Final rule.
This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Beech Models A36, B36TC, and 58 airplanes. This AD requires you to inspect for missing rivets on the right hand side of the fuselage and, if necessary, install rivets. Raytheon has identified several instances of missing rivets on these airplanes. The actions specified by this AD are intended to install 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.
This AD becomes effective on February 16, 2001.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of February 16, 2001.
You may get the service information referenced in this AD from Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201-0085; telephone: (800) 429-5372 or (316) 676-3140. You may examine this information at the Federal Aviation Administration (FAA), Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 99-CE-79-AD, 901 Locust, Room 506, Kansas City, Missouri 64106; or at the Office of the Federal Register, 800 North Capitol Street, NW, suite 700, Washington, DC.

Raytheon has identified several instances of missing rivets on these airplanes:
| Model | Serial No. |
|---|---|
| Model A36 Bonanza | serials E-1 through E-3231; and E-3233. |
| Model B36TC Bonanza | serials EA-1 through EA-635. |
| Model 58 Baron | serials TH-1 through TH-1811; and TH-1813 through TH-1897. |
Raytheon production and inspection personnel identified the missing rivets. The missing rivets are the result of a quality control problem.
This condition results in the airplane being unable to carry the ultimate load with possible structural failure and loss of airplane control.
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 A36, B36TC, and 58 airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on September 26, 2000 (65 FR 57751). The NPRM proposed to require you to inspect for missing rivets on the right hand fuselage and if necessary, install rivets.
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.
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.
We estimate that this AD affects 3632 airplanes in the U.S. registry.
We estimate the following costs to accomplish the inspection: ( printed page 1254)
| Labor cost | Parts cost | Total cost per airplane | Total cost on U.S. operators |
|---|---|---|---|
| 1 workhour × $60 per hour = $60 | No parts required for the inspection | $60 per airplane | $60 × = $217,920. |
We estimate the following costs to accomplish the modification if necessary:
| Laobor cost | Parts cost | Total cost per airplane |
|---|---|---|
| 4 workouts × $60 per hour = $240 | $100 per airplane | $340 per airplane. |
The manufacturer will allow warranty credit for labor and parts to the extent noted in the service bulletin.
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.
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 .
Accordingly, under the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:
1. The authority citation for part 39 continues to read as follows:
2. FAA amends § 39.13 by adding a new AD to read as follows:
2000-26-16 Raytheon Aircraft Company: Amendment 39-12066; Docket No. 99-CE-79-AD.
(a) What airplanes are affected by this AD? This AD affects the following airplanes, certificated in any category:
| Model | Serial No. |
|---|---|
| Model A36 | E-1 through E-3231, and E-3233. |
| Model B36TC | EA-1 through EA-635. |
| Model 58 | TH-1 through TH-1811, and TH-1813 through TH-1897. |
(b) Who must comply with this AD? Anyone who wishes to operate any of the above airplanes must comply with this AD.
(c) What problem does this AD address? The actions specified by this AD are intended to install missing rivets in the right hand fuselage panel assembly in the area above the right wing and below the cabin door threshold.
