Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule.

SUMMARY:

This amendment supersedes Airworthiness Directive (AD) 77-15-06, which applies to all SOCATA—Groupe AEROSPATIALE (Socata) Models MS 892A-150, MS 892E-150, MS 893A, MS 893E, Rallye 150T, and Rallye 150ST airplanes. AD 77-15-06 currently requires you to repetitively inspect the engine mount assembly for cracks, repair any cracks found, and modify the brackets on airplanes with right angle engine mounts. This AD is the result of the French airworthiness authority's determination that updated service information and additional aircraft should be added to the applicability of AD 77-15-06. This AD retains the inspection and repair requirements of the current AD and adds the information communicated by the French airworthiness authority. The actions specified by this AD are intended to detect and correct cracks in the engine mount assembly. Such a condition could cause the engine mount assembly to fail, which could result in loss of control of the airplane.

DATES:

This AD becomes effective on April 22, 2002.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of April 22, 2002.

Discussion

Has FAA Taken Any Action to This Point?

Fatigue cracks found on the engine mount assemblies of Socata Models MS 892A-150, MS 892E-150, MS 893A, MS 893E, Rallye 150T, and Rallye 150ST airplanes caused us to issue AD 77-15-06, Amendment 39-2975. AD 77-15-06 currently requires the following:

—Inspecting the engine mount assembly for cracks at repetitive intervals;

—Repairing any cracks found; and

—Modifying the brackets on airplanes with right angle engine mounts.

What Has Happened Since AD 77-15-06 To Initiate This Action?

The Direction Generale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, recently notified FAA of the need to change AD 77-15-06. The DGAC reports that:

—The manufacturer has issued new service information to address the unsafe condition;

—Additional airplane models should be added to the applicability; and

—The initial compliance time should be changed from 100 hours time-in-service (TIS) to 50 hours TIS.

What Is the Potential Impact if FAA Took No Action?

This condition, if not detected and corrected, could cause the engine mount assembly to fail. Such failure could result in loss of control of the airplane.

Has FAA Taken Any Action to This Point?

We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to all Socata Models MS 892A-150, MS 892E-150, MS 893A, MS 893E, MS 894A, MS 894E, Rallye 150T, and Rallye 150ST airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on December 17, 2001 (66 FR 64928). The NPRM proposed to supersede AD 77-15-06 with a new AD that would require you to:

—Repetitively inspect any engine mount assembly that is not part number 892-51-0-035-0 (or FAA-approved equivalent part number) for cracks;

—Repair cracks that do not exceed a certain length; and

—Replace the engine mount when the cracks exceed a certain length and cracks are found on an engine mount that already has two repairs.

Was the Public Invited To Comment?

The FAA encouraged interested persons to participate in the making of this amendment. We did not receive any comments on the proposed rule or on our determination of the cost to the public.

FAA's Determination

What Is FAA's Final Determination on This Issue?

After careful review of all available information related to the subject presented above, we have determined that air safety and the public interest require the adoption of the rule as proposed except for minor editorial corrections. We have determined that these minor corrections:

—Provide the intent that was proposed in the NPRM for correcting the unsafe condition; and

—Do not add any additional burden upon the public than was already proposed in the NPRM. Start Printed Page 10832

Cost Impact

How Many Airplanes Does This AD Impact?

We estimate that this AD affects 81 airplanes in the U.S. registry.

What Is the Cost Impact of This AD on Owners/Operators of the Affected Airplanes?

We estimate the following costs to accomplish each inspection:

Labor costParts costTotal cost per airplaneTotal cost on U.S. operators
1 workhour × $60 = $60No parts required$60$60 × 81 = $4,860

We estimate the following costs to accomplish any necessary repairs that will be required based on the results of each inspection. We have no way of determining the number of airplanes that may need such repair:

Labor costParts costTotal cost per airplane
3 workhours × $60 = $180No parts required$180

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

Labor costParts costTotal cost per airplane
9 workhours × $60 = $540$3,500$540 + $3,500 = $4,040

Regulatory Impact

Does This AD Impact Various Entities?

The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132.

Does This AD Involve a Significant Rule or Regulatory Action?

For the reasons discussed above, I certify that this action (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. A copy of the final evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
