Risk Assessments of Aging Aircraft

Abstract

The USAF believes the damage tolerance approach incorporated in ASIP process in the seventies is still the cornerstone for protecting the safety of our aging aircraft. This process is primarily deterministic in that the calculations do not quantify the reliability of the process. As indicated above, however, the reliability achieved is consistent with the new aircraft guidance identified in USAF structural specification. The USAF derives the Force Structural Maintenance Plan (FSMP) from the damage tolerance assessment (DTA). The FSMP prescribes for the maintainer how, when, and where to perform inspections to maintain safety of flight. There are cases, however, where probabilistic methods need to be used. It is the purpose of this paper to illustrate the use of probabilistic methods to ensure structural integrity.
