LAA Alert for some models of Rotax Engines

LAA Alert A-02-2025 has been published on the LAA website (and is also attached), highlighting a recent service bulletin published by Rotax regarding the inspection and/or replacement of the crankcase and/or gearbox housing on affected engines.

Rotax has identified a potential manufacturing issue affecting the hardness values of the crankcase and/or gearbox housing materials in certain engines. These components may not meet the required specifications for material hardness, which could lead to reduced component durability and/or potential oil leakage. Rotax regards this bulletin as mandatory.
