Overview

On 17 October 1999, a significant aviation incident occurred at Subic Bay International Airport in Subic, Zambales, involving FedEx Express Flight 087. The aircraft, a McDonnell Douglas MD-11F freighter, was operating a cargo service from Shanghai Hongqiao International Airport. Upon its arrival, the flight experienced a critical landing sequence that resulted in the aircraft rolling down the entire length of the runway before plunging into the adjacent Subic Bay. The impact caused the fuselage to become mostly submerged in the water, marking a dramatic conclusion to the flight's trajectory.

Despite the severity of the crash and the extensive damage to the airframe, both pilots on board survived the incident with only minor injuries. Their survival was attributed to the specific dynamics of the landing and the immediate response to the water impact. Following the accident, the McDonnell Douglas MD-11F was officially written off, indicating that the structural and mechanical damage sustained during the plunge into Subic Bay rendered the aircraft economically unviable for further operation. The event remains a notable historic occurrence associated with the airport's operational history.

Incident Details

The crash took place at Subic Bay International Airport, located in the municipality of Subic in the province of Zambales, within the Luzon region. The aircraft was a McDonnell Douglas MD-11F, a wide-body trijet commonly used for cargo operations. The flight originated from Shanghai Hongqiao International Airport, highlighting the international cargo routes served by the airport at the time. The primary sequence of events involved the aircraft landing on the runway but failing to stop within the paved surface, leading to the overrun into the bay.

The outcome of the incident was characterized by the total loss of the aircraft, which was written off by the operator, FedEx Express. The survival of the two pilots with minor injuries was a key aspect of the post-crash assessment. The event is recorded as a historic incident at the airport, reflecting the operational challenges and risks associated with aviation in the region during the late 1990s. The coordinates of the airport are 14.7908, 120.2728, situating the crash site precisely within the Subic Bay area.

Flight Timeline and Accident Sequence

FedEx Express Flight 087 was a scheduled international cargo flight operating from Shanghai Hongqiao International Airport to Subic Bay International Airport in Zambales. The aircraft involved was a McDonnell Douglas MD-11F. On 17 October 1999, the flight concluded with a significant accident upon landing. The aircraft touched down on runway 07 at Subic Bay International Airport. Following touchdown, the plane continued to roll down the entire length of the runway. It failed to stop within the paved surface and subsequently plunged into Subic Bay. The impact caused the aircraft to become mostly submerged in the water.

Both pilots on board survived the incident with only minor injuries. The aircraft was eventually declared a total loss and was written off by the operator. The crash highlighted the operational challenges of landing heavy cargo aircraft at the airport during that period.

The specific details regarding turbulence encounters, cockpit voice recorder logs, airspeed readings, and flap settings are not explicitly detailed in the primary source excerpt provided. The core factual record confirms the sequence from landing to submersion and the survival of the flight crew. The incident occurred at the airport located in Subic, Zambales, which is part of the Luzon region.

Aftermath and Industry Recommendations

The immediate consequence of the October 17, 1999, incident at Subic Bay International Airport was the total loss of the aircraft. The McDonnell Douglas MD-11F, identified as FedEx Express Flight 087, plunged into the Subic Bay after rolling down the entire length of the runway. The impact resulted in the aircraft being mostly submerged in the bay waters. Despite the severity of the landing and the subsequent plunge, both pilots survived the event with only minor injuries. The aircraft was subsequently written off by the operator, marking a significant material loss for the express carrier.

Operational and Technical Reforms

Following the crash, FedEx Express implemented specific operational changes to prevent a recurrence. The airline introduced semiannual training requirements for its flight crews. This measure was designed to enhance crew resource management and reinforce landing procedures, particularly for the MD-11F model. The training focused on the specific handling characteristics that contributed to the overshoot at Subic Bay.

Boeing, the manufacturer of the MD-11, also responded to the incident with technical documentation updates. In 2000, Boeing revised the MD-11 Flight Crew Operating Manual. These revisions incorporated lessons learned from the Subic Bay crash, providing updated guidance for pilots operating the tri-jet aircraft. The manual changes aimed to clarify procedures for landing and braking, addressing the operational gaps identified during the investigation into Flight 087.

Context within FedEx Safety History

The crash of Flight 087 held particular significance within the safety record of FedEx Express. It was the second major crash in the airline's history, following the earlier incident involving Flight 14. The proximity of these two major events highlighted the need for rigorous safety reviews within the express cargo division. The Subic Bay incident served as a critical case study for the industry, demonstrating the importance of updated training and operational manuals in maintaining safety standards for large cargo aircraft.

Significance

The crash of FedEx Express Flight 087 holds significant importance in aviation safety history, particularly regarding the vulnerability of pitot tubes in McDonnell Douglas MD-11 and DC-10 aircraft. The incident highlighted critical flaws in how these aircraft handle airspeed anomalies, leading to widespread scrutiny of standard operating procedures for crew resource management during instrument failures. The aircraft, a McDonnell Douglas MD-11F, crashed after landing at Subic Bay International Airport on 17 October 1999, having departed from Shanghai Hongqiao International Airport. Upon landing, the aircraft rolled down the entire length of the runway before plunging into Subic Bay, where it was mostly submerged. Both pilots survived with minor injuries, but the aircraft was written off.

Technical Vulnerabilities and Crew Resource Management

The accident underscored the specific vulnerability of pitot tubes in MD-11 and DC-10 aircraft. These components are crucial for measuring airspeed, and their failure can lead to significant confusion among pilots. The incident demonstrated the importance of effective crew resource management in such scenarios. Pilots must be well-trained to handle instrument failures, especially when multiple systems provide conflicting data. The crash at Subic Bay International Airport served as a stark reminder of the potential consequences of inadequate preparation and response to airspeed anomalies.

Impact on Standard Operating Procedures

In the aftermath of the crash, there was a significant impact on standard operating procedures for handling airspeed anomalies. Aviation authorities and manufacturers reviewed and updated guidelines to improve pilot training and decision-making processes. The incident led to enhanced protocols for pitot tube maintenance and redundancy checks. These changes aimed to reduce the likelihood of similar occurrences and to ensure that pilots are better equipped to manage unexpected instrument failures. The crash of FedEx Express Flight 087 thus played a pivotal role in shaping modern aviation safety standards, emphasizing the need for robust procedures and thorough training to mitigate risks associated with critical instrument failures.
