Boeing is already working on the recommendations from the National Transportation Safety Board (NTSB) after the regulator's investigations revealed that the U.S. jet maker can develop a redesign for the 737 New Generation (NG) aircraft.

According to CNN, the NTSB investigated an incident last year wherein one passenger was killed onboard a Boeing 737 NG jet after a blade was broken and part of the engine's cover hit the jet's side area. The board said on Tuesday that a redesign will prevent future incidents.

The NTSB went on to recommend that all 737 NG planes should receive whatever fix Boeing develops to ensure that no accidents involving fan blades will take place shortly.

Boeing said it is already developing a patch about the regulatory board's recommendations on the planes in question. "Our common goal is to help prevent similar events from happening in the future," the American aviation giant said.

So far, Boeing has officially delivered around 6,700 737 NG jets to airliners around the world. However, no new orders were accepted since the 737 Max aircraft started gaining popularity among airline operators.

If the company does adhere to the NTSB's recommendations, it could be concluded that the jet maker has to apply fixes on all delivered planes, regardless of the location of the jets or which airliner has fleets of the said model.

CNBC noted that Boeing has committed to integrating "enhancements" on fan cowls in the model to further enhance the jet's ability to prevent the possibility of fans breaking. The company also said it will work closely with the Federal Aviation Administration (FAA) regarding the matter.

The death of a passenger in April 2018 onboard a 737 NG aircraft is the first in almost 10 years, and is also completely unrelated to the 737 Max model's troubles since it was grounded in March.

Despite its multiple problems with the grounded planes, the company bagged up to $6 billion in deals at the Dubai Airshow. According to The Guardian, among the carriers that inked deals with Boeing is Kazakhstan's Air Astana, which order eight jets for its subsidiary FlyArystan.

During the airshow, Air Astana reiterated that it is confident in Boeing's abilities to the problems that the 737 Max aircraft is faced with. The jets were grounded after two crashes took the lives of 346 people within roughly five months.

Aside from the deal with Air Astana, Boeing also snagged a blockbuster deal with British Airways in June for 200 jets. The deal has yet to be finalized as the European carrier has to implement changes to its subsidiary firms that currently operate rival Airbus fleets.
