**Airworthiness Directives; Agusta S.p.A. Helicopters** 

**AGENCY :**  Federal Aviation Administration (FAA), Department of Transportation (DOT).

**ACTION :**  Final rule; request for
comments.

**SUMMARY :**  We are adopting a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB412 helicopters. This AD requires visually inspecting the main rotor swashplate outer ring (outer ring) for a crack and replacing that outer ring if a crack exists. This AD is prompted by two cases of cracks caused by fatigue on certain outer rings. These actions are intended to prevent the failure of the outer ring, which would lead to loss of main rotor blade pitch control and subsequently loss of helicopter control.

**DATES :**  This AD becomes effective March 12, 2014.

The Director of the Federal Register approved the incorporation by reference of a certain document listed in this AD as of March 12, 2014.

We must receive comments on this AD by April 28, 2014.

Discussion

EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2013– 0152–E, dated July 17, 2013, to correct an unsafe condition for the Agusta Model AB412 helicopter. EASA advises


### 10334 Federal Register / Vol. 79, No. 37 / Tuesday, February 25, 2014 / Rules and Regulations

that two cases of cracks were reported in the outer ring, part number (P/N) 412–010–407–105. A subsequent investigation revealed that ‘‘fatigue failure’’ caused the cracks. EASA states that ‘‘this condition, if not detected and corrected, could lead to the loss of main rotor blade pitch control, possibly resulting in loss of control of the helicopter.’’ EASA calls for repetitive inspections of the affected outer rings for a crack and replacing the outer ring with an improved outer ring, P/N 412– 010–107–117, if a crack is found. If the outer ring has not been replaced, the AD requires replacing each outer ring, P/N 412–010–407–105, with an improved outer ring, P/N 412–010–107–117, within 300 flight hours or 8 months, whichever occurs first. Replacement with an improved outer ring is terminating action for the repetitive inspections, EASA states.

FAA’s Determination

These helicopters have been approved by the aviation authority of Italy and are approved for operation in the United States. Pursuant to our bilateral agreement with Italy, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs.

Related Service Information

AgustaWestland S.p.A. issued Alert Bollettino Tecnico No. 412–134 on July 15, 2013 (BT), to warn that two cases of cracking in the outer ring, P/N 412–010– 407–105, have been reported, both attributed to fatigue failure. The BT calls for visually inspecting the outer ring for a crack with a 5X magnifying glass and a bright light. The BT added that the inspection must occur within 5 flight hours from when the BT was issued and within intervals of 25 flight hours thereafter until the outer ring is replaced. The deadline to replace the outer ring with outer ring, P/N 412– 010–407–117, is 300 flight hours or no later than April 15, 2014, whichever comes first. Outer ring, P/N 412–010– 407–105, was not to be used after April 15, 2014, the BT stated.
AD Requirements

This AD requires:

• Within 5 hours time-in-service (TIS), and thereafter at intervals not to exceed 25 hours TIS, visually inspecting the swashplate outer ring, P/N 412–010– 407–105, for cracks, using a 5X magnifying glass and a bright light. If a crack exists, before further flight, removing the swashplate outer ring from service.

• Within 300 hours TIS or 8 months, whichever occurs first, removing the swashplate outer ring, P/N 412–010– 407–105, from service.

• Not installing a swashplate outer ring, P/N 412–010–407–105, on any helicopter.

Differences Between This AD and the EASA AD

This AD prohibits installation of a swashplate outer ring, P/N 412–010– 407–105, while the EASA AD allows installation of this part under certain conditions. Costs of Compliance

There are no costs of compliance with this AD because there are no helicopters with this type certificate on the U.S. Registry.
FAA’s Justification and Determination of the Effective Date

There are no helicopters with this type certificate on the U.S. Registry. Therefore, we believe it is unlikely that we will receive any adverse comments or useful information about this AD from U.S. Operators.

Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for public comment before issuing this AD are unnecessary because there are none of these products on the U.S. Registry and that good cause exists for making this amendment effective in less than 30 days. 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
We 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, 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. List of Subjects in 14 CFR Part 39

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. The NPRM published in the Federal Register on August 23, 2013 (78 FR 52465). The NPRM was prompted by three reports of cracking in the rear pressure bulkhead (RPBH) web. The NPRM proposed to require inspecting the RPBH web for cracking, and repairing if necessary. We are issuing this AD to detect and correct cracking ofthe RPBH web, which could result in inflight decompression of the airplane and possible injury to the occupants.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0219, dated October 19, 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:

Three reports have been received of a crack in the rear pressure bulkhead (RPBH) web, just below the horizontal beam XI between buttock lines BL425L and BL425R, in the centre web bay below the pressure relief valves.

This condition, if not detected and corrected, could result in an exponential crack growth rate, possibly leading to failureof the affected RPBH web, resulting in inflight decompression of the aeroplane and possible injury to occupants.

A repetitive inspection requirement has been published in issue 10 of Fokker Services [Airworthiness Limitations Section] ALS Report SE–623 under task number 534106– 00–05. The threshold to start this ALS-task is 30,000 [total] flight cycles (FC). However, it is known that many aeroplanes have already exceeded this threshold.
