Green Taxi Aerospace Secures Critical FAA Concurrence for Electric Taxi System
Green Taxi Aerospace has achieved a significant regulatory milestone in its bid to decarbonize ground operations, receiving official concurrence from the Federal Aviation Administration (FAA) on its certification plan. This agreement validates the company’s roadmap for its “Zero Engine Taxi” (ZET) system, a retrofit technology designed to allow airliners to taxi without using their main jet engines.
According to the company’s announcement, this concurrence effectively “de-risks” the development program. By aligning with regulators on testing and compliance strategies before the final conforming prototype is built, Green Taxi Aerospace aims to avoid the costly re-engineering pitfalls that have plagued previous attempts at electric taxiing solutions. The approval clears the path for the company to transition from planning into detailed design and hardware fabrication.
The Plano, Texas-based startup, led by former F-16 pilot David Valaer, is targeting a Supplemental Type Certificate (STC) for the Embraer E175 regional jet by late 2027.
Regulatory Alignment Before “Cutting Metal”
In the complex world of aerospace certification, FAA concurrence is a vital “gate” event. It signifies that the regulator has reviewed and accepted the manufacturer’s proposed methods for demonstrating safety and airworthiness. For Green Taxi Aerospace, this means the specific tests and data required to prove the system is safe are now agreed upon.
CEO David Valaer emphasized the strategic importance of this patience-first approach in the company’s statement:
“We touch the APU, we touch the landing gear, we touch the pilot control system. It’s a very complicated project… We’re not going to cut metal until our data is approved by the FAA.”
, David Valaer, CEO of Green Taxi Aerospace
With the certification plan approved, the company has outlined its immediate schedule. Detailed design drawings are slated for completion by mid-2026, followed by the assembly of the first “conforming” prototype, built exactly to the certified design standards, in late 2026. Ground taxi tests on an Embraer E175 are scheduled to begin in 2027.
The “Zero Engine Taxi” Technology
The core of Green Taxi Aerospace’s innovation is a retrofit system that installs electric motors directly onto the aircraft’s main landing gear. Unlike traditional taxiing, which relies on the thrust of massive jet engines optimized for flight, the ZET system uses the aircraft’s existing Auxiliary Power Unit (APU) to power the wheels.
The APU is a small turbine engine located in the tail of the aircraft. While it burns fuel, it is significantly more efficient at ground speeds than main engines. By utilizing the APU, the aircraft can push back from the gate and taxi to the runway with its main engines turned off.
Projected Operational Savings
Green Taxi Aerospace has released data highlighting the potential efficiency gains for operators of the Embraer E175. Regional jets are the primary target because they perform frequent flights with high daily taxi times, maximizing the utility of the system.
According to company projections:
- Fuel Savings: Approximately 80,000 gallons per aircraft, per year.
- Cost Reductions: Estimated savings of $250,000 to $350,000 per aircraft annually, factoring in fuel and maintenance.
- Emissions: An 85% reduction in ground-level carbon emissions compared to single-engine taxiing.
Crucially, the system is designed to be lightweight. The company states the total system weight is under 300 lbs. This is a critical metric; if the system is too heavy, the fuel burned carrying the extra weight during flight could negate the savings achieved on the ground.
Strategic Partnerships
To navigate the certification process, Green Taxi has partnered with StandardAero, a major aerospace maintenance, repair, and overhaul (MRO) provider. StandardAero is leading the certification effort, a move Valaer describes as essential for credibility.
“This partnership with StandardAero positions us for success by aligning our innovative technology with a proven certification partner.”

Contextualizing the Competitive Landscape
While the concept of electric taxiing is not new, Green Taxi Aerospace’s approach attempts to solve the specific engineering hurdles that stalled previous ventures. In 2013, the EGTS joint venture between Safran and Honeywell attempted a similar main-gear concept. However, that system reportedly weighed over 600 lbs and required extensive airframe modifications, which ultimately destroyed the business case.
Green Taxi’s claim of a sub-300 lb system suggests significant advancements in electric motor density over the last decade. By keeping the weight low, they address the primary failure point of the EGTS program.
The company also faces different competition than its predecessors. WheelTug is developing a system that places motors in the nose gear. While this simplifies installation, the nose gear carries less weight, which can limit traction in icy conditions or on slopes. Green Taxi’s decision to power the main gear offers better traction but represents a more complex integration challenge.
Another alternative, TaxiBot, uses semi-robotic tugs to tow planes. While this requires no aircraft modification, it introduces logistical complexity at busy airports, as tugs must return to the gate after every departure. Green Taxi’s onboard solution avoids this congestion but places the capital cost and weight penalty directly on the airline.
With FAA concurrence now secured, Green Taxi Aerospace has cleared the first major hurdle in proving that a lightweight, onboard electric taxi system is not just theoretically possible, but commercially viable.

Southwest Airlines Aircraft Struck by Ground Vehicle at Memphis
A ground equipment vehicle hit a Southwest Airlines jet during boarding at Memphis Airport on June 21, 2026, causing a 4-hour delay.

This is a developing story. Information may change as official details are released.
This article summarizes reporting by Fox News Digital and WREG Memphis.
A ground equipment vehicle struck a Southwest Airlines aircraft during passenger boarding at Memphis International Airport (MEM) on June 21, 2026, forcing the carrier to remove the jet from service for safety inspections.
The incident resulted in no reported injuries among passengers or crew. According to reporting by Fox News Digital, travelers on Flight 4013 were accommodated on an alternate aircraft and reached their destination approximately four hours behind schedule.
Ramp incident and operational recovery
The collision occurred while passengers were actively boarding the aircraft. A Southwest Airlines spokesperson confirmed to Fox News Digital that a ground vehicle contacted the jet, prompting the airline to immediately pull the aircraft from the active schedule to undergo mandatory safety evaluations.
The Memphis Shelby County Airport Authority acknowledged the event, describing it in a statement as an isolated incident at the Tennessee facility. Following the collision, Southwest arranged for a replacement aircraft to complete the flight.
Reports indicate a discrepancy regarding the flight’s final destination. While a company representative told Fox News Digital the replacement flight was bound for Dallas, the airline’s website showed Flight 4013 continuing service to Harry Reid International Airport (LAS) in Las Vegas. The delayed flight ultimately arrived at approximately 5:30 p.m. local time, well past its original 1:50 p.m. scheduled arrival.
Safety investigations and industry context
Southwest Airlines stated that the collision will be reviewed through its internal Safety Management System. The carrier emphasized in a statement that customer and employee safety remains its highest priority. The Federal Aviation Administration (FAA) routinely monitors and may independently investigate ramp collisions involving commercial aircraft and ground support equipment.
Ground safety remains a persistent operational challenge at major commercial airports. Collisions involving baggage carts, catering trucks, and pushback tractors frequently result in costly aircraft damage and significant schedule disruptions, even when no injuries occur.
AirPro News analysis
We note that this ramp incident comes during a period of significant operational transition for Southwest Airlines. In 2026, the carrier is executing a major strategy reset, which includes the elimination of its legacy open-seating policy and the reduction of 11 international routes. While ground equipment collisions are generally isolated events managed by local station operations, any aircraft taken out of service out of base places immediate pressure on fleet utilization. The swift deployment of a replacement aircraft at MEM indicates the airline maintained sufficient operational slack to recover the flight, albeit with a four-hour delay.

NTSB Warns First Responders on Ballistic Parachute Hazards
NTSB Safety Alert SA-102 warns first responders that undeployed BPRS rockets on downed aircraft can fire at any time.

The National Transportation Safety Board (NTSB) is urging first responders to exercise extreme caution around downed aircraft equipped with ballistic parachute recovery systems (BPRS), warning that undeployed rocket mechanisms pose a severe risk of injury or death during rescue operations.
Following the issuance of Safety Alert SA-102 on January 20, 2026, the NTSB released a supplementary educational video on June 18, 2026, to amplify its safety campaign. The agency noted that while systems like the Cirrus Airframe Parachute System (CAPS) are designed to save lives in flight, “they pose a hazard to first responders at an accident site if the rocket did not activate before or during ground impact.”
Hidden hazards in the wreckage
First responders frequently need to extricate occupants from deformed fuselages following an aviation accident. The NTSB warned that the activation cable running along the airframe of a BPRS-equipped aircraft may be under tension and near its breaking point due to crash damage. Any sudden movement or structural cutting could inadvertently trigger the solid-propellant rocket.
If you must cut through the fuselage to free an occupant, avoid cutting the activation cable of the BPRS. If you need to cut the cable, be aware that this could activate the rocket.
The agency explicitly advised emergency personnel to contact the NTSB before attempting to disable any undeployed parachute systems, as the rocket can fire at any time if the system is compromised.
Historical precedent and emergency protocols
The safety alert cited three specific accident investigations where undeployed BPRS rockets created immediate hazards for ground personnel.
On February 16, 2016, an Evolution Revo crashed near Buckeye, Arizona. First responders operated around the wreckage for an hour before a Federal Aviation Administration (FAA) inspector alerted them to the active rocket hazard. On March 28, 2021, a Cirrus SR22 GTS crashed near Marana, Arizona. The pilot attempted an in-flight deployment that malfunctioned, leaving the rocket potentially active on the ground. On March 20, 2025, a Cirrus SR22 crashed near LaFayette, Georgia. In that accident, the BPRS rocket activated several minutes after the crash while emergency crews were positioned near the burning aircraft.
To mitigate these risks, the NTSB mandates that first responders immediately contact its 24/7 Response Operations Center at 844-373-9922 upon identifying a BPRS at an accident site.
AirPro News analysis
We note that as manufacturers like Cirrus Aircraft and BRS Aerospace continue to popularize whole-airframe parachutes, the intersection of aviation safety and local emergency response becomes increasingly complex. Local fire and rescue departments are typically the first to arrive at general aviation accident sites, yet they may lack specialized training on aircraft-specific ballistic hazards. The NTSB’s ongoing educational campaign, culminating in the June 2026 video release, underscores a critical gap in cross-disciplinary safety protocols that the aviation industry must actively help close to protect ground personnel.

Ubisoft Co-Founder Claude Guillemot Killed in France Plane Crash
Claude Guillemot, Ubisoft co-founder and EVP of Operations, died June 19 in a Cessna 421 crash near La Baule, France.

This is a developing story. Information may change as official details are released.
This article summarizes reporting by AP News by Angela Charlton, with additional corporate statements reported by Forbes.
Claude Guillemot, a co-founder of the global video game publisher Ubisoft Entertainment SA, and an unnamed flight instructor were killed on June 19, 2026, when their twin-engine Cessna 421 crashed during final approach to La Baule-Escoublac Airports in western France.
The 69-year-old executive served as Ubisoft’s Executive Vice President of Operations and Chairman of Guillemot Corporation SA. According to reporting by AP News, the aircraft was traveling from Rennes to La Baule for a weekend aviation gathering when it went down in a field near the airport and caught fire.
Flight and investigation details
The flight originated in Rennes on Friday evening. Local authorities confirmed two fatalities at the scene, identified as Guillemot and the flight instructor. Guillemot owned the Cessna 421 and was a licensed, experienced pilot. He was reportedly traveling to the Atlantic coast to participate in a private aviation event expected to draw over a hundred aircraft.
The Bureau d’Enquêtes et d’Analyses pour la Sécurité de l’Aviation Civile (BEA), alongside French judicial authorities, has initiated an investigation into the accident. The official cause of the crash has not been determined. Because both occupants were licensed pilots, investigators have not yet confirmed whether Guillemot or the instructor was at the controls at the time of the accident.
Ubisoft confirms executive death
Guillemot was one of five brothers who founded the video game publisher in 1986. The company has since grown into a major international developer, known for highly successful franchises including Assassin’s Creed. On June 20, 2026, Ubisoft released an official statement confirming the loss of its co-founder.
“Ubisoft was deeply saddened to learn of the death of Claude Guillemot, co-founder of the group and chairman of Guillemot Corp., in an accident. Our thoughts are with his family and loved ones during this difficult time. No further statements will be made at this time.”
AirPro News analysis
The loss of a founding executive and operational leader presents an immediate transition requirement for Ubisoft and Guillemot Corporation. While corporate succession plans have not been publicly detailed following the accident, the sudden departure of a key figure who has been with the company since its 1986 inception will require the board to stabilize operational oversight. We expect the BEA investigation to follow standard protocols for general aviation accidents, focusing on weather conditions, aircraft maintenance records, and pilot inputs during the critical final approach phase.
