On June 28, the crew of a United Airlines Boeing 737 MAX 9 (Registration N37516) flying from Fort Lauderdale saw an engine fire warning after landing at Newark Liberty International Airport (EWR). The plane was carrying 179 passengers and five crew members on a routine short hop.
Because the plane taxied to the terminal, the hearth warning light on the left engine went off, forcing the pilots to shut down the engine and use an onboard firefighting system. Not one of the occupants of the plane were injured. The National Transportation Safety Board (NTSB) is investigating the incident with the assistance of United Airlines and airport officials.
The two.5-hour journey operated as UA2376 from Fort Lauderdale (FLL) to EWR was uneventful until the aircraft landed and left the runway to proceed to the terminal. The crew was prompted to shut down the left engine as a consequence of fire immediately. After following the emergency procedure, the outside of the plane was examined by the technical staff.
There was no visible fire or smoke from the engine. The aircraft was towed to the gate, where the upkeep crew further examined the aircraft. The crew found evidence of a fuel leak and warmth damage on one among the CFM International LEAP 1-B engines.

The Federal Aviation Administration (FAA) reported that every one passengers and crew exited the aircraft in line with normal procedures with none further incident. The FAA said the plane landed after the flight crew activated the engine fire extinguishers as a precautionary measure given the left engine fire warning.
Based on the preliminary evidence, the NTSB reported that the majority of the warmth damage is found on the engine cases and external surfaces. Until the aircraft is faraway from service and the engine is thoroughly inspected, it will be difficult to discover the extent of injury on the within.
The 4-year-old aircraft involved within the incident, N37516 was delivered to United Airlines on December thirtieth, 2020.
The LEAP engine
The CFM International LEAP (Leading Edge Aviation Propulsion) is a high-bypass ratio turbofan engine that powers the Boeing 737 MAX family of aircraft. CFM International is a partnership between General Electric in the US and Safran Aerospace in France. The -1B model of the engine has a thrust range of 23,000 – 28,000 Ibf (100-120 kN), with a maximum takeoff thrust of 29,320 If (130 kN), designed for the MAX.
CFM International claims that LEAP operators will see at the very least a 15% improvement in fuel consumption in comparison with the previous engines. Boeing claims the 737 MAX provides 15-20% greater fuel efficiency than its predecessors. A big contribution to fuel efficiency goes to the ultra-efficient LEAP engines.

The LEAP-1B has a bypass ratio of 9:1, which makes it able to moving a big air mass from the inlet to the exit at a much lower overspeed. This leads to greater propulsive efficiency and lower specific fuel consumption (sfc).
