Philippine Airlines flight PR2769 experienced a near-catastrophic altitude excursion near Clark International Airport (CRK) in the Philippines, with Flightradar24 ADS-B data capturing a vertical speed exceeding 11,500 feet per minute during a go-around attempt, followed by a recorded altitude low of 425 feet. The incident occurred amid a significant cluster of cumulonimbus cells directly over and around the airport. Data indicates the aircraft reached approximately 3,500 feet MSL (roughly 3,100 feet AGL) before the extreme descent began, and the altitude loss to 425 feet occurred within a matter of seconds. The lowest recorded ground speed of 64 knots during the sequence is a deeply alarming figure for any commercial transport-category aircraft in a climb or level-flight configuration, pointing strongly toward an aerodynamic stall condition. Unconfirmed reports circulating in aviation communities describe the crew experiencing a stall and a left wing drop, with recovery achieved at extremely low altitude, potentially just feet above terrain or obstacles. Philippine Airlines has confirmed it is investigating the event, and all passengers are reported safe.
The scenario described is consistent with a severe windshear or microburst encounter during the go-around phase, one of the most operationally hazardous combinations in commercial aviation. When an aircraft initiates a missed approach inside the final approach fix, particularly in convective weather, it is in a low-energy, high-drag, transitioning configuration. A microburst at that phase can impose a sudden and overwhelming downdraft that exceeds the aircraft's available climb performance even with maximum thrust applied. A vertical speed exceeding 11,500 fpm — nearly double the descent rate of many emergency descents — is not a figure produced by pilot technique alone; it indicates an external force driving the aircraft toward the ground. The simultaneous reduction in groundspeed toward or below clean stall speed, when combined with a wing drop, strongly suggests the crew encountered not only a severe downdraft but also a large horizontal wind shift that depleted airspeed rapidly and asymmetrically loaded the wings. That a Qatar Airways 787-8 also executed a go-around for windshear at the same airport shortly before and subsequently diverted to Manila confirms that the hazard was widespread and operationally significant, not a localized anomaly.
For flight crews, dispatchers, and operators conducting flights into airports with active convective activity, this incident reinforces several well-established but sometimes underweighted operational principles. Windshear alerts, PIREP reports from preceding aircraft, and real-time radar interpretation must be treated as operationally binding inputs, not advisory ones. A go-around is often perceived as the safe option when the approach becomes unstabilized or unsafe, but in a microburst environment the go-around itself can become the more hazardous event if the missed approach is executed into the core of the convective outflow. The decision to divert rather than attempt an approach when CB cells are overhead the field — as the Qatar crew ultimately did — often reflects better risk management than pressing to land or go-around in deteriorating conditions. Windshear escape maneuver training, which emphasizes maximum thrust, arrest of the descent rate, and trading speed for altitude within aircraft limits, exists precisely for events like this one, and recurrent simulator training remains the only practical environment in which crews can experience and rehearse recovery from these extreme parameters.
The broader significance of this event extends to airport operations, ATC, and meteorological services in regions with pronounced tropical convective weather patterns. Clark International Airport, located in Central Luzon and operating in an environment where intense afternoon and evening convection is routine during certain seasons, presents the same class of convective threat found throughout Southeast Asia, the Pacific, and tropical regions globally. The Philippine aviation authority's investigation will likely focus on crew decision-making during the go-around initiation, onboard windshear detection system alerting and response, ATC weather information dissemination, and any GPWS or TAWS activations during the low-altitude portion of the event. For Part 91, 91K, and 135 operators flying internationally or through convective-prone environments, this incident is a timely reminder that convective avoidance — including avoidance of approaches into fields with active CB cells overhead — is not an inconvenience but a primary safety discipline. The ADS-B data trail left by this flight, showing a descent rate and airspeed profile that should not be survivable, makes the reported safety of the passengers and crew a remarkable outcome and underscores how little margin existed between this incident and an accident.
