The Value of Aircraft Component Reliability Analysis

According to the National Transportation Safety Board, in 2015, there were 1,282 accidents involving civil aviation in the U.S. Of those accidents, a total of 238 involved fatalities, resulting in 406 deaths. And when you consider that system component failures were among the top six leading causes of fatal general aviation accidents between 2001 and 2016, it’s clear that ensuring all aircraft components are of the highest quality is of the utmost importance.

As such, component reliability modeling and aircraft component reliability analysis are critical to airplane safety. First and foremost, when performed properly, they can play a significant role in keeping human lives safe and preventing any other damages associated with aircraft failure. Second, when it comes to ISO (International Organization for Standardization) aviation reliability standards analysis, they can help you pinpoint vulnerabilities you can address to ensure compliance. Finally, ISO aerospace standards analysis can help you meet your own internal criteria regarding reliability and quality.

Aerospace Reliability Standards

Quality control and reliability standards form an integral part of the successful design, manufacture, and assembly of aircraft and aerospace components. For the ultimate in the ease, accuracy, and integration of these standards into the work conducted by aerospace and reliability engineers, the Relyence Platform is intuitively designed to incorporate industry-leading standards. In addition, it supports customizable interfaces to meet the needs of even the most demanding projects.

Some of the most common aerospace industry standards the Relyence Platform supports include:

• MIL-HDBK-217: The Military Handbook: Reliability Prediction of Electronic Equipment — or MIL-HDBK-217 — establishes uniform standards for the reliability of electronic components and systems primarily used by the military. However, since so much of the electronic equipment used in modern aircraft is of a mission-critical nature, MIL-HDBK-217 also plays an integral role in helping the aeronautics industry produce robust electronic devices.
• MIL-STD-1629: MIL-STD-1629A is the standard for FMECA (Failure Mode, Effects, and Criticality Analysis). FMECA is a methodology used to evaluate and assess all potential system failure modes, the resulting effects and possible causes of those failure modes, and ultimately eliminate, reduce, or mitigate the failures deemed most critical.
• MIL-HDBK-472: Proper maintenance of aircraft is of supreme importance for today’s aerospace industry, which is why MIL-HDBK-472 — concerned with maintainability prediction — is so useful. Incorporated into robust maintenance schedules, MIL-HDBK-472 can help engineers and technicians take appropriate maintenance actions before a fault is likely to occur.
