14 CFR Part 39
[Docket No. FAA-2005-22401; Directorate Identifier 2004-NM-93-AD;
Amendment 39-14480; AD 2006-03-16]
RIN 2120-AA64
Airworthiness Directives; Hamburger Flugzeugbau GmbH Model HFB
320 HANSA Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Hamburger Flugzeugbau GmbH Model HFB 320 HANSA airplanes. This AD
requires revising the Limitations section of the HFB 320 Hansa Airplane
Flight Manual to prohibit operation of the airplane past its designed
life limit for the primary structure, which is 15,000 flight hours or
15,000 fight cycles, whichever occurs first; and to require contacting
the FAA for approval of analysis that the airplane is safe to continue
operation beyond the designed life limit. This AD results from a report
that all airplanes in operation might have met or exceeded the designed
life limit for the primary structure. We are issuing this AD to prevent
continued operation of an airplane beyond its designed life limit for
the primary structure, which could result in reduced structural
integrity of the airplane.
DATES: This AD becomes effective March 15, 2006.
ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov
or in person at the Docket Management Facility, U.S.
Department of Transportation, 400 Seventh Street, SW., Nassif Building,
room PL-401, Washington, DC.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the airworthiness directive (AD) docket on the
Internet at http://dms.dot.gov or in person at the Docket Management
Facility office between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Management Facility office
(telephone (800) 647-5227) is located on the plaza level of the Nassif
Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to all Hamburger
Flugzeugbau GmbH Model HFB 320 HANSA airplanes. That NPRM was published
in the Federal Register on September 14, 2005 (70 FR 54314). That NPRM
proposed to require revising the Limitations section of the HFB 320
Hansa Airplane Flight Manual (AFM) to prohibit operation of the
airplane past its designed life limit for the primary structure, which
is 15,000 flight hours or 15,000 fight cycles, whichever occurs first;
and to require contacting the FAA for approval of analysis that the
airplane is safe to continue operation beyond the designed life limit.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received no comments on the NPRM or on the
determination of the cost to the public.
Clarification of Alternative Method of Compliance (AMOC) Paragraph
We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any approved AMOC on
any airplane to which the AMOC applies.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD with the
change described previously. We have determined that this change will
neither increase the economic burden on any operator nor increase the
scope of the AD.
Costs of Compliance
There are 4 airplanes of U.S. registry that will be affected by
this AD. The revision to the Limitations section will take about 1 work
hour per airplane at an average labor rate of $65 per work hour. Based
on these figures, the cost of the AFM revision for U.S. operators will
be $260, or $65 per airplane. We recognize that this AD may impose
certain additional operational costs. However, we cannot calculate
those costs because we cannot predict the extent of any necessary
repairs to ensure the continued airworthiness of the affected
airplanes.

Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
subtitle VII, part A, subpart III, section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD 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.
For the reasons discussed above, I certify that this AD:
(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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The Federal Aviation Administration (FAA) amends Sec. 39.13 by
adding the following new airworthiness directive (AD):
2006-03-16 Hamburger Flugzeugbau GmbH: Amendment 39-14480. Docket
No. FAA-2005-22401; Directorate Identifier 2004-NM-93-AD.
Effective Date
(a) This AD becomes effective March 15, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Hamburger Flugzeugbau GmbH Model HFB
320 HANSA airplanes, certificated in any category.
Unsafe Condition
(d) This AD results from a report that all airplanes in
operation might have met or exceeded the designed life limit for the
primary structure. We are issuing this AD to prevent continued
operation of an airplane beyond its designed life limit for the
primary structure, which could result in reduced structural
integrity of the airplane.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Airworthiness Limitations Revision
(f) Within 30 days after the effective date of this AD: Revise
the Limitations section of the HFB 320 Hansa Airplane Flight Manual
(AFM) to state the following (or insert a copy of this AD into the
Limitations section):
``Do not operate the airplane beyond 15,000 total flight cycles, or
15,000 total flight hours, whichever occurs first.''
(g) This limitation may be removed from the HFB 320 Hansa AFM
after the Manager, International Branch, ANM-116, FAA, approves
analysis that would substantiate continued safe operation beyond the
designed life limit of 15,000 total flight cycles, or within 15,000
total flight hours on the airplane, whichever occurs first.
Alternative Methods of Compliance (AMOCs)
(h)(1) The Manager, International Branch, ANM-116, has the
authority to approve AMOCs for this AD, if requested in accordance
with the procedures found in 14 CFR 39.19.
(2) Before using any AMOC approved in accordance with Sec.
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.

(i) German airworthiness directive 2002-158, effective October
3, 2002, also addresses the subject of this AD.
Material Incorporated by Reference
