4/10 complexity

This Airworthiness Directive orders operators of Thielert TAE 125‑01 “a.m.” engines fitted with a clutch (and listed in Thielert Service Bulletin TM TAE 125‑0011 Rev 3) to replace the clutch assembly or the clutch friction plate following the manufacturer’s repair manual. Compliance is required before the next flight after the AD’s effective date (30 June 2005).

Aircraft owners or operators must arrange and pay for the replacement; the Civil Aviation Safety Authority issued the AD and cites an LBA Airworthiness Directive as related authority.
