COCKPIT VOICE RECORDER SPECIALIST'S FACTUAL REPORT OF INVESTIGATION

By Robert D. Rudich

SPECIALIST'S FACTUAL REPORT OF INVESTIGATION

COCKPIT VOICE RECORDER

DCA 71-A-5

A. ACCIDENT

Location: Huntington, West Virginia

Date: November 14, 1970

Aircraft: Douglas DC-9-31, N97S, Southern Airways Charter Flight 932

B. GROUP

Not applicable.

C. SUMMARY

The cockpit voice recorder, although having been substantially damaged externally as a result of impact forces, yielded a satisfactory tape, the communications on which are summarized in the attached transcription.

D. DETAILS OF INVESTIGATION

Installed aboard N97S at the time of the accident was a Collins Model 642-c-1 cockpit voice recorder (CVR), serial number 508. The unit was removed from the aircraft wreckage subsequent to the accident and transported to the Washington Office of the Bureau of Aviation Safety for examination.

Inspection of the CVR revealed that it had incurred considerable damage to the rear electronics package as a result of impact forces. There was no evidence of fire damage. The dust cover was cut away and the stainless steel protective cover removed from the tape package. No damage was noted within the protective steel case. The tape was removed and played for the purpose of preparing rerecordings and the transcription which appears as an attachment to this report.

The tape, during playback, evidenced considerable wow and flutter, indicating a mechanical distress condition during the time that it was recorded. There was marked interference from background noise as well as from communications emanating from the cockpit speakers.

Timing indicated on the attachment is cumulative, starting from the reference point shown, and has not been related to real time. Voice identification was accomplished through the assistance of Southern Airways flight crewmembers, who are familiar with the voices of all three occupants of the flight deck of N97S.
