Germany-based developer Lilium has submitted a full set of means of compliance proposals to the European Union Aviation Safety Agency (EASA) for the type certification of the Lilium Jet.
The means of compliance are an essential part of the programme by which an aircraft manufacturer demonstrates a new aircraft type conforms with airworthiness requirements prescribed in the certification basis previously identified by EASA.
EASA's type certification process consists of technical familiarisation and certification basis; establishment of the certification programme; and compliance demonstration.
Lilium completed the first step and received its EASA certification basis (CRI-A01) in 2020. As part of the second step, EASA and Lilium are required to define and agree on the means to demonstrate compliance of the aircraft type with each requirement of the certification basis. Submitting means of compliance proposals to EASA represents an important milestone towards completion of that second step and moves Lilium closer to type certification of the Lilium Jet.
Before any newly developed aircraft model enters into operation, it must obtain type certification from the responsible airworthiness authority. Lilium is pursuing type certification for the Lilium Jet with EASA and concurrent type certification validation with the US Federal Aviation Administration under the provisions of the Bilateral Aviation Safety Agreement between the EU and US.
