WASHINGTON: The National Transportation Safety Board issued an urgent safety recommendation Wednesday to address the possibility of smoke entering the cockpit or cabin of Boeing 737 MAX airplanes equipped with CFM International LEAP-1B engines.
The NTSB also recommended evaluating the potential for the same issue with LEAP-1A and LEAP-1C engines, which are used on some Airbus A320neo variants and COMAC’s Chinese-made C919 jets.
The recommendation comes after two incidents involving Southwest Airlines Boeing 737 MAX jets that experienced bird strikes in 2023. The NTSB wants the Federal Aviation Administration to ensure that operators inform flight crews of airplanes equipped with the affected engines.
Southwest said it is reviewing the recommendations and that it has mitigation procedures currently in place. Southwest notified its flight crews about the effects of certain bird strikes following two events that occurred in 2023, reiterating the importance of following established safety procedures.
CFM, the world’s largest engine maker by units sold, is co-owned by GE Aerospace and Safran.
The NTSB said it was “critical to ensure that pilots who fly airplanes equipped with CFM International LEAP-1B engines are fully aware of the potential for smoke in the cockpit if the load reduction device is activated during a critical phase of flight (takeoff or landing).”
The FAA and Boeing both said they agreed with the NTSB recommendations, and the planemaker alerted operators that smoke could enter the flight deck following the activation of the Load Reduction Device (LRD) in the engines, as a result of a bird strike.
“We advised operators to evaluate their procedures and crew training to ensure they address this potential issue,” the FAA said. “When the engine manufacturer develops a permanent mitigation, we will require operators to implement it within an appropriate timeframe.”
Boeing said that CFM and Boeing “have been working on a software design update.” The NTSB wants the update to be required on all 737 MAX planes once completed.
GE, Airbus and COMAC did not immediately respond to requests for comment
The NTSB asked the European Union Aviation Safety Agency and the Civil Aviation Administration of China to determine if other variants of the CFM LEAP engine are also susceptible to smoke in the cabin or cockpit when an LRD activates. EASA did not immediately respond to requests for comment.
In November, the FAA said it would not require immediate action after convening a review board to consider concerns about Boeing 737 MAX engines after two bird strike incidents involving the CFM LEAP-1B.
The FAA had been considering recommendations for new takeoff procedures to close the airflow to one or both engines to address the potential impact of a bird strike and prevent smoke from entering the cockpit.
In 2024, the NTSB opened an investigation into the Southwest left engine bird strike and subsequent smoke in cockpit event that occurred near New Orleans in December 2023.
The other incident occurred in a Southwest March 2023 flight that had departed Havana and in which a bird strike led to smoke filling the passenger cabin.
In February 2024, Boeing published a bulletin to inform flight crews of potential flight deck and cabin effects associated with severe engine damage.

UPDATE 2-Walk for peace: Buddhist monks arrive in Washington after 2,300-mile journey
- Monks started in Texas, walked through nine states
- Walkers trod daily through frigid winter weather
WASHINGTON: Draped in burnt-orange robes, two dozen Buddhist monks arrived in Washington, D.C., on Tuesday on a 2,300-mile “Walk for Peace,” a self-described spiritual journey across nine states that has been cheered on by crowds of thousands. “People want this,” said Joan Donoghue, 59, from Silver Spring, Maryland, who had come out with four of her friends on Tuesday to see the monks. “I went on Sunday in Virginia and I waited outside for a long time and I talked to so many people and they all said the same thing: that our country needs this. We feel divided and people want more kindness and more compassion and more peace.”
The monks began their walk in Texas more than three months ago, at times braving frigid winter temperatures, sometimes with bare feet, to raise “awareness of peace, loving kindness, and compassion across America and the world.” The marchers continued on despite a powerful winter storm that spread a paralyzing mix of heavy snow, sleet and freezing rain from the Ohio Valley and mid-South to New England, compounded by bitter, Arctic cold gripping much of the US Accompanied by Aloka, a rescue dog from India who has gained a following on social media as “the Peace Dog,” their journey comes at a time of growing tensions in the US President Donald Trump’s tough immigration policy has seen surges of immigration agents and National Guard troops deployed in some cities, with both American citizens and immigrants killed by federal agents.
“We walk not to protest, but to awaken the peace that already lives within each of us,” said Bhikkhu Pannakara, spiritual leader of the Walk for Peace. “The Walk for Peace is a simple yet meaningful reminder that unity and kindness begin within each of us and can radiate outward to families, communities, and society as a whole.”
They will spend Tuesday and Wednesday in Washington and end their journey in nearby Annapolis, Maryland on Thursday.
The walk has garnered support from millions of people on social media, with many sharing messages of support for the monks. Supporters have braved snow and rain to meet and offer flowers to the monks as they passed through their cities. In Washington, hundreds of people came out to see the monks as they walked along a road informally known as Embassy Row because of the high number of embassies and diplomatic residences.
Coleman O’Donoghue, 62, of Washington, caught the attention of many of those onlookers as he carried a large flag with the peace symbol on a sea of blue. Tuesday was the fourth time he and his wife, Bonnie, had seen the monks.
“They are beautiful distraction from the chaos that is taking place in the city, the country and in the world right now,” O’Donoghue said. “It gives everyone a second to pause and think about something that is not as stressful as what the chaos is creating.”
While they waited hours just to see the monks for less than a minute, many of the spectators said the camaraderie and good energy made the experience worthwhile.
Julie Segor, 58, of Washington, made friends with a couple she met while waiting. Carl, 61, and Christine Varner, 65, of Maryland, pooled their flowers and fruit with her to give to the monks as they passed.
“It was a shared common interest to see the monks on the peace walk and give them some fruit and flowers,” Christine said.
During their stop in North Carolina, the state’s governor, Josh Stein, thanked the monks for bringing hope to millions with their message of peace, equality, justice and compassion.
“You are inspiring people at a time when so many are in need of inspiration,” Stein said. The Walk for Peace has made stops in Texas, Louisiana, Mississippi, Alabama, Georgia, South Carolina, North Carolina and Virginia. The monks met with spiritual and other leaders after arriving in Washington. They also held an interfaith ceremony at the National Cathedral.
During the ceremony at the cathedral, Kimberly Bassett, the District of Columbia’s secretary of state, presented the monks with a proclamation honoring them on behalf of the Washington Mayor Muriel Bowser.
“Today may mark the end of a 2,300-mile walk but it is not the end of our journey for peace. Your pilgrimage has brought people together across cities, states and communities,” Bassett said.
Although the walk has been positive, it has not been without obstacles. While walking through Dayton, Texas, a truck struck the monks’ escort vehicle, injuring several people, according to local media. Two monks sustained serious injuries and one had his leg amputated.
Despite the accident, the group continued to trek across the US to honor not only their original message of peace but also their brothers.
