- On uninstalled engines: before the initial installation.
- On installed engines: Carry out this inspection before next flight on the engines listed in section 
1.1, according to the instructions in section 3, but at the latest after 1 year (from the date of the 
initial issue of this Alert Service Bulletin).
1.6) Approval
The technical content of this document is approved under the authority of the DOA ref. 
EASA.21J.048. 
1.7) Labor time
A labor credit will be provided for work performed by a technician with current applicable iRMT rat-
ing. To apply for labor credit, contact your ROTAX® Authorized Distributor or their independent Ser-
