SUMMARY: The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed adopting a new airworthiness directive (AD) for Bell Helicopter Textron (Bell) Model 206B helicopters modified with Aeronautical Accessories, Inc. (AAI) Supplemental Type Certificate (STC) No. SH8435SW or SH8419SW with energy attenuating seat installation wire (energy attenuating wire). The proposed AD would have required replacing certain energy attenuating wire with airworthy energy attenuating wire. Since issuing the proposed AD, we have determined that no unsafe condition exists with respect to the STC installed energy attenuating wire. Accordingly, the proposed AD is withdrawn.

(MDHI) Model MD900 series helicopters. The AD would require modifying the pilot and co-pilot dual-control directional pedal assemblies, or the pilot singlecontrol directional pedal assembly (directional control pedal assembly). This proposal is prompted by an accident which has been attributed to loss of directional control due to failure of the welds in the directional control pedal assembly. The actions specified by the proposed AD are intended to prevent fatigue cracking in the welds that connect the directional control pedal to the pedal shaft, resulting in loss of directional control and subsequent loss of control of the helicopter.

The Docket Office (telephone 1–800–647– 5227) is located at the plaza level of the Department of Transportation Nassif Building in Room PL–401 at 400 Seventh Street, SW., Washington, DC. Comments will be available in the AD docket shortly after the DMS receives them. Discussion This document proposes adopting a new AD for MDHI Model MD900 series helicopters, serial numbers (S/N) 900– 00008 through 900–00111, 900–00113, and 900–00114. The AD would require modifying the directional control pedal assembly by removing the existing pedals, removing the welded pedal support plate from the pedal shafts, installing a new pedal mount on each pedal shaft using rivets, reinstalling the pedals on the new pedal mounts, and marking the modified directional control pedal assembly with a part number. This proposal is prompted by an accident which has been attributed to loss of directional control due to failure of the welds in the directional control pedal assembly. The actions specified by the proposed AD are intended to prevent fatigue cracking in the welds that connect the directional control pedal to the pedal shaft, resulting in loss of directional control and subsequent loss of control of the helicopter. We have reviewed MD Helicopters Service Bulletin SB900–100, dated April 5, 2006, which describes procedures for modifying the directional control pedal assembly. This unsafe condition is likely to exist or develop on other helicopters of the same type design. Therefore, the proposed AD would require modifying the directional control pedal assembly, part number (P/N) 900C1012007–107, –109, –111, –113, or 900C6012007–111 (pilot dual control); or P/N 900C1012207–105, –107, –109, –111, or –113 (co-pilot dual control); or P/N 900C1010007–107, –109, –111, –113, or 900C6010007–111 (pilot single control), by removing the existing pedals, removing the welded pedal support plate from the pedal shafts, and installing a directional control pedal modification kit, P/N SBK–010. Also, this AD would require ink stamping the P/N, 90005340111–101, on the pedal shaft of each modified directional E:\FR\FM\17OCP1.SGM 17OCP1

SUPPLEMENTARY INFORMATION:

Discussion

    We proposed to amend part 39 of the Federal Aviation Regulations 
(14 CFR part 39) with an NPRM for a new AD for Bell Model 206B 
helicopters with AAI STC No. SH8435SW or SH8419SW. That NPRM was 
published in the Federal Register on October 28, 2005 (70 FR 62085). 
The NPRM would have required replacing energy attenuating wire 
manufactured or invoiced during a specified time frame. The NPRM 
resulted from the disclosure that certain energy attenuating wire may 
not have the yield strength necessary to allow seats to attenuate 
energy during an emergency landing. The proposed actions were intended 
to prevent failure of a seat to attenuate energy during an emergency 
landing and resulting in injury to an occupant.

Actions Since NPRM Was Issued

    Since issuing the NPRM, we have determined that the seat with the 
affected energy attenuating wire will support the occupant adequately 
during an emergency landing and therefore no unsafe condition exists 
for Bell Model 206B helicopters modified with the two STCs.

FAA's Conclusions

    Upon further consideration, we have determined that the actions 
proposed in the NPRM are not needed for Bell Model 206B helicopters. 
Accordingly, the NPRM is withdrawn.
    Withdrawal of the NPRM does not preclude the FAA from issuing 
another related action or commit the FAA to any course of action in the 
future.

Regulatory Impact

    Since this action only withdraws an NPRM, it is neither a proposed 
nor a final rule and therefore is not covered under Executive Order 
12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979).
