Airworthiness Directives; GA 8 Airvan (Pty) Ltd Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2010-18-06, which applies to all GA8 Airvan (Pty) Ltd Model GA8 and 
GA8-TC320 airplanes. AD 2010-18-06 requires inspections and a minor 
design change to the forward slide of the cargo door with corrective 
action as necessary. Since the FAA issued AD 2010-18-06, the Civil 
Aviation Safety Authority (CASA), which is the aviation authority for 
Australia, superseded the previous CASA Australia AD to incorporate 
more detailed inspections and additional modifications as specified in 
updated service information published by the manufacturer. This 
proposed AD was prompted by reports of in-flight cargo door separation. 
This proposed AD would require inspections and rework (modifications) 
of the cargo door with corrective action as necessary. The FAA is 
proposing this AD to address the unsafe condition on these products.

DATES: The FAA must receive comments on this NPRM by March 8, 2024.

ADDRESSES: You may send comments, using the procedures found in 14 CFR

agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to Doug 
Rudolph, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, 
Westbury, NY 11590. Any commentary that the FAA receives which is not 
specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Background

    The FAA issued AD 2010-18-06, Amendment 39-16419 (75 FR 52253, 
August 25, 2010) (AD 2010-18-06), for all GA8 Airvan (Pty) Ltd Model 
GA8 and GA8-TC320 airplanes. AD 2010-18-06 was prompted by MCAI 
originated by CASA, which is the aviation authority for Australia. CASA 
Australia issued CASA Australia AD AD/GA8/3 Amdt 2, dated August 11, 
2010 (CASA Australia AD/GA8/3 Amdt 2) to correct an unsafe condition 
identified as excessive wear in the forward cargo door slide, which 
could result in an in-flight separation of the cargo door, with 
possible loss of control of the airplane. CASA Australia AD AD/GA8/3 
Amdt 2 was issued to require the actions in service information updated 
by the manufacturer to remove any ambiguities in the previous revision 
and provide an improved inspection method and a minor design change to 
the forward slide of the cargo door (inclusion of a slide backing 
plate, castellated nut, and split pin).
    AD 2010-18-06 requires doing all of Action 1 (measuring the groove 
width of

[[Page 4212]]

the forward cargo door slide and if it exceeds 0.145 inch at any point 
along the slide, or is cracked, installing a new slider assembly) and 
Action 2 (inspecting wear of the forward slide of the cargo door and 
doing applicable corrective action steps specified in Action 1) of 
GippsAero Pty. Ltd. Mandatory Service Bulletin SB-GA8-2005-23, Issue 3, 
dated August 5, 2010. The FAA issued AD 2010-18-06 to address excessive 
wear in the forward cargo door slide.

Actions Since AD 2010-18-06 Was Issued

    Since the FAA issued AD 2010-18-06, CASA Australia superseded CASA 
Australia AD AD/GA8/3 Amdt 2 and issued CASA Australia AD AD/GA8/3 Amdt 
3, dated August 18, 2023 (CASA Australia AD AD/GA8/3 Amdt 3) (also 
referred to as the MCAI). The MCAI states that inspections revealed 
cases of excessive wear in the forward slide of the cargo door. 
Excessive wear in the forward slide of the cargo door may result in the 
cargo door separating from the airplane in flight with potentially 
catastrophic results. The MCAI requires accomplishing the actions 
specified in GippsAero Service Bulletin SB-GA8-2005-23, Issue 7, dated 
May 30, 2023 (GippsAero Service Bulletin SB-GA8-2005-23, Issue 7). This 
service bulletin includes procedures for revised inspections of the 
door mechanism, installing a stop on the forward slide of the cargo 
door and reworking the door slide to suit (accommodate) the track stop 
installation. Depending on the findings of the inspections, additional 
actions might be necessary including reworking the door mechanism 
pivot, upgrading the door operating rod, or fitting a door handle with 
an integral stop.
    The FAA is proposing this AD to address excessive wear in the 
forward slide of the cargo door. The unsafe condition, if not 
addressed, could result in the cargo door separating from the airplane 
during flight, with potential loss of control of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-0035.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed GippsAero Service Bulletin SB-GA8-2005-23, Issue 
8, dated October 11, 2023 (GippsAero SB-GA8-2005-23, Issue 8). This 
service information specifies procedures for installing a backing plate 
on the forward slide of the cargo door; inspecting the forward slide of 
the cargo door for excessive wear; inspecting the cargo door latching 
mechanism for contact between the operating rod and door handle pivot 
post, inspecting the threaded studs and rod ends at both ends of the 
operating rod for bending, and checking the cargo door handle 
engagement with the catch; reworking the cargo door handle pivot post; 
reworking the door operating rod; inspecting the door handle to 
determine if an integrated stop is installed and checking for excessive 
play; and inspecting the center rail of the cargo door to determine if 
an aft stop is installed, installing an aft stop, and reworking the 
center rail of the cargo door to accommodate the track stop.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in ADDRESSES.

FAA's Determination

    These products have been approved by the aviation authority of 
another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with this State of Design 
Authority, it has notified the FAA of the unsafe condition described in 
the MCAI and service information referenced above. The FAA is issuing 
this NPRM after determining that the unsafe condition described 
previously is likely to exist or develop on other products of the same 
type design.

Proposed AD Requirements in This NPRM

    This proposed AD would retain none of the requirements of AD 2010-
18-06. This proposed AD would require accomplishing the actions 
specified in the service information already described, except as 
discussed under ``Differences Between this Proposed AD and the MCAI.''

Differences Between This Proposed AD and the MCAI

    The MCAI applicability is Gippsland Aeronautics Model GA8 Series 
airplanes, all serial numbers. The applicability in this proposed AD 
would be GA8 Airvan (Pty) Ltd Model GA8 and GA8-TC320 airplanes because 
the FAA type certificate specifies GA8 Airvan (Pty) Ltd instead of 
Gippsland Aeronautics and specifies Model GA8 and GA8-TC320 airplanes 
instead of Model GA8 Series airplanes.
    The MCAI requires doing the actions in Gippsland Aeronautics 
mandatory service bulletin SB-GA8-2005-23 Issue 7, dated May 30, 2023. 
This proposed AD would require doing the actions in GippsAero SB-GA8-
2005-23, Issue 8. After the MCAI was published, the manufacturer issued 
GippsAero SB-GA8-2005-23, Issue 8, which was revised to provide 
clarification regarding the actions and compliance schedule. The title 
page of GippsAero SB-GA8-2005-23, Issue 8, specifies GippsAero instead 
of Gippsland Aeronautics.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 61 airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this proposed 
AD. The corresponding letter and number in parenthesis refer to the 
specific paragraph in GippsAero SB-GA8-2005-23, Issue 8.

    The FAA estimates the following costs to do any necessary actions 
that would be required based on the results of the proposed 
inspections. The agency has no way of determining the number of 
airplanes that might need these actions. The corresponding letter and 
number in parenthesis refer to the specific paragraph in GippsAero SB-
GA8-2005-23, Issue 8.

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected operators.

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.
    The FAA is 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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD 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.
    For the reasons discussed above, I certify that the proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
