The National Transportation Safety Board (NTSB) has sanctioned Boeing, criticizing the company for leaking sensitive details from the ongoing investigation into a January incident involving a 737 MAX 9 door plug blowout. 

This move comes just weeks after Boeing faced scrutiny for its interactions with the FAA prior to the 737 MAX fatalities.

According to the NTSB, Boeing violated its agreement as a party to the investigation by sharing confidential information with the media during a press briefing on June 25th. This agreement prohibits disclosing details not yet verified by the NTSB and offering opinions on potential causes.

Sanctions Imposed

For this breach of trust, the NTSB has imposed several sanctions on Boeing. The company will no longer receive updates on the investigation’s progress, even though it retains NTSB’s official party status. 

Additionally, Boeing is required to appear at a hearing on August 6th and 7th in Washington D.C. However, unlike other participants, they will be barred from asking questions.

The NTSB emphasized their primary objective of determining the root cause of the incident, not assigning blame to any individual. This stands in contrast to Boeing’s alleged portrayal of the investigation during their media briefing, which the NTSB claims focused on finding a single culprit.

This highlights the ongoing challenges surrounding the B737 MAX program and raises questions about Boeing’s commitment to transparency during safety investigations. The NTSB’s decision to collaborate with the Department of Justice’s (DOJ) Fraud Division further underscores the seriousness of the situation.

The National Transportation Safety Board (NTSB) recently published a conclusive report on Delta Air Lines Flight 211, which encountered an anomalous autopilot issue during its flight in July 2022.

In 2022, Delta Air Lines Flight 211 was a return leg from Prague (PRG) to New York (JFK) before the flight number was reassigned to Delta’s South Africa services.

The flight had 221 passengers and 12 crew members onboard and departed from Prague at around 14:00 CEST. The journey between the two cities took around 9 hours and was operated by Delta’s 30-year-old Boeing 767-300 with registration number N181DN.

During Delta Air Lines Flight 211, cabin crew members reported flooding in the mid-cabin and forward-left lavatories while passing over southern Greenland.

Although an out-of-service aircraft is usually not an emergency, as the flight progressed, the flight deck crew noticed that the aircraft’s autopilot had disconnected and that there were roll control issues.

When the team attempted to fix the problem, they found that they couldn’t reconnect any of the aircraft’s three autopilots, and the aircraft was gradually drifting right.

Delta 767 Autopilot Incident

During Delta Air Lines Flight 211 in 2022, which flew from Prague to New York, issues arose when flooding was reported by cabin crew members in the mid-cabin and forward-left lavatories. Additionally, the autopilot disconnected, and there were concerns with the aircraft’s roll control.

The flight crew declared an emergency and began diverting to Gander Airport while attempting to regain control of the aircraft. They felt a slight jolt as they descended through 12,000 ft and were able to regain control of the flight. The emergency was cancelled, and the aircraft landed an hour later than scheduled at JFK. After landing, the aircraft was sent to Delta Air Line’s TechOps for repairs.

Repairs included the autopilot and roll control inspections, the grey water drain masts replacement, and a seal close to the aileron centring and trim mechanism. The aircraft was cleared for service on July 12th, reported SimpleFlying

NTSB Report

According to the NTSB’s report published on Friday, the limited flight controls and autopilot error on Delta Air Lines Flight 211 can be traced back to the faulty toilets.

Despite the older age of the aircraft, the report suggests that human error was the primary cause of the incident. Delta Air Lines’ maintenance, repair, and overhaul (MRO) personnel found that the forward and aft toilets’ drain mast heater circuit breakers had been left open during prior maintenance in June 2022.

The NTSB concluded that this led to the formation of ice in the forward drain mast, improper wastewater flow into the main landing gear wheel well, and ice formation on one or more aileron system components. Delta Air Lines replaced the elements and confirmed normal functioning during testing.

According to the US NTSB department, the Cirrus SR22 aircraft pilot’s high-speed turn from base leg to final resulted in overshooting the centerline and entering a parallel approach path, leading to a collision with a Swearingen Metroliner.

The accident occurred on May 12, 2021, at Colorado’s Centennial airport, causing substantial damage to both planes on different tower frequencies.

The pilot and passenger of the Cirrus survived after deploying its recovery parachute, and the Metroliner’s pilot landed safely.

The airport’s parallel runways, 17R and 17L were in use, with the Metroliner approaching 17L and the Cirrus flying downwind on a right-hand traffic pattern for 17R.

The Cirrus, under manual control, was flying at about 148kt during the base leg, although the recommended approach speed with flaps up was around 90-95kt.

Cirrus SR22 and Metroliner Collision

During the Cirrus SR22’s turn to final approach at Centennial Airport (APA) in Colorado. The aircraft collided with a Swearingen Metroliner after overshooting the centreline and straying into a parallel approach path.

The accident occurred on May 12, 2021, and both aircraft were significantly damaged. However, the Metroliner managed to land safely while the Cirrus deployed its recovery parachute.

The collision occurred halfway through the turn to final, on a heading of 146°, about 3.2nm north of the airport and at an altitude of about 735ft, causing a large section of the upper aft fuselage to be torn out.

The Key Lime Air aircraft, which was being positioned from Salida, landed safely despite the damage. According to the Metroliner pilot’s statement to investigators, he initially checked the engine controls, thinking that one of the powerplants had failed after hearing a “tremendous explosion.”

Despite the damage, the Cirrus activated its parachute system and landed about 3nm north of the airport. Furthermore, the collision took place in good daylight weather conditions.

NTSB Report

The US National Transportation Safety Board (NTSB) has found that the Cirrus pilot’s decision led to the crash. The pilot flew at a higher speed than the recommended approach speed, resulting in a larger turn radius and an overshoot of the 17R approach.

The aircraft deviated into the 17L approach path, and its course would have taken it further left of the final approach course for 17L. Then it had not collided with the Metroliner, according to the investigation.

However, the inquiry also revealed that the two aircraft were communicating with different tower controllers. Both were on separate radio frequencies while approaching the airport.

The controller handling the Cirrus cleared it to land on 17R and provided traffic advisories to the pilot. However, the Metroliner’s controller, who also had landing clearance, did not give the pilot an advisory about the Cirrus’s location.

The inquiry noted that if the controller had issued an advisory. The Metroliner pilot might have identified the conflict and maneuvered the airplane to avoid the collision.

Both pilots had been advised of the presence of another aircraft. A Cessna, which had been in the traffic pattern for 17R ahead of the Cirrus. It revealed that Cirrus’s avionics system issued a traffic alert that remained on until the collision 36 seconds later.
