14 CFR Part 39
[Docket No. 2003-CE-20-AD]
RIN 2120-AA64
Airworthiness Directives; Dornier Luftfahrt GMBH Models 228-100,
228-101, 228-200, 228-201, 228-202, and 228-212 Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: This document proposes to adopt a new airworthiness directive
(AD) that would apply to certain Dornier Luftfahrt GMBH (Dornier)
Models 228-100, 228-101, 228-200, 228-201, 228-202, and 228-212
airplanes that have electrical cabin/cockpit heater option P05 or
option P09 installed. This proposed AD would require you to modify the
cockpit and cabin auxiliary heating wiring. This proposed AD is the
result of mandatory continuing airworthiness information (MCAI) issued
by the airworthiness authority for Germany. The actions specified by
this proposed AD are intended to correct problems with the current
design of the heater wiring, which could result in failure of the
auxiliary cabin heater. Such failure could lead to overheating and
smoke in the cockpit.
DATES: The Federal Aviation Administration (FAA) must receive any
comments on this proposed rule on or before June 23, 2003.
ADDRESSES: Submit comments to FAA, Central Region, Office of the
Regional Counsel, Attention: Rules Docket No. 2003-CE-20-AD, 901
Locust, Room 506, Kansas City, Missouri 64106. You may view any
comments at this location between 8 a.m. and 4 p.m., Monday through
Friday, except Federal holidays. You may also send comments
electronically to the following address: 9-ACE-7-Docket@faa.gov.
Comments sent electronically must contain ``Docket No. 2003-CE-20-AD''
in the subject line. If you send comments electronically as attached

AD action and determining whether we need to take additional rulemaking
action.
Are there any specific portions of this proposed AD I should pay
attention to? The FAA specifically invites comments on the overall
regulatory, economic, environmental, and energy aspects of this
proposed rule that might suggest a need to modify the rule. You may
view all comments we receive before and after the closing date of the
rule in the Rules Docket. We will file a report in the Rules Docket
that summarizes each contact we have with the public that concerns the
substantive parts of this proposed AD.

Docket No. 2003-CE-20-AD.'' We will date stamp and mail the postcard
back to you.
Discussion
What events have caused this proposed AD? The Luftfahrt-Bundesamt
(LBA), which is the airworthiness authority for Germany, recently
notified FAA that an unsafe condition may exist on certain Dornier
Models 228-100, 228-101, 228-200 and 228-201, 228-202, and 228-212
airplanes. The LBA reports an occurrence of stuck contacts of the power
relay of the heating circuit to the auxiliary cabin heater, Dornier
option P05 or P09.
What are the consequences if the condition is not corrected?
Failure of the auxiliary cabin heater could lead to overheating and
smoke in the cockpit.
Is there service information that applies to this subject? Dornier
has issued Service Bulletin No. 228-249, Revision No. 1, dated November
19, 2001.
What are the provisions of this service information? The service
bulletin includes procedures for modifying the auxiliary cabin heater
wiring.
What action did the LBA take? The LBA classified this service
bulletin as mandatory and issued German AD Number 2002-264, dated
September 19, 2002, in order to ensure the continued airworthiness of
these airplanes in Germany.
Was this in accordance with the bilateral airworthiness agreement?
These airplane models are manufactured in Germany and are type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement.
Pursuant to this bilateral airworthiness agreement, the LBA has
kept FAA informed of the situation described above.
The FAA's Determination and an Explanation of the Provisions of This
Proposed AD
What has FAA decided? The FAA has examined the findings of the LBA;
reviewed all available information, including the service information
referenced above; and determined that:
--The unsafe condition referenced in this document exists or could
devlop on other Dornier Models 228-100, 228-101, 228-200 and 228-201,
228-202, and 228-212 airplanes of the same type design that are on the
U.S. registry;
--The actions specified in the previously-referenced service
information should be accomplished on the affected airplanes; and
--AD action should be taken in order to correct this unsafe condition.
What would this proposed AD require? This proposed AD would require
you to incorporate the actions in the previously-referenced service
bulletin.
How does the revision to 14 CFR part 39 affect this proposed AD? On
July 10, 2002, FAA published a new version of 14 CFR part 39 (67 FR
47997, July 22, 2002), which governs FAA's AD system. This regulation
now includes material that relates to special flight permits,
alternative methods of compliance, and altered products. This material
previously was included in each individual AD. Since this material is
included in 14 CFR part 39, we will not include it in future AD
actions.
Cost Impact
How many airplanes would this proposed AD impact? We estimate that
this proposed AD affects 14 airplanes in the U.S. registry.
What would be the cost impact of this proposed AD on owners/
operators of the affected airplanes? We estimate the following costs to
accomplish this proposed modification. We have no way of determining
the number of airplanes that may need such modification:
------------------------------------------------------------------------
Total cost
Labor cost Parts cost per airplane
------------------------------------------------------------------------
3 workhours x $60 per hour = $180........... $95. $275.
------------------------------------------------------------------------
Regulatory Impact
Would this proposed AD impact various entities? The regulations
proposed herein would 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
proposed rule would not have federalism implications under Executive
Order 13132.
Would this proposed AD involve a significant rule or regulatory
action? For the reasons discussed above, I certify that this proposed
action (1) is not a ``significant regulatory action'' under Executive
Order 12866; (2) is not a ``significant rule'' under DOT
[[Page 26244]]
Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
and (3) if promulgated, 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 draft
regulatory evaluation prepared for this action has been placed in the
Rules Docket. A copy of it may be obtained by contacting the Rules
Docket at the location provided under the caption ADDRESSES.
