by

Albert G. Reitan Transportation Safety Specialist

The reader of this report is cautioned that the transcription of a CVR tape is not a precise science but is the best product possible from an NTSB group investigative effort. The transcript, or parts thereof, if taken out of context, could be misleading. The attached CVR transcript should be viewed as an accident investigation tool to be used in conjunction with other evidence gathered during the investigation. Conclusions or interpretations should not be made using the transcript as the sole source of information.

C. SUMMARY

A Fairchild model A-100A cockpit voice recorder (CVR), s/n 61216, was brought

to the audio laboratory of the National Transportation Safety Board on August 8, 1997.

The Cockpit Voice Recorder committee convened on August 10, 1997. The group re

conveniened on October 27, 1997 to provide an English and Korean language tran

script. The transcript includes the entire 31:01 minute recording. (attached)

D. DETAILS OF INVESTIGATION

The exterior of the CVR showed no evidence of structural damage. The interior

of the recorder and the tape sustained no apparent heat or impact damage. A Dukane

underwater locator beacon (ULB) was installed and when tested in the laboratory, was

found to operate satisfactorily.

The recording consisted of four channels of good quality audio information.

One channel contained the cockpit area microphone audio information. Three other

channels contained the Captain, First Officer and Second Officer audio panel informa

tion. The fourth also contained interphone and public address information. Timing on

the tape was established using the time of the accident supplied by the Investigator-in

charge.

The transcript starts as the crew is preparing for descent from the cruise altitude

of forty one thousand feet into the Guam International airport. The transcript continues

as the crew briefs for the approach and discusses the usability of the airport I LS sys

tem. The recording ends shortly after the aircraft impacts terrain and power is removed

from the CVR.

CVR Quality Rating Scale

The levels of recording quality are characterized by the following traits of the cockpit voice recorder information:

Excellent Quality Virtually all of the crew conversations could be accurately and easily understood. The transcript that was developed may indicate only one or two words that were not intelligible. Any loss in the transcript is usually attributed to simultaneous cockpit/radio transmissions that obscure each other.

Good Quality Most of the crew conversations could be accurately and easily understood. The transcript that was developed may indicate several words or phrases that were not intelligible. Any loss in the transcript can be attributed to minor technical deficiencies or momentary dropouts in the recording system or to a large number of simultaneous cockpit/radio transmissions that obscure each other.

Fair Quality The majority of the crew conversations were intelligible. The transcript that was developed may indicate passages where conversations were unintelligible or fragmented. This type of recording is usually caused by cockpit noise that obscures portions of the voice signals or by a minor electrical or mechanical failure of the CVR system that distorts or obscures the audio information.

Poor Quality Extraordinary means had to be used to make some of the crew conversations intelligible. The transcript that was developed may indicate fragmented phrases and conversations and may indicate extensive passages where conversations were missing or unintelligible. This type of recording is usually caused by a combination of a high cockpit noise level with a low voice signal (poor signal-to-noise ratio) or by a mechanical or electrical failure of the CVR system that severely distorts or obscures the audio information.

Unusable Crew conversations may be discerned, but neither ordinary nor extraordinary means made it possible to develop a meaningful transcript of the conversations. This type of recording is usually caused by an almost total mechanical or electrical failure of the CVR system.

I will give you a short briefing . . ILS is one one zero three . . NIMITZ VOR is one one five three, the course zero six three, since the visibility is six, when we are in the visual approach, as I said before, set the VOR on number two and maintain the VOR. for the TOD, I will add three miles from the VOR, and start descent when we're about one hundred fifty five miles out. I will add some more speed above the target speed. well, everything else is all right. in case of go-around, since it is VFR, while staying visual and turning to the right at . . . , request a radar vector. if not, we have to go to FLAKE . . . turn towards FLAKE . . . turning towards a course zero six two outbound heading two four two and hold as published. since the localizer glide slope is out, MDA is five hundred sixty feet and HAT is three hundred four feet. it was a little lengthy. this concludes my landing briefing.
