EASA Approves New AEVEX Aerospace Twin Otter STC

Solana Beach, CA, September 29, 2021  AEVEX Aerospace, a full-spectrum provider of innovative aircraft, remote sensing, and analysis solutions to government and commercial clients, has announced that the European Union Aviation Safety Agency (EASA) approved a new Supplemental Type Certificate (STC) allowing installation of a 250 Amp High-Flow Starter Generator in DHC-6 Twin Otter aircraft. “Previously approved as FAA STC SA02730LA, this new approval expands the market of our 250A High-Flow Starter Generator; we are able to increase mission capabilities, provide increased additional value and new revenue opportunities.” states Mr. John A. Zublin, Vice President of Advanced Solutions. “EASA’s STC validation helps operators with aircraft capabilities well beyond the DHC-6’s original starter generator capability. Our 250A High-Flow Starter Generator upgrade is the first fully approved Starter Generator for the DHC-6 Twin Otter series able to provide aircraft with a full 500 Amps of 28 VDC power while in flight. AEVEX’s IKHANA is pleased that we are able to continue growing our list of regulatory approvals bringing availability of this option to Twin Otter operators.”

With this STC, the DHC-6 Twin Otter’s original 200 Amp Starter Generators are replaced with upgraded design generators featuring cast aluminum high-flow axial fans with enhanced cooling ducts, the latest high temperature insulating materials for longer life, improved drive shaft and damper design along with other enhanced components. Straight-forward design provides higher power within the same form and fit envelope as the original units, with no need to remove engines for installation. Scott Starkey, Director of Engineering at IKHANA had this to say about their newest FAA STC approval: “Having this STC approval allows us to bring a much needed product to the worldwide Twin Otter DHC-6 market. In today’s aviation industry, meeting the electrical power need can be challenging. Our 250A High-Flow Starter Generator provides a solution that Twin Otter clients have been asking for and we are happy to deliver 500 AMPS!”
