SUPERSEDED BY EASA AD 2025-0220
Summary
EASA Airworthiness Directive 2025-0112-E is an emergency directive affecting all serial numbers of DG-1000T powered sailplanes. It addresses a critical safety issue involving propeller separation due to failure of the damper element rubber. The directive prohibits operation of the powerplant and mandates specific placard installations and flight manual amendments to mitigate the risk.
What Changed
This new directive introduces an immediate operational restriction on the powerplant of DG-1000T powered sailplanes following two reported incidents of propeller separation. It requires amending the flight manual to prohibit engine use and installing 'Motor INOP' placards. It also allows removal of the powerplant as an alternative compliance method.
Why It Matters
This directive is crucial for aviation professionals as it addresses a potentially catastrophic failure that could lead to structural damage, loss of control, and injury to people on the ground. Operators and maintenance teams must comply promptly to ensure continued airworthiness and safety. The directive is an interim measure pending further investigation, emphasizing the need for vigilance and adherence to updated procedures.
What To Do
Operators must cease powerplant operation on DG-1000T powered sailplanes from 16 May 2025. Within 7 days of this date, they must amend the flight manual as per DG Aviation Service Information 116-25 and install 'Motor INOP' placards accordingly. Alternatively, removing the powerplant following the maintenance manual is acceptable for compliance.
