For example, let’sContinue reading “Just Culture Arguments”

How Unusuality and Reality Intersect in Flight Safety: A Simple Metric for Determining Major Hazards to Commercial Flight Operations from the Unremarkable Accumulation of Minor Unfavorable Elements and a Recommended Operations Adjustment Procedure to Avoid Mishap Occurrence

Abstract: The cascading collection of seemingly minor unfavorable elements during a particular commercial flight can often arouse little notice because there may be no collective safety measuring system or metric to assemble disparate elements. However, just as the story of “the straw that breaks the camel’s back[1]” informs us, flight crew members facing unusual accumulationsContinue reading “How Unusuality and Reality Intersect in Flight Safety: A Simple Metric for Determining Major Hazards to Commercial Flight Operations from the Unremarkable Accumulation of Minor Unfavorable Elements and a Recommended Operations Adjustment Procedure to Avoid Mishap Occurrence”

MH370 Solved?: Did Antenna Bracket Failure Rip Open Fuselage Hole?

Did an unfinished FAA/Boeing Air Safety Directive or AD doom MH370? Reinforcement to the fuselage mounting bracket for certain radio antennae on B777 aircraft may have been required by a recent FAA AD. However completion was allowed for an extended period. Metal fatigue and other cracking failure modes common on aluminum cyclically pressurized fuselages couldContinue reading “MH370 Solved?: Did Antenna Bracket Failure Rip Open Fuselage Hole?”

Battery Cargo Lobbyists Victorious over Commercial Aviation Safety? What Happened to MH370?

Though ticketed passengers did not suspect, battery lobbyists had been victorious over the very best commercial aviation safety advocates. Through private meetings, where financial benefits of shipping dangerous lithium batteries to the battery industry by air freight are fostered, did lobbyists convince passenger airline executives to allow carriage onboard passenger commercial flights? Many commercial aviationContinue reading “Battery Cargo Lobbyists Victorious over Commercial Aviation Safety? What Happened to MH370?”

UPS 1354, Birmingham Runway 18, August 14, 2013: Is FAA Policy vs Procedures Inconsistency Causing A Severe Safety Risk in Commercial Aviation? “Is the Tail Wagging the Dog ?”

In the last 40 years the US FAA has spent hundreds of billions of taxpayer dollars engineering safety into the nation’s commercial aviation infrastructure. This policy at the FAA has led to great success in achieving an astonishing low commercial aviation mishap rate in the US.  Moreover it has provided an example for Western Europe,Continue reading “UPS 1354, Birmingham Runway 18, August 14, 2013: Is FAA Policy vs Procedures Inconsistency Causing A Severe Safety Risk in Commercial Aviation? “Is the Tail Wagging the Dog ?””
