All Four Engines Failed at 37,000 Feet, and the Captain Remained Calm At 37,000 feet above the Indian Ocean, passengers aboard British Airways Flight 9 were abruptly plunged into an unsettling silence. The familiar roar of the Boeing 747’s four engines ceased without warning. There was no turbulence—only an eerie stillness, accompanied by a faint smell of smoke and dimming cabin lights. Anxiety quickly spread through the cabin as passengers grasped the gravity of the situation. In the cockpit, Captain Eric Moody and his crew confronted an extraordinary emergency: all four engines had failed simultaneously. The Incident and the Captain’s Response The 1982 flight, en route from Kuala Lumpur to Perth aboard the Boeing 747 named City of Edinburgh, had unknowingly entered a cloud of volcanic ash emanating from Indonesia’s Mount Galunggung, which had erupted earlier that day. Volcanic ash, invisible to radar and easily mistaken for ordinary cloud, poses a severe hazard to jet engines. Within minutes, the abrasive ash caused all four engines to flame out, transforming the 350-ton aircraft into the heaviest glider in the sky. Captain Moody’s response to the crisis became emblematic of calm leadership under pressure. Over the public address system, he delivered a measured announcement: “Ladies and gentlemen, this is your captain speaking. We have a small problem. All four engines have stopped. We are doing our utmost to get them going again. I trust you are not in too much distress.” His understated tone helped to steady the passengers, some of whom initially believed the message to be a joke, while others gripped their seats in disbelief. Moody’s composure was precisely what the moment required. Navigating a Crisis and Its Aftermath With all engines offline, the 747 began a rapid descent at nearly 2,000 feet per minute. The flight crew calculated they had approximately 23 minutes before reaching the ocean below. Within this narrow timeframe, they faced the daunting tasks of restarting the disabled engines, navigating out of the volcanic ash cloud, managing the aircraft’s structural limits, and reaching a safe altitude with breathable air. Against the odds, after losing nearly 20,000 feet, the crew successfully restarted the engines and executed a safe landing, averting what could have been a catastrophic disaster. The incident not only became a seminal case study in crisis management but also prompted broader discussions about aviation safety. In its aftermath, scrutiny intensified regarding pilot fitness, particularly as the industry grapples with an aging pilot population, with some captains continuing to fly into their eighties. Concerns emerged about the capacity of older pilots to respond effectively to emergencies, while pilot associations struggled to recover from the operational disruptions caused by the Covid-19 pandemic.

Why Aviation Oil Differs from Automotive Oil For many years, pilots and mechanics have questioned why aviation piston engine oils provide less anti-rust and anti-wear protection compared to automotive or heavy-duty engine oils. The explanation lies in the distinct operational demands and stringent regulatory framework governing the aviation industry. Regulatory Standards and Material Compatibility All oils used in certified piston aircraft engines must adhere to the Mil-L-22851 specification, now updated as SAE 1899. This standard guarantees compatibility with every spark-ignition aviation piston engine ever manufactured, emphasizing safety and reliability above all else. Unlike automotive oils, aviation oils are strictly prohibited from containing certain additives, particularly those that produce ash. Automotive and heavy-duty engine oils commonly incorporate ash-forming additives such as zinc dithiophosphate (ZDTP) to enhance anti-wear protection. ZDTP functions by chemically reacting with metal surfaces to form a protective layer, which is especially effective under high shear conditions found between components like cams and lifters. This sacrificial lubrication significantly increases the oil’s load-carrying capacity. However, these additives pose serious risks in aviation engines, many of which contain components made from softer metals such as copper and silver. Copper alloys are frequently used in exhaust valve guides, while silver is often found in master rod bearings of radial engines. ZDTP can tarnish copper, leading to reduced clearances and valve sticking, and it can corrode silver, resulting in bearing failures. Given the critical importance of safety in aviation, such risks are unacceptable. Historical Attempts and Lessons Learned In the 1990s, Phillips Petroleum attempted to improve wear protection in its X/C 20W50 aviation oil by introducing ZDTP, resulting in the X/CII formulation. Because this additive did not comply with the zero-ash requirement, the oil was marketed under a supplemental type certificate (STC). The product was eventually withdrawn after it caused valve sticking and silver bearing failures, underscoring the dangers of applying automotive-style additives in aircraft engines. Detergents and Dispersants in Aviation Oils Another notable difference lies in the use of detergents. While some aviation oils are labeled as “detergent oils,” they are technically ashless dispersant (AD) oils. True detergent oils, common in automotive applications, can loosen and suspend carbon and dirt particles, which may lead to engine fouling in aircraft engines. Therefore, aviation oils avoid such formulations to maintain engine cleanliness and reliability. Industry Challenges and Market Dynamics Aviation engines operate under higher temperatures and pressures than their automotive counterparts, necessitating specialized oil formulations. The aviation sector is also subject to more rigorous regulatory standards and safety requirements, which translate into stringent testing and approval processes for lubricants. These factors contribute to the demand for specialized aviation oils, often resulting in higher costs and intensified competition among manufacturers. In response, oil companies invest heavily in proprietary formulations designed not only to meet or exceed aviation standards but also to improve cost-efficiency and environmental sustainability. Conclusion Although aviation oils may appear to offer less anti-wear and anti-rust protection than automotive oils, these differences are fundamentally driven by the unique materials, operating conditions, and uncompromising safety standards of the aviation industry. Consequently, significant changes to aviation oil formulations remain unlikely, ensuring continued reliability and safety in flight operations.

Cowling Detaches in Flight and Strikes Windshield A Piper PA-28-180 encountered a mid-flight mechanical failure when the right side of its engine upper cowling became unlatched and struck the windshield during cruise between airports. Despite the left side of the cowling remaining secured, the incident caused substantial damage to the windshield. The pilot was able to maintain control and safely land the aircraft at an airport in Mesa, Arizona. Fortunately, no injuries were reported. Investigation and Findings A post-incident examination determined that the right front fastener pin, responsible for securing the upper cowling near the air intake, had separated from the cowling structure. This separation likely allowed the forward right side of the cowling to detach from the lower section and lift into the airstream. The resulting aerodynamic forces caused the right side latches to fail under overload. The National Transportation Safety Board (NTSB) identified the probable cause as the failure of the engine cowling’s right side latch pin and fasteners, which led to the partial separation of the cowling during flight. This event, documented under NTSB Identification 193480, underscores the critical importance of thorough pre-flight inspections and the secure fastening of engine components.
