United Airlines captain dies after suffering heart attack during flight

26 September 2013, United Airlines; 737-900; flight 1603; near Boise, ID: A United Airlines captain suffered a heart attack while en route on a scheduled flight from Houston, TX to Seattle, WA. Although the captain received prompt treatment while in flight and after the aircraft made an unscheduled landing in Boise, ID, he was pronounced dead after arriving at a local hospital. The flight later continued onward to Seattle with a replacement pilot.

According to several media reports, after the 63-year-old pilot was stricken, two passengers, both military physicians stationed in Washington State, attended to the pilot, and the remaining pilot, as well as an off-duty United pilot who was also on board, made an emergency landing in Boise, ID. An autopsy performed the following day confirmed that the pilot had died of a heart attack.

Selected previous events
This was not the first time that an airline pilot was incapacitated during a flight. The following are just some of the more recent events:

• 20 January 2012 - A 44-year-old reserve first officer of a UTair 757 suffered a heart attack while en route from Chengdu, China to Novosibirsk, Russia. Although the pilot received prompt medical attention, including help from a passenger who was a cardiologist, the pilot died before the crew could make an emergency landing. The pilot was in the cockpit, but not at the controls, when he suffered a heart attack. In April of that same year, a UTair ATR72 crashed in Russia, killing dozens of passengers.


• 14 October 2010 - The 43-year-old captain of a Qatar Airways A330-300 suffered a massive heart attack roughly an hour after takeoff during a flight from Manila to Doha, Qatar. The first officer diverted the aircraft to Kuala Lumpur, where the pilot was pronounced dead after the plane arrived.


• 14 June 2010 - About an hour into a flight from San Francisco to Chicago, the first officer of an American Airlines 767 felt ill and was unable to continue with his flying duties. There were no off-duty pilots on board, and the captain chose to have a flight attendant with several hundred hours of flight experience provide assistance for the remainder of the flight.


• 18 June 2009 - The captain of a Continental Airlines 777-200 died while en route from Brussels, Belgium to Newark, NJ. The 60-year-old captain was replaced by a reserve first officer and the crew declared an emergency. The aircraft landed without further incident.


• 28 January 2008 - The first officer of an Air Canada 767 on a scheduled flight from Toronto to London became mentally incapacitated and the captain needed he help of several flight attendants to physically remove the first officer from the cockpit. The captain, along with the help of a flight attendant who held a commercial multiengine license, diverted the aircraft to Shannon, Ireland.

How frequent are these events?Y
While accidents involving serious injury or death to pilots or crew are routinely reported to civil aviation authorities around the world, deaths, injuries, or incapacitations due to natural causes are not. While there are many media reports of such incidents, especially in recent years with the increased use of social media, there are few formal studies of incidents of pilot incapacitations. One of them is a 2004 study from the FAA's Civil Aerospace Medical Institue, which found that in the six-year period from 1993 and 1998 there were 39 cases where a U.S. airline flight crew member was unable to perform any flight duties and 11 cases where the flight crew member was impaired and could only perform limited flight duties.

These 50 cases occurred on 47 different flights (two crew members were affected on three of the 47 flight). Four of these events involved a crew member death, all due to cardiac arrest. According to the FAA, in seven of these events the safety of the flight was seriously affected:

1. A 737 first officer experienced an alcohol-withdrawal seizure, applied full right rudder, and slumped over the control wheel, causing a loss of altitude until flight attendants could pull the first officer off the controls.


2. The foot of a DC9 first officer became lodged against a rudder pedal after his leg stiffened during a heart attack. The captain applied opposite rudder until the first officer's foot could be dislodged.


3. The flight engineer and the captain of a 727 lost consciousness after the flight engineer accidentally depressurized the aircraft. The first officer donned an oxygen mask and made an emergency descent.


4. A captain suffered an epileptic seizure while the aircraft was taxiing and applied enough force to the rudder to cause the aircraft to turn sharply and stop. The first officer removed the captain from the controls and taxied back to the gate.


5. An A300 captain suffered a cerebral infarction during approach, and neglected to lower the landing gear. After landing, the captain applied reverse thrust longer than necessary, and attempted to apply takeoff thrust on the taxiway.


6. An MD88 Delta Airlines captain, who was using unapproved contact lenses, misjudged his approach a LaGuardia Airport on 19 October 1996 during conditions of reduced visibility and struck approach lights near the end of the runway. The aircraft was substantially damaged, and three passengers received minor injuries during the evacuation.


7. The captain and first officer of a DC8 cargo flight both had their judgement affected due to fatigue, and they allowed the aircraft to enter an unrecoverable approach stall while on a approach to the airbase at Guantanamo Bay in Cuba. The captain, first officer, and flight engineer were all seriously injured in the 18 August 1993 crash.

Flight Attendant Fills in for Sick Pilot

On Monday June 14, 2010, the first officer on American Airlines flight 1612, a Boeing 767 flying nonstop from San Francisco to Chicago with 225 passengers and a crew of seven, became ill about an hour into the flight and was unable to continue with his flying duties. After the captain, Jim Hunter, deemed the first officer too ill to fly, the flight's purser reviewed the passenger list for off-duty pilots, but none were on board. It turns out that two of the cabin crew members, the purser and flight attendant Patti Deluna, both had flying experience, the captain chose Deluna because she had more flying experience. She earned a commercial license in 1970 and has logged about 300 flight hours.

According to an American Airlines spokesperson, Deluna read checklist procedures to the captain as he configured the aircraft for landing, in addition to handling other tasks in the cockpit. She was in the cockpit for about the last 90 minutes of the flight.

The plane, carrying 225 passengers and seven crew members, landed safely at Chicago's O'Hare airport, at 4:24 p.m. Monday. After the aircraft landed, the first officer was taken to a local hospital where he was treated and released the next day.

Previous 767 Incapacitated Pilot Incident
This is not the first time that a flight attendant has taken over for an incapacitated pilot. In January 2008, the first officer on an Air Canada 767 on a flight from Toronto to London became incapacitated and had to be removed from the cockpit. The captain declared an emergency and completed the flight with the assistance of a flight attendant who was also a licensed pilot.

Continental Airlines Captain Dies During Transatlantic Flight

The captain of Continental Airlines Flight 61, a 777 en route from Brussels to Newark, died while the aircraft was in flight over the Atlantic. The captain was replaced by a reserve first officer and the crew declared an emergency. The aircraft landed without further incident. There were 247 passengers on board, and there were no other injuries to passengers or crew.

Early reports indicate that the captain, who apparently died of natural causes, was removed from the cockpit and placed in the crew rest area. The airline stated that the crew of this flight included the captain and two first officers, this extra flight crew member is required by the FAA for longer flights such as this one.

The airline reported that the captain was 60 years old and had been with the airline for 32 years. Coincidentally the FAA changed the rules in December 2007 to raise the mandatory retirement age from 60 to 65 to fly large passenger aircraft. This rule change was consistent with a 2006 ICAO regulation change that also changed the mandatory retirement age to 65.

This is the third safety related event in the last 12 months for Continental. In December 2008, Continental Flight 1404 crashed in on takeoff in Denver and was destroyed by fire. None of the passengers or crew were seriously injured. In February 2009, Continental Connection Flight 3407 crashed near Buffalo during approach, killing all 49 passengers and crew members, as well as one person on the ground. The last significant safety event for the 777 was a January 2008 crash of British Airways Flight 38 in London. None of the 16 crew members or 136 passengers were killed.

Flight crew members dying or becoming incapacitated in flight are rare events. One recent incident of note was another transatlantic flight, this one a January 2008 Air Canada 767 flight from Toronto to London where the first officer had to be physically removed from the aircraft due to erratic behavior.

Note: An earlier version of this post mistakenly identified the incapacitated Air Canada flight crew member as the captain.

What an Air Canada Event Says About Incapacitated Pilots

AirSafe.com reviews the investigation into a January 2008 incident where an Air Canada pilot became mentally incapacitated and had to be removed from the cockpit. Once the first officer was removed, the captain was able to safely land the aircraft. The event caused some in the aviation community to question whether this kind of incident may have led to serious problems in the past. While a review of the available incident and accident record by AirSafe.com revealed no proven cases of a mentally incapacitated pilot deliberately causing death or serious injury to passengers, there have been several cases where such behavior was suspected, and one case where a pilot crashed an airliner on purpose.

On 19 November 2008, the Air Accident Investigation Unit of the Irish Department of Transport released their incident report on a 28 January 2008 event involving an Air Canada flight. The captain declared an emergency and diverted to Shannon, Ireland due to the incapacitation of a flight crew member.

The Air Canada 767 was on a scheduled flight from Toronto to London and carried 146 passengers and nine crew members. After the first officer became incapacitated, the captain declared an emergency and completed the flight with the assistance of a flight attendant who was also a licensed pilot.

According to the incident report, the first officer had arrived late for his flight, with the captain having already completed all preflight preparations before the first officer's arrival.

During the early phases of the flight, the first officer left the flight deck several times for short periods, and made it clear to the captain that he was tired.

At one point, the captain allowed the first officer to take a controlled rest break in cockpit. Over an hour later, as the aircraft was near the midpoint of its ocean leg, the first officer began to display unusual behavior, including rambling and disjointed conversation.

The first officer left the cockpit again, and after he returned he didn't follow proper cockpit reentry procedures, and also neglected to fasten his seat belt. It became apparent to the captain that the first officer was suffering from an unknown medical condition which impaired his ability to carry out his required duties on the flight deck. The captain summoned the lead flight attendant to get the first officer removed from the cockpit. The lead flight attendant removed the first officer with the help of other flight attendants. One of those flight attendants sustained a wrist injury during the removal.

After the removal of the first officer, the captain had the lead flight attendant check to see if there were any flight crew members among the passengers. None were on board, but one of the flight attendants held a commercial multiengine license, and she assisted the captain as the flight diverted to Shannon, Ireland.

The first officer was hospitalized in Ireland for 11 days before being transferred by air ambulance back to Canada for further treatment.

News reports about this incident focused on the more dramatic elements of the event, such as what the first officer said after being removed from the cockpit, or how and where the first officer was restrained in the cabin. However, this incident raised more serious issues in the minds of many passengers, such as whether the mental state of a pilot should be a concern, or whether a mentally unstable flight crew member has ever caused serious injuries or deaths to airline passengers.

AirSafe.com not aware of any reliable, publicly available information about the number of pilots in the US or elsewhere who have been removed from flight status due to some kind of psychological or psychiatric issue.

The information is more clear when it comes to cases where an airliner crashed as a result of deliberate flight crew actions. Quite simply, there are no proven events where an airline pilot's deliberate actions or mental state led to the deaths of one or more passengers. Correction (28 March 2012) - On February 1968, 24 passengers were killed in the crash of a JAL DC8 in Tokyo after the the captain deliberately disengaged the autopilot and flew the aircraft into Tokyo bay. All of the crew members survived, but 24 of the 166 passengers were killed. It was later reported that the captain had been suffering from schizophrenia.

There has been at least one case of a pilot deliberately crashing an airliner.
On 11 October 1999, an Air Botswana pilot, who had been grounded for medical reasons, took off alone in an Air Botswana ATR42 airliner, and crashed it into two of the airline's other ATR42s on the ground. Fortunately, there was no one else in the other two aircraft. The pilot was the only person killed in this event.

There were two other crashes that many in the aviation community suspected were caused by pilot actions, but investigative authorities found no conclusive evidence that they were deliberately caused by one of the pilots. On 31 October 1999, an EgyptAir 767 en route from New York to Cairo, crashed in the Atlantic, killing all 217 on board. The NTSB concluded that the airplane's departure from normal cruise flight and subsequent impact with the Atlantic Ocean was a result of the first officer's flight control inputs, but could not determine a reason for the first officer's actions.

On 17 December 1997, a SilkAir 737, traveling between Jakarta and Singapore, crashed into a river, killing all 104 people on board. While there was ample evidence that the captain was under great personal stress, and indications that both the cockpit voice recorder and flight data recorder were turned off prior to the crash, there was no evidence that either pilot deliberately brought the aircraft down.

These past events, as well as the most recent event involving Air Canada, remind the public that while there's always a possibility that a pilot would deliberately put passengers or aircraft at risk, there have been no passenger deaths or serious injuries associated with incidents where such behavior was proven.
