Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Notice of proposed rulemaking (NPRM); Extension of the comment period.

SUMMARY:

This document provides additional time for the public to comment on a proposal to adopt a new airworthiness directive (AD) that would apply to certain Cessna Aircraft Company (Cessna) 150, 172, 175, 180, 182, 185, 206, 210, and 336 series airplanes. The proposed AD would affect those airplanes equipped with 0513166 series plastic control wheels. The proposed AD would require you to repetitively inspect these wheels for cracks, conduct a pull test on these wheels, and replace any control wheels that are cracked or that do not pass the pull test. Replacement of the control wheels would be with ones that are FAA-approved and are not 0513166 series plastic control wheels. The proposed AD is the result of many incidents of control wheels cracking or breaking on the above-referenced airplanes. Comments received on the original notice of proposed rulemaking (NPRM) specify additional time to respond to the proposed action. The actions specified by the proposed AD are intended to detect and correct cracked or defective control wheels, which could result in loss of control of the airplane during takeoff, landing, or ground operations.

DATES:

The Federal Aviation Administration (FAA) must receive any comments on this proposed rule by April 4, 2001. This is extended from February 2, 2001.

ADDRESSES:

Send three copies of comments to the Federal Aviation Administration (FAA), Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 98-CE-57-AD, 901 Locust, Room 506, Kansas City, Missouri 64106. You may read comments at this location between 8 a.m. and 4 p.m., Monday through Friday, except holidays.

You may get the service information referenced in the proposed AD from Cessna Aircraft Company, Product Support, P.O. Box 7706, Wichita, Kansas 67277; telephone: (316) 517-5800; facsimile: (316) 942-9006. You may read this information at the Rules Docket at the address above.

Comments Invited

How do I comment on this proposed AD? We invite your comments on the proposed rule. You may send whatever written data, views, or arguments you choose. You need to include the rule's docket number and send your comments in triplicate to the address named under the caption ADDRESSES. We will consider all comments received by the closing date named above, before acting on the proposed rule. We may change the proposals contained in this notice because of the comments received.

Are there any specific portions of the proposed AD I should pay attention to? The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of the proposed rule that might call for a need to change the proposed rule. You may look at all comments we receive. We will file a report in the Rules Docket that summarizes each FAA contact with the public that concerns the substantive parts of this proposal.

The FAA is reexamining the writing style we currently use in regulatory documents, in response to the Presidential memorandum of June 1, 1998. That memorandum requires federal agencies to communicate more clearly with the public. We are interested in your comments on the ease of understanding this document, and any other suggestions you might have to improve the clarity of FAA communications that affect you. You can get more information about the Presidential memorandum and the plain language initiative at http://www.faa.gov/​language/​.

How can I be sure FAA receives my comment? If you want us to Start Printed Page 6500acknowledge the receipt of your comments, you must include a self-addressed, stamped postcard. On the postcard, write “Comments to Docket No. 98-CE-57-AD.” We will date stamp and mail the postcard back to you.

Discussion

What events have caused this proposed AD? The FAA has received reports of many incidents of control wheels cracking or breaking on Cessna 150, 172, 175, 180, 182, 185, 206, 210, and 336 series airplanes. The problem control wheels are 0513166 series plastic control wheels.

The cause of this problem is because of temperature variations in the molding process during manufacture of the control wheels and deterioration with age and temperature extremes.

This condition could result in the control wheels breaking while the airplane is in operation. A consequent loss of control of the airplane during takeoff, landing, or ground operations could occur.

We issued an NPRM that proposed to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Cessna Aircraft Company (Cessna) 150, 172, 175, 180, 182, 185, 206, 210, and 336 series airplanes. The NPRM would require you to:

—Repetitively inspect and pull test the 0513166 series control wheels; and

—If necessary, replace any control wheels that fail the inspection or pull test.

What has happened to cause FAA to issue this document? We received comments on the NPRM indicating the need for more time to provide data on the proposed AD. Based on these comments and the interest in the rule expressed by various operators and other interested parties, FAA has decided to extend the comment period on this rule to seek additional data. Therefore, the comment period is extended approximately 60 days and will close April 4, 2001.

We are including additional preamble information and the actual AD for the reader's convenience.

What are the differences between the service bulletin and the proposed AD? The Cessna service letter specifies inspecting and testing the control wheels as soon as possible and positively by the next 100-hour inspection. We propose that you inspect and pull test the control wheels and replace (if necessary) the control wheels within 100 hours time-in-service (TIS) after the effective date of this proposed AD, and then at intervals not to exceed 12 months until the control wheels are replaced.

We believe that these compliance times will give the owners or operators of the affected airplanes enough time to have the proposed actions performed without compromising the safety of the airplanes.

Cost Impact

How many airplanes would this proposed AD impact? We estimate the proposed AD would affect 12,592 airplanes in the U.S. registry.

What would be the cost impact of the proposed AD on owners/operators of the affected airplanes? We estimate the following costs to do the proposed inspection and pull test:

Labor costParts costTotal cost per airplaneTotal cost on U.S. operators
1 hour at $60 for each hourNo parts are required1 hour x $60 = $6012,592 airplanes × $60 for each airplane = $755,520.

We estimate the following costs to do any necessary control wheel replacements that would be required based on the results of the proposed inspection and pull test. We have no way of determining the number of airplanes that may need such control wheel replacement:

Labor costParts costTotal cost per airplane
1 hour at $60 for each hour$597 for each control wheel$60 + $597 = $657.

These figures only consider the cost of the first inspection and test and do not account for repetitive inspections and tests. We do not have any means of finding out the number of repetitive inspections and tests the owner/operator would incur over the life of an affected airplane.

Regulatory Impact

How would this proposed AD impact various entities? The proposed regulations would not have substantial direct effects 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. We have determined that this proposed rule would not have federalism implications under Executive Order 13132.

Does this proposed AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this proposed action (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under Department of Transportation Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) if put into effect, will not have a significant economic impact, positive or negative, on a large number of small entities under the criteria of the Regulatory Flexibility Act. We have placed a copy of the draft regulatory evaluation prepared for this action in the Rules Docket. You may get a copy of it by contacting the Rules Docket at the location provided under the caption ADDRESSES.

Start Printed Page 6502
ActionsCompliance timesProcedures
(1) Check your maintenance records to determine whether this AD applies to your airplane by doing the following: (i) Check the maintenance records to determine whether a 0513166 series plastic control wheel is installed. The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may check the maintenance records. (ii) If, by checking the maintenance records, the pilot can positively show that no 0513166 series plastic control wheels are installed, then the inspection, testing, and replacement requirements of this AD do not apply. The AD is complied with after you make an entry into the aircraft records that shows compliance with this portion of the AD, in accordance with section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).Required within 100 hours time-in-service (TIS) after the effective date of this ADNo special procedures required to check the maintenance records.
(2) For any affected airplane where at least one 0513166 series plastic control wheel is installed, do the following: (i) Inspect each control wheel for cracks; and (ii) Conduct a pull test on each control wheelBefore further flight after the maintenance records check or within 100 hour TIS after the effective date of this AD, and reinspect afterward at intervals not to exceed 12 months until all control wheels are replaced with FAA-approved control wheels that are not 0513166 series plastic control wheelsDo this following the instructions of Cessna Service Letter No. 64-8, dated February 14, 1964.
(3) Replace any cracked control wheel or any control wheel that does not pass any pull test, with an FAA-approved control wheel that is not a 0513166 series plastic control wheelDo this replacement before further flight after the inspection where the cracked or failed control wheel is foundDo the replacements following the instructions in the applicable maintenance or service manual.
(4) Do not install, on any affected airplane, a 0513166 series plastic control wheelAs of the effective date of this ADNot Applicable.
(5) You may replace all control wheels with wheels that are not part number 0513166, as terminating action for the repetitive inspection and test requirement of this ADYou may replace all control wheels at any time, except for those control wheels that are cracked or do not pass a pull test. Such wheels must be replaced prior to further flight, as required by paragraph (d)(3) of this ADDo the replacements following the instructions in the applicable maintenance or service manual.

(e) Can I comply with this AD in any other way? You may use an alternative method of compliance or adjust the compliance time if:
