Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule.

SUMMARY:

This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Beech Model 58 Start Printed Page 75608airplanes. This AD requires you to inspect the rudder bellcrank interconnect tube for damage; replace or refinish the interconnect tube, if necessary; and modify the floorboard. Four reports of damage to the interconnect tube prompted this action. The actions specified by this AD are intended to correct the wrong use of screws and consequent wear in the pilot/copilot pedal interconnect tube, which could result in loss of rudder control.

DATES:

This AD becomes effective on December 29, 2000.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of December 29, 2000.

SUPPLEMENTARY INFORMATION:

Discussion

What events have caused this AD? The FAA has received four reports of grooves cut in the pilot/copilot rudder interconnect tube. The grooves were discovered during routine inspections.

What are the consequences if the condition is not corrected? This condition could result in jamming or restricting rudder control.

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 certain Raytheon Beech Model 58 airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on September 7, 2000 (65 FR 54184). The NPRM proposed to require you to inspect the rudder bellcrank interconnect tube for damage; if necessary, replace or refinish the rudder bellcrank interconnect tube; and plug the floorboard screw hole.

Was the public invited to comment? Interested persons were afforded an opportunity to participate in the making of this amendment. No comments were received on the proposed rule or the FAA's determination of the cost to the public.

The 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 determined that these minor corrections:

—will not change the meaning of the AD; and

—will not add any additional burden upon the public than was already proposed.

Cost Impact

How many airplanes does this AD impact? We estimate that this AD affects 491 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 the modification of the floorboard and inspection of the rudder bellcrank interconnect tube:

Labor costParts costTotal cost per airplaneTotal cost on U.S. airplane operators
4 workhours × $60 per hour = $240Parts are provided at no charge under warranty$240 per airplane$240 × 491 = $117,840.

We estimate the following costs to accomplish the modification or replacement of the bellcrank interconnect tube:

Labor costParts costTotal cost per airplaneTotal cost on U.S. airplane operators
1 workhour × $60 per hour = $60Parts are provided at no charge under warranty$60 per airplane$60 × 491 = $29,460.

Note:

The manufacturer will allow warranty credit for labor and parts to the extent noted in the service bulletin.

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.
