Boeing 737 MAX の欠陥をめぐる調査にFBIが参加しても真実は明らかにならないだろう

Boeing 737 MAXの耐空証明をめぐる当局とBoeingの癒着疑惑で米国上院がパネルを設置し、この調査にFBIが参加することになったと伝えられています。さて、どこまで明らかになるか。
エアバスとの競争に後れを取ることを恐れて手を抜いたとの見方が有力です。競争に負けないで売り込みを成功させるために最も重要な品質は二の次、競争に負けてしまったら製品の購入を妨害。
武器、戦闘機も欠陥だらけ、そういう米国製品を買わされる日本。

航空に知識のある方は、インドネシアのライオンエア機の墜落ですぐに欠陥機であることに気づいたようです。中国は、特によく把握していた模様。パイロットが異常事態を経験しているはずですから、パイロットのリポートを見ればすぐにわかる。

子供が今月に国際便を利用していたらしい。何年か前に一緒に旅行し成田に無事着陸して私が拍手していたら、息子が今は飛行機はそうそう落ちないんだよ! と抜かした。最近、心配しないでいいからと何度も言われるが、事実心配してもどうなるものではないことはわかっている。

Boeing Scrambles to Test 737 MAX as Indonesian Flag Carrier Dumps $4.9 Bln Order
Test pilots including a pilot from the major US carrier American Airlines expect to test out Boeing's fix for its 737 MAX software this weekend, a pilots' union official has told Reuters.
"This airplane can be a safe airplane, and there have been great strides on getting a fix in the works, but I'll have a better feel after we can test it out, Allied Pilots Association safety committee chairman Mike Michaelis told the agency on Thursday.
According to Michaelis, one American Airlines pilot and one Allied Pilots Association test pilot would be involved in testing out the new software using flight simulators in Renton, Washington, where 737 MAX aircraft are assembled.
The company was left scrambling to fix a bug in its software and provide pilots with related training to "address concerns" the company said it discovered after the accident earlier this month involving an Ethiopian Airlines flight soon after takeoff. The accident was the second crash involving the Boeing plane; last October, a 737 MAX operated by the Indonesian airline Lion Air plunged into the Java Sea shortly after takeoff. Both crashes killed all passengers and crew on board.

'Lost Confidence'
In related news, Indonesian flag carrier Garuda cancelled its $4.9 billion order of 49 737 MAX 8 aircraft on Friday, with a company spokesperson saying its passengers have "lost confidence" in the plane.
"We have sent a letter to Boeing requesting that the order be cancelled. The reason is that Garuda passengers in Indonesia have lost trust and no longer have the confidence" in the plane, Garuda spokesman Ikhsan Rosan told reporters.

Earlier this week, Bloomberg reported that China could drop its order for 737 MAX planes over safety concerns despite earlier plans to include them in a future trade deal with the US.
On Thursday, US media reported that both of the doomed 737s lacked two vital safety features which Boeing had listed as optional. Boeing has promised to rectify the oversight, to upgrade its so-called Manoeuvring Characteristic Augmentation System (MCAS) software and to make previously-optional sensor equipment standard.

Doomed Boeing 737 Max missing 2 key safety features that were sold as ‘optional extras’
An alarming new report says that the two fatal Boeing 737 Max 8 crashes which killed almost 350 people were missing safety features which were sold as optional extras by the manufacturer, and not included as standard.

As entire fleets of the Boeing 737 Max 8 aircraft remain grounded across the globe amid investigations into safety practices at the airline giant, details have emerged about missing safety features, including additional sensors that would have operated as fail safes for the existing ones on board the aircraft and alerted the pilots to any potential issues.

The “angle of attack (AOA) disagree” light warns the pilot when the plane is about to stall based on factors such as the airflow and nose direction, but this does not come as standard when airlines purchase the aircraft.

Another missing feature was the AOA indicator which gives pilots a visual representation of the airflow relative to the aircraft’s nose.

The Maneuvering Characteristics Augmentation System (MCAS) is designed to detect an imminent stall and adjust the plane’s stabilizers to pitch the nose forward to increase airspeed, thus preventing a stall. However, when this is improperly timed, it can be fatal.

To make matters worse, another anti-stall system that does come as standard on the Boeing 737 Max planes reportedly only used one sensor at a time despite having two. Had the additional sensors been fitted and in use, the pilots could potentially have overridden the MCAS and prevented the tragic loss of life.

In response to the tragedies involving Ethiopian Airlines Flight 302 on March 10 and Lion Air Flight 610 five months earlier, Boeing will add the AOA disagree light as an update by the end of April, a source told the New York Times, and both sensors will operate by default. The AOA indicator will still be considered an optional extra, however.

Boeing charges extra for things ranging from superficial things like leather seats to back-up fire extinguishers. Brazilian carrier Gol Airlines reportedly paid $6,700 extra for crew oxygen masks, and $11,900 for a weather radar system control panel.

Former Boeing engineers have reported that the company may have misled the Federal Aviation Authority about the efficacy of and risk associated with the MCAS, adding that Boeing didn’t have any external oversight for the aircraft’s safety certification.

FBI joins criminal probe as US Senate panel set to grill FAA & Boeing over 737 MAX certification
The Federal Bureau of Investigation has joined a multi-agency criminal probe into the certification of the Boeing 737 Max 8, following reports that regulators had delegated much of the troubled plane’s testing to Boeing itself.

The FBI will assist in the inquiry launched by the Department of Transportation’s Inspector General in conjunction with the Justice Department, an investigation that reportedly began before Ethiopian Airlines Flight 302 crashed last week, killing all 157 people on board - the second of the hot-selling Boeing passenger jet to crash in under six months. The scope of the investigation has since widened, with at least one subpoena issued to someone involved in the plane’s development. The FBI would not confirm or deny their involvement in the probe.

A Senate Commerce subcommittee on aviation and space has called a hearing on federal oversight of commercial aviation for March 27 and plans to question acting FAA head Dan Elwell, National Transportation Safety Board chair Robert Sumwalt, and Transportation Department Inspector General Calvin Scovel. The committee, chaired by Sen. Ted Cruz (R-Texas), plans to summon industry stakeholders to a second hearing on aviation safety “in the near future.”

Most of the 737 Max 8s in circulation have been grounded following last week’s crash. A preliminary investigation cited similarities with the October crash of Lion Air Flight 610 and has fingered the Boeing’s onboard autopilot system as the culprit, raising questions regarding how the aircraft passed the Federal Aviation Administration’s safety certification tests and why pilots weren’t made aware of the glitchy software.
