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. SIMILARITIES TO THE ABOVE MAINTENANCE AND INSPECTION DEFICIENCIES WERE DISCOVERED DURING THE NATIONAL TRANSPORTATION SAFETY BOARD'S INVESTIGATION OF AIR ILLINOIS, INC., HS 748 AIRPLANE ACCIDENT ON OCTOBER 11, 1983, NEAR PINCKNEYVILLE, ILLINOIS. FOLLOWING A COMPLETE ELECTRICAL FAILURE AT NIGHT WHILE EN ROUTE FROM SPRINGFIELD, ILLINOIS, TO CARBONDALE, ILLINOIS, THE AIRPLANE CRASHED, AND THE TEN PERSONS ABOARD WERE KILLED. THE ONLY HS 748 OPERATED BY AIR ILLINOIS WAS DESTROYED. ALTHOUGH THE INVESTIGATION OF THE AIR ILLINOIS ACCIDENT IS NOT COMPLETE, THE SAFETY BOARD HAS FOUND THAT AIR ILLINOIS' MAINTENANCE FUNCTIONS AND INSPECTION FUNCTIONS FOR THE HS 748 AIRPLANE WERE COMMINGLED.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIR CARRIER MAINTENANCE BULLETIN TO EMPHASIZE: (1) THE NEED FOR AIR CARRIER AIRWORTHINESS INSPECTORS TO REQUIRE DURING THE CERTIFICATION PROCESS THAT THE AIR CARRIER'S MANUALS AND MAINTENANCE ORGANIZATIONAL STRUCTURE CONFORM TO REGULATORY REQUIREMENTS REGARDING THE SEPARATION OF MAINTENANCE AND INSPECTION FUNCTIONS, AND (2) THE NEED TO CONDUCT SURVEILLANCE IN A MANNER THAT WILL VERIFY THAT THE AIR CARRIER IS PERFORMING MAINTENANCE/ INSPECTIONS FUNCTIONS AND DUTIES IN ACCORDANCE WITH REQUIREMENTS.
