Federal Aviation Administration, DOT.
Notice of proposed rulemaking (NPRM).
This document proposes adopting a new airworthiness directive (AD) for Eurocopter France (ECF) Model EC120B helicopters. This proposal would require installing front and side covers to protect the yaw control. This proposal is prompted by the report of a mobile phone falling between the Start Printed Page 6887windshield canopy (canopy) and the cabin floor jamming the yaw control pedal. The actions specified by this proposed AD are intended to prevent an object from sliding between the canopy and the cabin floor, loss of yaw control, and subsequent loss of control of the helicopter.
Comments must be received on or before April 15, 2002.
Submit comments in triplicate to the Federal Aviation Administration (FAA), Office of the Regional Counsel, Southwest Region, Attention: Rules Docket No. 2001-SW-68-AD, 2601 Meacham Blvd., Room 663, Fort Worth, Texas 76137. You may also send comments electronically to the Rules Docket at the following address: firstname.lastname@example.org. Comments may be inspected at the Office of the Regional Counsel between 9 a.m. and 3 p.m., Monday through Friday, except Federal holidays.Start Further Info

Availability of NPRMs
Any person may obtain a copy of this NPRM by submitting a request to the FAA, Office of the Regional Counsel, Southwest Region, Attention: Rules Docket No. 2001-SW-68-AD, 2601 Meacham Blvd., Room 663, Fort Worth, Texas 76137.
The Direction General De L'Aviation Civile (DGAC), the airworthiness authority for France, notified the FAA that an unsafe condition may exist on this model helicopter. The DGAC advises of a report of a yaw control jamming caused by an object that slid between the canopy and the cabin floor.
ECF has issued Alert Service Bulletin No. 67A005, dated July 30, 2001 (ASB), which specifies installing a front and side protection on the cabin floor to protect the yaw control. The DGAC classified this ASB as mandatory and issued AD No. 2001-386-007(A), dated September 5, 2001, to ensure the continued airworthiness of these helicopters in France.
This helicopter model is manufactured in France and is type certificated for operation in the United States under the provisions of 14 CFR 21.29 and the applicable bilateral agreement. Pursuant to the applicable bilateral agreement, the DGAC has kept the FAA informed of the situation described above. The FAA has examined the findings of the DGAC, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States.
This unsafe condition is likely to exist or develop on other helicopter models of the same type design registered in the United States. Therefore, the proposed AD would require installing front and side covers to protect the yaw control. The actions would be required to be accomplished in accordance with the ASB described previously.
The FAA estimates that 44 helicopters of U.S. registry would be affected by this proposed AD, that it would take approximately 2 work hours per helicopter to accomplish the proposed actions, and that the average labor rate is $60 per work hour. Required parts would cost approximately $851. Based on these figures, the total cost impact of the proposed AD on U.S. operators is estimated to be $42,724.
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 proposal would not have federalism implications under Executive Order 13132.
For the reasons discussed above, I certify that this proposed regulation (1) is not a “significant regulatory action” under Executive Order 12866; (2) is not a “significant rule” under the 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 regulatory 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.Start List of Subjects

The Proposed Amendment
Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration proposes to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:Start Part
PART 39—AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
2. Section 39.13 is amended by adding a new airworthiness directive to read as follows:
Eurocopter France: Docket No. 2001-SW-68-AD.
Applicability: Model EC120B helicopters, serial numbers 1001 through 1278, inclusive, certificated in any category.
This AD applies to each helicopter identified in the preceding applicability provision, regardless of whether it has been otherwise modified, altered, or repaired in the area subject to the requirements of this AD. For helicopters that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.Start Printed Page 6888
Compliance: Required within 90 days, unless accomplished previously.
To prevent an object from sliding between the canopy and the cabin floor, loss of yaw control, and subsequent loss of control of the helicopter, accomplish the following:
(a) Install front and side covers (protections) to protect the yaw control in accordance with the Accomplishment Instructions, paragraph 2.B., Alert Service Bulletin No. 67A005, dated July 30, 2001 (ASB) except the correct reference to the Aircraft Maintenance Manual in subparagraph 2.B.2 of the ASB is 20-10-00, 3-8. If the helicopter has flight controls at both the pilot and co-pilot stations, front and side protections are required at both stations.
Figure 1 of the ASB depicts the right-hand side of the cockpit.
(b) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Regulations Group, Rotorcraft Directorate, FAA. Operators shall submit their requests through an FAA Principal Maintenance Inspector, who may concur or comment and then send it to the Manager, Regulations Group.
Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Regulations Group.
(c) Special flight permits may be issued in accordance with 14 CFR 21.197 and 21.199 to operate the helicopter to a location where the requirements of this AD can be accomplished.
The subject of this AD is addressed in Direction Generale De L'Aviation Civile (DGAC) 2001-386-007(A), dated September 15, 2001.
Issued in Fort Worth, Texas, on February 6, 2002.
