Ampaire, Ikhana Team on Electrified Twin Otter Plan
Two innovative companies have joined forces in a NASA-funded project to create a hybrid electric Twin Otter variant

Ampaire, a developer of hybrid electric aircraft propulsion, has teamed with Ikhana Aircraft Services to explore modifying Twin Otter airframes to fly with that technology. California-based Ikhana is known for engineering modifications for Twin Otters, including having received an FAA supplemental type certificate for its DHC-6-300HG with a maximum gross weight increase to 14,000 pounds, from 12,500 pounds.
