What to do
Operators of Group 1 helicopters must recalculate torque cycles for affected parts within six months of 7 February 2022 and update log-cards accordingly. Replacement of parts must occur before exceeding recalculated service life limits, and Group 3 helicopters must replace specified parts within the same timeframe. Installation of affected parts is permitted only if torque cycles are recalculated and parts are serviceable, with specific restrictions on parts listed in Appendix 1.
Summary
EASA Airworthiness Directive 2022-0012R1 is a regulatory document addressing the recalculation and replacement of mechanical parts based on torque cycles for Airbus Helicopters AS 332 C, C1, L, and L1 models. It mandates updated methods to record torque cycles to prevent underestimation that could lead to structural failure. The directive applies to specific mechanical parts identified by part numbers and requires compliance with revised service life limits.
What changed
This revision supersedes the previous DGAC France AD 88-097-034(B)R2 and introduces updated procedures from Airbus Helicopters Alert Service Bulletin AS332-01.00.76 for recalculating torque cycles. It clarifies that the ASB instructions override earlier service bulletins and establishes new replacement and operational restrictions for affected parts. The AD also defines helicopter groups based on part installation status and sets specific compliance timelines.
Why it matters
This directive is critical for aviation professionals to ensure accurate tracking of mechanical part usage and prevent potential structural failures due to exceeded service life limits. Operators and maintenance organizations must update their maintenance records and procedures to comply with the recalculated torque cycles. Compliance ensures continued airworthiness and operational safety of the affected Airbus Helicopters AS 332 models.
