NEW YORK | A frightening collision of one of the world’s largest airliners with a commuter jet on a dark, wet tarmac at John F. Kennedy International Airport is underscoring worries about ground accidents as U.S. airports begin handling a new generation of giant planes.

A total of 586 passengers and crew members were aboard the two aircraft Monday night when the left wing of an Airbus A380 operated by Air France clipped a Bombardier CRJ-700 regional jet flown by Comair, spinning the smaller plane nearly 90 degrees. No one was injured.

The superjumbo Airbus is so immense — as tall as a seven-story building, with a wing span as wide as a Manhattan block — that its wing could have almost cleared the smaller plane. But not quite.

“It’s the sheer size of these aircraft and the congestion at these airports that’s the problem,” said Allan Tamm, a consultant with Avicor Aviation, based in Portland, Ore. “It’s a serious concern for all these airports trying to accommodate these aircraft. It’s going to happen more and more.”

The collision happened at one of the nation’s most congested airports on a rainy night when flashing lights reflecting off wet tarmac can obscure small aircraft. It comes as airports across the country are beginning to receive a new class of huge aircraft.

Fourteen airports have obtained waivers from the Federal Aviation Administration to receive the new Boeing 747-8, which falls into the same new size class as the A380, the Associated Press reported this week. And Boeing is working with 13 more airports to get approval from the FAA, though not all of them may require waivers.

Most U.S. airports cannot legally handle the A380 or 747-8 because of FAA space requirements aimed at keeping planes from bumping into each other. But the FAA can issue waivers if airport officials agree to certain procedures, such as using only certain taxiways or halting other traffic when one of these mammoth planes is on the move.

Many of the airports asking for permission to handle the Boeing 747-8 “are only marginally ready” to handle them, with the difficulties at their worst when aircraft are turning, Mr. Tamm said.

JFK was built in the 1950s, when jets were smaller. Airport officials had to secure FAA waivers for both the A380 and the 747-8. Monday’s collision might spur the FAA to take a second look at JFK’s rules for handling large aircraft, said aviation consultant John Cox.

The National Transportation Safety Board is reviewing radio recordings, radar data and flight recorders from both aircraft in Monday’s accident.

The impact tore open the leading edge of the Airbus’ left wing and broke off half of the wing fence, a vertical fin that sticks out from the wingtip, photos from the NTSB show. The Bombardier had a hole in its rudder and a dent on the leading edge of the tail.

“This wasn’t just two airplanes bumping together. The Air France plane really creamed the regional jet,” said Bill Voss, president of the Flight Safety Foundation, an advocacy group.

The regional jet was carrying 62 passengers and four crew members, the Airbus 495 passengers and 25 crew members. Comair is a regional subsidiary of Delta Air Lines.

Audio of the collision indicates the Comair jet, which had just arrived from Boston, was trying to exit the taxiway as the France-bound Airbus made its way to the runway. But the Comair plane may have stopped short because of congestion in the parking area, Mr. Voss said.

In the dark and rain, “both pilots and controllers would have been confronted with a sea of flashing lights and reflections which could partly explain why the Air France pilot may not have seen the regional jet,” Mr. Voss said.
