What to do
Operators of Rotax 912 iSc2 Sport, 912 iSc3 Sport, and 915 iSc3 A engines must inspect the specified fuel pump assemblies before the next engine operation after 20 March 2019. If any defects are found during inspection, the affected parts must be replaced before further engine use. Only serviceable fuel pump assemblies, as defined by the directive, may be installed on any engine from the effective date onward.
Summary
EASA Airworthiness Directive 2019-0055-E is an emergency directive addressing a fuel pump assembly issue in BRP-Rotax GmbH & Co KG Rotax 912 iSc2 Sport, 912 iSc3 Sport, and 915 iSc3 A engines. The directive mandates inspection and possible replacement of specific fuel pump assemblies identified by part numbers 889696 and 889698 with serial numbers from 180500 to 189999. These engines are commonly installed on various general aviation aircraft either by original manufacturer installation or Supplemental Type Certificate modifications.
What changed
EASA Airworthiness Directive 2019-0055-E introduces a one-time inspection requirement for affected fuel pump assemblies due to a manufacturing defect causing fuel leaks. It also sets conditions for the installation of serviceable fuel pump assemblies on affected engines. The directive was republished to correct a typographical error in the compliance section.
Why it matters
This directive is critical for aviation professionals because undetected fuel leaks in the affected fuel pump assemblies could lead to engine fires, posing serious safety risks including forced landings and potential injuries. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and prevent hazardous incidents. The directive also clarifies installation requirements to avoid future occurrences of the defect.
