Colgan Air Three Four Oh Seven, the Stick Shaker That Fired Over Buffalo, and the Wrong Response That Changed How America Trains Airline Pilots

On February 12, 2009, a Bombardier Dash 8 Q400 operating as Colgan Air Flight 3407 crashed into a house in Clarence Center, New York, killing all 49 people aboard and one person on the ground. It remains the deadliest aviation accident on U.S. soil since 2001. The investigation that followed exposed systemic failures in pilot training, rest regulations, and hiring practices that reshaped how this country qualifies the people sitting in regional airline cockpits.

What Happened on Approach to Buffalo

Flight 3407 was a Continental Connection regional service from Newark Liberty International Airport to Buffalo Niagara International Airport. The aircraft departed Newark at 9:41 PM. Flight time was approximately 45 minutes.

The crew had been paired together for less than two days. Captain Marvin Renslow, 47, had been with Colgan Air since 2005. First Officer Rebecca Shaw, 24, had joined the carrier eight months earlier. Shaw earned approximately $16,000 per year and had relocated to Seattle to live with her parents, commuting cross-country to Newark to work. The NTSB would later estimate she had been awake for approximately 36 hours by the time the flight departed.

Outside the aircraft, ice was accumulating. The crew had the de-icing and pneumatic boot systems activated. What they did not have was full situational awareness of a gradual, dangerous airspeed decay.

The Sterile Cockpit Violation

Federal regulations require crews to restrict conversation to duties essential to the safe operation of the aircraft below 10,000 feet. This is the sterile cockpit rule, and it exists because distraction on approach has killed people.

The NTSB’s investigation found the crew spent significant portions of the descent into Buffalo in personal conversation - Shaw’s first winter in Seattle, Renslow’s girlfriend, regional flying life. The aircraft was providing them information through its instruments. They were not fully processing it.

The Stick Shaker Fires at 2,300 Feet

At approximately 2,300 feet on the approach, the stick shaker activated.

The stick shaker is not an advisory alert. It physically vibrates the control column. It fires when the aircraft’s angle of attack has reached a critical threshold - the edge of an aerodynamic stall. The trained response on a Dash 8 Q400 is immediate: push the nose forward, advance power levers to maximum, retract drag, climb. That response is rehearsed until it is reflexive.

Captain Renslow pulled back.

His response - raising the nose while the stick shaker was firing - increased the angle of attack. The system escalated to the stick pusher, a secondary device that physically forces the nose down to prevent a full stall. Renslow countered the stick pusher with back pressure. He fought the system designed to save the aircraft.

The Dash 8 stalled. It rolled left, then right. The nose pitched up violently. At the same moment, First Officer Shaw deployed flaps to 45 degrees - an enormous drag increase at the worst possible moment, apparently a reflexive response to what her brain processed as an overspeed situation.

The aircraft impacted a house on Long Street in Clarence Center, New York, at approximately 10:17 PM. There was no survivable space.

What the NTSB Investigation Found

The NTSB’s probable cause was Renslow’s inappropriate response to the stick shaker activation. But the board made clear the stick shaker was not a random event. It was the last alarm in a chain of warnings the crew had not fully processed.

The board found Renslow had completed required stall recognition training in the simulator. What he had not practiced sufficiently was full stall recovery in conditions resembling an actual emergency - icing, fatigue, low altitude, everything at once. Simulator training in that era often focused on recognizing the onset of a stall and recovering before full aerodynamic stall developed. Full stalls were not always required in the training sequence.

Under real stress, in the dark, surprised and fatigued, his hands did what untrained hands do. They pulled.

The board also found the existing rest regulations were structurally inadequate for the commuting patterns that had become standard in regional aviation. Shaw was not an outlier. Thousands of regional first officers were commuting long distances and reporting for duty fatigued because the rules governed duty time - not the moment a pilot left home. That was industry practice.

Additionally, Renslow had failed five check rides across his career, including at Colgan itself. When hired, he had signed paperwork indicating he had no failed check rides. That information was not in his public file. His passengers had no way of knowing.

How the Crash Rewrote Airline Pilot Certification

Congress moved unusually quickly. The Airline Safety and Federal Aviation Administration Extension Act of 2010 made sweeping changes to pilot certification standards.

The most debated provision was the 1,500-hour rule. Before the legislation, a regional airline first officer could fly passengers under a commercial pilot certificate, which requires just 250 total flight hours. The new law required all Part 121 first officers to hold an Airline Transport Pilot (ATP) certificate, which requires 1,500 total hours, specific instrument and cross-country experience, and a significantly more demanding knowledge and practical test.

The rule narrowed the pipeline into the airlines and contributed to the regional pilot shortage that defined the following decade. Critics have argued it addressed a symptom rather than a root cause - that hours alone do not guarantee the kind of response-under-pressure the accident revealed was missing. Those arguments have merit.

What the rule undeniably did was raise the minimum floor under every regional cockpit in America.

The law also created new requirements for pilot training record disclosure between employers. Renslow’s check ride failures would have been visible to Colgan under the new framework. And the revised rest rules drew a harder line around commuting patterns that the previous regulations had not addressed.

Why This Matters if You Fly Anything With an Engine

Stall recovery is not reflexive by default. It is trained into you, or it isn’t.

The human brain, presented with an aircraft that is pitching up and shaking, wants to pull. It wants to bring the nose up, maintain altitude, preserve the visual picture. That instinct is wrong. At low altitude on approach, it is fatal.

The correct response - reduce angle of attack, add power, pick up the wings - must be built to the level of automaticity. Not understood. Not checked off a knowledge list. Automatic. The kind that fires before the thinking brain has time to override it with instinct.

That means practicing full stalls, not just the approaching buffet. It means recovering with flaps deployed, in turns, at different power settings - in conditions that approximate the actual aerodynamic event, not just its warning signs.

Renslow knew the correct response in the abstract. He had been tested on it. Under real conditions, it did not fire in time. When the stick shaker fires on approach at 2,300 feet, the wing is approaching the edge. There is no nuanced interpretation.

Push. Power. Wings level.

Key Takeaways

Colgan Air Flight 3407 crashed on February 12, 2009, killing 50 people - the deadliest U.S. aviation accident since 2001 - after the captain responded incorrectly to a stick shaker activation on approach to Buffalo.
The NTSB cited the captain’s inappropriate stick pusher counter-response as probable cause, with contributing factors including fatigue, sterile cockpit violations, inadequate stall training, and a hiring system that concealed the captain’s five failed check rides.
First Officer Shaw had been awake approximately 36 hours before the flight; existing FAA rest rules at the time said nothing about cross-country commutes to reach a domicile.
The Airline Safety and FAA Extension Act of 2010 raised the minimum requirement for Part 121 first officers from a 250-hour commercial certificate to a 1,500-hour ATP certificate and created mandatory training record disclosure between employers.
Stall recovery must be practiced to the point of automaticity - full stalls, in realistic configurations, not just stick shaker recognition - because the instinctive response under surprise and fatigue is to pull, which is exactly wrong.
