LAA Alert A-03-2025 has been published on the LAA website (and is also attached), highlighting the recent service bulletin, JSP 051, published by Jabiru Aircraft Pty Ltd, which applies to specific Jabiru 2200 and 3300 engines and requires the replacement of the pistons on engines within certain serial number ranges, which they state were supplied between April 2017 and August 2019. Jabiru regards the Bulletin as mandatory.
The Bulletin advises that Jabiru has identified that pistons supplied with the affected engines were in some cases susceptible to failure, and have specified that the pistons must be replaced by pistons of the later, improved design at or before 200 hours running time, following the procedures shown in the engine overhaul book, including any necessary running-in provisions and choice of oils.
