Airworthiness Directives; Leonardo S.p.a. Helicopters Federal Aviation Administration FAA, DOT.
ACTION: Final rule.
AGENCY:

The FAA is adopting a new airworthiness directive AD for certain serial-numbered Leonardo S.p.a.
Leonardo Model A109S and AW109SP
helicopters. This AD requires installing a placard in the baggage compartment, revising the existing Rotorcraft Flight Manual RFM for your helicopter, and inspecting the installation of the terminal lugs. Depending on the outcome of the inspection, this AD
requires restoring the installation of the terminal lugs. This AD would also require modifying the helicopter to shim the baggage fairing assy fwd up away from the circuit breaker panel and incorporating protective coverings. This AD was prompted by reports of several occurrences of fire ignition and smoke in the baggage compartment. The actions of this AD are intended to address an unsafe condition on these products.

SUMMARY:

This AD is effective April 16, 2021.
The Director of the Federal Register approved the incorporation by reference of certain documents listed in this AD
as of April 16, 2021.

SUPPLEMENTARY INFORMATION:
Discussion The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 by adding an AD that would apply to Leonardo Model A109S
helicopters, serial number S/N 22702, 22703, 22705, and 22706 and AW109SP
helicopters with S/N up to 22386
inclusive, except S/N 22375 and S/N
22376. The NPRM published in the Federal Register on December 21, 2020
85 FR 82972. The NPRM proposed to require, before further flight, for certain serial-numbered helicopters, installing a placard and revising the existing RFM
for your helicopter. The NPRM also proposed to require within 5 hours time-in-service TIS, for certain model helicopters, inspecting the installation of the terminal lugs, shimming the installation of the baggage fairing assembly fwd up, and installing a silicon rubber protection over the blind rivets of the hinge in accordance with certain applicable service information.
The NPRM also proposed to require within 10 hours TIS and thereafter at

intervals not to exceed 25 hours TIS
until protective coverings are installed, removing the baggage fairing assembly fwd up, removing the rubber protections, and inspecting the cable assembly routing of both circuit breaker panels for damage. Depending on the outcome of these inspections, the NPRM
proposed to require repairing or replacing certain parts. The NPRM also proposed to require, within 200 hours TIS, modifying the helicopter to incorporate a certain protective coverings, which would provide a terminating action for the repetitive inspections. The proposed requirements were intended to prevent fire in the baggage department.
The NPRM was prompted by EASA
Emergency AD No. 20180120E, dated May 29, 2018 EASA AD 20180120E, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Leonardo S.p.a. formerly Finmeccanica S.p.A., AgustaWestland S.p.A., Agusta S.p.A. Model A109S and AW109SP helicopters. EASA advises that an occurrence was reported on an AW109SP helicopter experiencing fire ignition and smoke in the baggage compartment. The investigation determined the event was due to chafing of electrical wiring and further analysis indicated that due to similarity of design, this event could also occur on A109S helicopters. Accordingly, the EASA AD requires modification of the affected baggage fairing assembly fwd up part number P/N 109034431
101 and temporarily amending the existing RFM and installing a placard prohibiting carrying any loads in the baggage compartment.
After EASA AD 20180120E was issued, a second occurrence was reported of fire ignition and smoke in the baggage compartment, and as a precautionary measure, Leonardo Helicopters issued a series of emergency alert service bulletins providing instructions to prevent damage of electrical assemblies in the baggage compartment. Accordingly, EASA
issued EASA Emergency No. 2018
0149E, dated July 13, 2018 EASA AD
20180149E, which retains the requirements of EASA AD 20180120
E, and also requires repetitive inspections of the baggage compartment electrical assemblies and depending on the inspection outcomes, repairing or replacing certain parts. Also, EASA AD
20180149E expands the applicability to include three additional serialnumbered helicopters, and requires a modification, which acts as a terminating action for the repetitive inspections.
