Aircraft maintenance is an integral component of an aviation system. 21% of all reported incidents in the Aviation Safety Reporting System (ASRS) are fatigue-related, and 18% of all accidents have maintenance factors involved. Guidelines for Maintenance Resource Management (MRM) are hence developed ...
In a year that saw half the number of flights of the previous year, there were still three fatal accidents and six hull losses. The industry fatal accident and hull loss rates are steadily decreasing over time, but this trend faces a unique challenge due to the many aircraft grounded at ...
Aerospace and Aviation researcher Dr. Graham Wild said the development of Structural Health Monitoring (SHM) systems could significantly reduce the number of aircraft fatigue accidents, such as the catastrophic engine failure on a Boeing 777 over Denver in February 2021. "Early findings from the inve...
Information (risks) inputted to the PFRA by the pilot related to (1) pilot and crewmember, such as pilot experience as single pilot, at current base/program, and using night vision goggles; (2) aircraft, such as MELs and aircraft weight within 200 lbs of max HOGE; and (3) flight requ...
These fatigue striations are unfortunately almost never observable in steels, but they can be an invaluable tool for investigating fatigue failures in aluminium alloys, particularly in aircraft accidents. The striations on the fracture surface can be counted, like the rings on a tree stump, to ...
New York in February 2009 for spearheading the effort to address fatigue. Although US National Transportation Safety Board (NTSB) did not conclude that fatigue as a casual factor in the loss-of-control crash, which killed all 49 on the aircraft and one on the ground, officials considered fati...
It had been overhauled in December 2014 at just over 17,000 cycles before being installed on the aircraft involved in the incident. Since the failure, says the inquiry, the maintenance and overhaul organisation has introduced another inspection procedure specifically to identify any journals which...
During the first 60% of fatigue life, multiplets were mainly detected under tension, hence related to crack growth. In the later stages of fatigue, we also observed AE multiplets under decreasing (\(\sigma < 0;\,\dot{\sigma } > 0\)) and, to a lesser extent, increasing (\(\sigma <...
Indeed, ultra-long-life fatigue continues to be a major safety concern, specifically on modern military aircraft flying with 3D printed components and in aging aircraft in which parts have already been exposed to a large number of loading cycles. This results in more frequent engine maintenance ...
fatigue lifeThe minimum life of a component, or the entire aircraft, in term of the number of hours or number of operating/load cycles before which the component (or aircraft) is designed to function without fatigue failure. Also known as thetechnical life. ...
