Models named: EC135P3 or EC135T3. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Airbus Helicopters Deutschland GmbH Model EC135P1, EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, and EC135T3 helicopters, certificated in any category, with autopilot installed, having serial numbers (S/Ns) up to 1263 inclusive, 1265, and 2001 up to 2024 inclusive, but excluding S/N 2006, 2008, 2013, 2017, 2019, 2020, and 2022. Note 1 to Paragraph (c): Helicopters with an EC135P3H or EC135T3H designation are Model EC135P3 or EC135T3 helicopters, respectively.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD 2018-0063, dated March 22, 2018 (EASA AD 2018-0063).

Unsafe condition

This AD was prompted by a reassessment of the flight control system, which revealed that uncommanded disengagement of the main rotor trim actuators during flight with the autopilot engaged and hands-off controls could result in high roll and pitch rates requiring pilot intervention within a reaction time below that required by current airworthiness standards. The FAA is issuing this AD to require installing a cyclic stick weight compensation modification to correct this unsafe condition, which if not corrected, could result in subsequent loss of control of the helicopter.

Affected ADs

None.
