Background The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD
20180280, dated December 17, 2018
EASA AD 20180280, to correct an unsafe condition for Leonardo S.p.a.
formerly Finmeccanica S.p.A., AgustaWestland S.p.A., Agusta S.p.A.;
and AgustaWestland Philadelphia Corporation, formerly Agusta Aerospace Corporation Model A109A, A109A II, A109C, A109E, A109K2, A109S, A109LUH, AW109SP, A119, and AW119 MKII helicopters. Model A109LUH helicopters are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those helicopters in the applicability.
This proposed AD was prompted by a report of damage to a rod, and loosening of the nut on the upper rod end. The FAA is proposing this AD to address damage to the rod, and loosening of the nut on the upper rod end, which could result in failure of the rod, possibly resulting in reduced control of the helicopter. See EASA AD
20180280 for additional background information.
Related Service Information Under 1
CFR Part 51
EASA AD 20180280 requires a visual inspection of the affected rods for damage, cracks, or evidence of abnormal play, and, depending on findings, any applicable corrective actions which include replacing damaged or cracked connecting links and actions to address abnormal play.

This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.
FAAs Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAAs bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of these same type designs.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified in EASA AD 20180280, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD.
Explanation of Required Compliance Information In the FAAs ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation authority CAA
ADs as the primary source of information for compliance with requirements for corresponding FAA
ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate EASA AD 20180280 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 20180280
in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD.
Using common terms that are the same as the heading of a particular section in EASA AD 20180280 does not mean that operators need comply only with that section. For example, where the AD
requirement refers to all required actions and compliance times, compliance with this AD requirement is not limited to the section titled Required Actions and Compliance Times in EASA AD 20180280.
Service information required by EASA
AD 20180280 for compliance will be available at https www.regulations.gov by searching for and locating Docket No.
FAA20210659 after the FAA final rule is published.
