Introduction

On April 28, 1988, Aloha Airlines flight 243 underwent an explosive decompression in its passenger cabin at feet 24,000. Although the

Although Aloha followed the manufacturers advised general Maintenance Planning Programme, its management did not implement the specific SBs. Consequently, during the standard inspection activities sporadic cracks and first signs of panel bond disintegration were not identified within the safe crack growth period. It has been debated whether the standard maintenance programme (including four level of Checks, A-B-C-D, at different level of inspection detail and frequency) could have revealed the specific failures in question. The answer is negative: Aloha`s on-ground-examinations were made mainly during night, with limited visual inspection conditions and alertness to identify sporadic rivet cracks. (National Transportation Safety Board, 1989) In sum, the aircraft damage tolerance had become seriously limited which resulted in the catastrophic wear-out failure. C. Human errors and organizational failures
As highlighted before, the investigation identified several types of human failures, including inspection errors and violations of operational procedures. According to Hobbs, maintenance management is critical to ensure aviation safety, and improper maintenance contributes as primary cause to a significant (7-14 %) proportion of aviation accidents and incidents. (Hobbs, 2008) However, individual failures in maintenance activities are usually not the root-causes of failures but affected by the work
