Narrative:Chalk's Ocean Airways Flight 110 departed Fort Lauderdale (FLL) at 13:05 and landed at the Miami Seaplane Base about 13:21. The Grumman G-73T Turbo Mallard was then prepared for Flight 101 to Bimini, Bahamas. It took off at 14:38. While climbing past Miami the right wing separated from the fuselage. Escaping fuel ignited as the Mallard came down out of control. It crashed into the mouth of Government Cut channel off the southern tip of Miami Beach and came to rest in 35 feet deep water.
Investigation revealed that the right wing separated from the accident airplane at wing station 34 because of pre-existing fatigue fractures and cracks in the rear Z-stringer, lower skin, and rear spar lower spar cap.
PROBABLE CAUSE: "The National Transportation Safety Board determines that the probable cause of this accident was the in-flight failure and separation of the right wing during normal flight, which resulted from (1) the failure of the Chalks Ocean Airways maintenance program to identify and properly repair fatigue cracks in the right wing and (2) the failure of the Federal Aviation Administration to detect and correct deficiencies in the companys maintenance program."
