Universal Hydrogen receives approval from FAA to begin flight tests

Universal Hydrogen Co., whose mission is to make hydrogen aviation a near-term reality, announced it was granted a special airworthiness certificate in the experimental category by the Federal Aviation Administration (FAA) to proceed with the first flight of its hydrogen-powered regional aircraft. The company also released video footage of successful first taxi tests of the aircraft, designed to evaluate ground handling qualities and the performance of the fuel-cell electric powertrain at low power settings and airspeeds.

The Dash 8-300 flying testbed has a megawatt-class hydrogen fuel cell powertrain installed in one of its nacelles. The powertrain is in a configuration that closely resembles the company’s first product—a conversion kit for ATR 72-600 regional airliners—which is expected to be certified and in commercial passenger service starting in 2025. Notably, Universal Hydrogen’s powertrain does not utilize a hybrid battery architecture—a major innovation—with all of the power transmitted directly from the fuel cells to the electric motor, significantly decreasing weight and lifecycle cost.

The FAA approval clears the way for the first flight of the Dash 8-300 flying testbed which will take place at Grant County International Airport in Moses Lake, Washington. The aircraft will be by far the largest hydrogen fuel cell-powered airplane to take to the skies, and second as a hydrogen-powered aircraft only to the Soviet flight test in 1988 of a Tupolev Tu-155 airliner with one of its jet engines converted to burn hydrogen.

Universal Hydrogen unveiled in December 2022 first operational tests of its modular hydrogen delivery system at its engineering center in Toulouse, France. Those tests demonstrated a pragmatic, near-term, and highly scalable approach to hydrogen delivery to airports and into aircraft using modular capsule technology. This eliminates the need for costly new infrastructure, with any airport capable of handling cargo being hydrogen-ready. It also eliminates transfer losses and significantly speeds up hydrogen fueling operations—both significant pain points for the zero-emissions fuel.

Air India Express Aircraft Engine Part Falls Outside Delhi Airport; DGCA Orders Probe

Air India Express flight skids off runway while landing at Kochi airport

The Directorate General of Civil Aviation (DGCA) has launched an inquiry following reports that metal fragments were discovered at Delhi’s Indira Gandhi International Airport after an Air India Express flight made an emergency landing on Monday evening.

The emergency landing was prompted by a detected engine fault, but fortunately, the landing was executed safely without any injuries to the passengers.

The situation began when crew members of the Air India Express flight reported an engine issue, leading to the emergency landing. The DGCA has confirmed that a thorough investigation is underway and has directed that the aircraft undergo a comprehensive safety inspection.

The discovery of metal debris outside the airport has raised concerns, prompting the DGCA to probe whether these fragments are linked to the aircraft involved in the emergency landing. Authorities are particularly focused on whether the metal pieces, which were found near the airport, originated from the same Air India Express flight that experienced engine trouble.

While preliminary assessments suggest that the debris could be a broken blade from an aircraft engine, the exact source remains unconfirmed. The airline has yet to verify if the metal fragments are from their aircraft.

The Delhi Police, working in conjunction with the DGCA, have initiated their own investigation to determine the origin of the metal pieces. A technical team is set to analyze whether the fragments are associated with the aircraft in question. As the investigation continues, a case has been filed with the airport authority to address the matter.
