DECOMPRESSION

On April 28, 1988, an Aloha Airlines Boeing 737, N73711, based at the Honolulu

International Airport, Hawaii, was scheduled for a series of Interisland flights to be conducted under Title 14 Code of Federal Regulations (CFR) Part 121. A captain and first officer were assigned for the first six flights of the day with a planned first officer change to complete the remainder of the daily schedule. The captain checked in for duty about 0510; he completed his pre-departure duties in the dispatch office and then proceeded to the airplane. The crew flew three roundtrip flights, one each from Honolulu to Hilo, Maui, and Kaual. They reported that all six flights were uneventful and that all airplane systems performed in the normal and expected manner. Flight crew visual exterior inspections between flights were not required by Federal Aviation Administration (FAA) accepted company procedures, and none were performed.


DECOMPRESSION

Damage to Airplane A major portion of the upper crown skin and structure of section 43 separated in flight causing an explosive decompression of the cabin. The damaged area extended from slightly aft of the main cabin entrance door, rear ward about 18 feet to the area just forward of the wings and from the left side of the cabin at the floor level to the right side window level. The value of the airplane was estimated at about $5 million. As a result of the accident, the airplane was determined to be damaged beyond repair. It was dismantled on the site and sold for parts and scrap.

DECOMPRESSION

•How much fuel have you got? –> report endurance •How many passengers are onboard? -> report pax on board • How far are you from the threshold?-> report distance from threshold. •How long is the runway? -> advise rwy length •How often have you had that advisory?

in R/T, the words: “say”, “advise”, “report” are used instead of these PLAIN ENGLISH questions.

DECOMPRESSION

•What might cause a sudden decompression of the cabin? •What is the standard procedure in case of decompression? •Do you think that pressurized aircraft are more likely to malfunction than the non-pressurized ones? •What precautionary measures could be taken to avoid decompression?
