Federal Aviation Administration (FAA), DOT.
We are adopting a new airworthiness directive (AD) for Agusta S.p.A. Model A109S helicopters. This AD requires adding limitations to the rotorcraft flight manual (RFM). This AD was prompted by a report of a cabin liner detaching from the helicopter and hitting the main rotor (M/R) blades during flight. The actions of this AD are intended to prevent an unsafe condition on these products.
This AD is effective September 5, 2017.

Start Supplemental Information
On April 10, 2017, at 82 FR 17156, 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 Agusta S.p.A. Model A109S helicopters. The NPRM proposed to 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 part number (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 VNE 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.
The NPRM was prompted by AD No. 2015-0227, dated November 19, 2015, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for the AgustaWestland S.p.A. Model A109S helicopters. EASA advises of a report that the right-hand lower cabin liner of Internal Arrangement P/N 109-0814-21-101 detached and hit three M/R 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.
We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM.
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 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 the same type design and that air safety and the public interest require adopting the AD requirements as proposed.
We consider this 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.
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.
Costs of Compliance
We estimate that this AD affects 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 takes 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 helicopters identified in this rulemaking action.
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.
