A history of maintenance issues is unfolding at Chalks Ocean Airways, according to a series of recently released NTSB factual reports about last December’s crash of one of the carrier’s Grumman Turbo Mallard G73s in Miami, following separation of the right wing after takeoff. “The right wing fracture surfaces that were examined exhibited evidence of overstress and fatigue,” said the Safety Board. Subsequent examination of two other Chalks Mallards also showed “extensive corrosion” of wing structural components. Further, the NTSB found many “poorly documented and below-standards” repairs to the accident airplane’s wing structure. Pilot morale issues regarding maintenance were ostensibly addressed in August 2004, noted the Board. Mallards have been grounded since the accident.
