    Rotax 912 iSc2 Sport, 912 iSc3 Sport and Rotax 915 iSc3 A engines, all serial numbers (s/n).
    These engines are known to be installed on, but not limited to, various general aviation aeroplane
    types and models. The installation of these engines was either done by the respective aeroplane
    manufacturer, or through modification of the aeroplane by Supplemental Type Certificate (STC).
    For the purpose of this AD, the following definitions apply:
    The ASB: BRP-Rotax Alert Service Bulletin (ASB) ASB-912 i-011 / ASB-915 i A-008 (single document).
    Affected part: Fuel pump assemblies, having part number (P/N) 889696 (part of assembly
    P/N 889697) or P/N 889698 (part of assembly P/N 889699), and having an s/n from 180500 to
    192699 inclusive
    Serviceable part: Any fuel pump assembly which is not an affected part.
    Groups: Group 1 engines are those that have an affected part installed. Group 2 engines are those
    that do not have an affected part installed.
    Deviations in manufacturing process have been reported, which could lead to malfunction of fuel
    supply. Subsequent investigation identified the batch of affected fuel pumps.
    This condition, if not corrected, could lead to engine in-flight shut down, possibly resulting in a
    forced landing with consequent damage to the aeroplane and injury to occupants.
    To address this potential unsafe condition, BRP-Rotax issued the ASB, providing instructions to
    replace affected parts.
    Previously, EASA issued Emergency AD 2019-0055-E, requiring, for some of the fuel pumps affected
    by the unsafe condition addressed by this AD, inspections and, depending on findings, replacement.
    For the reason described above, this AD supersedes EASA Emergency AD 2019-0055-E and requires
    replacement of the affected parts and prohibits further (re)installation thereof.
    Required Action(s) and Compliance Time(s):
    Required as indicated, unless accomplished previously:
    (1) For Group 1 engines: Before next flight after the effective date of this AD, replace each affected
    part with a serviceable part in accordance with the instructions of the ASB.
    Part(s) Installation:
    (2) For Group 1 and Group 2 engines: From the effective date of this AD, do not install on any
    engine an affected part, as defined in this AD.
