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.

Small Plane Crashes into North Phoenix Neighborhood; Three Injured

A single-engine aircraft crashed into a residential neighborhood in North Phoenix on the morning of Wednesday, March 4, 2026, injuring three people and damaging two homes. According to reporting by 12News, the incident occurred near the intersection of Deer Valley and Cave Creek roads as the plane attempted to return to the nearby airport.

Emergency responders arrived at the scene in the 2000 block of East Parkside Lane shortly after 7:30 a.m. MST. The aircraft, identified by authorities as a Piper PA-28, struck the roof of one residence before coming to rest in the backyard of a neighboring property. While the crash caused significant structural damage and a fuel leak, officials have confirmed there were no fatalities.

Incident Timeline and Flight Details

The crash occurred during the morning rush hour, a time when many residents were still at home. Preliminary information cited by local outlets indicates that the aircraft had recently departed from Deer Valley Airport (DVT), one of the busiest general aviation airports in the world.

Attempted Return to Airport

According to the Federal Aviation Administration (FAA), the pilot appeared to be attempting a return to the airfield shortly after takeoff. While the National Transportation Safety Board (NTSB) has not yet determined a probable cause, an immediate return to the airport often suggests a mechanical anomaly or onboard emergency. The Piper PA-28 is a common trainer aircraft, and reports confirm that a flight instructor and a student pilot were the two occupants on board.

Injuries and Property Damage

The Phoenix Fire Department responded rapidly to the scene to manage potential fire hazards and treat the victims. Three individuals were transported to local hospitals.

Occupants and Residents

Both the flight instructor and the student pilot survived the impact. They were transported in stable condition with injuries described by responders as cuts and burns. On the ground, one resident, a homeowner, was also injured. Reports suggest the resident was either inside the home or in the backyard at the moment of impact; they were hospitalized as a precaution.

Structural Impact and Hazmat Response

The collision caused distinct damage to two separate properties. The plane clipped the roof line of the first home before crashing into the second home’s yard. The impact ruptured the aircraft’s fuel tanks, causing fuel to leak into the attic of one of the structures. Hazmat crews were deployed to contain the spill and prevent environmental contamination or fire.

“Situations like this when you do have multiple residences involved… it is a miracle that no one was [seriously] injured.”

— Phoenix Fire Department spokesperson

Investigation and Safety Context

Federal investigators from the NTSB and FAA are currently on-site to document the wreckage and determine the sequence of events leading to the crash. The investigation will likely focus on engine performance, pilot communications with air traffic control, and weather conditions at the time of the flight.

Deer Valley Airport Operations

Deer Valley Airport handles over 400,000 flight movements annually, heavily driven by flight training operations. The surrounding area is densely populated, creating a complex interface between urban residential zones and aviation activities. While crashes in these neighborhoods are statistically rare given the volume of traffic, this incident follows a pattern of occasional emergency landings in the open lots and streets surrounding the airport.

AirPro News Analysis

Training density and urban planning: The survival of all involved in this crash highlights the crashworthiness of modern general aviation airframes, but it also underscores the risks inherent in the “urban interface” of busy training airports. Deer Valley Airport was once surrounded by open desert, but Phoenix’s rapid northward expansion has encircled the facility with residential housing.

When training aircraft suffer power loss on takeoff, the most critical phase of flight, pilots have very few options if they cannot glide back to the runway. In this instance, the pilot’s attempt to turn back, a maneuver known to be high-risk at low altitudes, suggests the situation was critical. The lack of fatalities is indeed fortunate, but this event will likely renew local discussions regarding flight path zoning and safety buffers in North Phoenix.

Singapore Airlines A350 Clips Spirit Airlines Jet at Newark Liberty International Airport

A Singapore Airlines Airbus A350-900 preparing for the world’s longest commercial flight collided with a parked Spirit Airlines aircraft at Newark Liberty International Airport (EWR) on the morning of March 3, 2026. The incident, which occurred during pushback near Terminal B, resulted in damage to both aircraft but caused no injuries to passengers or crew.

According to reporting by ABC7NY, the collision took place as the Singapore Airlines jet was maneuvering away from the gate. Its right wingtip made contact with the tail of a stationary Spirit Airlines plane. While the Spirit flight was subsequently cancelled due to the damage, the Singapore Airlines aircraft was inspected and eventually cleared to continue its journey.

Incident Details and Timeline

The collision occurred at approximately 10:20 AM EST. Aviation data indicates that the Singapore Airlines aircraft, operating as Flight SQ21, was pushing back for its scheduled departure to Singapore (SIN). The Spirit Airlines aircraft, an Airbus A321neo operating as Flight NK992 to Orlando (MCO), was parked and undergoing de-icing at the time of impact.

Audio recordings from LiveATC captured the immediate reaction from the cockpit of the Singapore Airlines jet. The pilot reported the incident to the tower shortly after the impact.

“Uh, right wing may have touched the Spirit behind us.”

Following the collision, the Singapore Airlines crew requested a tow back to the gate to assess the situation. Emergency services and ground crews responded to the scene at Terminal B, an area of the airport typically controlled by airline ramp personnel rather than Air Traffic Control.

Aircraft and Operational Impact

Flight SQ21: The World’s Longest Flight

The Singapore Airlines aircraft involved was identified as an Airbus A350-900, registration 9V-SGA. This specific aircraft is configured for the carrier’s ultra-long-range missions. Flight SQ21 covers approximately 9,500 miles and can take up to 19 hours. Despite the collision, engineers inspected the wing structure and deemed the aircraft safe for flight. It departed later in the day to complete its journey to Singapore.

Spirit Airlines Flight NK992

The Spirit Airlines aircraft, identified as N720NK, sustained damage to its tail section. Unlike the Singapore Airlines flight, the Spirit flight was unable to proceed. The flight was cancelled, and passengers were deplaned and rebooked on alternate flights to Orlando.

Official Statements and Investigation

The Federal Aviation Administration (FAA) has confirmed it is investigating the incident. In a statement referenced by reports, the agency noted that the collision occurred in a “non-movement area,” referring to the ramp sections where aircraft are guided by wing walkers and tug drivers rather than direct tower control.

Spirit Airlines confirmed that their aircraft was stationary during the event. “Our aircraft was parked and undergoing de-icing when the wing clip occurred,” the airline stated, emphasizing that their priority was re-accommodating affected guests.

Singapore Airlines acknowledged the incident, stating that their engineering team carried out a full inspection of the Airbus A350-900 before clearing it for departure.

Ramp Congestion at Newark

Newark Liberty International Airport is notorious for its tight ramp areas and high congestion, particularly during peak morning departure banks. “Wing clip” incidents, while minor in terms of passenger safety, highlight the precision required during pushback operations. In confined spaces like the Terminal B ramp, the margin for error is slim. The fact that the Spirit aircraft was undergoing de-icing adds another layer of complexity to the ground environment, as de-icing trucks and personnel reduce the available maneuvering space for passing aircraft.

While the damage to the Singapore Airlines jet was evidently superficial enough to allow it to fly a 19-hour transpacific route, the grounding of the Spirit jet suggests the tail section took the brunt of the force. Structural repairs to the tail of an A321neo can be costly and time-consuming, potentially removing the airframe from service for several days or weeks.

Frequently Asked Questions

Was anyone injured in the collision?
No. There were no reported injuries among the passengers or crew on either the Singapore Airlines or Spirit Airlines aircraft.

Did the Singapore Airlines flight cancel?
No. Although it was delayed for inspection, Flight SQ21 was cleared by engineers and departed for Singapore later the same day.

What caused the collision?
The incident occurred during pushback. While an official cause has not been determined by the FAA investigation, these incidents are typically attributed to misjudgments regarding clearance between wingtips and obstacles in tight ramp areas.
