The serious incident aboard Flydubai flight FZ1073 raises a discussion that goes far beyond the reinforced door of an aircraft cockpit.
According to the information available so far, the First Officer allegedly attacked the Captain during the flight and attempted to take control of the aircraft, which was carrying 174 passengers and was bound for Tel Aviv. The situation ended after other people on board intervened, and the aircraft subsequently landed in Saudi Arabia.
An important caveat must be established from the outset: the First Officer’s motive remains under investigation. Therefore, at this stage, it would not be technically appropriate to definitively describe him as a terrorist or to state that a terrorist attack has been confirmed.
But that uncertainty itself makes a broader discussion necessary.
How should a professional authorized to occupy one of the most sensitive environments in civil aviation be selected, assessed and monitored throughout his or her career?
Aviation Security Does Not End at the X-Ray Machine
When we talk about protecting civil aviation against acts of unlawful interference — Aviation Security — most people immediately think of passengers going through metal detectors, baggage screening, X-ray equipment, liquid restrictions, identity checks and reinforced cockpit doors.
That is only part of the system.
There is another, considerably more complex threat: one originating from someone who already has authorized access to the system.
This is known as an insider threat.
Pilots, cabin crew, mechanics, airport employees, ground personnel and other aviation professionals may hold credentials allowing them to cross security barriers that ordinary passengers would never be permitted to cross.
In the case of pilots, there is an additional factor: they do not merely have access to the aircraft and the flight deck. They also possess the technical knowledge and operational authority required to operate the aircraft.
This makes the selection and continuous monitoring of these professionals a genuine security barrier.
Layers of Protection
Modern aviation security is built around the principle of multiple layers.
No single barrier is considered sufficient on its own.
These layers may include:
professional recruitment and selection;
background checks;
document verification;
medical assessments;
psychological and behavioral assessments, where applicable;
initial training;
recurrent training;
Crew Resource Management — CRM;
operational supervision;
organizational culture;
internal reporting channels;
safety and security programs;
access control;
sharing of relevant information;
and continuous monitoring throughout the professional’s time within the organization.
The problem begins when we assume that hiring marks the end of the process.
It does not.
Hiring should only be the beginning.
What ICAO Requires
Annex 17 of the International Civil Aviation Organization — ICAO — dedicated to Aviation Security, establishes an international framework designed to protect civil aviation against acts of unlawful interference.
Its provisions include personnel selection, qualifications, training and background checks for certain functions and access to sensitive areas.
ICAO also establishes requirements for recurrent background checks, at intervals determined by the appropriate authority, for certain individuals performing security controls, holding unescorted access to security-restricted areas or having access to sensitive Aviation Security information.
This detail is extremely important.
The international security framework implicitly recognizes a simple reality:
a person who meets the required standards today will not necessarily present exactly the same profile five, ten or fifteen years from now.
People change.
Personal circumstances change.
Social environments change.
Behavior may change.
And threats evolve as well.
How Does Flydubai Select Its Pilots?
Public information provided by Flydubai indicates that its selection process for First Officers involves considerably more than simply receiving a résumé.
The airline describes stages involving an online application and psychometric testing related to professional behavior, logical reasoning, multitasking and verbal reasoning.
The process also includes a video interview, application review, competency-based interview, technical simulator assessment, pre-employment medical examination and a second non-technical assessment stage, which also includes psychometric evaluation and verification of flight documentation.
It would therefore be incorrect, without access to the investigation and the airline's internal records, to claim that Flydubai simply placed a pilot in the cockpit without an assessment process.
The question that needs to be investigated is different:
What happened after he was hired?
Selection Is Different From Continuous Monitoring
This may be the most important issue raised by the incident.
A good selection process evaluates the professional as he or she exists at that particular point in time.
Continuous monitoring seeks to identify relevant changes that may occur later.
And that distinction is significant.
A pilot may remain within an organization for years or even decades.
During that period, he or she may experience changes in family circumstances, finances, professional life, psychological condition, social environment or ideology.
This does not mean airlines should transform their Human Resources departments into personal surveillance organizations.
That would be inappropriate and potentially invasive.
It does mean, however, that organizations operating safety-critical and security-sensitive activities need mechanisms capable of identifying changes relevant to safety or security, while simultaneously respecting privacy, labor legislation, individual rights and sound technical criteria.
Human Resources Is Also a Security Barrier
In aviation, Human Resources should not be regarded solely as an administrative department.
When dealing with safety-sensitive or security-sensitive personnel, HR indirectly becomes part of the organization's risk-management architecture.
A résumé and a license are necessary.
Flight hours are necessary.
Technical proficiency is necessary.
Operational experience is necessary.
But none of those factors, by themselves, answer the fundamental question:
Who is the professional to whom we are entrusting an aircraft carrying hundreds of people?
And there is a second, equally important question:
Who has that professional become since being hired?
This may be one of the most uncomfortable questions raised by the Flydubai incident.
A Database Does Not Fully Know a Human Being
Technology has made recruitment faster and more efficient.
Résumés are automatically screened.
Documents are digitized.
Algorithms organize applicants.
Tests can be conducted remotely.
Interviews may take place by video.
All of this has enormous value.
But there is a risk when administrative efficiency is mistaken for genuine knowledge of the human being behind the credentials.
A license tells us what ratings a pilot holds.
A database provides known background information.
A medical examination assesses certain conditions.
A simulator evaluates competencies.
A psychometric test provides indicators within defined parameters.
None of these, by itself, fully understands the human being sitting behind the flight controls.
That is precisely why aviation relies on layers.
We Cannot Say There Was Negligence — Yet
There is a fundamental difference between raising a legitimate security question and anticipating the conclusion of an investigation.
Until the competent authorities complete their investigations, there is insufficient evidence to state that Flydubai was negligent in either hiring or monitoring this First Officer.
There may have been a detectable warning sign.
There may have been information that was not adequately shared.
There may have been a behavioral change that went unnoticed.
There may have been a weakness in monitoring procedures.
Or there may simply have been no previous indicator that could reasonably have predicted the behavior.
The investigation will have to answer these questions.
But one question can already be asked:
Were the existing security barriers sufficient to detect a potential change in this professional's risk profile?
That is a legitimate Aviation Security question.
Insider Threat Is Different
Following the September 11, 2001 attacks, one of the major responses adopted by the global aviation industry was the reinforcement of cockpit security.
The objective was to prevent an external threat from reaching the pilots.
The problem is that a reinforced cockpit door primarily addresses one direction of threat:
from the outside in.
When a threat potentially emerges from within the protected environment itself, the security logic changes completely.
The 2015 Germanwings accident had already demonstrated — in a different context and without a terrorist dimension — how a barrier designed to protect the cockpit could become part of a critical scenario when the danger originated inside it.
The Flydubai incident brings this discussion back into focus.
Protecting the cockpit is not enough.
We must continually consider whom we authorize to remain inside it.
Human Labor Is Not Simply a Variable Input
There is a phrase I frequently repeat when discussing human-resource management in aviation:
Human labor is not simply a variable input.
Especially when that human being is operating an aircraft.
Crew members must be carefully selected, trained, assessed and monitored throughout their professional careers.
That does not mean persecuting employees.
It does not mean investigating personal opinions.
It does not mean establishing permanent surveillance over their private lives.
It means recognizing that critical functions require equally mature systems of professional oversight.
An airline may operate modern aircraft equipped with redundant systems, provide advanced training, maintain rigorous maintenance programs and implement sophisticated safety and security systems.
But ultimately, someone will be sitting at the controls.
The Warning From Flight FZ1073
Regardless of the motive ultimately established by investigators, the Flydubai incident should prompt the international aviation community to reconsider the issue of insider threat in civil aviation.
Not only cockpit doors.
Not only procedures.
Not only background checks conducted during recruitment.
But the entire professional lifecycle.
Selection.
Training.
Organizational culture.
Supervision.
Communication.
Recurrent assessment.
Identification of relevant changes.
And the ability to intervene before a risk penetrates every layer of protection.
Aviation safety and security have historically evolved after events exposed vulnerabilities that had previously been underestimated.
Perhaps this incident is revealing another one.
We have built protected airports.
We have created security-restricted areas.
We have installed detectors.
We screen baggage.
We have reinforced cockpit doors.
We have developed passwords and access procedures.
But there is one security barrier that technology cannot completely replace:
properly knowing, selecting and monitoring the people to whom we entrust the aviation system.
This discussion should not be used to prematurely condemn an airline or an individual.
Instead, it should serve the purpose aviation has learned to pursue throughout its history:
identifying vulnerabilities before they become tragedies.
