ACTION:
 
Final rule.


––––––––––––––––––––––––––––––––––


SUMMARY:
 
We are revising an existing airworthiness directive (AD) for all GA200 (Pty) Ltd


Models GA200 and GA200C airplanes. 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 failure of the


wing strut bolt through the main spar. We are issuing this AD to require actions to address the unsafe


condition on these products.


DATES:
 
This AD is effective January 31, 2013.


The Director of the Federal Register approved the incorporation by reference of a certain


publication listed in the AD as of January 31, 2013.

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


October 15, 2012 (77 FR 62466), and proposed to revise AD 2012-18-10, Amendment 39-17187 (77


FR 55686, September 11, 2012).


Since we issued AD 2012-18-10, Amendment 39-17187 (77 FR 55686, September 11, 2012), the


Civil Aviation Safety Authority (CASA), which is the aviation authority for the Commonwealth of


Australia, has issued AD AD/GA200/1, Amendment 1, dated September 21, 2012 (referred to after


this as ''the MCAI''), to correct an unsafe condition for the specified products.


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


that:


As a result of a reported case of failure of a strut on a GA200C aircraft, GippsAero has


issued a mandatory service bulletin to alert operators and maintenance organisations


and to provide inspection and rectification actions.


This Airworthiness Directive makes this inspection and rectification action mandatory.


Failure to complete the actions required by this service bulletin may result in wing


strut bolt failure, resulting in wing structural failure.


Amendment 1 is issued to revise the repeat inspection compliance time to 500 hours


(previously 100 hours). The requirement service bulletin is also revised to provide a


corrective action if the inboard (upper) strut fitting hole is found to be larger than


specified. The initial inspection compliance time of 10 hours remains unchanged.


This AD retains the actions required in AD 2012-18-10, Amendment 39-17187 (77 FR 55686,


September 11, 2012), changes the compliance time for the repetitive inspections from intervals of


100 hours time-in-service (TIS) to intervals of 500 hours TIS, and incorporates the revised service


bulletin that includes repair instructions in lieu of contacting the manufacturer. You may obtain


further information by examining the MCAI in the AD docket.


Comments


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


comments on the NPRM (77 FR 62466, October 15, 2012) or on the determination of the cost to the


public.


Conclusion


We reviewed the relevant data and determined that air safety and the public interest require


adopting the AD as proposed except for minor editorial changes. We have determined that these


minor changes:


•
 
Are consistent with the intent that was proposed in the NPRM (77 FR 62466, October 15,


2012) for correcting the unsafe condition; and
