SUPPLEMENTARY INFORMATION:
Background The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to Airbus Helicopters Model EC130B4 and Model EC130T2
helicopters. The NPRM published in the Federal Register on July 7, 2021 86 FR
35695. In the NPRM, the FAA proposed to require, within 90 hours time-inservice TIS after the effective date of the AD, or before the next autorotation training flight, whichever occurs first, removing the protective boot along the collective and measuring the clearance between the collective tab hook hook and low pitch locking pin pin. If the clearance is less than 5 mm 0.196 in, adjusting the clearance between the hook and the pin to prevent interference was proposed. The NPRM then proposed to require re-installing the protective boot in accordance with the manufacturers service information. The NPRM was prompted by EASA AD
20170062, dated April 11, 2017 EASA
AD 20170062, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Airbus Helicopters Model EC130B4 and EC130T2 helicopters. EASA states that during an autorotation test conducted during an acceptance flight, the pilot felt a jamming sensation when pushing

the collective to the low pitch position, and he subsequently was able to free the collective by pulling on it. According to EASA, an analysis determined that the hook and the pin were extremely close, and that a fold in the control lever boot may have become caught between the two components. EASA states that this condition, if not detected and corrected, could result in an untimely locking of the collective and subsequent reduced control of the helicopter.
Accordingly, EASA AD 20170062
requires inspecting and adjusting, if necessary, the clearance between the hook and the pin while in the low pitch position.
Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs.
Conclusion 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 reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on these helicopters.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Airbus Helicopters Alert Service Bulletin ASB No. EC130
67A019, Revision 0, dated February 23, 2016, which specifies inspecting and adjusting the clearance between the hook and pin.
This service information 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.
Differences Between This AD and the EASA AD
The EASA AD requires compliance within 165 hours TIS or 3 months, whichever occurs first. Since the unsafe condition occurred at a collective position commanded during an autorotation, this AD requires compliance within 90 hours TIS after
