Federal Aviation Administration, DOT.
Notice of proposed rulemaking (NPRM).
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain SOCATA—Groupe AEROSPATIALE (SOCATA) Model TBM 700 airplanes. This proposed AD would require you to install a new strainer draining system in the cabin fuselage. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by this proposed AD are intended to prevent water from accumulating in the fuselage, then freezing and interfering with or causing the elevator controls to seize. This could result in loss of elevator control with consequent loss of airplane control.
The Federal Aviation Administration (FAA) must receive any comments on this proposed rule on or before December 12, 2001.
Submit comments to FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2001-CE-10-AD, 901 Locust, Room 506, Kansas City, Missouri 64106. You may view any comments at this location between 8 a.m. and 4 p.m., Monday through Friday, except Federal holidays.
You may get service information that applies to this proposed AD from SOCATA-Groupe AEROSPATIALE, Customer Support, Aerodrome Tarbes-Ossun-Lourdes, BP 930-F65009 Tarbes Cedex, France; telephone: (33) (0)220.127.116.11.00; facsimile: (33) (0)18.104.22.168.54; or the Product Support Manager, SOCATA—Groupe AEROSPATIALE, North Perry Airport, 7501 Pembroke Road, Pembroke Pines, Florida 33023; telephone: (954) 894-1160; facsimile: (954) 964-4191.

How do I comment on this proposed AD? The FAA invites comments on this proposed 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 to the address specified under the caption ADDRESSES. We will consider all comments received on or before the closing date. We may amend this proposed rule in light of comments received. Factual information that supports your ideas and suggestions is extremely helpful in evaluating the effectiveness of this proposed AD action and determining whether we need to take additional rulemaking action.
Are there any specific portions of this proposed AD I should pay attention to? The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this proposed rule that might suggest a need to modify the rule. You may view 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 contactwe have with the public that concerns the substantive parts of this proposed AD.
How can I be sure FAA receives my comment? If you want FAA to acknowledge the receipt of your comments, you must include a self-addressed, stamped postcard. On the postcard, write “Comments to Docket No. “2001-CE-10-AD.” We will date stamp and mail the postcard back to you.
What events have caused this proposed AD? The Direction Générale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, recently notified FAA that an unsafe condition may exist on certain SOCATA Model TBM 700 airplanes. The DGAC reports an incident in which the elevator controls jammed on one of the affected airplanes.
Jamming of the elevator controls occurred because water accumulated in the fuselage and froze. Water had accumulated in the fuselage because the strainer and draining hole became clogged.
What are the consequences if the condition is not corrected? If this condition is not corrected, water may accumulate in the fuselage, freeze and interfere with or cause the elevator controls to seize. This could result in loss of elevator control.
Is there service information that applies to this subject? ocata has issued Service Bulletin SB 70-082 53, dated June 2000.
What are the provisions of this service information? The service bulletin includes procedures for installing a new strainer draining system in the cabin fuselage.
What action did DGAC take? The DGAC classified this service bulletin as mandatory and issued French AD 2000-373(A), dated October 18, 2000, in order to assure the continued airworthiness of these airplanes in France.
Was this in accordance with the bilateral airworthiness agreement? This airplane model is manufactured in France and is type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept FAA informed of the situation described above.
The FAA's Determination and an Explanation of the Provisions of This Proposed AD
What has FAA decided? The FAA has examined the findings of the DGAC; reviewed all available information, including the service information referenced above; and determined that:
—The unsafe condition referenced in this document exists or could develop on other Socata Model TBM 700 airplanes of the same type design;
—The actions specified in the previously-referenced service information should be accomplished on the affected airplanes; and
—AD action should be taken in order to correct this unsafe condition.
What would this proposed AD require? This proposed AD would require you to incorporate the actions in the previously-referenced service bulletin.
How many airplanes would this proposed AD impact? We estimate that this proposed AD affects 79 airplanes in the U.S. registry.
What would be the cost impact of this proposed AD on owners/operators of the affected airplanes? We estimate the following costs to accomplish this proposed modification:
|Labor cost||Parts cost||Total cost per airplane||Total cost on U.S. operators|
|2 workhours × $60 = $120||$114||$234||$18,486|
Compliance Time of This Proposed AD
What would be the compliance time of this proposed AD? The compliance time of this proposed AD is “within the next 3 months after the effective date of this AD”.
Why is the compliance time presented in calendar time instead of hours time-in-service (TIS)? Although water in the cabin fuselage could interfere with the elevator controls and become unsafe during flight, the condition is not a direct result of airplane operation. The chance of this situation occurring is the same for an airplane with 10 hours time-in-service (TIS) as it would be for an airplane with 500 hours TIS. A calendar time for compliance will assure that the unsafe condition is addressed on all airplanes in a reasonable time period.
Would this proposed AD impact various entities? The regulations proposed herein 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. Therefore, it is determined that this proposed rule would not have federalism implications under Executive Order 13132.
Would 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 DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated, 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 draft Start Printed Page 57009regulatory evaluation prepared for this action has been placed in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.Start List of Subjects
