March 12, 2019, © Leeham News: About 40% of the world’s in-service Boeing 737 MAX fleet were grounded by the end of yesterday, Seattle time, after more governments and airlines banned operations.
Singapore was the latest to ban MAX operations from its air space.
The US Federal Aviation Administration said yesterday there isn’t enough information yet from the Ethiopian Airlines crash Sunday to conclude a grounding order is necessary.
But it added that it will issue an order for a mandatory action by April to make improvements to the flight control system. Boeing late Monday confirmed a software upgrade is in the works for its MCAS stall recovery system used on the MAX.
LNA reported early Monday that a plan to implement a software upgrade following the October crash of a Lion Air MAX 8 had not been implemented.
Update: Royal Air Maroc, Mongolian Airlines ground MAX.
March 11, 2019, © Leeham News: Indonesia regulators today joined China, Grand Cayman Airways and Ethiopian Airlines in grounding the Boeing 737 MAX pending investigations or inspections.
The moves came within 36 hours of the crash of Ethiopian Flight 302, a MAX 8, six minutes after take off from Addis Ababa. The crash killed all 157 people on board five months after a Lion Air 737-8 crash that killed 189 passengers and crew. Lion Air is an Indonesian carrier. The airline’s JT610 crashed 12 minutes after take off.
