On April 2, 2005, about 1717 eastern standard time, N169TA, a Canadair CL-600-2A12, was substantially damaged during landing at the Teterboro Airport (TEB), Teterboro, New Jersey. The two certificated airline transport pilots, and two passengers were not injured. Instrument meteorological conditions prevailed for the executive transport flight that departed Dallas Love Field Airport (DAL), Dallas, Texas, destined for the Teterboro Airport. An instrument flight rules flight plan was filed and activated for the flight conducted under 14 CFR Part 91. According to the captain, the airplane departed Love Field, climbed to Flight Level 370, and cruised to the New Jersey area without incident. The airplane held about 35 miles west of the Teterboro Airport for approximately 40 minutes, before being vectored onto the final approach course for the ILS Runway 19 Approach. The captain configured the airplane to land, and flew the final segment of the approach at Vref plus 30 knots because of turbulence and reported wind gusts. As the captain initiated a flare to land on runway 19, the airplane encountered windsheer. It touched down hard on the main landing gear, bounced, and then touched down again on the nose wheel. The captain stabilized the airplane, slowed to taxi speed, and exited the runway. Once clear of the active, maintenance inspected the airplane for damage. The nose gear was then "blocked," and the airplane towed to a hangar. The captain added that during the en route and arrival phases of the flight, he periodically checked the weather via a data uplink, and was aware of the current weather conditions. According to the operator, examination of the airplane revealed damage to the right wingtip, right outboard flap jackscrew cover, and the pressure bulkhead in the vicinity of the nose gear box. A weather observation taken at the Teterboro Airport, 26 minutes prior to the accident, recorded the following: wind 150 degrees at 26 knots, gusting to 37 knots; visibility 1 mile in heavy rain and drizzle; broken clouds at 1,500 feet; overcast clouds at 2,400 feet; temperature 55 degrees Fahrenheit; dew point 54 degrees Fahrenheit; and an altimeter setting of 29.35 inches of mercury.
