AD 2005-26-01

The FAA is adopting a new airworthiness directive (AD) for certain Dassault Model Falcon 2000 airplanes. This AD requires an inspection for the presence of fail-safe pins, nuts, and washers on each engine, and replacement of the fail-safe fastener assembly with a new assembly if necessary. This AD results from a report of a missing pin of a fail-safe fastener. We are issuing this AD to prevent reduced structural integrity of an engine mount due to a missing pin of a fail- safe fastener, and possible separation of an engine from the airplane during flight.

Final rule.

2005-26-01 Dassault Aviation: Amendment 39-14422. Docket No. FAA- 2005-22633; Directorate Identifier 2005-NM-155-AD.

Effective Date

(a) This AD becomes effective January 24, 2006.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Dassault Model Falcon 2000 airplanes, certificated in any category; up to and including serial number 212, excluding serial number 208.

Unsafe Condition

(d) This AD results from a report of a missing pin of a fail- safe fastener. We are issuing this AD to prevent reduced structural integrity of an engine mount due to a missing pin of a fail-safe fastener, and possible separation of an engine from the airplane during flight.

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.

Inspection and Replacement

(f) Before the accumulation of 3,750 total landings, or within 2 months after the effective date of this AD, whichever occurs later: Do a detailed inspection for the presence of fail-safe pins, nuts, and washers on each engine, in accordance with the Accomplishment Instructions of Dassault Service Bulletin F2000-301, dated February 2, 2005. If any component is found missing at an attachment point, before further flight, replace the fail-safe fastener assembly with a new assembly, in accordance with the service bulletin.

Note 1: For the purposes of this AD, a detailed inspection is: "An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required."

(g) Inspections and replacements done in accordance with Chapter 54-003, dated December 2002, of the Dassault Falcon 2000 Maintenance Manual are acceptable for compliance with the requirements of paragraph (f) of this AD.

No Reporting

(h) Although the service bulletin referenced in this AD specifies to submit certain information to the manufacturer, this AD does not include that requirement.

Alternative Methods of Compliance (AMOCs)

(i)(1) The Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, 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 in the FAA Flight Standards Certificate Holding District Office.

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 Dassault Model Falcon 2000 airplanes. That NPRM was published in the Federal Register on October 7, 2005 (70 FR 58634). That NPRM proposed to require an inspection for the presence of fail-safe pins, nuts, and washers on each engine, and replacement of the fail-safe fastener assembly with a new assembly if necessary.

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.

Conclusion

We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed.

Costs of Compliance

This AD will affect about 149 airplanes of U.S. registry. The required inspection will take about 1 work hour per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the inspection required by this AD for U.S. operators is $9,685, or $65 per airplane.

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 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.
