Unsafe Condition
Failure of the left hand (LH) and right hand (RH) essential bus when engine failure results in a blown generator current limiter, which could result in loss of airplane electrical power.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Relocate the LH and RH essential bus current limiters (225 amp) to the battery bus (main bus tie) in accordance with Fairchild Aircraft Engineering Kit Drawing 27K82376 and referenced service bulletins. Special flight permits may be issued under 14 CFR 21.197 and 21.199 to operate the airplane to a location where the requirements can be accomplished.
