FAA approval process relies on Boeing to self-police

FAA approval process relies on Boeing to self-police A former associate administrator says FAA does not have the resources to certify aircraft without the help of the manufacturer . "On some level, the FAA is taking Boeing's word for a lot of this," Van Cleave pointed out. "They are taking Boeing's word, but they – Boeing is also presenting data to prove their word," Brenner said.   As far back as 1993, the government accountability office warned "FAA's certification staff were falling far behind industry in technical competency" in part because of delegating to manufacturers.

Boeing Co said in a statement that it had alerted pilots to the issue . The captain and first officer flying from Bali to Jakarta the night before the crash had indicators displaying differences in angle of 20 degrees, KNKT said, but that flight landed safely despite the issues in the air.

switch to the US edition. The Boeing 737 MAX 8, a brand new plane only registered in November, disappeared from the radar six minutes into the flight. Pilots worldwide were angered after the Lion Air crash that subtle software modifications to the MAX 8’s autopilot had not been fully communicated.

REUTERS/Shannon Stapleton Airline pilots on at least two flights have reported that an automated system seemed to cause their Boeing planes to tilt down suddenly, the same problem suspected of contributing to a deadly crash in Indonesia.

The pilots said that soon after engaging the autopilot on Boeing 737 Max 8 planes, the nose tilted down sharply. In both cases, they recovered quickly after disconnecting the autopilot.

The Max 8 is the same plane at the center of a growing global ban by more than 40 countries following a second fatal crash, this time in Ethiopia, in less than five months. In the U.S., however, the Federal Aviation Administration and airlines continued to permit the planes to fly.

Justice Department issues subpoenas in criminal investigation of Boeing

Justice Department issues subpoenas in criminal investigation of Boeing US Justice Department prosecutors have issued multiple subpoenas as part of an investigation into Boeing's Federal Aviation Administration certification and marketing of 737 Max planes, sources briefed on the matter told CNN. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); The criminal investigation, which is in its early stages, began after the October 2018 crash of a 737 Max aircraft operated by Lion Air in Indonesia, the sources said.

Boeing didn't tell airline pilots about features of a new flight-control system in its 737 Max that reportedly is a focus of the investigation into last The bulletin included new details on how to stop a runaway series of events from leading to a crash, pilots say. "It is something we did not have before

The issue of airworthiness is crucial because of concerns over technical issues with the new Boeing 737 MAX that crashed and questions over the The APA, a US airline pilots ’ union, said carriers and pilots had not been informed by Boeing of certain changes in the aircraft control system installed on

American Airlines and Southwest Airlines operate the 737 Max 8, and United Airlines flies a slightly larger version, the Max 9. All three carriers vouched for the safety of Max aircraft on Wednesday

The pilot reports were filed last year in a data base compiled by NASA. They are voluntary safety reports and do not publicly reveal the names of pilots, the airlines or the location of the incidents.

It was unclear whether the accounts led to any actions by the FAA or the pilots' airlines.

In one report, an airline captain said that immediately after putting the plane on autopilot, the co-pilot called out "Descending," followed by an audio cockpit warning, "Don't sink, don't sink!"

The captain immediately disconnected the autopilot and resumed climbing.

Pilots should follow Boeing ’s manual when confronted with this anomalous situation, the company initially wrote in its advisory last week. Hannah Beech reported from Bangkok, James Glanz and Hiroko Tabuchi from New York, and Zach Wichter from Seattle.

Boeing installed the system on the new 737s as part of the “control law” — commands issued by the plane’s flight-control computer that bypass the pilots . On the Lion Air flight, the swings up and down may have come about as pilots repeatedly tried to keep that system from pushing the nose of the

"With the concerns with the MAX 8 nose down stuff, we both thought it appropriate to bring it to your attention," the captain wrote. "Best guess from me is airspeed fluctuation" due to a brief weather system overwhelming the plane's automation.

On another flight, the co-pilot said that seconds after engaging the autopilot, the nose pitched downward and the plane began descending at 1,200 to 1,500 feet per minute. As in the other flight, the plane's low-altitude-warning system issued an audio warning. The captain disconnected autopilot, and the plane began to climb.

The pilots talked it over later, "but can't think of any reason the aircraft would pitch nose down so aggressively," the co-pilot recounted.

Preliminary information released by Indonesian investigators suggests they are looking at the possible role of the Max's new automated anti-stall technology as a factor in a Lion Air crash in October shortly after takeoff from Jakarta. Data indicates that the pilots struggled with repeated nose-down commands from the plane before it crashed into the Java Sea and killed 189 people.

Concern about the Max's safety seemed to be abating but returned on Sunday when an Ethiopian Airlines Max 8 crashed shortly after takeoff from Addis Ababa, killing all 157 people on board. Again, preliminary data appears to capture a brief and erratic flight. Investigators will analyze information from the planes so-called black boxes in hopes of understanding what caused the accident.

Pilot Who Hitched a Ride Saved Lion Air 737 Day Before Deadly Crash.
As the Lion Air crew fought to control their diving Boeing Co. 737 Max 8, they got help from an unexpected source: an off-duty pilot who happened to be riding in the cockpit. That extra pilot, who was seated in the cockpit jumpseat, correctly diagnosed the problem and told the crew how to disable a malfunctioning flight-control system and save the plane, according to two people familiar with Indonesia’s investigation. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.
