The National Transportation Safety Board (NTSB) sent a 12-member Go Team to Buffalo, N.Y., today to begin its probe of the Feb. 12 crash of Colgan Air Flight 3407 while on night instrument approach to Buffalo-Niagra International Airport.
According to preliminary accident data, the aircraft, a Bombardier Dash8-Q400 (N200WQ) had departed Newark-Liberty International Airport at about 9:20 p.m. (EST) with 44 passengers and five crewmembers onboard, according to Colgan Air. The regional carrier, a wholly owned subsidiary of Pinnacle, was operating the flight as Continental Connection.
Colgan Air has confirmed the names of crewmembers who were onboard Flight 3407: Captain Marvin Renslow, First Officer Rebecca Shaw, off-duty pilot Joseph Zuffoletto, and Flight Attendants Matilda Quintero and Donna Prisco.
The Q400, powered by two Pratt & Whitney Canada P&W150A turboprop engines, was on approach to Buffalo-Niagra's 8,100-foot Runway 23 when it crashed into a residential neighborhood about 6 miles northeast of the airport, killing all onboard. The aircraft and at least one home were destroyed in the resulting fireball.
At this writing at mid-day Friday, investigators are trying to determine how many people on the ground were killed and if the flight crew had radioed controllers of any problems prior to the accident.
According to FAA data, winds at the time of the accident were from 240 degrees at 15 knots, gusting to 22 knots. There were a few clouds at 1,100 ft., broken clouds at 2,100 ft., and an overcast ceiling at 2,700 ft. The Q400 had about 3 miles visibility while operating in light snow and mist.
Both temperature and dewpoint were 0.6C (33 deg. F.), just above freezing--which indicates that icing may have been a factor. Investigators will be examining all possibilities.
The 74-seat accident aircraft was manufactured and put into service last April, according to Colgan Air. The carrier this month finalized terms for option rights to 15 Q400 NextGen aircraft, which are in addition to its firm order for 15 Q400s placed on Jan. 15.
The Feb. 12 accident was the seventh involving the Dash 8 aircraft type and the second involving a Q400 model. In December 2002, a Changan Airlines Q400 was destroyed when it crashed into a terminal building at Xian-Xianyang Airport, China, while doing an engine runup. There were no fatalities. Since 1988, five other Dash 8s, five -100s and one -300, were involved in accidents that killed 46 people.
A Transportation Safety Board (TSB) of Canada accredited representative will be involved in the NTSB probe, as will technical advisors from the TSB, and aircraft and engine manufacturers, Bombardier and Pratt & Whitney, respectively.
The NTSB's Lorenda Ward is Investigator-in-Charge of the probe, and NTSB Member Steven Chealander is serving as main spokesperson at the on-site investigation.
AviationWeek will continue to report updates as the investigation progresses. See also www.ntsb.gov and www.colgan.com.
