Electra.aero Begins FAA Certification for EL9 Hybrid-Electric Aircraft
Electra.aero applies for FAA Part 23 certification of EL9 hybrid-electric eSTOL aircraft with prototype flight planned in 2027 and service in 2029.
This article is based on an official press release from Electra aero.
Electra aero has officially submitted its application to the Federal Aviation Administration (FAA) for Part 23 type certification of its EL9 Ultra Short aircraft. This regulatory filing marks a critical transition for the Virginia-based manufacturer, moving the program from technology demonstration into the formal compliance phase required for commercial operations.
According to the company’s announcement on December 10, 2025, the EL9 is a nine-passenger hybrid-electric aircraft designed for extremely short takeoffs and landings (eSTOL). By entering the certification process, Electra aims to validate its proprietary “blown lift” technology and hybrid propulsion system under the FAA’s modernized airworthiness standards.
The company has outlined a timeline targeting the first flight of a conforming prototype in 2027, with certification and entry into commercial service projected for 2029. Electra reports a substantial backlog for the aircraft, citing over 2,000 pre-orders valued at more than $8 billion from customers including the Bristow Group and various regional carriers.
The EL9 is engineered to operate in a market segment distinct from both traditional helicopters and emerging electric vertical takeoff and landing (eVTOL) vehicles. Electra describes the aircraft as an eSTOL platform capable of taking off and landing in spaces as small as 150 feet (approximately 45 meters). This capability is central to the company’s “Direct Aviation” model, which seeks to utilize infrastructure such as parking lots, barges, and small airfields rather than relying solely on major commercial airports.
Unlike fully electric competitors that require ground-based charging infrastructure, the EL9 utilizes a hybrid-electric powertrain. A turbogenerator charges the batteries in-flight, which powers eight electric motors distributed along the wing’s leading edge. This configuration allows the aircraft to refuel using standard aviation fuel, eliminating the immediate need for grid upgrades at remote landing sites.
According to technical specifications released by the manufacturer, the EL9 offers the following performance metrics:
The aircraft’s short runway performance is achieved through “blown lift” aerodynamics. The distributed electric motors blow air over the wings at high velocity, generating significant lift even at low airspeeds. This allows the EL9 to operate safely at speeds as low as 35 knots, facilitating its ultra-short field performance.
Electra’s application falls under 14 CFR Part 23, the FAA’s set of airworthiness standards for small airplanes. Following Amendment 23-64, these regulations shifted from prescriptive design requirements to performance-based standards. This regulatory framework is essential for integrating novel technologies like distributed electric propulsion, though it often requires manufacturers to define “Special Conditions” with the FAA to prove safety compliance for high-voltage battery systems. The submission of the Part 23 application places Electra in direct competition with other hybrid-electric regional aircraft developers, though their operational profiles differ. Competitors such as Sweden’s Heart Aerospace and France’s Aura Aero are developing larger regional aircraft (the ES-30 and ERA, respectively) that require standard runways. By contrast, Electra’s eSTOL capability targets the gap between these regional fixed-wing aircraft and vertical-lift helicopters.
From an infrastructure perspective, Electra’s choice of a hybrid-electric system offers a strategic deployment advantage. While pure electric aircraft are tethered to the rollout of high-power charging stations, the EL9’s ability to use existing fuel supply chains means it can theoretically enter service immediately upon certification without waiting for airport electrification projects to mature. However, the complexity of certifying a novel blown-lift system alongside a hybrid powertrain remains a significant engineering and regulatory hurdle to clearing the 2029 target.

Frequently Asked Questions
eVTOL (electric Vertical Takeoff and Landing) aircraft take off vertically like helicopters. eSTOL (electric Short Takeoff and Landing) aircraft, like the EL9, require a very short runway (approx. 150 feet) but generally offer higher payload capacity and longer range than eVTOLs.
Electra targets certification and commercial entry into service by 2029, with a prototype first flight planned for 2027.
No. The aircraft uses a hybrid-electric system where an onboard turbogenerator charges the batteries, allowing it to refuel with standard aviation fuel.
