[Docket No. FAA-2010-0463; Directorate Identifier 2010-CE-021-AD; Amendment 39-16425;


AD 2010-10-01 R1]

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


AGENCY:
 
Federal Aviation Administration (FAA), Department of Transportation (DOT).


ACTION:
 
Final rule.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
We are revising an existing airworthiness directive (AD) for the products listed above.


This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation


authority of another country to identify and correct an unsafe condition on an aviation product. The


MCAI describes the unsafe condition as:


Inspection of a high time aircraft has revealed cracks in the Horizontal Stabiliser rear


spar splice plate and inboard main ribs around the area of the Horizontal Stabiliser rear


pivot attachment. Additionally, failure of some attach bolts in service may be due to


improper assembly.


This amendment is issued to include an applicability matrix (Table 1, page 2) in the


compliance section of the service bulletin for improved clarity.


We are issuing this AD to require actions to correct the unsafe condition on these products.


DATES:
 
This AD becomes effective October 7, 2010.


On October 7, 2010, the Director of the Federal Register approved the incorporation by reference


of Gippsland Aeronautics Mandatory Service Bulletin SB-GA8-2002-02, Issue 6, dated April 21,


2010, listed in this AD.


As of March 2, 2009 (74 FR 8159; February 24, 2009), the Director of the Federal Register


approved the incorporation by reference of Gippsland Aeronautics Mandatory Service Bulletin SB-


GA8-2002-02, Issue 5, dated November 13, 2008, listed in this AD.

SUPPLEMENTARY INFORMATION:


Discussion


We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD


that would apply to the specified products. That NPRM was published in the Federal Register on June


21, 2010 (75 FR 34953), and proposed to revise AD 2010-10-01, Amendment 39-16280 (75 FR


23577, May 4, 2010).


Since we issued AD 2010-10-01, the foreign authority has issued an amendment to include an


applicability matrix in the compliance section of the manufacturer's service bulletin for improved


clarity. The FAA is revising this AD to allow the use of issue 6 or issue 5 of the service bulletin. An


operator would be in compliance if the operator chose to only accomplish issue 5 of the service


bulletin. This revision of the FAA's AD will make the FAA AD more in line with the latest version of


the received MCAI.


The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states


that:


Inspection of a high time aircraft has revealed cracks in the Horizontal Stabiliser rear


spar splice plate and inboard main ribs around the area of the Horizontal Stabiliser rear


pivot attachment. Additionally, failure of some attach bolts in service may be due to


improper assembly.


This amendment is issued to include an applicability matrix (Table 1, page 2) in the


compliance section of the service bulletin for improved clarity.


The previous amendment included reference to the GA8-TC 320 variant in the


applicability section.


Amendment 2 was issued because the requirement document now contains an


inspection for cracking in horizontal stabilisers which have load transferring fittings


installed.


Previous amendments of this AD listed the AD requirements in full. Due to the


extensive use of diagrams and photographs, it is no longer appropriate or practical to


write the requirements of the service bulletin out in full in this AD. All requirements,


accomplishment instructions and illustrations are contained in the service bulletin.


Comments


We gave the public the opportunity to participate in developing this AD. We received no


comments on the NPRM or on the determination of the cost to the public.
