Need for Scientific risk assessment,6E-11 A320 NEO Engine failure:mindFly

The A-320 NEO PW engines have been plagued with engine failures ever since they were launched. While the Indian DGCA restricted the flights over water to mitigate the risk of ditching, their risk assessment apparently did not cover flights over mountains. On 29th March 2019, 6E11 on route from Delhi to Istanbul suffered an Engine Failure just as she had entered Iran airspace and prior to overflying high ground. The aircraft carried out the escape route maneuver to divert and land safely at Kuwait. While the risk assessment carried out by DGCA India has not been released for public viewing,…

Using Simulator data for evaluation and safety performance: mindFly

Every flight crew involved in an accident/incident is flying the aircraft due to the fact that they have undergone the necessary training and have demonstrated their proficiency/competency. Since the flight crew is the last line of defense and as Prof. Patrick Hudson puts it is the first person at the scene of the accident/incident. The question that naturally arises is, why did the crew not prevent the accident/incident if they were adequately trained and had demonstrated their ability to fly safely? In his 1931 book “Industrial Accident Prevention, A Scientific Approach”, Herbert W Heinrich put forward the following concept that became…

Multi-Crew performance when under evaluation: mindFly

The performance of flight crew when subjected to an evaluation under simulated or real conditions can be very different as compared to a normal line flight. It may deteriorate in some cases and may even improve in others. How do humans perform when working in a group and being judged at the same time, determines their performance. The three main factors that affect the performance are: Objective self awareness Social facilitation, and  Anxiety These three factors each affect performance as a function of their magnitude and direction. In general, task performance is facilitated by a low anxiety state, presence of…

It is not the critic who counts: mindFly

“It is not the critic who counts: not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself for a worthy cause; who, at the best, knows, in the end, the triumph of high achievement,…

Boeing’s design change process:mindFly

All aircraft, engines, and propellers must meet and maintain minimum standards for design, material, construction, quality of work and performance before they can be produced and operated. The International Civil Aviation Organization (ICAO) requires each contracting state to adopt airworthiness standards for the design and performance of aeronautical products. States must ensure that aircraft, including components (engines and propellers), meet these airworthiness standards. ICAO allows states to accept a product approved by another ICAO contracting state without further showing, or to validate another country’s determination that a product meets airworthiness standards.

How is the Ethiopian Airline accident different from Lion Air: mindFly

The Ethiopian Airlines accident on 10th March 2019 was the 2nd B-737 Max accident in 4 months. This created a public outcry about the safety of Boeing 737 around the world and given the fact that Boeing had not been forthcoming in its disclosure of the new software, MCAS.All  countries flying the B-737 had to ground the aircrafts flying in their airspace and the last but not the least the FAA very reluctantly followed suit. Every one tried to draw similarities between the accidents stating that the flight profile was similar and that both the aircrafts nose dived shortly after…
