Georgia 30080. 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 FAA, Small
Airplane Directorate, Atlanta Aircraft Certification Office, One Crown
Center, 1895 Phoenix Boulevard, suite 450, Atlanta, Georgia; or at the
Office of the Federal Register, 800 North Capitol Street, NW., suite
700, Washington, DC.

Directorate, Atlanta Aircraft Certification Office, One Crown Center,

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 Lockheed Model L-188A and L-
188C series airplanes was published in the Federal Register on August
13, 1998 (63 FR 43340). That action proposed to require revising the
Airplane Flight Manual to provide the flightcrew with modified
procedures and limitations for operating in icing conditions.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the single comment received.
The commenter supports the proposed rule.
Conclusion
After careful review of the available data, including the comment
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule as proposed.
Cost Impact
There are approximately 75 airplanes of the affected design in the
worldwide fleet. The FAA estimates that 32 airplanes of U.S. registry
will be affected by this AD, that it will take approximately 1 work
hour per airplane to accomplish the required incorporation of the AFM
revisions, and that the average labor rate is $60 per work hour. Based
on these figures, the cost impact of the AD on U.S. operators is
estimated to be $1,920, or $60 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 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
ADDRESSES.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
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:
98-24-25 Lockheed: Amendment 39-10911. Docket 98-NM-84-AD.
Applicability: All Model L-188A and L-188C series airplanes,
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 (b) 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 undetected accretion of ice on the horizontal
stabilizer, which could result in ice contaminated tailplane stall
and consequent loss of pitch control, accomplish the following:
[[Page 65046]]
(a) Within 30 days after the effective date of this AD, revise
the Limitations, Normal Procedures, and Performance Sections and
Appendix III of the FAA-approved Electra 188A or 188C Airplane
Flight Manual (AFM), as applicable, to include the pages specified
in Table 1 (for Model L-188A series airplanes), Table 2 (for Model
L-188C series airplanes not equipped with Hamilton Standard
propellers), or Table 3 (for Model L-188C series airplanes equipped
with Hamilton Standard propellers) of this AD, as applicable.
