RIN 2120-AA64
Airworthiness Directives; MORAVAN a.s. Models Z-143L and Z-242L
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) that
applies to certain MORAVAN a.s. (Moravan) Models Z-143L and Z-242L
airplanes. This AD requires you to modify the engine secondary vent
line. This AD is the result of mandatory continuing airworthiness
information (MCAI) issued by the airworthiness authority for the Czech
Republic. The actions specified by this AD are intended to prevent the
engine crankcase ventilation lines from freezing during flight in cold
weather (winter) conditions, which could result in oil leaking from the
engine. Such a condition could lead to engine failure.
DATES: This AD becomes effective on December 13, 2002.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the regulations as of
December 13, 2002.
ADDRESSES: You may get the service information referenced in this AD
from Moravan, Inc., 765 81 Otrokovice, Czech Republic; telephone: +420

SUPPLEMENTARY INFORMATION:
Discussion
What Events Have Caused This AD?
The Civil Aviation Authority (CAA), which is the airworthiness
authority for the Czech Republic, notified FAA that an unsafe condition
may exist on certain Moravan Models Z-143L and Z-242L airplanes. The
CAA reports that during a production delivery flight of a Model Z-242L
airplane, smoke accumulated in the cockpit of the airplane, and engine
oil pressure dropped significantly. As a result of this situation, the
pilot was forced to make an emergency landing.
Investigation analysis revealed that the engine crankcase
ventilation lines became frozen while flying in low ambient air
temperature (winter) conditions. When the engine crankcase ventilation
lines freeze, the front crankcase seal ring slips out, which allows oil
to leak from the engine.
What Is the Potential Impact if FAA Took No Action?
This condition, if not corrected, could result in the engine
crankcase ventilation lines freezing during flight in cold weather
(winter) conditions. Such a condition could lead to engine failure.
Has FAA Taken Any Action to This Point?
We issued a proposal to amend part 39 of the Federal Aviation
Regulations (14 CFR part 39) to include an AD that would apply to
certain Moravan Models Z-143L and Z-242L airplanes. This proposal was
published in the Federal Register as a notice of proposed rulemaking
(NPRM) on August 14, 2002 (67 FR 52899). The NPRM proposed to require
you to modify the engine secondary vent line.
Was the Public Invited To Comment?
The FAA encouraged interested persons to participate in the making
of this amendment. We did not receive any comments on the proposed rule
or on our determination of the cost to the public.
FAA's Determination
What Is FAA's Final Determination on This Issue?
After careful review of all available information related to the
subject presented above, we have determined that air safety and the
public interest require the adoption of the rule as proposed except for
minor editorial corrections. We have determined that these minor
corrections:
--Provide the intent that was proposed in the NPRM for correcting the
unsafe condition; and
--Do not add any additional burden upon the public than was already
proposed in the NPRM.
Cost Impact
How Many Airplanes Does This AD Impact?
We estimate that this AD affects 39 airplanes in the U.S. registry.
What Is the Cost Impact of This AD on Owners/Operators of the Affected
Airplanes?
We estimate the following costs to accomplish the modification:
----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on U.S.
Labor cost Parts cost airplane operators
----------------------------------------------------------------------------------------------------------------
1 workhour x $60 per hour = $60........ No parts required......... $60 $60 x 39 = $2,340.
----------------------------------------------------------------------------------------------------------------

Regulatory Impact
Does This AD Impact Various Entities?
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.
Does This AD Involve a Significant Rule or Regulatory Action?
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 copy of the final evaluation prepared for this
action is contained in the Rules Docket. A copy of it may be obtained
by contacting the Rules Docket at the location provided under the
caption ADDRESSES.
