The Civil Aviation Safety Authority (CASA), which is the aviation authority for Australia, has issued AD/GA8/6, dated August 6, 2012 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:
CASA has received a number of Service Difficulty Reports regarding the pitot probe heater connector. The loss of pitot heat in Instrument Meteorological Condition (IMC) may lead to the loss of airspeed indication. This may lead to the loss of control of the aeroplane. Remedial action is to replace the connector with a terminal block.
GippsAero has issued Mandatory Service Bulletin SB-GA8-2012-77, Issue 3, dated March 23, 2012. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.
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 proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
We estimate that this proposed AD will affect 29 products of U.S. registry. We also estimate that it would take about 4 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $100 per product.
Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $12,760, or $440 per product.
According to the manufacturer, all of the costs of this proposed AD may be covered under warranty, thereby
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.
We 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 this proposed regulation:
(1) Is not a “significant regulatory action” under Executive Order 12866,
(2) Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
1. The authority citation for part 39 continues to read as follows:
49 U.S.C. 106(g), 40113, 44701.
2. The FAA amends § 39.13 by adding the following new AD:
We must receive comments by November 5, 2012.
This AD applies to GA 8 Airvan (Pty) Ltd Models GA8 and GA8-TC320 airplanes, all serial numbers, certificated in any category.
Air Transport Association of America (ATA) Code 30, Ice and Rain Protection.
This AD was prompted by burnt electrical connectors leading to the left-hand wingtip pitot heater, which may result in loss of air speed indication. We are issuing this proposed AD to modify the pitot heat wiring on the left-hand wingtip with a terminal block to prevent loss of heating to the pitot system, which could result in loss of air speed indication.
Unless already done, within the next 100 hours time-in-service or at the next annual inspection, whichever occurs later, modify the pitot heat wiring connector at the left wingtip, following GippsAero Mandatory Service Bulletin SB-GA8-2012-77, Issue 3, dated March 23, 2012.
The following provisions also apply to this AD:
Refer to MCAI Civil Aviation Safety Authority AD/GA8/6, dated August 6, 2012; and GippsAero Mandatory Service Bulletin SB-GA8-2012-77, Issue 3, dated March 23, 2012, for related information.
