OF THE EIGHT PERSONS ABOARD THE AIRPLANE, SEVEN RECEIVED SERIOUS INJURIES AND THE OTHER RECEIVED MINOR INJURIES. THE AIRPLANE WAS DESTROYED. THE SAFETY BOARD'S INVESTIGATION DISCLOSED THAT THE DISTINCTION AND SEPARATION BETWEEN THE COMPANY'S INSPECTION AND MAINTENANCE REQUIRED BY 14 CFR 135.423(C) DID NOT EXIST.
