Plane's Wing Had Cracks in Beam, NTSB Says
Crash Off Miami Beach Kills All 20 on Board

MIAMI BEACH, Fla. (Dec. 21) - The wing that fell off a seaplane before it crashed, killing all 20 people on board, had cracks in the main support beam that had probably gone unseen for a long time, federal investigators said Wednesday.
Mark Rosenker, acting chairman of the National Transportation Safety Board, stopped short of saying the cracking was the sole reason the right wing fell off the 58-year-old plane Monday shortly after it took for the Bahamas.
But Rosenker told a news conference that the cracking should have been found and repaired, although it would have taken "a very serious" inspection to find it.
The Chalk's Ocean Airways plane plummeted into the Government Cut channel off the southern tip of Miami Beach in front of horrified beachgoers.
The cracks were in the main support beam that connected the wing to the fuselage. Rosenker said that if Chalk's officials had known about the cracking "they would have repaired it and we wouldn't be here today. I don't think they knew it."
The propeller and engine were still attached when salvage crews raised the right wing from the channel Tuesday. Crews began raising the rest of the plane from 35 feet of water Wednesday and Rosenker said inspectors will closely examine the remaining part of the support beam.
The salvagers will use balloons to float the plane's fuselage to the surface slowly to avoid damaging it any further, Coast Guard spokesman Dana Warr said.
Investigators also planned to scour maintenance and flight records for evidence of work done on the plane.
Rosenker said the plane's age could have been a factor in the cracking. The plane was retrofitted in the 1980s with more powerful engines, but it wasn't clear what role if any that played in the cracking, Rosenker said.
Chalk's officials had no immediate comment Wednesday.
Rosenker said the NTSB will have discussions with the Federal Aviation Administration and Chalk's about whether to ground its remaining four Grumman G-73T Turbine Mallards. He said other U.S. and foreign operators also fly the plane, but he wasn't sure how many are still in operation.
Warr said the Coast Guard is hoping to get the Port of Miami fully operational soon after the salvage operation is complete. Access to the port was closed again Wednesday so that the salvage operation can continue. The port is one of the largest cruise and cargo terminals in the country.
"We know the impact this is having on the ports and the economy," Warr said.
Older airplanes have been a concern for federal safety officials since 1988, when fatigue cracking caused the roof of an Aloha Airlines Boeing 737 to peel off over Maui. A flight attendant was sucked out of the airplane and lost at sea. The Aloha 737 was 19 years old when the accident occurred, but it had taken off and landed more than 80,000 times.
That accident, and a subsequent law passed by Congress in 1991, prompted the FAA to step up its requirements for inspections and maintenance of aging aircraft.
Eighteen passengers -- including three infants -- and two crew members were on Monday's flight. At least 11 of the victims were returning home to the Bahamian island of Bimini, many of them after Christmas shopping jaunts. Weeping islanders went house to house Tuesday to grieve.
"The island at this time is in an uproar," said Walter Stuart of Miami, who lost 11 family members in the crash.
The plane that crashed Monday previously had few major reported incidents, and no passengers or crew were injured in any of them, according to the FAA.
Chalk's Ocean Airways was founded in 1919, and its aircraft have been featured in TV shows like "Miami Vice." Its floating planes take off in view of the port and waterfront multimillion-dollar homes.
