In 1988 the Federal Aviation Administration initiated a substantial research program to better understand the issues related to the aging commercial aircraft fleet. A motivating factor for this research was the Aloha Airlines accident in which a portion of the fuselage tore away from an aircraft in flight. The National Transportation Safety Board investigated several causes for the accident. One of these is a phenomenon commonly referred to as multiple site damage or MSD. An inspection schedule and repair had been generated and published by Boeing as early as 1972 for several of the lap splices in the most heavily used, early B-727 and B-737 aircraft. The report describes a program initiated by the FAA to investigate the conditions under which lap splice MSD can occur and whether the required repair technique is likely to be effective.
