737 MAX Grounding
737 MAX Grounding

After over a year and a half on the ground, the Boeing 737 MAX has finally received the green light for return to service.

The US Federal Aviation Authority (FAA) was the first to clear the aircraft for service in November of last year. Over a period of 20 months, FAA employees worked diligently to identify and address the safety issues that have affected the MAX; these are the same safety issues that played a significant role in the tragic loss of 346 lives, aboard Lion Air Flight 610 and then four months later aboard Ethiopian Airlines Flight 302. Both accidents have been attributed to the MCAS system, which became active at the wrong time and caused the aircraft to enter a catastrophic dive.

Since the FAA cleared the aircraft to return to service, other aviation authorities like ANAC (Brazil), EASA (Europe), CAA (UK), TCCA (Canada) and more have also followed suit.

During the month of January Boeing delivered 26 planes, including 21 737 MAXs. More than 400 aircraft were built during the 20 month grounding period.

Who is Currently Flying the 737 MAX?

Since the clearance came through last year, the Boeing 737 MAX has already completed thousands of revenue flights with regular passengers onboard. According to FlightRadar24, around 3406 revenue flights were operated from 9th December 2020 to January 2021; in addition some 600 non-revenue flights have also been tracked, these include the likes of test and delivery flights.

After the clearance was given from aviation authorities, GOL was the first airline to fly the aircraft worldwide. The reintroduction occurred on 9th December with 6 simultaneous flights, all were operating on domestic routes. The majority of the GOL fleet is based in Sao Paulo’s Guarulhos airport.

FlightRadar24 stats show that, since the reintroduction, GOL has flown 1669 revenue flights with the MAX, up until the end of January.

According to the airline, before reintegrating the aircraft into its fleet, training was carried out for 140 pilots in the United States, in conjunction with Boeing, and a “rigorous series” of technical flights have been conducted.

With their first order of 32 units in 2012, the North American company added 36 more jets to their order in 2020. They also have 52 options which, if fully exercised, would take the carrier to as many as 120 737 MAX airplanes.

Before the MAX is added to our fleet, our team of pilots, maintenance technicians and safety experts are putting the plane through its paces; flying more than 19,000 miles and over 50 flight hours to test the aircraft. We’ve activated our training programs as we closely test, verify and implement all the necessary processes to ensure the MAX aircraft meets our high safety standards. At Alaska, safety is always priority number one. If an aircraft is not safe, we won’t fly it.

Ethiopian Airlines

According to the carrier’s chief executive, Tewolde Gebremariam, the African carrier Ethiopian Airlines is satisfied with the modifications that have been made to the flight-control system of the Boeing 737 MAX, stating that they may bring the type back into service in July.
