Airworthiness Directives; Raytheon Aircraft Company (The Beech Aircraft Company and BEECH Previously Held Type Certificate Nos. 3A15, 3A16, 5A3, and A-777) Models 35-33, 35-A33, 35-B33, 35-C33, E33, F33, G33, 35-C33A, E33A, F33A, E33C, F33C, 35, A35, B35, C35, D35, E35, F35, G35, H35, J35, K35, M35, N35, P35, S35, V35, V35A, V35B, 36, A36, A45 (T-34A, B45), D45 (T-34B), 95-55, 95-A55, 95-B55, 95-B55A, 95-B55B (T- 42A), 95-C55, 95-C55A, D55, D55A, E55, E55A, 56TC, A56TC, 58, 95, B95, B95A, D95A, and E95 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: We propose to supersede Airworthiness Directive (AD) 72-22-01, which applies to certain Raytheon Aircraft Company (RAC) (The Beech Aircraft Company and BEECH previously held Type Certificate Nos. 3A15, 3A16, 5A3, and A-777) Models 33, 35, 36, 45, and 95 series airplanes. AD 72-22-01 currently requires you to determine if each uplock roller is of the greasible type (one having a drilled and grooved inner race), replace any nongreasible uplock roller (one having a solid inner race) with the greasible type before further flight, install hollow zerk- ended mounting bolts on the uplock rollers, and repetitively lubricate the uplock mechanism. Since we issued AD 72-22-01, there was a recent incident involving a RAC Model 95-B55B (T-42A) airplane where a seizure of the uplock rollers occurred. This malfunction of the uplock rollers is addressed in AD 72-22-01. Thus, the FAA has determined that the actions of AD 72-22-01 should also apply to certain serial numbers of the Model 95-B55B (T-42A) airplanes. Consequently, this proposed AD would retain all the actions of AD 72-22-01, would add those Model 95- B55B (T-42A) airplanes to the applicability of this proposed AD, and would list out the specific serial numbers. We are proposing this AD to decrease the possibility of gear-up landings caused by seizure of the uplock rollers.
DATES: We must receive comments on this proposed AD by February 9, 2007.

Discussion
Reports of RAC 33, 35, 36, 45, and 95 series airplanes equipped with non-greasible uplock rollers having a solid inner race that renders lubrication of the uplock roller mechanism ineffective
[[Page 71495]]
caused us to issue AD 72-22-01, Amendment 39-1544 (37 FR 22371, October 19, 1972). AD 72-22-01 currently requires the following on certain RAC 33, 35, 36, 45, and 95 series airplanes:
Determining if each uplock roller is of the greasible type (one having a drilled and grooved inner race);
Replacing any nongreasible uplock roller (one having a solid inner race) with the greasible type before further flight;
Installing a hollow zerk-ended mounting bolts on the uplock rollers; and
Repetitively lubricating the uplock mechanism.
Since we issued AD 72-22-01, there was a recent incident involving a RAC Model 95-B55B (T-42A) airplane where a seizure of the uplock rollers occurred. The design of the uplock rollers is the same as those uplock rollers on the airplanes addressed by AD 72-22-01.
This condition, if not corrected, could result in a gear-up landing.
Relevant Service Information
We have reviewed Beechcraft Service Instructions No. 0448-211, Rev. I, and Beechcraft Service Instructions No. 0448-211.
The service information describes procedures for:
Determining if each uplock roller is of the greasible type (one having a drilled and grooved inner race);
Replacing any nongreasible uplock roller (one having a solid inner race) with the greasible type before further flight;
Installing a hollow zerk-ended mounting bolts on the uplock rollers; and
Repetitively lubricating the uplock mechanism.
FAA's Determination and Requirements of the Proposed AD
We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would supersede AD 72-22-01 with a new AD that would retain all the actions of AD 72-22-01, would add those Model 95-B55B (T-42A) airplanes to the applicability of this proposed AD, and would list out the specific serial numbers. This proposed AD would require you to use the service information described previously to perform these actions.
Costs of Compliance
We estimate that this proposed AD would affect 9,714 airplanes in the U.S. registry.
The differences in costs between this proposed AD and AD 72-22-01 are the costs associated with the number of Model 95-B55B (T-42A) airplanes that were not affected by AD 72-22-01.
We estimate the following costs to do the proposed actions to determine if each uplock roller is of the greasible type (one having a drilled and grooved inner race), replace any nongreasible uplock roller (one having a solid inner race) with the greasible type before further flight, install hollow zerk-ended mounting bolts on the uplock rollers, and initially lubricate the uplock mechanism:
Total cost Total cost on Labor cost

U.S. airplane operators
2 work-hours x $80 per hour =

We estimate the following costs for each lubrication of the uplock mechanism.
Total cost Total cost on Labor cost
Parts cost per
U.S. airplane operators
1 work-hour x $80 per hour =

$777,120 $80..........................
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, ``General requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
Regulatory Findings
We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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.
For the reasons discussed above, I certify that the proposed regulation:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
-
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.
We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the proposed AD, the regulatory evaluation, any comments received, and other information on the Internet at http://dms.dot.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m.,

Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647-5227) is located at the street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.
