Discussion

On August 20, 2013, at 78 FR 51127, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to various restricted category helicopters originally manufactured by Bell, Model HH–1K, TH–1F, TH–1L, UH–1A, UH– 1B, UH–1E, UH–1F, UH–1H, UH–1L, and UH–1P, with a cable assembly, part number 205–001–720–001 installed. The current type certificate holders for these models include but are not limited to Arrow Falcon Exporters Inc.; AST, Inc.; Bell Helicopter Textron, Inc.; Global Helicopter Technology, Inc.; Hagglund Helicopters, LLC; International Helicopters, Inc.; JJASPP Engineering Services, LLC; Northwest Rotorcraft, LLC; OAS Parts LLC; Richards Heavylift Helo, Inc.; Robinson Air Crane, Inc.; Rotorcraft Development Corporation; San Joaquin Helicopters; Smith Helicopters; Southern Helicopter, Inc.; Southwest Florida Aviation International, Inc.; Tamarack Helicopters, Inc.; and Southwest Florida


### 9386 Federal Register / Vol. 79, No. 33 / Wednesday, February 19, 2014 / Rules and Regulations

Aviation, Inc. The NPRM proposed to require inspecting each cable assembly to determine if an incorrectly machined body is installed. If an incorrectly machined body is installed, the NPRM proposed to require replacing the cableassembly within 50 hours time-inservice. Until the cable assembly is replaced, the NPRM proposed to require inspecting the assembly for separation daily.

The proposed requirements were intended to prevent disengagement of the cable from the body, T/R pitch control failure in a fixed position, and subsequent loss of control of the helicopter.

Comments

We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM (78 FR 51127, August 20, 2013).

FAA’s Determination

We have reviewed the relevant information and determined that an unsafe condition exists and is likely to exist or develop on other products of the same type design and that air safety and the public interest require adopting the AD requirements as proposed.

Related Service Information

We reviewed Bell Alert Service Bulletin No. UH–1H–12–08, dated August 28, 2012 (ASB), which describes procedures for inspecting the barrel assembly to determine if an incorrectly machined body is installed. If an incorrectly machined body is installed, the ASB specifies replacing the cable assembly. The ASB further specifies inspecting the barrel assembly and cable connection daily until the cable assembly is replaced.

Differences Between This AD and the Service Information

The ASB specifies inspecting the barrel assembly at the next daily inspection; this AD specifies inspecting within 25 hours TIS. The ASB also specifies replacing any defective cable assembly at the next phase inspection, within 50 hours TIS, or by December 31, 2012; this AD specifies replacing the cable assembly within 50 hours TIS.
Costs of Compliance

We estimate that this AD will affect 716 helicopters of U.S. Registry. We estimate that operators will incur the following costs in order to comply with this AD. At an average labor rate of $85 per hour, inspecting the barrel assembly requires about 1 work-hour, for a cost per helicopter of $85 and a total cost of $60,860 for the fleet. If required, replacing a defective cable assembly requires about 8 work-hours, and required parts cost about $625, for a cost per helicopter of $1,305.
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.
Regulatory Findings

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 this AD:

(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);

(3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and

(4) 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 and placed it in the AD docket.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain ATR—GIE Avions de Transport Re  ́ gional Model ATR42 and Model ATR72 airplanes. The NPRM published in the Federal Register on September 25, 2013 (78 FR 58967). The NPRM was prompted by reports of defective sealing between the nacelle lower fairing and the underwing box.The NPRM proposed to require a onetime general visual inspection for damaged (worn, torn, or abraded) or missing seals between the nacelle lower fairing and the underwing box of both the left-hand and right-hand engine nacelles, and replacement of the seal and/or shims if necessary. We are issuing this AD to prevent the decrease of the fire extinguishing agent efficiency, which could delay fire extinction and allow fire propagation out of the nacelle fire protected area, resulting in damage to the airplane.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0160, dated August 24, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI

states:

Some cases of defective sealing have beenreported on in-service aeroplanes on LeftHand (LH) and Right-Hand (RH), between the nacelle lower fairing and the underwing box.

Investigation results have shown that this issue was due to either damaged or missing seal and/or incorrect adjustment of the nacelle lower fairing.

This condition, if not detected and corrected, may decrease the extinguishing agent efficiency, delay the fire extinction and allow fire propagation out of the nacelle fire protected area, possibly resulting in damage to the aeroplane.

For the reasons described above, this [EASA] AD requires a one-time [general visual] inspection of the affected area [between the nacelle lower fairing and the underbox wing for damaged (worn, torn, or abraded) or missing seals] and, depending on findings, accomplishment of applicable corrective actions to restore the area integrity.
