AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for all Eagle Aircraft (Malaysia) Sdn. Bhd. Model Eagle 150B airplanes. This proposed AD would require you to inspect the port and starboard undercarriage attach bracket for unwelded areas and replace the attach bracket if unwelded areas are found. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Malaysia. We are issuing this proposed AD to detect and correct inadequate welding of the undercarriage, which could result in cracks. This failure could lead to loss of control of the airplane.

DATES:

We must receive any comments on this proposed AD by November 29, 2004.

Discussion

What events have caused this proposed AD? The Department of Civil Aviation, Malaysia (DCA), which is the airworthiness authority for Malaysia, recently notified FAA that an unsafe condition may exist on all Eagle Aircraft Sdn. Bhd. Model Eagle 150B airplanes. The DCA reports one case of finding cracks on a port main undercarriage attach bracket during a routine inspection. An unwelded area on the adjoining plates of the bracket may have caused stress that resulted in the cracking.

What is the potential impact if FAA took no action? Inadequate welding of the undercarriage attach bracket could result in cracks. This failure could lead to loss of control of the airplane.

Is there service information that applies to this subject? Eagle Aircraft Sdn. Bhd. has issued Alert Service Bulletin SB 1123, dated August 8, 2004.

What are the provisions of this service information? The service bulletin includes procedures for inspecting the port and starboard undercarriage attach bracket for unwelded areas.

What action did the DCA take? The DCA classified this service bulletin as mandatory and issued Malaysian CAM AD 001-08-2004 to ensure the continued airworthiness of these airplanes in Malaysia. Start Printed Page 62004

Did the DCA inform the United States under the bilateral airworthiness agreement? These Eagle 150B airplanes are manufactured in Malaysia and are type-certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement.

Under this bilateral airworthiness agreement, the DCA has kept us informed of the situation described above.

FAA's Determination and Requirements of This Proposed AD

What has FAA decided? We have examined the DCA's findings, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States.

Since the unsafe condition described previously is likely to exist or develop on other Eagle 150B airplanes of the same type design that are registered in the United States, we are proposing AD action to detect and correct inadequate welding of the undercarriage attach bracket, which could result in cracks. This failure could lead to loss of control of the airplane.

What would this proposed AD require? This proposed AD would require you to inspect the port and starboard undercarriage attach bracket for unwelded areas in the locations specified in the service information and replace the attach bracket if unwelded areas are found.

How does the revision to 14 CFR part 39 affect this proposed AD? On July 10, 2002, we published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs FAA's AD system. This regulation now includes material that relates to altered products, special flight permits, and alternative methods of compliance. This material previously was included in each individual AD. Since this material is included in 14 CFR part 39, we will not include it in future AD actions.

Costs of Compliance

How many airplanes would this proposed AD impact? We estimate that this proposed AD affects 13 airplanes in the U.S. registry.

What would be the cost impact of this proposed AD on owners/operators of the affected airplanes? We estimate the following costs to accomplish this proposed inspection:

Labor costParts costTotal cost per airplaneTotal cost on U.S. operators
.5 work hours × $65 per hour = $32.50N/A$32.50$422.50

We estimate the following costs to accomplish any necessary replacements that would be required based on the results of this proposed inspection. We have no way of determining the number of airplanes that may need this replacement:

Labor costParts costTotal cost per airplane
1 work hour × $65 per hour = $65If the attach bracket requires replacement, Eagle Aircraft has agreed to provide the parts without cost.$65

Regulatory Findings

Would this proposed AD impact various entities? We have 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.

Would this proposed AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this proposed AD:

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); 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 summary of the costs to comply with this proposed AD and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include “AD Docket FAA-2004-19222; Directorate Identifier 2004-CE-29-AD” in your request.
