● What do Boeing groundings mean for you?

With the entire global fleet of 737s grounded, travellers are likely to pay

- Chrystal Zhang Chrystal Zhang is a lecturer in the Department of Aviation at Swinburne University of Technology, Melbourne.

With investigat­ions under way into two crashes of Boeing’s 737 MAX 8 aircraft, the US manufactur­er has caved to pressure and grounded the entire global fleet of 371 planes. That includes both model 8 and 9 versions of the aircraft.

The company issued a statement saying this occurred “. . . out of an abundance of caution and in order to reassure the flying public of the aircraft’s safety”.

But the impact on passengers and air travel could last for months as airlines try to reschedule flights and seek other aircraft to meet demands. While things are still evolving, what should you anticipate as a traveller?

US President Donald Trump’s order on Wednesday prompted the Federal Aviation Authority to ground all 737 MAX aircraft flying in and out of the US.

While it is legitimate for a government to issue regulatory orders to intervene in an airline’s operation due to safety or security concerns, it is unpreceden­ted that so many countries are taking action.

At least 45 Internatio­nal Civil Aviation Organisati­on member states had already either ordered their airlines to ground 737 MAX aircraft, or suspended entry of such planes into enter their airspaces.

Countries affected include China, Indonesia, Germany, UK, France, the Netherland­s, Singapore, Australia, New Zealand, Canada and the US.

While investigat­ions into the two theconvers­ation.com crashes could last for months or even years, the length of suspension is also unknown at this stage.

Yet holiday seasons such as Easter and school breaks are approachin­g, and many will no doubt be looking to fly away.

Airlines face disruption almost every day, caused by unforeseea­ble weather conditions, unexpected technical or mechanical issues of an aircraft, or associated safety hazards or security concerns.

Airlines therefore have strategies to manage or at least mitigate the effect of the disruption and reduce any potential delays. This could include but is not limited to:

changing or swapping an aircraft type

combining two or three flights into one operation

arranging alternativ­e flights for travellers

moving travellers to other airlines if their tickets have been issued.

With only 371 Boeing 737 MAX family jets in operation, this is a small percentage of the more than 6000 of the previous model and gives airlines the ability to use other jets in their fleet as a replacemen­t.

But the suspension will present significan­t challenges.

Subject to their fleet size, the scope of their network, and other capacity available, big airlines with multiple types of aircraft are more capable of managing such disruption.

In contrast, low-cost or regional carriers will be limited in their capacity to manage the disruption.

For instance, SilkAir and Fiji Airways have six and two Boeing 737 MAX aircraft in their respective fleets. Grounding the model means both carriers lose 16 per cent of their capacity.

While airlines are making every effort to minimise the disruption, all these arrangemen­ts come at a cost.

Airlines might have difficulti­es in sourcing capacity to replace the aircraft, resulting in inevitable delays or cancellati­ons. And delays and cancellati­ons also result in additional cost to airlines operation.

Travellers could soon see an increase in airfares. The rising fuel cost and shortage of pilots have already put global airlines under pressure to manage operationa­l costs.

Boeing and Airbus are a duopoly, said to dominate 99 per cent of the global large aircraft orders, which make up more than 90 per cent of the total aircraft market.

Over the past few decades, Boeing has weathered problems before and maintained an exceptiona­l reputation for its reliable and efficient aircraft design, manufactur­ing and service.

In 2018, Boeing received US$60 billion ($88b) for 806 aircraft deliveries, comparing to Airbus’s US$54 billion for 800 aircraft deliveries. Of all the aircraft sales, the Boeing 737 MAX series — designed to replace the current 737 family — was becoming one of the most popular airliners, despite being only introduced to the market in May 2017.

But the two recent crashes have raised concerns about reliabilit­y of the 737 MAX 8 autopilot system, the Manoeuvrin­g Characteri­stics Augmentati­on System.

Some pilots have complained about a lack of training for the MAX 8. Others complained of problems.

The aircraft represents a significan­t change from its predecesso­r models, including new engines, new avionics and different aerodynami­c characteri­stics.

The risk for Boeing now is the potential consequenc­es flowing from any investigat­ion into the aircraft crashes. These could include:

complete or partial cancellati­on of orders placed by global airlines

litigation by the affected airlines and the victims of the ill-fated aircraft, seeking damages caused by any product defect (if proof could be establishe­d) new opportunit­ies for its rivals to promote their aircraft; this could allow, for example, China’s stateowned aircraft manufactur­er, COMAC, to make new waves. Regardless, Boeing could face enormous financial losses and devastatin­g economic consequenc­es. Boeing’s shares dropped after the Ethiopian Airlines crash on Sunday, but have started to recover. While Boeing surely carries enough insurance coverage for losses, it is inevitable the damage to its brand is more far-reaching in the medium to long term. This will affect the confidence of aircraft operators and the general public. Even if any technical defects discovered are quick to fix, a damaged brand tends to require more time and much more significan­t efforts to recover.

Of course there is a question everyone wants answered: is it safe to fly? The answer is definitely. Statistica­lly speaking, flying on a commercial passenger airliner is the safest mode of transporta­tion. A recent study of US census data puts the odds of dying as a plane passenger at 1 in 188,364. That compares with odds of 1 in 4047 for a cyclist, 1 in 1117 for drowning and

1 in 103 for a car crash.
