This image taken Feb. 22, 2021, shows the damage to the number 2 engine of United Airlines flight 328, a Boeing 777-200, following an engine failure incident Saturday. The NTSB is investigating the incident. United Airlines flight 328 experienced a right engine failure after takeoff from Denver International Airport Feb. 20, 2021. The airplane returned safely to Denver; none of the 229 passengers or 10 crew members were injured. (NTSB)

(AP) – Microscopic examination supports early suspicions that wear and tear caused a fan blade to snap inside one engine of a United Airlines plane that made an emergency landing shortly after takeoff last month in Denver, federal safety investigators said Friday.

The National Transportation Safety Board said the blade found “multiple fatigue fracture origins” on the inside surface of the hollow fan blade. The board said “multiple” secondary cracks were found, and that the examination is continuing.

The broken blade on the Pratt & Whitney engine had been used on 2,979 flights since its last inspection in 2016, the NTSB said. At the time, similar blades were required to be inspected every 6,500 flights. The NTSB believes the failed blade then sheared off part of an adjacent fan blade.

After the Feb. 20 incident, Pratt & Whitney called for inspections every 1,000 flights, followed by a Federal Aviation Administration order that they be inspected for cracks before their next flight.

The particular Pratt & Whitney engines involved are found on fewer than 100 Boeing 777 jets currently in use. They’re also on several dozen other planes that have been parked because of weak passenger traffic during the pandemic. The affected planes are all used by United Airlines and by carriers in Japan and South Korea.

The engine failure occurred four minutes after the Boeing 777 took off, bound for Hawaii. Debris from the engine and its housing rained down on suburban neighborhoods. The NTSB said the pilots had just increased power to the two engines when a loud bang was captured on the cockpit voice recorder.

Information from the plane’s data recorder indicates that the engine shut down automatically and triggered a fire warning. The United pilots declared an emergency and returned to Denver International Airport with one working engine and landed safely. No injuries were reported on the plane or on the ground.

Florida deaths rise to 47 amid struggle to recover from Ian

Rescuers have evacuated stunned survivors cut off by Hurricane Ian on Florida's largest barrier island, and the state's death toll has risen sharply amid recovery efforts. Hundreds of thousands of people are still sweltering without power in the state, days after Ian's rampage from Florida to the Carolinas. Florida now has 47 confirmed deaths. Ian was one of the strongest U.S. hurricanes on record when the Category 4 monster smashed ashore at midweek. Many storm victims were left isolated with limited cellphone service and lacking basic amenities like water and power. As of Sunday morning, nearly 850,000 customers in Florida were still without electricity.
