NTSB issues Urgent warning for Boeing 737 Max engines after bird strikes

The National Transport Safety Council (NTSB) issued an urgent safety recommendation on Wednesday to amend jet engines Boeing 737 maximum Aircraft to prevent smoke from entering the cockpit or cabin in certain scenarios.

The warning comes after two incidents Southern West Airlines CFM International Leap-1B aircraft that suffered from bird strikes in 2023.

NTSB said that these CFM engines have a safety feature, called a pregnancy reduction device, which can unintentionally damage the engines of the engines as soon as they are activated after the bird’s blow. The damage can lead to the formation of smoke from the hot oil that was launched in the engine and the ventilation system and ultimately the cabin of the cockpit or passengers.

NTSB achieved an accident in December 2023, which included a southwest aircraft plane that struck a bird while taking off from New Orleans. The plane quickly landed after “white smoke” filled the cockpit and was so thick that the captain said it was difficult to see the meter plate.

The southwest adds the “strong” cockpit alert to detect the risk of the runway

Another accident occurred nine months before similar damage to the engine on another southwest of Havana, Cuba, after the birds were taken in a engine shortly after take off, which fill the compact smoke.

Either way, flights fell safely, and no one was hurt.

NTSB has also recommended assessing the possibility of the same problem with the CFM Leap-1A and Leap-1C engines, which are used on some Airbus A320neo aircraft and C919 jets made by the commercial aircraft company in China.

CFM is owned by GE Aerospace and Safran.

Boeing shares a chip after the crash

the Federal Aviation Administration Boeing said they both agreed on NTSB recommendations and have already warned airlines and pilots of the problem.

“We have advised operators to evaluate their procedures and train the crew to ensure the treatment of this potential issue,” the Federal Aviation Administration said. “When the engine manufacturer develops a permanent relief, we will ask the operators to implement it within a suitable time frame.”
