Cockpit Voice Recorders: Transcripts: Aloha 243

On a regularly scheduled flight from Hilo to Honolulu, Hawaii, Alhoa Airlines flight 243 took off and climbed to a cruise altitude of 24,000 feet. It was at that level when the ceiling area of the forward passenger cabin suddenly burst open in an explosive decompression. The ceiling separated from the airplane, leaving the passengers from the cockpit door to the front of the wing exposed to the elements as though they were riding in a convertible car. Riding along in terror, they could do nothing as the aircraft dove to an altitude level (around 11,000 feet) where oxygen was not needed. There were two pilots aboard that early afternoon, an observer in the cockpit jumpseat, three flight attendants, and 89 passengers. We pick up the CVR just as the ceiling rips off.

Cabin: [Sound of screams, sound of wind noise]

The CVR microphones in the cockpit could not pick up any crew conversation for the next five minutes. However, the CVR recorded the crew’s transmissions with the ground control through the crew’s oxygen mask microphones.

Co-pilot: Centre, Alhoa two forty three. We’re going down…request lower [altitude]. Centre, Alhoa forty three, Centre, Alhoa forty three. Maui Approach, Aloha two forty three. Maui Tower, Alhoa two forty three. Maui tower, Alhoa two forty three. We’re inbound for a landing. Maui Tower, Alhoa two forty three.

Tower: [Flight] Callin’ Tower say again.

Co-pilot: Maui tower, Aloha two forty three, we’re inbound for landing. We’re just, ah, west of Makena, descending out of thirteen [13,000 feet], and we have rapid depr - we are unpressurised. Declaring an emergency…

Tower: Aloha two forty three, winds zero four zero at one five. Altimeter two niner niner niner. Just to verify again. You’re breaking up. Your call sign is two forty - four? Is that correct. Or two forty three?

Here the crew, having reached 11,000 feet takes off its oxygen masks.

END OF TAPE.

The Boeing 737 of Alhoa Flight 243 was manufactured in 1969 and had accumulated 35,496 flying hours and 89,680 take - off - landing cycles. The cause of the separation of the ceiling of the aircraft was attributed to static overstress separations. The airplane was old, and the cycles of pressurisation and depressurisation had weakened parts of the fuselage. One flight Attendant was killed. All the passengers landed safely, though 65 of them were injured to varying degrees, mostly
