Key Points

In a heated exchange, Rep. Steve Cohen asks Boeing CEO Dennis Muilenburg whether he is taking responsibility for the fallout from the 737 Max crashes.

Cohen asks if Muilenburg or anyone else at the company will be taking a pay cut because of 737 Max issues. Muilenburg says the board will make those decisions.

Boeing replaced the head of its commercial airplane unit Kevin McAllister earlier this month. He is the senior-most executive to leave in the wake of the catastrophes.

Boeing CEO Dennis Muilenburg was grilled about his salary on Wednesday, the second day of congressional hearings about the company’s 737 Max jets, which were involved in two fatal crashes.

Rep. Steve Cohen, D-Tenn., questioned in a heated exchange whether Muilenburg was taking responsibility for the fallout from the crashes, which killed 346 people in total. Cohen asked if anyone at the company had taken a pay cut amid the grounding of the 737 Max.

“You’re saying you’re not giving up any compensation at all,” Cohen asked Muilenburg. “You’re continuing to work and make $30 million a year after this horrific two accidents that caused all these people’s relatives to go, to disappear, to die.”

Muilenburg earned total compensation of just under $23.4 million for 2018, according to a Securities and Exchange Commission filing. He also cashed in delayed stock payouts from previous years, bringing his total actual compensation for the year to $30 million.

Boeing is not handing out executive bonuses this year, according to a company spokesperson.

When Muilenburg was asked directly if he would take a cut in pay, he said the company’s board makes those decisions.

“You’re not accountable then,” Cohen said. “You’re saying the board’s accountable.”

Boeing replaced the head of its commercial airplane unit Kevin McAllister earlier this month. He is the senior-most executive to leave in the wake of the catastrophes.

Muilenburg said during the questioning Wednesday by members of the House Committee on Transportation and Infrastructure that he has not offered to resign following the 737 Max crashes.

Rep. Peter DeFazio, D-Ore., who chairs the committee, also challenged Muilenburg on his compensation and the consequences he has faced after the two crashes.

“You are the CEO of the largest aircraft manufacturer in the world,” DeFazio said. “You’re earning a heck of a lot of money, and so far the consequence to you has been, oh, you’re not chairman of the board anymore.”

Muilenburg appeared before the Senate Commerce Committee on Tuesday.

Here is the full exchange between Cohen and Muilenburg:

Cohen: Is anybody at Boeing taking a cut or working for free to try to rectify this problem? Like the Japanese would do?

Muilenburg: Congressman, my board will conduct a comprehensive review …

Cohen: So you’re saying you’re not giving up any compensation at all? You’re continuing to work and make $30 million a year after this horrific two accidents that caused all these people’s relatives to go, to disappear, to die. You’re not taking a cut in pay at all?

Muilenburg: Again, our board will make those determinations.

Cohen: You’re not accountable then. You’re saying the board’s accountable.

The ADAPT ESD system has three CPU modules. The CPU (part number 323174-01) is a state-ofthe-art, high-performance CPU module. All three CPU modules process all 32 discrete inputs and 12 analog inputs. Each individual CPU module processes two speed inputs, for a total of six speed inputs. The CPU module features redundant Ethernet connections. The CPU receives trip logic configuration from the Bently Nevada Monitor Configuration software. The trip logic can have up to 500 logic steps. The input-to-output decision time is optimized to provide 2ms nominal logic processing time and 8ms relay toggle time in order to minimize the overall duration between detection of an emergency condition and successful shutdown. All embedded code on the CPU is capable of being upgraded without disassembly of the system.

ADAPT ESD Relay Module

There are three relay modules in each ESD system. Each Relay Module (part number 323073-01) has five relay contacts. Two of the relays are independent relays, driven by a corresponding CPU module. The remaining two relays are configurable as either independent or 2oo3 voted. When using a 2oo3 mechanical trip assembly, a typical installation would involve a series connection of one independent relay from each of the three relay modules. Each of the three CPUs would independently drive relays on each of the three relay cards. When two of the three CPUs drive for trip, the trip assembly would have the inputs it needs to actuate the safety mechanism. Alternately, 2oo3 relays can be implemented directly on the ESD system. The remaining fifth relay is a protection fault relay used to convey the overall health/status of the system. The ADAPT ESD system drives the protection fault relay to broadcast a condition has compromised the integrity of the system.

Networking Overview

The 3701/55 ADAPT ESD system supports fixed (static) IP addressing as well as DHCP. You can easily use the Bently Nevada Monitor Configuration software to set the system to any static IP address or set for DHCP. The system has 6 physical network interfaces in order to provide 2 interfaces per CPU module. The system should be configured so that each CPU module is connected to a single subnet through one of the available interfaces. For redundant communications, the second set of three interfaces can be utilized, and should be configured for a separate subnet.

Key Points

A helicopter crashed into the Hudson River off of Manhattan, killing all 6 people on board.

The victims included a Siemens executive, his wife and five children, visiting from Europe.

The helicopter appeared to be used for sightseeing tours, according to flight data.

Rescue workers and emergency personnel work at the scene of a helicopter crash on the Hudson River near lower Manhattan in New York, U.S., as seen from Newport, New Jersey, April 10, 2025.

A sightseeing helicopter crashed into the Hudson River off of Manhattan Thursday, killing all six people on board. It was the deadliest helicopter crash around New York City in years.

Agustin Escobar, the CEO of rail infrastructure at Siemens Mobility, his wife and three children, all visiting from Europe, and the pilot of the helicopter died in the crash.

“We are deeply saddened by the tragic helicopter crash in which Agustin Escobar and his family lost their lives,” Siemens said in a statement.

Four of the victims were pronounced dead at the scene and two more died after they were removed from the scene.

The cause of the crash is under investigation, officials said. The helicopter was operated by “New York Helicopters,” New York Police Commissioner Jessica Tisch said a press conference Thursday afternoon.

The helicopter tour company New York Helicopter didn’t immediately respond to request for comment. The company offers sightseeing tours and had one scheduled for 3 p.m. on Thursday, according to its website.

First responders walk along Pier 40, Thursday, April 10, 2025, in New York, across from where a helicopter went down in the Hudson River in Jersey City, N.J.

A witness’s video showed a helicopter plummeting to the river. Other video posted on social media showed a helicopter upside down in the Hudson River. An eyewitness told NBC New York that she saw the helicopter lose a propeller and that the aircraft’s nose pointed downward.

The helicopter was a Bell 206L-4 LongRanger, according to FlightRadar24, a flight-tracking site.

The flight path showed the helicopter taking off from a heliport on the southeastern tip of Manhattan, then flying up the Hudson River, getting up to an altitude of about 1,100 feet, and turning around near the George Washington Bridge, with last contact off of Hoboken, New Jersey, about 15 minutes after takeoff, FlightRadar24 data showed.

The helicopter’s flight records show it both taking off and landing from the Downtown Manhattan Heliport several times in the last few days. Such routes are common with sightseeing helicopter tours.

The National Transportation Safety Board said it will investigate the crash and that it is still gathering information. The Federal Aviation Administration didn’t immediately comment.

“Due to a helicopter crash in the Hudson River, in the vicinity of the West Side Highway and Spring Street, expect emergency vehicles and traffic delays in the surrounding areas,” the NYPD said in a post on X.

There have been several helicopter crashes around Manhattan over the years. In March 2018, a helicopter hired for a photoshoot crashed into the East River, killing five people on board, though the pilot survived.

In June 2019, a helicopter flying in heavy fog crashed into the top of a Manhattan office building, killing the pilot.

The AC 800PEC is the perfect way to unite the system design capabilities of ABB’s ControlIT with the control and simulation capabilities of MATLAB® / Simulink®. Quick implementation of complex control algorithms (e.g. model predictive control) reduces development cycles and costs. Furthermore, the system is open to future technologies.

Implementation of the AC 800PEC software on the three performance levels provides an exceptional range of control and communication functionality:

Level 1: System engineering (ControlIT) ABB’s ControlIT supports all 5 IEC61131-3 programming languages and uses ABB’s Control Builder as the programming tool. This is the level on which system engineers implement functions that do not require high-speed performance but demand quick and easy adaptation to a specific project. AC 800PEC controllers can also be fully integrated into ABB’s 800xA automation systems.

Level 2: Product & control development (MATLAB / Simulink™)

Fast closed-loop control applications are designed using MATLAB® / Simulink®. C-code is automatically generated and downloaded to the embedded device using Real-Time Workshop® from MathWorks®.

Typically, it is on this level that control developers will implement the control, the protection, the state machine and other functions.

Level 3: Communication & very fast logic (VHDL)

Extremely fast processes are programmed in VHDL. Protocols and some control logic requiring extremely short cycle times are implemented on this level. The standardized tasks are available as firmware modules and are not accessible to the application developers.

Modularity and connectivity for any size and performance

Scalability in size – from small and compact to large and modular

For any application size, the optimum hardware configuration is easily achieved: the processing power can either be centralized at one location with distributed logical I/O devices, or intelligent I/O devices can carry out specific tasks in the field to enhance performance and relieve the central processor.

Three system architectures provide scalability from small and compact to large and modular systems:

Compact

One processor module with integrated, fast I/O devices. This

configuration is ideally suited for:

− Smaller applications

− Limited-space applications

− Intelligent field devices, e.g. subsystems in distributed applications

Standard

One processor module with separate, fast logical I/O devices. This configuration is ideally suited for:

− Standard industrial applications with central processing

− Small applications with detached, fast I/O

Modular

One or several central processor modules with separate, fast, intelligent I/O and fast logical I/O devices. Full and trouble-free integration into higher-level plant control systems as well as future expansions and reconfigurations are easy thanks to the fully modular architecture.

Scalability in performance – you and your process define

what you need

Your process defines the required performance level. Several

pre-configured software packages are available for easy and

straightforward engineering:

− DCS (Distributed Control System)

− Processing cycle times down to 1 ms

− Use of slow I/O

− Programming in Control Builder

− PLC (Programmable Logic Controller)

− Processing cycle times down to 1 ms

− Use of fast and slow I/O

− Programming in Control Builder

− PAC (Programmable Automation Controller)

− Cycle times down to 100 μs

− Use of fast and slow I/O

− Programming in MATLAB/Simulink and Control Builder

Process interfaces for any speed The AC 800PEC provides two kinds of I/O – fast and slow. Whereas the fast I/O system covers read and write operations requiring less than 1 ms, the slow I/O system covers speeds above 1 ms.

The fast I/O system is AC 800PEC specific, using devices connected exclusively via fiber optic links, and brings substantial advantages compared to electric concepts:

− Fast communication between controller and I/O devices

− High immunity to electromagnetic interference

− Potential-free connections, making isolating transmitters obsolete The slow I/O modules from ABB’s S800 system can be added to any configuration, depending on project needs
