RIN ID: RIN 2120-AA64
SUBJECT CATEGORY: Airworthiness Directives; Maule Aerospace Technology, Inc. M-4, M-5, M-6, M-7, MX-7, and MXT-7 Series Airplanes and Models MT-7-235 and M-8-235 Airplanes
The Federal Aviation Administration (FAA) must receive any comments on this rule on or before June 23, 2000.
DOCUMENT SUMMARY: This amendment adopts a new airworthiness directive (AD) that
applies to certain Maule Aerospace Technology, Inc. (Maule) M4, M5,
M6, M7, MX7, and MXT7 series airplanes and Models MT7235 and M8 235 airplanes. This AD requires you to inspect all
NicopressTM sleeve terminal ends for correct size
compression, with adjustment or replacement, as necessary. This AD
results from a report of the rudder cable slipping out of the
NicopressTM sleeve while one of the affected airplanes was
landing. The actions specified by this AD are intended to detect and
correct improper crimping of the NicopressTM sleeve, which
could cause a control cable to slip from the sleeve. This could result
in loss of rudder, elevator, aileron, or flap control.
SUMMARY: Maule Aerospace Technology, Inc.,
The FAA has received a report of the rudder cable slipping out of the Nicopress\TM\ sleeve while a Maule Model M7235C airplane was landing. Investigation of this accident revealed that the Nicopress\TM\ sleeve was not adequately crimped and was slightly larger than the gauge dimension.
Maule did not set a crimping tool to correct specification for the elevator and rudder cables that were installed on certain Maule airplane models on Type Certificate No. 3A23, Revision 26, dated April 6, 2000. Maule has no way of determining exactly what time frame the crimping tool was not set to specification. Each airplane utilizes approximately 27 Nicopress\TM\ sleeves.
The airplane models affected are listed in the AD portion of this document.
What Are the Consequences if the Condition Is Not Corrected?
An improperly crimped Nicopress\TM\ sleeve, if not detected and corrected, could cause a control cable to slip from the sleeve. This could result in loss of rudder, elevator, aileron, or flap control. Is There Service Information That Applies to This Subject?
Maule has issued Mandatory Service Bulletin No. 20, dated December 27, 1999.
What Are the Provisions of This Service Bulletin?
The service bulletin:
After examining the circumstances and reviewing all available
information related to the incidents described above, including the relevant service information, FAA has determined that:
This AD requires you to inspect all Nicopress\TM\ sleeve terminal
ends for correct size compression, with adjustment or replacement, as necessary.
Will I Have the Opportunity To Comment Prior to the Issuance of the Rule?
Because the unsafe condition described in this document could result in loss of rudder, elevator, aileron, or flap control, FAA finds that notice and opportunity for public prior comment are impracticable. Therefore, good cause exists for making this amendment effective in less than 30 days.
Although this action is in the form of a final rule and was not preceded by notice and opportunity for public comment, FAA invites comments on this rule. You may submit whatever written data, views, or arguments you choose. You need to include the rule's docket number and submit your comments in triplicate to the address specified under the caption ADDRESSES. The FAA will consider all comments received on or before the closing date. We may amend this rule in light of comments received. Factual information that supports your ideas and suggestions is extremely helpful in evaluating the effectiveness of the AD action and determining whether we need to take additional rulemaking action.
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 whether the style of this document is clearer, 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.plainlanguage.gov.
The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify the rule. You may examine all comments we receive before and after the closing date of the rule in the Rules Docket. We will file a report in the Rules Docket that summarizes each FAA contact with the public that concerns the substantive parts of this AD.
If you want us to acknowledge the receipt of your comments, you must include a selfaddressed, stamped postcard. On the postcard, write ``Comments to Docket No. 2000CE04AD.'' We will date stamp and mail the postcard back to you.
These regulations 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, FAA has determined that this final rule does not have federalism implications under Executive Order 13132.
The FAA has determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and is not a significant regulatory action under Executive Order 12866. We have determined that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If FAA determines that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, we will prepare a final regulatory evaluation. You may obtain a copy of the evaluation (if required) from the Rules Docket. List of Subjects in 14 CFR Part 39
