Critical response engineering (CRAS)
Approved engineering support - fast when it matters
Grounded aircraft? We get you flying again – fast. We provide you with CRAS Support and Flight Conditions under EASA Part 21J DOA. Specially designed for you when time is of critical importance - with fast decisions, approved data and practical implementation support. When standard maintenance paths are no longer sufficient, we offer services to all commercial Airbus and Boeing aircraft models. This includes the corresponding engine installations as well as approved solutions covering structural, avionics, and systems topics.
Our Part 21J Support is an EASA-certified, faster, and fully capable alternative to Airbus's RDAS and Boeing's RDR. This service enables the direct, compliant approval of urgent structural or systemic modifications and repairs without time-consuming detours. By leveraging immediate on-site engineering and certification expertise, you minimize aircraft downtime and maximize fleet availability while maintaining the highest safety and quality standards.
We accelerate turnaround, and consolidating repair authority under one single, independently certified engineering organization.
