the total loss of electrical power due to the flight crew's failure to complete the engine start checklist, or the electrical power failure checklist, which kept the generators off line and resulted in the complete discharged of both batteries.  Also causal to the accident was the captain's failure to perform the emergency landing gear extension checklists, which resulted in a wheels-up landing.
