AD 2021-22-15 Requires Modifying The Hoist Control Power Supply
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332L2 and EC225LP helicopters.
This AD was prompted by a design deficiency. This AD requires modifying the hoist control power supply, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective January 3, 2022.
Supplementary Information: EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0281, dated December 16, 2020 (EASA AD 2020-0281), to correct an unsafe condition for certain serial-numbered Airbus Helicopters (AH), formerly Eurocopter, Eurocopter France, Aerospatiale Model AS 332 L2 and EC 225 LP helicopters.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain serial-numbered Airbus Helicopters Model AS332L2 and EC225LP helicopters. The NPRM published in the Federal Register on August 25, 2021 (86 FR 47420). The NPRM was prompted by a design deficiency involving the incorrect wiring routing of the electrical hoist installation. The affected wiring was not protected by the circuit breaker that was intended to provide electrical protection for that wiring. The NPRM proposed to require modifying the hoist control power supply, as specified in EASA AD 2020-0281.
The FAA is issuing this AD to correct the electrical hoist installation wiring routing. See EASA AD 2020-0281 for additional background information.
