What events have caused this AD? Raytheon recently notified FAA that a Beech Model A36 airplane did not have sealant between the faying surfaces of the part number (P/N) 109-361023-13 tube assembly fitting and the P/N 36-430054-69 upper firewall panel. Raytheon found this condition during a routine production process inspection.

Other airplanes that were part of this particular production process are:

Beech Model A36: Serial numbers E-3113 through E-3231, E-3233 through E-3263, E-3265 through E-3267, E-3269, E-3271, E-3273, and E3277

Beech Model B36TC: Serial numbers EA-594 through EA-644

What are the consequences if the condition is not corrected? This condition, if not corrected, could result in smoke or fire penetrating the firewall and entering the flight compartment or cabin.

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 A36 and B36TC airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on August 16, 2000 (65 FR 49952). The NPRM proposed to require you to inspect for the installation of firewall sealant; and install firewall sealant if not present.

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.

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.

How many airplanes does this AD impact? We estimate that this AD affects 134 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 inspection:

We estimate the following costs to accomplish the modification:

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.

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:
