EASA TCDS E.251, Issue 01: 114 kW continuous at 1,907–2,300 rpm; 125 kW takeoff for 5 minutes at 1,990–2,300 rpm, with all channels operating. Dry mass 51.6 kg (+1/−0.5). Operating input 510–756.5 VDC. Air cooled; required airflow is specified in the installation manual. Efficiency is defined in that manual rather than the data sheet.
EASA identifies Diamond as the initial airframe customer; the TCDS lists Diamond DA 40 EP installation assumptions. The eFlyer 2 announcement names the ENGINeUS 100 family without identifying B1, so no B1–eFlyer relationship is asserted.
EASA type certificate E.251, 24 January 2025, under SC E-19 Issue 01. Approved for single-engine civil aeroplanes within installation limits. The data sheet lists Diamond DA 40 EP installation assumptions. This engine approval does not approve an aircraft.
