Airworthiness Directives; GA 8 Airvan (Pty) Ltd Models GA8 and 
GA8-TC320 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above that will supersede an existing AD. This AD 
results from mandatory continuing airworthiness information (MCAI) 
issued by the aviation authority of another country to identify and 
correct an unsafe condition on an aviation product. The MCAI describes 
the unsafe condition as:

    Inspections have revealed cases of excessive wear in the forward 
slide of the cargo door. Excessive wear in the door slide may result 
in the door becoming detached from the aircraft in flight, with 
potentially catastrophic results.

This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

DATES: This AD becomes effective August 30, 2010.
    On August 30, 2010, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in this 
AD.
    We must receive comments on this AD by October 12, 2010.

SUPPLEMENTARY INFORMATION: 

Discussion

    On October 18, 2005, we issued AD 2005-22-02, Amendment 39-14346 
(70 FR 61547; October 25, 2005). That AD required actions intended to 
address an unsafe condition on the products listed above.
    Since we issued AD 2005-22-02, there has been another report of an 
in-flight cargo door separation. Consequently, GA 8 Airvan (Pty) Ltd 
has revised the service information by improving the inspection method 
and making a minor design change to the door slide.
    The Civil Aviation Safety Authority (CASA), which is the aviation 
authority for Australia, has issued AD/GA8/3, Amdt 2, dated August 11, 
2010 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    Inspections have revealed cases of excessive wear in the forward 
slide of the cargo door. Excessive wear in the door slide may result 
in the door becoming detached from the aircraft in flight, with 
potentially catastrophic results.
    Following a recent in-flight door separation, this amendment is 
issued to update the service bulletin to remove any ambiguities that 
could have existed in the previous revision to the referenced 
service bulletin. It also provides an improved inspection method and 
a minor design change to the cargo door slide (inclusion of slide 
backing plate, castellated nut and spilt [sic] pin).

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    GippsAero Pty. Ltd. has issued Mandatory Service Bulletin SB-GA8-
2005-23, Issue 3, dated August 5, 2010. The actions described in this 
service information are intended to correct the unsafe condition 
identified in the MCAI.

FAA's Determination and Requirements of the AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are issuing this AD because we 
evaluated all information provided by the State of Design Authority and 
determined the unsafe condition exists and is likely to exist or 
develop on other products of the same type design.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might have also required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
described in a separate paragraph of the AD. These requirements take 
precedence over those copied from the MCAI.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because an 
in-flight separation of the door could potentially strike the 
horizontal stabilizer structure, which could lead to failure of the 
tailplane assembly. Therefore, we determined that notice and 
opportunity for public comment before issuing this AD are impracticable 
and that good cause exists for making this amendment effective in fewer 
than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and

[[Page 52254]]

we did not precede it by notice and opportunity for public comment. We 
invite you to send any written relevant data, views, or arguments about 
this AD. Send your comments to an address listed under the ADDRESSES 
section. Include ``Docket No. FAA-2010-0847; Directorate Identifier 
2010-CE-046-AD'' at the beginning of your comments. We specifically 
invite comments on the overall regulatory, economic, environmental, and 
energy aspects of this AD. We will consider all comments received by 
the closing date and may amend this AD because of those comments.
    We will post all comments we receive, without change, to http://
www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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 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.

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 FAA amends Sec.  39.13 by removing Amendment 39-14346 (70 FR 
61547; October 25, 2005), and adding the following new AD:

2010-18-06 GA 8 AIRVAN (PTY) LTD: Amendment 39-16419; Docket No. 
FAA-2010-0847; Directorate Identifier 2010-CE-046-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective August 
30, 2010.

Affected ADs

    (b) This AD supersedes AD 2005-22-02, Amendment 39-14346.

Applicability

    (c) This AD applies to GA 8 Airvan (Pty) Ltd Models GA8 and GA8-
TC320 airplanes, all serial numbers, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 52: Doors.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    Inspections have revealed cases of excessive wear in the forward 
slide of the cargo door. Excessive wear in the door slide may result 
in the door becoming detached from the aircraft in flight, with 
potentially catastrophic results.
    Following a recent in-flight door separation, this amendment is 
issued to update the service bulletin to remove any ambiguities that 
could have existed in the previous revision to the referenced 
service bulletin. It also provides an improved inspection method and 
a minor design change to the cargo door slide (inclusion of slide 
backing plate, castellated nut and spilt [sic] pin).

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within 500 hours total time-in-service (TIS) of the airplane 
or within the next 10 hours TIS after August 30, 2010 (the effective 
date of this AD), whichever occurs later, do all of Action 1: of 
GippsAero Pty. Ltd. Mandatory Service Bulletin SB-GA8-2005-23, Issue 
3, dated August 5, 2010.
    (2) Within 100 hours TIS after doing the actions in paragraph 
(f)(1) of this AD or within 12 calendar months after doing the 
actions in paragraph (f)(1) of this AD, whichever occurs first, and 
repetitively thereafter at intervals not to exceed 100 hours TIS or 
12 calendar months, whichever occurs first, do all of Action 2: of 
GippsAero Pty. Ltd. Mandatory Service Bulletin SB-GA8-2005-23, Issue 
3, dated August 5, 2010.
    (3) If a cracked or excessively worn slider is found during any 
inspection required in paragraph (f)(1) or (f)(2) of this AD, before 
further flight replace the slider.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows: The MCAI and service information only list the Model GA8 
in the applicability. The cargo door for the Model GA8-TC320 has the 
same design and this AD also applies to the Model GA8-TC320.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Standards Office, FAA, has the authority to approve AMOCs for this 
AD, if requested using the procedures found in 14 CFR 39.19. Send 
information to ATTN: Doug Rudolph, Aerospace Engineer, FAA, Small 
Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 
64106; telephone: (816) 329-4059; fax: (816) 329-4090. Before using 
any approved AMOC on any airplane to which the AMOC applies, notify 
your appropriate principal inspector (PI) in the FAA Flight 
Standards District Office (FSDO), or lacking a PI, your local FSDO.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, under the provisions of the Paperwork Reduction Act (44 
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has 
approved the information collection requirements and has assigned 
OMB Control Number 2120-0056.
