Introduction

March 28, 2019, © Leeham News: Boeing 737 MAX pilots learning about the revised software upgrade to the Maneuvering Characteristics Augmentation System (MCAS) will need a half hour of computer-based training (CBT), the company told the media yesterday in a briefing.

Pilots of the 737 NG who have not yet made the transition to the MAX also have to be trained on the MCAS now. Boeing did not specify if this will take longer than those already trained on the MAX.

Summary
  • No estimate to MAX return to service.
  • Waiting for investigations of the crashes.
  • More information for pilots.

Pontifications: 737 MAX events remind of Lockheed Electra story

By Scott Hamilton

March 18, 2019, © Leeham News: There’s a saying that history repeats itself.

When it comes to the crisis of the Boeing 737 MAX, I’m reminded of the crisis Lockheed faced in 1959-1960 when the Electra propjet crashed in September and the following March, killing all aboard both airplanes.

The Electra entered service Jan. 12, 1959, with Eastern Airlines. It was considered a pilot’s airplane. Coming off decades of piston engine aircraft and early in the jet age, the Electra was the only airplane that was over-powered, piston or jet. Timing, however, was poor and crashes soon overtook the euphoria.

March 12, 2019, (c) Leeham News: EASA, the European air safety regulator, grounded the Boeing 737-8/9 operated by EU airlines and banned operation of the airplanes operated by third-party airlines/countries.

The press release is here.

The US Federal Aviation Administration still is silent about grounding the airplanes in the US.

UK bans MAX; China checked with Boeing, FAA before grounding

March 12, 2019, © Leeham News: Australia and the United Kingdom today joined a growing list of countries banning the Boeing 737 MAX from operating in or through their airspace.

The UK’s decision to ban the MAX is, up to now, the most important development in the growing crisis of confidence in the safety of the MAX.

The UK and continental Europe’s regulators, EASA, are considered tough regulators who usually work in concert with the USA’s Federal Aviation Administration. That the UK authority is now ahead of the FAA is crucial. If EASA follows suit, the blow to the FAA and to Boeing will be huge.
