2006 New York City plane crash

A Cirrus SR20 similar to the aircraft involved in the incident

The aircraft departed from Teterboro Airport in Teterboro, New Jersey, at 2:29 pm EDT (18:29 UTC). Lidle planned to fly to Nashville, Tennessee, where he had a hotel room booked for the night,[11] then to Dallas, Texas, and finally on to his home in California.[1][12][13]

Radar measurements show that, immediately before the crash, Lidle's aircraft was flying at 112 mph (180 km/h) at 700 feet (210 m) altitude[14] in the East River VFR corridor, an area which former NTSB official Peter Goelz described as "very tricky" due to its narrow width and frequent congestion.[15][16] The VFR corridor ends abruptly at the northern tip of Roosevelt Island. Aircraft must receive an air traffic control clearance to proceed beyond the boundaries of the corridor, or else make a sharp U-turn and return the way they came. Lidle's plane flew north along the corridor almost to the end before executing a turn and hitting the north face of the building along the river.[16]

The airplane struck the Belaire, a 42-story condominium tower at 524 East 72nd Street,[17] at approximately 30 stories above the ground.[18] The plane hit the apartment owned by Dr. Parviz Benhuri and his wife Ilana,[8] the latter of whom was seated in the room when the plane crashed and sustained shrapnel injuries and burns. Her housekeeper was also present and helped her escape.[19]

The aircraft's Ballistic Recovery Systems emergency parachute, designed to bring the small plane down safely from altitudes above 500 ft, was not deployed.[20] The plane circled the Statue of Liberty before flying north up the East River and disappeared from radar near the Queensboro Bridge. It was flying under visual flight rules (VFR) and had attracted no special attention from air traffic controllers or NORAD before the crash. The aircraft took a hard U-shaped turn before it hit the building.[21]

In an interview Lidle gave about a month earlier, he stated he had been a pilot for seven months and had flown about 95 solo hours.[22] The crash garnered extra attention because of superficial similarities to the September 11 attacks in New York City, which had occurred five years earlier. U.S. officials said that NORAD scrambled fighter aircraft over numerous American and Canadian cities for Combat Air Patrol,[23] and that U.S. President George W. Bush was informed about the situation, but that these were precautionary measures only.[24] The FBI quickly announced there was no reason to suspect that the crash was an act of terrorism.[25]

LaGuardia Airport and John F. Kennedy International Airport did not experience delays from the crash. Police cordoned off several blocks at the peak of the confusion, but subway and NY Waterway ferry services continued without interruption. The FAA initially imposed a temporary flight restriction on an area within one nautical mile (1.9 km) of the scene, from ground level to 1,500 feet (460 m) altitude.[26] This restriction was lifted the next day, though New York Governor George Pataki called for permanent restrictions.[16]

On October 13, 2006, two days after the crash, the FAA banned all fixed-winged aircraft from the East River corridor unless in contact with local air traffic control. The new rule, which took effect immediately, required all small aircraft (with the exception of helicopters and certain seaplanes) to seek the approval of and stay in contact with air traffic control while in the corridor. The FAA cited safety concerns, especially unpredictable winds from between buildings, as the reason for the change.[14]

On October 11, the National Transportation Safety Board dispatched a six-member "Go Team" from Washington, D.C. to New York City,[27] which arrived at the scene in the evening to take fuel samples and examine clues found in the debris. These included the aircraft's bent propeller, a charred memory chip, the undeployed parachute,[28] and Lidle's flight log book.[29]

The NTSB's final hearing on May 1, 2007, determined that "the pilots' inadequate planning, judgment, and airmanship in the performance of a 180-degree turn maneuver inside of a limited turning space" caused the crash.[30] The investigation was unable to determine whether Lidle or his flight instructor was at the controls. Although there was 2,100 feet (640 m) of space available, the aircraft used only about 1,700 feet (520 m) of width in which to make the 180-degree turn—but this distance was effectively reduced to 1,300 feet (400 m) by the 13-knot (24 km/h) easterly winds that day. A bank angle of at least 53 degrees would be required to successfully execute a 180-degree turn in this distance. If the required bank was not initiated early then, as the turn progressed, the bank angle would have needed to have been increased, possibly resulting in an aerodynamic stall. The investigation was unable to determine if the plane stalled at the time of the crash. An animation of the flight path combining radar data with a Coast Guard video of the East River was also presented.[10][31][32][33]

A lawsuit brought by Lidle's family against the manufacturer of the aircraft, Cirrus Design, alleging a mechanical defect, was rejected by a jury in May 2011.[34]
