Vistara Pilot's Alertness Saves Aircraft from Collision at Delhi Airport

A catastrophe was narrowly averted at Delhi Airport when an alert pilot intervened just in the nick of time preventing two Vistara flights, each carrying approximately 150 passengers, from crashing into each other.

The episode occurred on a typical afternoon when the skies were busy with departures and arrivals. The first flight, a Vistara aircraft en route from Ahmedabad to Delhi, had successfully touched down and was directed by the Air Traffic Control (ATC) to cross an active runway on its way to the parking bay. Meanwhile, a second Vistara flight UK725, slated for a flight from Delhi to Bagdogra, was given clearance to take off from the same runway. The planes were 1.8 km, or 1,800 metres, apart, sources said, stressing that if the pilot had not warned ATC of the presence of the other plane, the outcome could have been disastrous.

Captain Sonu Gill, a seasoned pilot at the helm of the Ahmedabad-Delhi flight, spotted the impending danger when the two planes were a mere 1.8 kilometres apart. Captain Gill promptly alerted the ATC of the imminent clash averting the disaster.

What Happened?

According to the Directorate General of Civil Aviation (DGCA), the Vistara flight from Ahmedabad had followed instructions to cross the runway to its designated parking area. However, an ATC official "momentarily forgot" these instructions and greenlit the takeoff of the Delhi-Bagdogra flight from the same runway. “Both were permitted at the same time but ATC took control immediately. The ATC (Air Traffic Control) officer on duty asked Vistara flight to abort take-off,” an official told news agency ANI.

In a statement, the DGCA recounted the tense moments that unfolded: "An alert pilot in the aircraft crossing the runway (VTI926) alerted Air Traffic Control, and the aircraft on its take-off run (VTI725) was ordered to abort take-off." Protocol at the Delhi airport is that no aircraft or vehicle movement is allowed when a plane is in the process of take-off or landing.

The ATC official responsible for the potentially disastrous runway incursion was derostered. The Delhi-Bagdogra flight was deftly manoeuvred back from the active runway to its parking bay. It was refuelled to ensure that the plane had enough fuel to return to Delhi if the pilot encountered bad weather conditions at Bagdogra and braking systems were also checked.

According to airport officials, if the flight taking off had not stopped at the right time, a major accident could have happened. According to Standard Operating Procedure (SOP), no aircraft or vehicle movement is allowed during the process of take-off and landing. Sources said passengers became a little apprehensive when the pilot of the flight bound for  Bagdogra announced that the plane would not take off due to instructions from ATC.

Previous Such Incidents

In 2021, an Air France Boeing 777 crossed an active runway in Mexico City without permission. The uncleared crossing took place around 800 meters beyond the runway's displaced threshold. The flight had not been cleared to cross the runway as it was occupied by a departing Aeroméxico Connect Embraer E190.

Earlier this year, a United Airlines Boeing 777 crossed an active runway in front of another aircraft landing. The near-miss incident also prompted the Federal Aviation Administration (FAA) to conduct an investigation and introduce a formal safety review.

In the ever-evolving world of aviation, the Civil Aviation Administration of China (CAAC) has once again made headlines by granting the Embraer E195-E2, the largest member of the E-Jet series, its Type Certificate. This momentous achievement follows the CAAC's certification of the E190-E2 in November of last year, a milestone that was celebrated during the Zhuhai Air Show.

The aviation industry is no stranger to stringent safety regulations, and the European Union Aviation Safety Agency (EASA) has once again taken a significant step in ensuring the safety of air travel. In response to concerns over the Rolls-Royce Trent 1000 engine's low-pressure turbine (LPT) stage 1 blade assemblies, EASA has issued an Airworthiness Directive (AD). This directive highlights the critical nature of addressing potential safety issues promptly and effectively to maintain the highest standards of aviation safety.

A Critical Alert from Rolls-Royce

The genesis of this Airworthiness Directive can be traced back to Rolls-Royce's issuance of an Alert Non-Modification Service Bulletin (NMSB) Trent 1000 72-AK919. This bulletin specifically pertains to various modifications made to the Rolls-Royce Trent 1000 engine; an engine exclusively utilized on the Boeing 787. The content of this NMSB prompted the issuance of the AD by EASA, emphasizing the gravity of the situation. The directive will go into force on September 5, 2023.

Understanding the Concern

The focal point of the revised directive revolves around the LPT stage 1 blade assemblies, which are identified by Part Number (P/N) FW68788. These assemblies consist of a pair of blades that are welded together at the outer shroud. The concern that has triggered EASA's response is the occurrence of fractures and separation in the weld region of a limited number of these affected parts during engine inspections.

"If a significant number of blade pairs in a blade set are separated, this could change the vibration characteristics of the LPT stage 1 blade set and lead to the release of blade material during engine running," EASA added.

"As a result, secondary damage to the LPT module and subsequent in-flight engine shutdown might result in "reduced control of the aircraft," according to the regulator.

The Significance of the LPT Stage 1 Blade Assemblies

To comprehend the implications of this Airworthiness Directive fully, it's vital to understand the role played by the LPT stage 1 blade assemblies in the operation of the Rolls-Royce Trent 1000 engine. These assemblies are integral components of the engine's low-pressure turbine, a critical section responsible for extracting energy from the exhaust gases to power the engine itself. Any compromise in the structural integrity of these components could potentially lead to catastrophic failures in the engine, with far-reaching consequences.

Operators Dilemma

Operators are required by EASA to check and, if necessary, replace the affected parts. Airlines must examine the Trent 1000 LPT in the shop or while the engine is still on the wing at LPT stage 1 blade assemblies before the part surpasses 30,000 Flight Hours (FH) after initially being put on the engine or within 90 days of the AD's effective date. Following that, inspections must be performed at intervals of no more than 4,500 FHs.

EASA requires inspections before the engine is released back into service for parts that have reached or above the FH threshold and are fitted on engines at a repair shop on the directive's effective date.

However, if cracks or separation are discovered during inspections on an on-wing engine, but not on more than 32 blade pairs, inspection durations must be altered in accordance with the Rolls-Royce NMSB.

Following the implementation date of the AD, operators will be required to replace the damaged parts with new LPT stage 1 blade assemblies during each shop visit, according to EASA. However, the regulator has also permitted airlines to employ functioning engine parts.

Prioritizing Safety

The aviation industry operates under a strict philosophy: safety first. Any identified potential safety risk, no matter how isolated, is treated with the utmost urgency. Rolls-Royce's issuance of the NMSB and EASA's subsequent Airworthiness Directive demonstrate the industry's commitment to ensuring the safety of both passengers and crew members.

Responding to a Concern

The sequence of events leading to the issuance of this directive reflects the industry's proactive approach to safety. It begins with the diligent inspections carried out during routine maintenance checks. In the course of these inspections, reports of fractures and separation in the weld region of the LPT stage 1 blade assemblies surfaced. These reports, although limited in number, prompted immediate action.

Rolls-Royce, as the manufacturer of the Trent 1000 engine, took the responsible step of issuing the NMSB to address the situation. This bulletin contains vital information for operators and maintenance teams, outlining the modifications required to rectify the issue. It serves as a critical communication channel to ensure that all stakeholders are informed and can take appropriate action.

EASA's Role

The European Union Aviation Safety Agency, as a regulatory authority, plays a pivotal role in ensuring compliance with safety standards in the European aviation sector. EASA's response to the NMSB was swift and decisive. They recognized the potential risks associated with the issue and moved to issue the Airworthiness Directive.

The Scope of the Directive

EASA's directive not only underscores the importance of addressing the issue but also provides clear instructions on the actions to be taken. It outlines the inspection and modification requirements, ensuring that the affected components are thoroughly examined, and necessary adjustments are made to mitigate any risks.

Conclusion

In the dynamic world of aviation, safety is paramount. The issuance of an Airworthiness Directive by EASA in response to concerns over the Rolls-Royce Trent 1000 engine's low-pressure turbine stage 1 blade assemblies is a testament to the industry's unwavering commitment to safety. While incidents of fractures and separation may be rare, the industry's response is swift and comprehensive, leaving no room for compromise when it comes to passenger and crew safety.

The FAA awarded such projects $44.9 million and $39.8 million, respectively. Six other airports received funds for improving their taxiways as well.

Illuminating the Way

Advanced Lighting Systems

Visibility is paramount in aviation. Inadequate lighting can pose serious risks, especially during adverse weather conditions or nighttime operations. The FAA recognizes this and has allocated funds to install state-of-the-art lighting systems at airports. These systems will not only enhance visibility during takeoffs and landings but will also guide aircraft safely along taxiways and runways, reducing the likelihood of accidents caused by poor visibility.

Flexibility for Enhanced Safety

Airfield Flexibility

Another vital aspect of this grant is the provision of greater flexibility on the airfield. The ability to adapt to changing circumstances is crucial for ensuring safety in the aviation industry. This funding will be used to create maneuverability within the airfield, allowing airports to better manage traffic, handle emergencies, and accommodate various aircraft types efficiently.

The FAA additionally stated that it has implemented numerous runway safety devices, including as Runway Status Lights and Airports Surface Detection Equipment, Model X (ASDE-X). The latter employs radar, multilateration, and satellite technologies to enable air traffic controllers to follow the movement of aircraft and other ground vehicles. 

Airports in the United States have also begun employing ASDE-X Taxiway Arrival Prediction, which forecasts when flight crews will queue up to land on a taxiway and provides a visual and aural indication to air traffic controllers.

FAA's Commitment to Safety

Shannetta Griffin, the FAA's Associate Administrator for Airports, emphasized the agency's dedication to eradicating runway incursions and enhancing overall safety. She stated, "The FAA is serious about ending runway incursions, and we are putting substantial resources behind our efforts. In some cases, modifying or reconfiguring existing airfields is the best way to address safety risks - these grants directly address those situations."

With this substantial grant, the FAA is not only addressing immediate safety concerns but also taking proactive measures to ensure the long-term safety of air travel within the United States. This bold initiative reflects the FAA's commitment to passenger safety, and it is expected to have a far-reaching positive impact on the entire aviation industry.

Conclusion

The FAA's announcement of a $121 million grant to improve safety at US airports is a pivotal moment for aviation safety. By addressing key areas such as taxiway reconfiguration, advanced lighting systems, and airfield flexibility, the FAA is taking significant steps to enhance safety measures. This investment underscores the FAA's unwavering dedication to passenger safety and its commitment to reducing runway incursions and accidents within US airports.
