Pilots and controllers at San Francisco International Airport (SFO), Memphis International (MEM) and Houston Intercontinental (HOU) may soon take part in operational testing of a new reduced-separation standard between aircraft departing on parallel runways during crosswind conditions. For the wake turbulence mitigation for departures (WTMD) procedure one of the aircraft must weigh more than 300,000 pounds (categorized as “heavy”) and weather conditions must remain at least basic VFR with a 1,000-foot ceiling and three statute miles visibility.
An ATR 72 operated under the Alitalia network by Romanian carrier Carpatair was substantially damaged on February 2 when the crew lost control of the aircraft on landing at Rome Fiumicino Airport in Italy (LIRF). The wind at the time of the accident was approximately 90 degrees to Runway 16, gusting to 41 knots.
Four of the 50 people aboard were injured, two seriously.
More than 500 business aircraft are now using Arinc Direct services in Europe, the Middle East and Asia, and the aeronautical communications and IT specialist is continuing to expand the scope of its support offerings for operators.
The NTSB yesterday placed the primary blame for the 2008 runway excursion of Continental Airlines Flight 1404 in Denver on the captain’s “cessation of rudder input.” The Board determined that the captain needed rudder input to maintain directional control when, about four seconds before departing the runway, the Boeing 737-500 encountered a strong and gusty crosswind “that exceeded the captain’s training and experience.”
Cessna 551 Citation II/SP, Coeur d’Alene, Idaho, Dec. 2, 2007–The Safety Board attributed the landing accident involving the CCM Aviation Citation to the pilot’s failure to maintain aircraft control during landing rollout. The slush-contaminated runway and the crosswind were factors. After the pilot touched down on Runway 23 at Coeur d’Alene Air Terminal, the airplane began hydroplaning to the right.
Cessna Citation Excel 560XL, Port Heiden, Alaska, April 30, 2008–The Excel ran off the gravel-topped Runway 23 at Port Heiden Airport (PTH) as a result of the flying pilot’s failure to maintain directional control while landing in a crosswind, according to the NTSB. The crosswind was a “contributing factor.” There were no injuries among the six occupants.
Bombardier Learjet 35A, Aniak, Alaska, Feb. 21, 2008–The captain of the aero-medical flight whose wing hit the runway inadequately compensated for wind conditions during the landing flare/touchdown, the NTSB concluded. Contributing to the accident were a crosswind and wind shear.
Cessna Citation Excel 560XL, Port Heiden, Alaska, April 30, 2008–The AT&T Alascom Excel was substantially damaged on landing at Port Heiden Airport, but there were no injuries. As soon as the nosewheel touched down, the airplane veered sharply to the left and went off the runway. The left main gear collapsed, and the left wing hit the runway.
Bombardier Learjet 35A, Truckee, Calif., Dec. 28, 2005 – The NTSB blamed the pilot’s inadequate compensation for the gusty crosswind (20 to 30 knots) and failure to maintain an adequate airspeed while making a circling instrument approach and maneuvering in a steep turn close to the ground for the fatal crash of the Learjet 35.
A Raytheon Premier I that ran off the runway on landing at North Las Vegas Airport (VGT) on May 27 might have gotten caught in a wind shift from a crosswind to a quartering tailwind moments before touching down. There were no injuries to the pilot or passenger, but the aircraft was substantially damaged, according to the NTSB’s preliminary report. The airplane touched down on 5,004-foot-long Runway 7 at 3:57 p.m.
