2017-06961. Airworthiness Directives; Agusta S.p.A.

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to adopt a new airworthiness directive (AD) for Agusta S.p.A. Model A109S helicopters. This proposed AD is prompted by a report of a cabin liner detaching from the helicopter and hitting the main rotor (M/R) blades during flight. This proposed AD would require adding limitations to the rotorcraft flight manual (RFM). The proposed actions are intended to prevent an unsafe condition on these products.

DATES:

We must receive comments on this proposed AD by June 9, 2017.

ADDRESSES:

You may send comments by any of the following methods:

• Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your comments electronically.

We will file in the docket all comments that we receive, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive.

Discussion

EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2015-0227, dated November 19, 2015, to correct an unsafe condition for AgustaWestland S.p.A. Model A109S helicopters. EASA advises of a report that the right-hand lower cabin liner of Internal Arrangement part number (P/N) 109-0814-21-101 detached and hit three main rotor blades during a landing with the right-hand door removed. EASA states that this condition, if not corrected, could lead to further occurrences of in-flight lower cabin liner detachment, possibly resulting in damage to or loss of control of the helicopter. Therefore, the EASA AD requires revising the RFM to provide limitations on flights with a passenger cabin sliding door opened or removed. EASA considers its AD an interim action and states further AD action may follow.

FAA's Determination

This helicopter has been approved by the aviation authority of Italy and is 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 its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other helicopters of the same type design.

Related Service Information

We reviewed AgustaWestland A109S RFM, Document No. 109G0040A013, Issue 2, Revision 3, dated April 23, 2015, which adds several limitations regarding flight with a passenger cabin sliding door opened or removed.

Proposed AD Requirements

This proposed AD would require, within 15 hours time-in-service, revising the Limitations section of the RFM by inserting a copy of this AD or by making pen-and-ink changes to add several limitations: Prohibiting flight with a passenger cabin sliding door opened or removed for helicopters with Internal Arrangement P/N 109-0814-21-101 installed; prohibiting flight with a passenger cabin sliding door open unless modification P/N 109-0814-35 is installed; prohibiting flight with a passenger cabin sliding door open unless the doors are locked; establishing a maximum V_NE with a passenger cabin sliding door opened or removed; establishing a maximum airspeed for opening or closing a passenger cabin sliding door during flight; and prohibiting instrument flight rule operation with any door opened or removed.

Interim Action

We consider this proposed AD to be an interim action. The design approval holder is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, we might consider additional rulemaking.

Costs of Compliance

We estimate that this proposed AD would affect 19 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. At an average labor rate of $85 per work-hour, revising the RFM would take about 0.5 work-hour, for an estimated cost of $43 per helicopter, or $817 for the U.S. fleet.

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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD 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.

For the reasons discussed, I certify 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); (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 proposed AD and placed it in the AD docket.
