On April 28, 1988, Aloha Airlines Flight 243, a Boeing 737-297, was a scheduled passenger flight that encountered a catastrophic in-flight accident.

The flight, which was traveling from Hilo to Honolulu, Hawaii, had 59 passengers and 5 crew members on board.

After taking off from Hilo and reaching cruising altitude in clear weather without any issues, the aircraft suddenly experienced structural vibrations.

Approximately 19 minutes into the flight, at around 24,000 feet, the plane suffered a sudden decompression when a large section of the fuselage—about 19 feet long—tore away.

This incident was attributed to severe metal fatigue and corrosion that had compromised the airframe over time.

Captain Richard A. M. “Rick” K. K. Kondo and First Officer Madeline “Mimi” M. M. K. M. Lee demonstrated remarkable composure and skill in managing the emergency. They quickly initiated a descent to regain control and communicated with air traffic control.

Despite the extensive damage, the crew successfully landed the aircraft at Kahului Airport on Maui, approximately 12 minutes after the incident began.

An in-depth investigation by the National Transportation Safety Board (NTSB) revealed that the accident was primarily caused by metal fatigue and inadequate maintenance practices.

The airline had failed to properly monitor and repair the aging fuselage, which had been exposed to harsh environmental conditions in the Hawaiian Islands.

The investigation pinpointed fatigue cracking around rivets as the primary cause of the fuselage failure, exacerbated by the aircraft’s frequent pressurization and depressurization cycles in a salty coastal environment.

The incident involving Aloha Airlines Flight 243 is frequently referenced in discussions of aviation safety, underscoring the critical need for regular inspections and maintenance of aging aircraft.

It highlighted the importance of monitoring structural integrity and understanding the effects of environmental factors on airframe materials.

Fortunately, there were no fatalities among the passengers and crew; however, one flight attendant was partially ejected during the decompression and did not survive.
