Aviation Expert Richard Godfrey Attributes AI 171 Crash to RAT Deployment, Rules Out Pilot Error Aviation expert Richard Godfrey has identified the automatic deployment of the Ram Air Turbine (RAT) as the primary cause of the Air India Flight 171 crash in Ahmedabad on June 12, dismissing widespread speculation that pilot error was to blame. In an interview with Geoffrey Thomas, Godfrey examined preliminary findings and data released by the Air Accident Investigation Bureau (AAIB) a month after the London-bound aircraft crashed, resulting in the deaths of all but one passenger. Timeline and Key Findings The AAIB’s preliminary report outlines a rapid sequence of events on the day of the crash. At 1:13 pm, the aircraft requested pushback and startup clearance, followed by Air Traffic Control (ATC) confirming the need for the full length of Runway 23 at 1:19 pm. Taxi clearance was granted at 1:25 pm, and by 1:33 pm, AI 171 was instructed to line up for takeoff. The flight was cleared for takeoff at 1:37 pm, but just two minutes after liftoff, the pilots issued a MAYDAY call before the aircraft crashed seconds later. The report highlights that both engines shut down within one second of each other after the fuel supply was cut off. Cockpit voice recordings captured one pilot questioning the other about the engine shutdown, with the second pilot denying any action to cut the engines. Examination of the engines recovered from the crash site revealed they were in the “Run” position, and attempts had been made to relight them. RAT Deployment and Technical Analysis Godfrey’s detailed analysis, drawing on the preliminary report, flight data, and airport CCTV footage, revealed that the RAT was automatically deployed at approximately 1:38:47 pm. According to the data, both engines’ N2 values dropped below minimum idle speed at this time, triggering the RAT hydraulic pump to supply hydraulic power. The preliminary report included an image showing the RAT in its extended position but did not clarify the timing or cause of its deployment. By synchronizing multiple data sources—including the flight data recorder (FDR) and ATC logs—Godfrey established that the RAT deployment occurred mere seconds before the crash. This timing strongly suggests a technical malfunction rather than any human intervention. Conflicting Interpretations and Ongoing Investigation Despite Godfrey’s findings, the investigation has been marked by conflicting interpretations. Some experts, including Captain Byron Bailey, have proposed the possibility of deliberate pilot action, even suggesting “suicide by the pilot” as a theory. However, Godfrey’s analysis, supported by the available data, firmly disputes this notion, attributing the crash to a technical failure centered on the RAT deployment. In response to the incident, the U.S. Federal Aviation Administration (FAA) and Boeing reviewed the safety of fuel cutoff switch locks, which had come under scrutiny during the investigation. Both organizations have since affirmed the safety of these components. The investigation into the AI 171 crash remains ongoing, with authorities yet to issue a definitive conclusion. For now, Godfrey’s assessment shifts the focus away from pilot error, underscoring the critical role of the RAT deployment in the tragic sequence of events.

Innovation and Aerodynamics in the Design of the Avro Vulcan’s Wing The Avro Vulcan, colloquially known as the “Tin Triangle,” was far more than a mere delta-wing bomber. Its distinctive shape concealed a host of aerodynamic innovations, rigorous experimentation, and technical refinements that distinguished it during Britain’s postwar advancement of strategic bombers. As a key component of the V-bomber force, the Vulcan embodied a significant leap in aerodynamic science, driven by the pressing Cold War demands for speed, altitude, and survivability. Dr. Steve Liddle, Vulcan to the Sky Trustee and Principal Aerodynamicist at Visa Cash App RB F1 Team, has revisited this critical period in British aviation history through detailed technical reflections. His insights draw upon rare archival materials, including declassified research from the Royal Aircraft Establishment (RAE) at Farnborough during the early 1950s. Pushing the Boundaries of Aerodynamics The Vulcan’s design was fundamentally shaped by the need to surpass and evade increasingly sophisticated enemy defenses. Achieving the required high speeds and altitudes necessitated an unprecedented level of aerodynamic sophistication in bomber design. A central challenge was managing airflow at high subsonic and transonic speeds. Early flight tests involving the Avro 707 and Vulcan prototypes revealed severe buffet caused by shock-induced flow separation, a phenomenon where the wing abruptly lost lift as airflow broke down. To overcome this, engineers at the RAE undertook extensive wind tunnel testing, culminating in the publication of Technical Memoranda 441 in 1955. Under the leadership of aerodynamicist Ken Newby, the research focused on modifications to the Vulcan’s wing leading edge. Three designs were evaluated: a short extension, a long extension, and a curved long extension. The long extension, based on the RAE 101 airfoil, emerged as the most effective, facilitating efficient supersonic airflow expansion and pushing the buffet boundary further back. These refinements, combined with the addition of vortex generators positioned at 25% chord to energize airflow, were ultimately incorporated into production aircraft. Innovation Amid Complexity and Risk The rapid pace of the Vulcan’s development meant that some aircraft were constructed before aerodynamic refinements were fully finalized, reflecting both the urgency and confidence in ongoing research. However, integrating advanced aerodynamic features introduced considerable complexity. Balancing structural integrity and performance while adopting novel solutions presented significant technical risks, and the process was not without controversy. Certain aerodynamic innovations, such as vortex generators, were even tested in flight prior to wind tunnel validation—an approach that would be considered highly unconventional in today’s risk-averse engineering environment. Reactions within the market to such innovation were mixed. While some stakeholders acknowledged the potential for enhanced efficiency and performance, others voiced concerns over increased costs and technical uncertainties. The experiences of contemporaries underscored these risks: for instance, the Gloster Javelin, a Vulcan contemporary, suffered from poor transonic performance due to a less advanced wing design. More recently, companies like Lockheed Martin have encountered significant losses linked to design challenges and performance issues in cutting-edge aviation projects, illustrating the persistent tension between innovation and risk. A Lasting Legacy Despite these challenges, the Vulcan’s refined wing design and buried engines delivered a distinct aerodynamic advantage, ensuring stable and efficient airflow at high speeds. The aircraft’s enduring legacy stands as a testament to the boldness and ingenuity of its designers—engineers who skillfully balanced innovation, risk, and performance to create one of the most iconic bombers of the jet age.
