Overview
- Bell announced the milestone at European Rotors 2025, citing a single dedicated 505 in the validation program.
- The aircraft has flown on blended SAF at the Bell Training Academy since mid‑2022, accruing all hours on one airframe.
- Engine operability checks, aircraft performance reviews, and detailed inspections have yielded strong, positive results, according to Bell.
- Less than a year after the program launch, the 505 completed a demonstration flight on 100% SAF, the first for a single‑engine helicopter.
- Safran states the Arrius 2R is cleared for up to 50% drop‑in SAF now and projects readiness for 100% drop‑in operation soon.
