Narrative:

Aircraft was direct to docay intersection from south for the RNAV 36 approach at mgw airport. MVA vicinity [of] docay/mgw is 35; MVA area just south of docay is 33. Prior to docay; the aircraft was observed descending to 30. A low altitude warning was given with a climb back up to an altitude appropriate with the MVA (035) for the segment of the approach prior to docay however (and without listening to the tapes); I believe I may have given the pilot an incorrect crossing altitude at docay of 33 which was then compounded by the pilot descending even lower than what I mistakenly may have issued. Aircraft was able to successfully complete the approach and land at mgw airport. Not to excuse the incorrect altitude given; it's possible I may have been distracted at the time performing controller in charge related duties.no procedural recommendations; controller error sole factor. Two foot deviation from appropriate altitude for segment of approach.

Title: CKB Controller reported possibly issuing an altitude below the MVA; to an SR22; causing a low altitude alert.

Narrative: Aircraft was direct to DOCAY intersection from south for the RNAV 36 approach at MGW airport. MVA vicinity [of] DOCAY/MGW is 35; MVA area just south of DOCAY is 33. Prior to DOCAY; the aircraft was observed descending to 30. A low altitude warning was given with a climb back up to an altitude appropriate with the MVA (035) for the segment of the approach prior to DOCAY however (and without listening to the tapes); I believe I may have given the pilot an incorrect crossing altitude at DOCAY of 33 which was then compounded by the pilot descending even lower than what I mistakenly may have issued. Aircraft was able to successfully complete the approach and land at MGW airport. Not to excuse the incorrect altitude given; it's possible I may have been distracted at the time performing CIC related duties.No procedural recommendations; controller error sole factor. Two foot deviation from appropriate altitude for segment of approach.
