AD 2006-06-07

The FAA is adopting a new airworthiness directive (AD) for certain Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires inspecting the main landing gear (MLG) main fitting for cracks, and repair if necessary. This AD also requires installing a placard and revising the airplane flight manual to include procedures to prohibit the application of brakes during backward movement of the airplane. This AD results from a report that an MLG main fitting failed on an airplane that was braking while moving backward. We are issuing this AD to detect and correct cracks in the MLG main fitting, which could result in reduced structural integrity of the MLG main fitting.

Final rule.

2006-06-07 Fokker Services B.V.: Amendment 39-14516. Docket No. FAA- 2005-23476; Directorate Identifier 2005-NM-204-AD.

Effective Date

(a) This AD becomes effective April 26, 2006.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Fokker Model F.28 Mark 0070 and 0100 airplanes, certificated in any category; equipped with Messier-Dowty main landing gears (MLGs).

Unsafe Condition

(d) This AD results from a report that an MLG main fitting failed on an airplane that was braking while moving backward. We are issuing this AD to detect and correct cracks in the MLG main fitting, which could result in reduced structural integrity of the MLG main fitting.

Compliance

(e) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.

Airplane Flight Manual (AFM) Revision and Placard Installation

(f) Within 14 days after the effective date ofthis AD, amend the Limitations section of the Fokker F.28 AFM to prohibit application of brakes during backward movement of the airplane. This may be done by inserting a copy of this AD in the AFM.

Note 1: When a statement to prohibit application of brakes during backward movement of the airplane has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed from the AFM.

(g) Within 14 days after the effective date of this AD, affix a placard on the pedestal, next to the parking brake handle, having the following wording: "APPLICATION OF BRAKES DURING BACKWARD MOVEMENT IS PROHIBITED.''

Inspection and Corrective Action

(h) At the applicable time specified in paragraph (h)(1) or (h)(2) of this AD: Do an eddy current inspection of the MLG main fittings and repair before further flight as applicable, in accordance with the Accomplishment Instructions of Messier-Dowty Service Bulletin F100-32-106, including Appendices A through C and excluding Appendix D, dated February 18, 2005, except as provided by paragraphs (i) and (j) of this AD.

(1) For airplanes on which an inspection has not been done in accordance with Messier-Dowty Service Bulletin F100-32-104, Revision 2, dated October 30, 2003: Within 3 months after the effective date of this AD.

(2) For airplanes on which an inspection has been done in accordance with Messier-Dowty Service Bulletin F100-32-104, Revision 2, dated October 30, 2003: Within 2,000 flight cycles since the last inspection done in accordance with the service bulletin or within 3 months after the effective date of this AD, whichever occurs later.

Exceptions to the Service Bulletin

(i) Where Messier-Dowty Service Bulletin F100-32-106, including Appendices A through C and excluding Appendix D, dated February 18, 2005, specifies contacting the manufacturer for repair: Before further flight, repair using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the Civil Aviation Authority--The Netherlands (CAA-NL) (or its delegated agent).

(j) Although Messier-Dowty Service Bulletin F100-32-106, including Appendices A through C and excluding Appendix D, dated February 18, 2005, specifies to submit certain information to the manufacturer, this AD does not include that requirement.

Parts Installation

(k) As of the effective date of this AD, no person may install, on any airplane, a Messier-Dowty MLG, unless it has been inspected/ repaired according to paragraph (h) of this AD.

Alternative Methods of Compliance (AMOCs)

(l)(1) The Manager, International Branch, ANM-116, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19.

(2) Before using any AMOC approved in accordance with Sec. 39.19 on any airplane to which the AMOC applies, notify the appropriate principal inspector inthe FAA Flight Standards Certificate Holding District Office.

(m) Dutch airworthiness directives 2002-115/2, dated October 8, 2004; and NL-2005-002, dated April 14, 2005, also address the subject of this AD.

Material Incorporated by Reference

(n) You must use Messier-Dowty Service Bulletin F100-32-106, including Appendices A through C and excluding Appendix D, dated February 18, 2005; to perform the actions that are required by this AD, unless the AD specifies otherwise. The Director of the Federal Register approved the incorporation by reference of this document in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain Fokker Model F.28 Mark 0070 and 0100 airplanes. That NPRM was published in the Federal Register on January 4, 2006 (71 FR 293). That NPRM proposed to require inspecting the main landing gear (MLG) main fitting for cracks, and repair if necessary. That NPRM proposed also to require installing a placard and revising the airplane flight manual (AFM) to include procedures to prohibit the application of brakes during backward movement of the airplane.

Comments

We provided the public the opportunity to participate in the development of this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Explanation of Changes to the NPRM

We have added the model number in paragraph (f). We have also corrected a typographical error in paragraph (g) of the AD. We have also corrected the service bulletin name in paragraphs (i) and (j) of the AD, and corrected the service bulletin reference in paragraphs (h), (i) and (j) of the AD.

Conclusion

We have carefully reviewed the available data, and determined that air safety and the public interest require adopting the AD with the changes described previously. We have determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.

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 withinthe 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 have 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 that 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. See the ADDRESSES section for a location to examine the regulatory evaluation.
