Flying has never been safer.

You’re more likely to die from being attacked by a dog than in an airline accident (see chart).

And yet, according to a recent Allianz Global Corporate & Specialty (AGCS) report, the aviation sector’s insurance claims continue to grow in number and size.

The report – Aviation Risk 2020 – says 2017 was the first in at least 60 years of aviation in which there were no fatalities on a commercial airline. The year 2018, in which 15 fatal accidents occurred, ranks as the third safest year ever.

Of more than 29,000 recorded deaths between 1959 and 2017, the report says, fatalities between 2008 and 2017 accounted for less than 8 percent – despite the vast increase in the number of people and planes in the air since 1959.

So, what gives?

Safety is expensive

Some of the reasons for the increased claims are good ones: Safer aircraft cost more to repair and replace when there are problems.

The report analyzed 50,000 aviation claims from 2013 to 2018, worth $16.3 billion, and found “collision/crash incidents” accounted for 57 percent, or $9.3 billion. Now, this may sound bad, but the category includes things like hard landings, bird strikes, and “runway incidents.”

The AGCS analysis showed 470 runway incidents during the five-year period accounted for $883 million of damages.

Engine costs more than the plane

Today’s aircraft contain far more sophisticated electronics and materials than those flying in the 1960s. When they bump into each other or come down too hard, they cost more to repair.

“We recently handled a claim where a rental engine was required while the aircraft’s engine was repaired,” said Dave Watkins, regional head of general aviation, North America, at AGCS. “The value of the rental engine was more than the entire aircraft.”

When entire fleets have to be grounded – the report cites the 2013 grounding of the Boeing Dreamliner for lithium-ion battery problems and the more recent fatal crashes involving the Boeing 737 Max – costs can really soar. Boeing reportedly has set aside about $5 billion to cover costs related to the global grounding of the 737 Max.

Even after a fix is found, the task of retrofitting a fleet takes considerable time – and, in the aviation industry, time truly is money.

Liability awards take off

Compounding the claims associated with the costs of safer flight, the report says, liability awards have risen dramatically.

“With fewer major airline losses,” Watkins said, “attorneys are fighting over a much smaller pool and are putting more resources into fewer claims, pushing more aggressively for higher awards.”

Today’s aircraft carry hundreds of passengers at a time. With liability awards per passenger in the millions, a major aviation loss could easily result in a liability loss of $1 billion or more.
