[Docket No. 2000-CE-35-AD; Amendment 39-12869; AD 2002-17-04]
RIN 2120-AA64


Airworthiness Directives; Ballonbau Worner GmbH Model K-630/1-Stu 
Manned Free Gas Balloons

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to all Ballonbau Worner GmbH (Ballonbau) Model K-630/1-Stu 
manned free gas balloons. This AD requires you to replace the PVC tubes 
that cover the steelwire loops of the basket with an electrostatic 
conductive braided rope. This AD is the result of mandatory continuing 
airworthiness information (MCAI) issued by the airworthiness authority 
for Germany. The actions specified by this AD are intended to prevent 
the chance of an electrostatic charge buildup between the steelwire 
loops of the basket and the balloon envelope, which could result in 
ignition of combustible lifting gas fumes in the balloon envelope. Such 
a condition could lead to gas explosion and fire.

DATES: This AD becomes effective on September 30, 2002.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulation as of 
September 30, 2002.
    The Federal Aviation Administration (FAA) must receive any comments 
on this rule on or before October 10, 2002.

ADDRESSES: Submit comments to FAA, Central Region, Office of the 
Regional Counsel, Attention: Rules Docket No. 2000-CE-35-AD, 901

SUPPLEMENTARY INFORMATION:

Discussion

What Events Have Caused This AD?

    The Luftfahrt-Bundesamt (LBA), which is the airworthiness authority 
for Germany, notified FAA that an unsafe condition may exist on all 
Ballonbau Model K-630/1-Stu manned free gas balloons. The LBA reports 
the potential of an electrostatic build up between the steelwire loops 
of the basket and the balloon envelope.
    Ballonbau has designed an electrostatic conductive braided rope to 
address this condition.

What Are the Consequences if the Condition Is Not Corrected?

    This condition, if not prevented, could result in ignition of 
combustible lifting gas fumes in the balloon envelope. Such a condition 
could lead to gas explosion and fire.

Is There Service Information That Applies to This Subject?

    Ballonbau has issued Technical Note Nr. 8002-13, dated January 14, 
2000.
    This service information includes procedures for removing the PVC 
tubes that cover the steelwire loops of the basket and installing an 
electrostatic conductive braided rope.

What Action Did the LBA Take?

    The LBA classified this service bulletin as mandatory and issued 
German AD Number 2000-063, dated February 24, 2000, in order to ensure 
the continued airworthiness of these balloons in Germany.

Was This in Accordance With the Bilateral Airworthiness Agreement?

    This balloon model is manufactured in Germany and is 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 us informed of the situation described above.

The FAA's Determination and an Explanation of the Provisions of This 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 
develop on other Ballonbau Model K-630/1-Stu manned free gas balloons 
of the same type design;
--The actions specified in the previously-referenced service 
information (as specified in this AD) should be accomplished on the 
affected balloons; and
--AD action should be taken in order to correct this unsafe condition.

What Does This AD Require?

    This AD requires you to incorporate the actions in the previously-
referenced service bulletin.

Will I Have the Opportunity To Comment Prior to the Issuance of the 
Rule?

    Since this AD action does not affect any balloon that is currently 
on the U.S. register, it has no adverse economic impact and imposes no 
additional burden on any person. Therefore, notice and opportunity for 
public prior

[[Page 55715]]

comment are unnecessary and the amendment may be made effective in less 
than 30 days after publication in the Federal Register.
    None of the Ballonbau Model K-630/1-Stu manned free gas balloons 
affected by this action are on the U.S. Register. All balloons included 
in the applicability of this rule currently are operated by non-U.S. 
operators under foreign registry; therefore, they are not directly 
affected by this AD action. However, the FAA considers this rule 
necessary to ensure that the unsafe condition is addressed in the event 
that any of these subject balloons are imported and placed on the U.S. 
Register.

Comments Invited

How Do I Comment on This AD?

    Although this action is in the form of a final rule and was not 
preceded by notice and opportunity for public comment, FAA invites your 
comments on the rule. You may submit whatever written data, views, or 
arguments you choose. You need to include the rule's docket number and 
submit your comments to the address specified under the caption 
ADDRESSES. We will consider all comments received on or before the 
closing date specified above. We may amend this rule in light of 
comments received. Factual information that supports your ideas and 
suggestions is extremely helpful in evaluating the effectiveness of 
this AD action and determining whether we need to take additional 
rulemaking action.

Are There Any Specific Portions of This AD I Should Pay Attention to?

    We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the 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 FAA contact 
with the public that concerns the substantive parts of this AD.

How Can I Be Sure FAA Receives My Comment?

    If you want us to acknowledge the receipt of your comments, you 
must include a self-addressed, stamped postcard. On the postcard, write 
``Comments to Docket No. 2000-CE-35-AD.'' We will date stamp and mail 
the postcard back to you.

Compliance Time of this AD

What Is the Compliance Time of This AD?

    The compliance time of this AD is within the next 30 days after the 
effective date of this AD.

Why Is the Compliance Time Presented in Calendar Time Instead of Hours 
Time-In-Service (TIS)?

    This unsafe condition is not a result of the number of times the 
balloon is operated. The chance of this situation occurring is the same 
for a balloon with 10 hours time-in-service (TIS) as it would be for a 
balloon with 500 hours TIS. For this reason, the FAA has determined 
that a compliance based on calendar time should be utilized in this AD 
in order to assure that the unsafe condition is addressed on all 
balloons in a reasonable time period.

Regulatory Impact

Does This AD Impact Various Entities?

    These regulations 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, FAA has determined that this 
final rule does not have federalism implications under Executive Order 
13132.

Does This AD Involve a Significant Rule or Regulatory Action?

    We have determined that this regulation is an emergency regulation 
that must be issued immediately to correct an unsafe condition in 
aircraft, and is not a significant regulatory action under Executive 
Order 12866. It has been determined further that this action involves 
an emergency regulation under DOT Regulatory Policies and Procedures 
(44 FR 11034, February 26, 1979). If it is determined that this 
emergency regulation otherwise would be significant under DOT 
Regulatory Policies and Procedures, a final regulatory evaluation will 
be prepared and placed in the Rules Docket (otherwise, an evaluation is 
not required). A copy of it, if filed, may be obtained from the Rules 
Docket.
