2012-25253. Airworthiness Directives; GA200 (Pty) Ltd Airplanes

AGENCY:

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

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for all GA200 (Pty) Ltd Models GA200 and GA200C airplanes that would revise an existing AD. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated 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 proposed AD to require actions to address the unsafe condition on these products.

DATES:

We must receive comments on this proposed AD by November 29, 2012.

Discussion

On August 31, 2012, we issued AD 2012-18-10, Amendment 39-17187 (77 FR 55686, September 11, 2012). That AD required actions intended to address an unsafe condition on the products listed above.

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 MCAI states:

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 proposed AD would retain the actions required in AD 2012-18-10, Amendment 39-17187 (77 FR 55686, September 11, 2012), change the compliance time for the repetitive inspections, and incorporate the revised service bulletin. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

GippsAero has issued Mandatory Service Bulletin SB-GA200-2012-08, Issue 2, dated September 4, 2012. 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 Proposed 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 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.

Costs of Compliance

We estimate that this proposed AD will affect 3 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $510, or $170 per product.

In addition, we estimate that any necessary follow-on actions would take about 2 work-hours and require parts costing $400, for a cost of $570 per product. We have no way of determining the number of products that may need these actions.

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 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.

List of Subjects in 14 CFR Part 39

• Air transportation
• Aircraft
• Aviation safety
• Incorporation by reference
• Safety

The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39—AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

§ 39.13

[Amended]

2. The FAA amends § 39.13 by removing Amendment 39-17187 (77 FR 55686, September 11, 2012), and adding the following new AD:

GA200 (Pty) Ltd: Docket No. FAA-2012-0946; Directorate Identifier 2012-CE-037-AD.

(a) Comments Due Date

We must receive comments by November 29, 2012.

(b) Affected ADs

This AD revises AD 2012-18-10, Amendment 39-17187 (77 FR 55686, September 11, 2012).

(c) Applicability

This AD applies to GA200 (Pty) Ltd Models GA200 and GA200C airplanes, all serial numbers, certificated in any category.

(d) Subject

Air Transport Association of America (ATA) Code 57: Wings.

(e) Reason

This AD was prompted by 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 failure of the wing strut bolt through the main spar. We are issuing this AD to prevent failure of the wing strut bolt, which could result in wing failure.

(f) Actions and Compliance

Unless already done, do the following actions.

(1) Within 10 hours time-in-service (TIS) after September 14, 2012 (the effective date retained from AD 2012-18-10, Amendment 39-17187 (77 FR 55686, September 11, 2012)), inspect the inboard strut fitting following GippsAero Mandatory Service Bulletin SB-GA200-2012-08, Issue 1, dated August 22, 2012; or GippsAero Mandatory Service Bulletin SB-GA200-2012-08, Issue 2, dated September 4, 2012. Repetitively thereafter inspect at intervals not to exceed 500 hours TIS following GippsAero Mandatory Service Bulletin SB-GA200-2012-08, Issue 2, dated September 4, 2012.

(2) If the 100-hour TIS repetitive inspection previously required in AD 2012-18-10, Amendment 39-17187 (77 FR 55686, September 11, 2012) has already been done before the effective date of this AD following GippsAero Mandatory Service Bulletin SB-GA200-2012-08, Issue 1, dated August 22, 2012, the next required inspections are due at intervals not to exceed 500 hours TIS after the last inspection following GippsAero Mandatory Service Bulletin SB-GA200-2012-08, Issue 2, dated September 4, 2012.

(3) If any discrepancies are found during any of the inspections required by paragraphs (f)(1) and (f)(2) of this AD, before further flight after the inspection in which the discrepancy is found, take all necessary corrective actions following GippsAero Mandatory Service Bulletin SB-GA200-2012-08, Issue 1, dated August 22, 2012; or GippsAero Mandatory Service Bulletin SB-GA200-2012-08, Issue 2, dated September 4, 2012.

(g) Other FAA AD Provisions

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: [phone]; fax: [phone]; email: [e-mail].
