SUMMARY: This amendment adopts a new airworthiness directive (AD) for the Aeronautical Accessories, Inc. (AAI) Low Skid Landing Gear Forward Crosstube (Crosstube) on certain Bell and Agusta model helicopters. This action requires replacing certain AAI serial-numbered crosstubes installed on these model helicopters. This amendment is prompted by the discovery of a defect in the raw material used in manufacturing certain crosstubes. The actions specified in this AD are intended to prevent failure of a crosstube and subsequent collapse of the landing gear. DATES: Effective June 8, 2010. Comments for inclusion in the Rules Docket must be received on or before July 23, 2010.

SUPPLEMENTARY INFORMATION: This amendment adopts a new AD for the Bell Model 205A, 205A–1, 205B, 212, 412, 412EP, and 412CF and Agusta Model AB412, AB412EP helicopters. This action requires replacing certain AAI serial-numbered crosstubes installed on these model helicopters. This amendment is prompted by AAI’s discovery of a defect in a batch of raw material used in the manufacture of these crosstubes. Preliminary tests indicate that surface cracking on the inner wall of the tubing was introduced during the manufacturing process. There have been no failures reported in the field. The defect was discovered during the forming operation at AAI. This condition, if not corrected, could result in failure of a crosstube and subsequent collapse of the landing gear. We have reviewed AAI Alert Service Bulletin No. AA–10012, dated March 5, PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 2010 (ASB), which describes a possible defect in the material used to manufacture the crosstube, part number (P/N) 212–320–103, which is also included as part of AAI Low Skid Gear Assembly Kits, P/N 412–320–500 and 412–320–502. The ASB specifies locating the serial number (S/N) of each crosstube, and replacing, within 25 hours time-in-service (TIS), each crosstube within the S/N range of AA– 574 through AA–628, by following the replacement procedures contained in the Instructions for Continued Airworthiness AA–01136. This unsafe condition is likely to exist or develop on other helicopters of these same type designs with an affected crosstube. Therefore, this AD is being issued to prevent failure of a crosstube and subsequent collapse of the landing gear. This AD requires, within 25 hours TIS, replacing any affected crosstube with an airworthy crosstube. The short compliance time involved is required because the previously described critical unsafe condition can adversely affect the structural integrity of the helicopter. Therefore, replacing any affected crosstube with an airworthy crosstube is required within 25 hours TIS, and this AD must be issued immediately. Since a situation exists that requires the immediate adoption of this regulation, it is found that notice and opportunity for prior public comment hereon are impracticable, and that good cause exists for making this amendment effective in less than 30 days. We estimate that this AD will affect 19 helicopters, and replacing each affected crosstube will take about 5 work hours at an average labor rate of $85 per work hour. Required parts will cost about $4,925 per helicopter. Based on these figures, we estimate the total cost impact of the AD on U.S. operators to be $101,650.

SUPPLEMENTARY INFORMATION: This amendment adopts a new AD for the Bell 
Model 205A, 205A-1, 205B, 212, 412, 412EP, and 412CF and Agusta Model 
AB412, AB412EP helicopters. This action requires replacing certain AAI 
serial-numbered crosstubes installed on these model helicopters. This 
amendment is prompted by AAI's discovery of a defect in a batch of raw 
material used in the manufacture of these crosstubes. Preliminary tests 
indicate that surface cracking on the inner wall of the tubing was 
introduced during the manufacturing process. There have been no 
failures reported in the field. The defect was discovered during the 
forming operation at AAI. This condition, if not corrected, could 
result in failure of a crosstube and subsequent collapse of the landing 
gear.
    We have reviewed AAI Alert Service Bulletin No. AA-10012, dated 
March 5, 2010 (ASB), which describes a possible defect in the material 
used to manufacture the crosstube, part number (P/N) 212-320-103, which 
is also included as part of AAI Low Skid Gear Assembly Kits, P/N 412-
320-500 and 412-320-502. The ASB specifies locating the serial number 
(S/N) of each crosstube, and replacing, within 25 hours time-in-service 
(TIS), each crosstube within the S/N range of AA-574 through AA-628, by 
following the replacement procedures contained in the Instructions for 
Continued Airworthiness AA-01136.
    This unsafe condition is likely to exist or develop on other 
helicopters of these same type designs with an affected crosstube. 
Therefore, this AD is being issued to prevent failure of a crosstube

    Since a situation exists that requires the immediate adoption of

making this amendment effective in less than 30 days.
    We estimate that this AD will affect 19 helicopters, and replacing 
each affected crosstube will take about 5 work hours at an average 
labor rate of $85 per work hour. Required parts will cost about $4,925 
per helicopter. Based on these figures, we estimate the total cost

Regulatory Findings

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD 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.
    For the reasons discussed above, I certify that the 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 11032, February 26, 1979); and
    3. 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD. See the AD docket to examine the economic evaluation.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
subtitle VII, part A, subpart III, section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.
