ATSB Finds Data Entry Error Caused Safety Risk on Qantas 737 Flight
ATSB report details how a data-entry error led to a Qantas 737-800 departing Canberra overweight, highlighting system and communication failures.
A seemingly minor data-entry mistake by ground staff initiated a complex chain of errors that resulted in a Qantas Boeing 737-800 taking off from Canberra significantly heavier than its flight crew believed. According to a final report released by the Australian Transport Safety Bureau (ATSB) regarding the December 1, 2024 incident, the Commercial-Aircraft departed with incorrect performance calculations, creating a genuine Safety risk that was only mitigated by the pilots’ conservative decision-making.
The incident highlights the fragility of automated safety systems when human operators are under pressure. As reported by ABC News and detailed in the ATSB findings, the error caused the flight management computer to calculate takeoff speeds that were too slow for the aircraft’s actual weight, increasing the potential for a tailstrike or runway overrun.
The sequence of events began when a Qantas staff member in Canberra, reportedly working under high pressure due to weather-related diversions, accessed the flight planning system. According to the ATSB report, the employee inadvertently entered the aircraft code for a Boeing 717, a smaller 125-seat jet, instead of the correct Boeing 737-800, which seats 164 passengers.
While the staff member realized the mistake and corrected the aircraft type code back to a 737, they failed to notice a critical automated consequence of the initial error. When the system briefly thought the flight was a smaller Boeing 717, it automatically “offloaded” 51 passengers (11 Business Class and 40 Economy) to align with the smaller jet’s capacity. When the code was corrected, the system did not automatically re-add these passengers.
Because the 51 passengers were missing from the digital manifest, the final loadsheet issued to the pilots was inaccurate. The ATSB investigation revealed the following discrepancies:
The ATSB described the incident as a failure of the safety system to catch the initial slip, citing “cascading” errors that bypassed multiple layers of defense. Although the initial input was a human error, the subsequent failure to rectify it involved broken chains of communication.
According to the investigation, a Load Control Manager eventually noticed the discrepancy in the system and attempted to contact the pilots via mobile phone, but the call went unanswered. The issue was then escalated to Movement Control, who attempted to radio the crew. However, the pilots had deselected the radio to focus on pre-flight data entry, a standard procedure designed to minimize distractions in the cockpit.
In a final attempt to reach the crew, Movement Control radioed the Gate Agent to pass the urgent message. This action breached standard procedure, which requires direct liaison with the flight crew for critical load errors. Consequently, the message never reached the pilots before the aircraft began its takeoff roll.
Despite the incorrect data, the flight departed safely. The ATSB credited the pilots’ conservative approach to performance planning for preventing a more serious outcome. Rather than utilizing a shorter intersection departure or applying a “headwind credit”, which allows for higher weights or lower speeds based on wind conditions, the crew elected to use the full length of the runway. Dr. Stuart Godley, Director of Transport Safety at the ATSB, noted the importance of these decisions in the official report:
“Fortunately, the flight crew elected to use the full length of the runway… which added an increased safety margin.”
The crew only discovered the error after the aircraft was airborne.
This incident serves as a textbook example of “automation surprise” or bias. When the ground staff member corrected the aircraft type from 717 back to 737, they likely assumed the computer would “undo” all associated changes, including the removal of passengers. This psychological reliance on system logic can be dangerous when software is designed to be conservative (offloading passengers to prevent overbooking) but not restorative.
Furthermore, the “high workload” environment cited in the report underscores a persistent industry challenge. When staff are saturated with tasks, in this case, managing weather diversions, their ability to cross-check automated outputs diminishes. The failure here was not just individual, but systemic, as the software provided no clear warning that the passenger count had been drastically altered following the code correction.
Qantas has acknowledged the findings and accepted the ATSB’s conclusions. In response to the incident, the Airlines has implemented new safety protocols to prevent recurrence. According to the report, airport staff are now required to conduct a manual headcount whenever passenger numbers in the system do not match expected figures, ensuring physical verification before a flight is closed.
Dr. Godley emphasized the broader lesson for the Aviation industry:
“The occurrence demonstrated how a small error can cascade when unusual situations are not proactively identified, addressed, or escalated by those involved in a safety system.”
Was the flight ever in immediate danger of crashing? How common are data-entry errors in aviation? What happened to the staff member involved?

Frequently Asked Questions
While the risk was elevated due to incorrect speeds, the ATSB noted that the pilots’ decision to use the full runway length provided a sufficient safety buffer. Had they used a shorter intersection or less conservative settings, the risk of a tailstrike or runway overrun would have been significantly higher.
Data-entry errors are a known hazard. Similar incidents have occurred in the past, including a 2014 Qantas flight where children were assigned adult weights, and a 2009 Emirates incident in Melbourne where an incorrect weight entry led to a severe tailstrike.
The report focuses on systemic improvements rather than individual punishment. It highlights that the staff member was working under high pressure due to weather disruptions, which is a known human factor in safety incidents.

TWU Calls for Human Dispatchers and Airline Maintenance in AAM Sector
The Transport Workers Union demands certified dispatchers and strict maintenance for advanced air mobility at the upcoming congressional hearing.
This article is based on an official press release from the Transport Workers Union (TWU) and supplementary data regarding the House Transportation & Infrastructure Committee hearing. See the original release for full details.
Ahead of a pivotal congressional hearing on the future of aviation, the Transport Workers Union (TWU) has issued a strong call for the Advanced Air Mobility (AAM) industry to adopt the rigorous safety and labor standards currently applied to commercial airlines. In a press release issued December 2, 2025, the union argued that the emerging sector, comprising electric air taxis and powered-lift aircraft, must not be permitted to bypass established safety protocols regarding aircraft maintenance and operational control.
The demands come just one day before the House Transportation & Infrastructure Committee is scheduled to convene for the hearing titled “America Builds: The State of the Advanced Air Mobility (AAM) Industry.” With industry leaders from companies such as Wisk Aero and Beta Technologies set to testify, the TWU is positioning itself as a check against what it views as a potential erosion of safety standards in favor of automation and cost-cutting.
A central pillar of the TWU’s position is the requirement for certified aircraft dispatchers in AAM operations. Currently, many AAM operators are preparing to launch under Federal Aviation Administration (FAA) Part 135 rules, which govern commuter and on-demand operations. Unlike Part 121 rules, which govern major commercial airlines, Part 135 does not strictly mandate the use of certified dispatchers who share joint responsibility for a flight alongside the pilot.
According to the TWU statement, removing this layer of oversight introduces unnecessary risk into the national airspace. The union contends that dispatchers provide a critical “second set of eyes,” monitoring weather patterns, fuel calculations, and operational hazards independent of the flight crew.
“The TWU insists that AAM operations must utilize certified aircraft dispatchers to ensure a critical layer of safety in complex urban environments.”
This demand places the union in direct conflict with the business models of several AAM developers. Companies like Wisk Aero are pursuing fully autonomous aircraft that utilize ground-based “Multi-Vehicle Supervisors” rather than traditional dispatchers or onboard pilots. The TWU argues that replacing certified human professionals with automated systems or less-regulated oversight roles compromises the safety redundancy that the flying public expects.
Beyond operational control, the TWU is urging lawmakers to enforce strict maintenance standards for the AAM fleet. The union expressed concern that without explicit legislative guardrails, AAM operators might utilize third-party or foreign repair stations that lack the oversight required of major U.S. carriers.
The TWU supports the application of the Global Aircraft Maintenance Standards Act to the AAM sector. Their primary objectives include: Andre Sutton, the International Vice President and Air Division Director for the TWU, emphasized that the advancements in aviation technology should not come at the expense of the skilled labor and safety protocols that have made U.S. aviation the safest in the world.
The timing of the TWU’s demands is significant. In late 2024, the FAA finalized the “Integration of Powered-Lift” Special Federal Aviation Regulation (SFAR), also known as SFAR 120. This rule serves as the interim governing framework for AAM operations for the next decade, effective January 2025.
While SFAR 120 integrates powered-lift aircraft into the national airspace, it largely places them under Part 135 operational rules. This regulatory classification allows for more flexibility than the Part 121 rules used by major airlines like American or Southwest. By lobbying Congress during the “America Builds” hearing, the TWU appears to be seeking legislative intervention to “toughen” these requirements, effectively asking Congress to supersede the FAA’s recent regulatory framework.
The conflict between the TWU and the AAM industry represents a fundamental divergence in vision for the future of flight. For AAM developers, the economic viability of “air taxis” relies heavily on high-frequency, low-cost operations. Business models from companies like Joby Aviation and Archer Aviation depend on keeping operating costs significantly lower than traditional helicopters or regional jets. Adding the regulatory burden of Part 121, including certified dispatchers and strictly domestic, unionized maintenance crews, could threaten the projected margins of these early-stage companies.
Furthermore, the presence of Wisk Aero at the December 3 hearing highlights the industry’s long-term goal of removing the pilot entirely. The TWU’s insistence on human-centric roles (dispatchers and mechanics) serves a dual purpose: it acts as a safety argument in the public eye while simultaneously attempting to secure future jurisdiction for union labor in a sector designed to minimize headcount. As the industry moves toward autonomy, we expect this friction between legacy labor standards and novel operational concepts to intensify.
What is the main difference between Part 135 and Part 121 operations? Why does the TWU want certified dispatchers for air taxis? Who is testifying at the December 3 hearing? What is the Global Aircraft Maintenance Standards Act?

Frequently Asked Questions
Part 121 governs scheduled air carriers (major airlines) and requires the highest level of safety, including certified dispatchers and strict maintenance schedules. Part 135 governs commuter and on-demand flights (like private jets and air taxis), allowing for more flexible operational control and maintenance rules.
The TWU argues that dispatchers provide essential independent oversight, monitoring weather and logistics, that enhances safety. They believe removing this role to save costs increases risk, especially in dense urban airspace.
Witnesses scheduled to appear before the House Transportation & Infrastructure Committee include Kyle Clark (CEO of Beta Technologies), Tyler Painter (CFO of Wisk Aero), Robert Rose (CEO of Reliable Robotics), and Gregory Pecoraro (CEO of NASAO).
It is legislation supported by the TWU intended to close loopholes that allow U.S. airlines to outsource maintenance to foreign repair stations that may not meet the same security and drug-testing standards as U.S. facilities.Sources

DGCA Investigates Air India Airbus A320 Operating Without Valid Safety Certificate
DGCA launches probe into Air India after an Airbus A320 operated multiple flights without a valid Airworthiness Review Certificate amid fleet merger with Vistara.
India’s aviation regulator, the Directorate General of Civil Aviation (DGCA), has initiated a formal probe into Air India after the flag carrier operated a commercial aircraft with an expired safety certificate. According to reporting by Reuters, the airline flew an Airbus A320 on multiple revenue flights in late November 2025 without a valid Airworthiness Review Certificate (ARC), a mandatory document that validates an aircraft’s fitness to fly.
The incident has triggered immediate regulatory action, including the grounding of the specific aircraft and the de-rostering of engineering personnel responsible for the oversight. This development places renewed scrutiny on Air India’s safety protocols as the airline navigates a complex merger with Vistara.
The violation involved an Airbus A320, registered as VT-TQN, which was reportedly one of the aircraft recently inducted into Air India’s fleet from Vistara. According to details summarized in reports by The Economic Times, the aircraft operated eight revenue flights over a two-day period between November 24 and November 25, 2025.
The lapse went undetected until November 26, when Air India’s internal checks identified the expired certificate. The airline subsequently informed the regulator voluntarily. In response, the DGCA ordered the aircraft to be grounded immediately. Both the airline and the regulator have launched separate investigations to determine how the aircraft was cleared for service.
In a statement regarding the incident, an Air India spokesperson acknowledged the failure:
“An incident involving one of our aircraft operating without an airworthiness review certificate is regrettable. As soon as this came to our notice, it was duly reported to the DGCA.”
The operational oversight appears to be linked to the logistical challenges of merging Vistara’s fleet into Air India. Reports indicate that the aircraft in question was the final plane in a batch of 70 former Vistara aircraft undergoing induction. The ARC expired while the plane was grounded for a scheduled engine change. Once the maintenance was completed, engineering staff allegedly released the aircraft for flight without verifying that the ARC had been renewed, a critical step in the post-maintenance release process.
Under India’s Civil Aviation Requirements (CAR), specifically Section 2, Series F, an Airworthiness Review Certificate (ARC) is non-negotiable for commercial operations. It functions as an annual “health check” that validates the aircraft’s Certificate of Airworthiness. Operating without this document is a violation of the Aircraft Rules, 1937, and technically renders the aircraft unairworthy for the duration of those flights.
The DGCA has taken a strict stance on such violations, viewing them as “Level 1” safety lapses because they bypass the fundamental checks and balances designed to ensure passenger safety. This incident is the latest in a series of regulatory hurdles for Air India. The airline has faced consistent scrutiny regarding its safety culture throughout 2024 and 2025. According to reporting by The Hindu, a major DGCA audit conducted in July 2025 flagged 51 safety lapses within the airline’s operations. These findings included deficiencies in pilot training, improper use of simulators, and issues with crew rostering that potentially contributed to fatigue.
The regulator has previously imposed financial penalties on the carrier for similar operational breaches, including fines for pilot qualification issues and violations of flight duty time limitations.
While Air India has characterized this event as a regrettable error discovered through internal checks, the incident highlights a significant vulnerability in the airline’s transition phase. The integration of Vistara, a process involving the unification of fleets, personnel, and digital systems, creates a high-risk environment for administrative and operational slips.
The core issue here may not be solely human error but a failure of digital safeguards. In a robust safety management system, maintenance software should theoretically prevent an aircraft with an expired ARC from being rostered for revenue flights. The fact that the plane completed eight sectors suggests a potential gap in the digital “hard stops” that are supposed to prevent such regulatory breaches. As the DGCA investigation proceeds, the focus will likely shift from the individual engineers to the systemic safeguards that failed to catch the expiration.

FAA Expands FlightLine Surface Awareness System to 55 US Airports
FAA awards uAvionix contract to deploy FlightLine Surface Awareness system at 55 US airports by 2026, enhancing runway safety with ADS-B tech.
On November 24, 2025, the Federal Aviation Administration (FAA) awarded a significant contract to uAvionix Corporation, marking a major expansion of the agency’s efforts to enhance runway safety. The agreement mandates the deployment of the FlightLine Surface Awareness Initiative (SAI) system at 55 additional airports across the United States. This move represents a decisive shift from pilot programs to a nationwide rollout, aiming to equip Air Traffic Control (ATC) towers with advanced surface surveillance capabilities.
The contract stipulates an aggressive timeline, requiring uAvionix to install, test, and achieve full operational status at all 55 sites within 12 months. By November 2026, these airports are expected to possess “radar-like” situational awareness, a capability previously reserved for major hubs equipped with expensive ground radar-systems. This initiative addresses a critical gap in aviation safety by targeting airports that have high traffic volumes or a history of “wrong surface” events but lack traditional surveillance tools.
This expansion is a cornerstone of the FAA’s broader “Surface Safety Portfolio” and aligns with the current administration’s “Brand New Air Traffic Control System” (BNATCS) initiative. By prioritizing commercially available technologies over bespoke, capital-intensive infrastructure projects, the FAA aims to modernize the National Airspace System (NAS) rapidly. The selection of uAvionix follows a series of successful deployments at initial sites, validating the effectiveness and speed of the FlightLine SAI system.
The FlightLine SAI system represents a fundamental departure from legacy surface surveillance methods such as ASDE-X (Airport Surface Detection Equipment, Model X). While traditional systems rely on primary radar and multilateration to track ground movements, FlightLine SAI utilizes Automatic Dependent Surveillance-Broadcast (ADS-B) data. This cloud-based solution captures precise location data broadcast by aircraft and vehicles, displaying it on a map for tower controllers. This approach allows for a clear, real-time depiction of the airfield, regardless of visual conditions.
A key component of this technological ecosystem is the integration of ground vehicles into the surveillance network. The contract includes the deployment of VTU-20 Vehicle Movement Area Transmitters (VMATs). These devices are installed on airport and FAA TechOps vehicles, ensuring they are visible to both controllers and pilots. By broadcasting their positions, these vehicles become part of the digital surface picture, significantly reducing the risk of collisions between aircraft and ground support equipment.
The operational advantages of this system are particularly pronounced during adverse weather. Unlike optical visibility, which is compromised by fog, rain, or darkness, ADS-B data remains consistent. Controllers are provided with a “see-through” capability, allowing them to monitor runway occupancy and taxiway movements with high precision. This data-driven approach enhances decision-making speed and accuracy, directly contributing to the reduction of runway incursions.
“The system provides real-time, precise depictions of all ADS-B equipped aircraft and vehicles on the airport surface, enabling proactive management of potential conflicts, especially critical during low-visibility conditions.”
The 12-month deadline for 55 airports underscores a new emphasis on agility within the FAA’s procurement and deployment strategy. Historically, installing surface surveillance infrastructure could take years. However, the FlightLine SAI system utilizes Commercial Off-The-Shelf (COTS) technology, which drastically reduces installation times. uAvionix has previously demonstrated this capability by completing installations at Richmond International (RIC) and Charleston International (CHS) in fewer than 90 days, with some reports citing a completion time of just 69 days.
While the FAA has not released a consolidated public list of the specific 55 airports included in this latest contract, the expansion builds upon an initial cohort of sites. Airports such as Austin-Bergstrom International (AUS), Indianapolis International (IND), and Jacksonville International (JAX) were among the first to receive the technology. The new contract targets mid-sized hubs and airports with complex runway geometries that require enhanced monitoring. Likely candidates include facilities identified in the FAA’s Surface Safety Portfolio that currently lack major ground radar systems. This initiative is part of a triad of fast-tracked technologies aimed at surface safety. Alongside SAI, the FAA is deploying Approach Runway Verification (ARV), which alerts controllers if a pilot aligns with the wrong runway, and the Runway Incursion Device (RID), a memory aid for tracking closed or occupied runways. The simultaneous rollout of these technologies reflects a comprehensive strategy to layer safety redundancies and modernize air traffic control operations without the extended timelines associated with traditional federal infrastructure projects.
The awarding of this contract to uAvionix signals a definitive step toward modernizing surface safety across the United States aviation network. By leveraging agile, cloud-based technologies, the FAA is moving to close the safety gap at dozens of airports within a single year. The successful execution of this 12-month plan will likely serve as a blueprint for future NAS upgrades, demonstrating that safety enhancements can be delivered rapidly and cost-effectively.
As the aviation industry continues to face challenges related to traffic volume and operational complexity, the reliance on data-driven, satellite-based surveillance will become increasingly standard. The FlightLine SAI rollout not only improves immediate safety metrics but also prepares the infrastructure for future integrations of digital air traffic management tools.

FAQ
FlightLine SAI is a cloud-based system that uses ADS-B data to display the precise location of aircraft and vehicles on the airport surface to air traffic controllers, improving situational awareness.
Unlike traditional radar which relies on bouncing signals off objects and requires heavy infrastructure, SAI relies on aircraft and vehicles broadcasting their GPS position via ADS-B. This allows for cheaper, faster installation and visibility in all weather conditions.
The contract covers 55 additional airports. While the full list is not yet public, it builds on initial sites like Austin (AUS), Indianapolis (IND), and Nashville (BNA), targeting airports with high traffic that lack existing ground radar.
