The U.S. National Transportation Safety Board (NTSB) has issued its preliminary report about an incident at Denver last week involving an Airbus A319 aircraft, operated by Air Canada. Judging from the description of events provided by the NTSB, it sounds as though the crew had one very frustrating afternoon.
The aircraft (registration number C-FYJP), operating as Air Canada Flight ACA1042, was departing Denver International Airport for a scheduled passenger flight to Toronto's Pearson International Airport on the afternoon of July 23, 2008. According to the NTSB report, the captain heard a "whistling noise" during the takeoff roll. Suspecting an unsecured window, he rejected the takeoff. The aircraft taxied back and a second takeoff was initiated.
Here's what happened next (quoting from the NTSB report):
Gear retraction, which was delayed to allow the brakes to cool as a result of the previous rejected takeoff, was normal.There were no injuries reported among the two cockpit crew, three flight attendants, and 94 passengers on board at the time of the incident.
When the flaps were retracted, an F-LOCKED message was received. An emergency was declared.
When the airplane was configured for landing, the following messages were illuminated: RIGHT UNLK ON PANEL; L/G DISAGREE; L/G NOT DOWN. A go-around was made and dispatch and maintenance were contacted.
It was later determined that the landing gear was down and locked, and a flaps 3 landing was made on runway 16R. There was a noticeable vibration on the right side of the airplane, and minimal braking was used to slow the airplane on the 16,000-foot runway. Inspection revealed the right inboard tire had failed.
After discussions with the cabin crew and some passengers, indications were that the tire failed at rotation on the second takeoff. Rubber fragments were found on the right side of the runway at the 6,000-foot mark.
Sounds like that airplane just didn't want to leave Denver!
