CFR Citation: 14 CFR Part 39

Docket ID: [Docket No. FAA-2008-0057 Directorate Identifier 2007-CE-102-AD; Amendment 39-15445; AD 2008-07-04]

RIN ID: RIN 2120-AA64

NOTICE: RULES

ACTION: Airworthiness Directives:

DOCUMENT ACTION: Final rule.

SUBJECT CATEGORY: Airworthiness Directives; APEX Aircraft Model CAP 10 B Airplanes

DATES: This AD becomes effective April 30, 2008.

On April 30, 2008, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

DOCUMENT SUMMARY: We are adopting a new 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:

A case of loose bond (ungluing) of one mounting wooden block of the control stick base cover, found during the cover reinstallation, was reported to the Type Certificate Holder (TCH) and led to the issuance of the ``recommended'' Service Bulletin (SB) No. 031004 in February 2004. Since that date, other similar occurrences have been reported. This SB in its revision 1, has therefore been reclassified ``mandatory'' by the TCH.

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

SUMMARY: APEX Aircraft Model CAP 10 B Airplanes,

SUPPLEMENTAL INFORMATION

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 January 24, 2008 (73 FR 4123). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

A case of loose bond (ungluing) of one mounting wooden block of the control stick base cover, found during the cover reinstallation, was reported to the Type Certificate Holder (TCH) and led to the issuance of the ``recommended'' Service Bulletin (SB) No.031004 in February 2004. Since that date, other similar occurrences have been reported. This SB in its revision 1, has therefore been reclassified ``mandatory'' by the TCH.

This Airworthiness Directive (AD) mandates inspection of the mounting blocks of the control stick base cover for loose bonds and repair, as necessary.

These actions are intended to address the identified unsafe condition so as to prevent separation of the mounting blocks from the wing spar which could result in restricted movement of the ailerons and elevators with possible partial or complete loss of controls.

The MCAI requires an inspection of the four mounting wooden blocks of the control stick base cover. You are to take corrective action by repairing any loose blocks where inspection indicates necessary. 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.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed.
Differences Between This AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

[[Page 15873]]

We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD.

Costs of Compliance

We estimate that this AD will affect 52 products of U.S. registry. We also estimate that it will take about .5 workhour per product to comply with basic requirements of this AD. The average labor rate is $80 per workhour. Required parts will cost about $135 per product.

Based on these figures, we estimate the cost of this AD to the U.S. operators to be $9,100 or $175 per product.

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 AD will not have federalism implications under Executive Order 13132. This AD will 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 AD: (1) Is not a ``significant regulatory action'' under Executive Order 12866;
(2) Is not a ``significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
(3) 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.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD Docket.

Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 6475527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

List of Subjects in 14 CFR Part 39

2. The FAA amends Sec. 39.13 by adding the following new AD: 20080704 APEX Aircraft: Amendment 3915445; Docket No. FAA2008 0057; Directorate Identifier 2007CE102AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective April 30, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to the following CAP 10 B airplanes that are certificated in any category:
(i) serial numbers 300 through 310; and
(ii) serial numbers 1 through 40 that have been retrofitted with carbon/wood wing reference 57020104048* (*with or without a variable letter or number at the reference end).
Subject
(d) Air Transport Association of America (ATA) Code 57: Wings. Reason
(e) The mandatory continuing airworthiness information (MCAI) states:

A case of loose bond (ungluing) of one mounting wooden block of the control stick base cover, found during the cover reinstallation, was reported to the Type Certificate Holder (TCH) and led to the issuance of the ``recommended'' Service Bulletin (SB) No. 031004 in February 2004. Since that date, other similar occurrences have been reported. This SB in its revision 1, has therefore been reclassified ``mandatory'' by the TCH.

This Airworthiness Directive (AD) mandates inspection of the mounting blocks of the control stick base cover for loose bonds and repair, as necessary.

These actions are intended to address the identified unsafe condition so as to prevent separation of the mounting blocks from the wing spar which could result in restricted movement of the ailerons and elevators with possible partial or complete loss of controls.

The MCAI requires an inspection of the four mounting wooden blocks of the control stick base cover. You are to take corrective action by repairing any loose blocks where inspection indicates necessary.
Actions and Compliance
(f) Unless already done, do the following actions within the next 6 months after April 30, 2008 (the effective date of this AD), following APEX Aircraft Service Bulletin No. 031004 R1, Revision 1, dated November 12, 2007:
(1) Inspect the four mounting wooden blocks of the control stick base cover for loose bonding (gluing); and
(2) If any wooden block is found to be loose, take corrective action.
