What to do
Operators of SOLO 2625 02i engines with affected ECU software must update the software within three months of 27 March 2020, following SOLO Kleinmotoren GmbH Service Bulletin 4600-11 instructions. From the effective date, installation of affected software on any ECU or engine is prohibited. Requests for alternative compliance methods can be submitted to EASA if substantiated.
Summary
EASA Airworthiness Directive 2020-0056 is an official directive addressing the SOLO 2625 02i engine with electronic fuel injection, commonly installed on Binder Motorenbau, DG-Flugzeugbau, and Schempp-Hirth powered sailplanes. This directive mandates an update to the engine control unit (ECU) software to correct a fuel injection error. The update ensures continued airworthiness and safe operation of affected engines.
What changed
EASA Airworthiness Directive 2020-0056 introduces a mandatory update to the ECU software for SOLO 2625 02i engines. The update replaces affected software versions V517 Revision 7 and earlier with version V517R8 or later. It prohibits installation of any ECU with the affected software from the effective date onward.
Why it matters
This directive is critical for aviation professionals because the identified ECU software error can cause unintended fuel injection, potentially delaying engine restart in flight and reducing control of powered sailplanes. Operators and maintenance organizations must comply to maintain safety and regulatory compliance, preventing operational risks associated with engine control failures.
