EASA AD 2022-0044R1
Engine — Modification / Inspection
Summary
EASA Airworthiness Directive 2022-0044R1 is an updated regulatory document addressing safety concerns related to Solo 2350 C and 2350 D engines installed on DG-Flugzeugbau Model DG-1000T and certain Schempp-Hirth powered sailplanes. It mandates modifications and inspections of specific excentre shaft/axle parts to prevent shaft failure and propeller detachment. The directive applies to all manufacturer serial numbers of these engines and includes life limits and installation prohibitions for affected parts.
What Changed
EASA AD 2022-0044R1 revises the previous AD 2022-0044 by removing the 30-day calendar time limitation for modifying Solo 2350 D engines and deletes inspection requirements for removed affected parts. It introduces a 30-hour life limit for the old excentre axles and clarifies that modification is only required before the affected part exceeds 30 operating hours. The revision refines compliance timelines and removes inspection and reporting obligations that were outside the scope of the AD.
Why It Matters
This directive is critical for aviation professionals to ensure the continued airworthiness and safety of sailplanes powered by Solo 2350 C and 2350 D engines. Compliance prevents potential catastrophic failures such as shaft rupture and propeller detachment, which could cause damage to aircraft and injury to persons. Operators and maintenance teams must understand the updated modification schedules and life limits to maintain regulatory compliance and safe operation.
What To Do
Operators must modify Solo 2350 C engines before the next flight after 31 March 2015 if not already modified, and modify Solo 2350 D engines before the affected part or engine exceeds 30 operating hours. After modification, serviceable parts must be replaced before exceeding 50 hours of operation. Installation of affected parts is prohibited from 29 March 2022 onward. Compliance with these requirements is mandatory unless previously accomplished.
