AD 2003-01-01

This amendment supersedes Airworthiness Directive (AD) 2000- 26-16, which applies to certain Raytheon Aircraft Company (Raytheon) Beech Models A36, B36TC, and 58 airplanes. AD 2000-26-16 requires you to inspect for missing rivets on the right hand side of the fuselage and, if necessary, install rivets. AD 2000-26-16 resulted from Raytheon identifying several instances of missing rivets on these airplanes. AD 2000-26-16 incorporated an incorrect listing of serial numbers for the affected model airplanes and omitted certain airplane models from the applicability section of AD 2000-26-16. This AD retains the actions required in AD 2000-26-16 and corrects the applicability section. The actions specified by this AD are intended to detect and correct missing rivets in the right hand fuselage panel assembly in the area above the right wing and below the cabin door threshold. These rivets must be present for the fuselage to carry the ultimate load and prevent critical structural failure with loss of airplane control.

DATES: This AD becomes effective on February 27, 2003. The Director of the Federal Register previously approved the incorporation by reference of Raytheon Mandatory Service Bulletin SB 53-3341, Rev. 1, Revised May, 2000, as of February 16, 2001 (66 FR 1253, January 8, 2001).

The Director of the Federal Register approved the incorporation by reference of Raytheon Mandatory Service Bulletin SB 53-3341, Rev. 2, Revised October, 2002, as of February 27, 2003.

Discussion

What Events Have Caused This AD?

Raytheon production and inspection personnel identified several instances of missing rivets on Models A36, B36TC, and 58 airplanes. The missing rivets are the result of a quality control problem. This condition caused us to issue AD 2000-26-16, Amendment 39-12066 (66 FR 1253, January 8, 2001). AD 2000-26-16 requires you to inspect for missing rivets on the right hand fuselage and if necessary, install rivets.

What Has Happened Since AD 2000-26-16 To Initiate This Action?

Raytheon notified FAA that the airplane models and serial numbers listed in Raytheon Mandatory Service Bulletin SB 53-3341, Rev. 1, Revised: May, 2000, and the applicability section of AD 2000-26-16 are incorrect. The serial number designations did not correctly refer to the applicable airplane models. We are adding Beech Models 36, A36TC, and 58A airplanes to the applicability section of this AD to correct this in this document.

What Is the Potential Impact If FAA Took No Action?

This condition, if not corrected, could result in the airplane being unable to carry the ultimate load which could cause structural failure and loss of airplane 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 Models 36, A36, A36TC, B36TC, 58, and 58A airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on August 14, 2002 (67 FR 52894). The NPRM proposed to supersede AD 2000-26-16, Amendment 39-12066, with a new AD that would retain the actions required in AD 2000-26-16 and add certain airplane models to the applicability section of this AD.

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.

The manufacturer has issued Revision 2 to Raytheon Mandatory Service Bulletin SB 53-3341. This service information contains a corrected list of affected airplane models and serial numbers. We will incorporate this service bulletin into the procedures section of this AD.

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.

Cost Impact

How Many Airplanes Does This AD Impact?

We estimate that this AD affects 3,632 airplanesin 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 inspection:

Labor cost
Parts cost
Total cost per airplane
Total cost on U.S. operators
1 workhour x $60 per hour = $60
No parts required for the inspection
$60 per airplane
$60 x 3632 = $217,920

We estimate the following costs to accomplish the modification if necessary:

Labor cost
Parts cost
Total cost per airplane
4 workhours x $60 per hour = $240
$100 per airplane
$340 per airplane

What Is the Difference Between the Cost Impact of This AD and the Cost Impact of AD 2000-26-16?

The only difference between this AD and AD 2000-26-16 is the correction to the applicability. No additional actions are being added. The FAA has determined that this AD action does not increase the cost impact over that already required by AD 2000-26-16.

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 theRules Docket at the location provided under the caption ADDRESSES.
