What to do
Operators of affected AS 350 B3 and EC 130 T2 helicopters must amend the Rotorcraft Flight Manual within specified compliance times, inform flight crews, and operate accordingly. When installing modified FADEC units, the temporary manual amendment must be removed. Installation of affected FADEC parts is prohibited after modification. Compliance deadlines vary by part number, with some requiring action within 30 days or 25 flight hours.
Summary
EASA Airworthiness Directive 2021-0195 is an amendment concerning Airbus Helicopters AS 350 B3 and EC 130 T2 models equipped with ARRIEL 2D engines. It addresses issues related to the Full Authority Digital Engine Control (FADEC) units that may cause in-flight failures affecting fuel flow regulation and engine monitoring displays. The directive mandates changes to the Rotorcraft Flight Manual emergency procedures to improve pilot response to these failures.
What changed
This amendment supersedes EASA AD 2013-0287 and retains its requirements while adding instructions to remove the temporary Rotorcraft Flight Manual amendment for helicopters with modified FADEC units installed. It also prohibits the installation or reinstallation of affected FADEC parts after modification. The directive updates compliance timelines and clarifies affected part numbers and serviceable replacements.
Why it matters
This directive is critical for aviation professionals as it ensures continued airworthiness by addressing a failure mode that could lead to improper pilot response and reduced helicopter control. Operators and maintenance teams must comply to prevent in-flight engine control issues and maintain safety. It also helps in managing part installations to avoid reintroducing known unsafe components.
