A faulty component and the crew's inadequate response caused an AirAsia A320 to crash into the Java Sea last year, killing all 162 people on board, according to an Indonesian report.

The pilots' failure to correctly respond to a recurring rudder problem led to the crash of an AirAsia commercial jet<span style="color: Red;">*</span>into the Java Sea a year ago, killing all 162 aboard, Indonesian safety officials said Tuesday.
AirAsia Flight 8501 disappeared from radar screens Dec. 28 about 40 minutes out of<span style="color: Red;">*</span>Surabaya, Indonesia,<span style="color: Red;">*</span>bound for Singapore in stormy weather.<span style="color: Red;">*</span>Indonesia's National Transportation Safety Committee issued a report saying a rudder control system on the Airbus A320 had failed almost two dozen times in the year before the crash.
"The degraded performance and ambiguous commands might have decreased the SIC's (co-pilot) situational awareness and he did not react appropriately in this complex emergency resulting in the aircraft becoming upset," the report said.
Airbus, the plane's manufacturer, said in a statement Tuesday that the company is studying the report, to which it contributed technical expertise.
"We are now carefully studying its content," the statement said.<span style="color: Red;">*</span> "With safety being top priority, Airbus is fully committed to push the safety track record of our industry even further."
The co-pilot, Rémi-Emmanuel Plesel, had 2,275 flying hours with AirAsia. Captain Iriyanto had more than 20,000 flying hours.
Australian, French, Singaporean and Malaysian authorities took part in the investigation. Maintenance records indicated the rudder problem's frequency had been increasing, and the malfunction, caused by a cracked joint on a circuit board,<span style="color: Red;">*</span>occurred nine times in December.
The report said the flaw caused an alarm to go off several times during the flight. That led the pilots to attempt to reset the system, prompting a series of events that led to the plane rolling out of control. Miscommunication between the pilot and second-in-command apparently added to problem, the report said.

"Subsequent flight crew action leading to inability to control the aircraft...<span style="color: Red;">*</span>resulted in the aircraft departing from the normal flight envelope and entering prolonged stall condition that was beyond the capability of the flight crew to recover," the report said.
There were seven crew members and 155 passengers on board — 138 adults, 16 children and one infant. The passengers and crew included three South Koreans, a Malaysian, the French co-pilot, a British national and his 2-year-old Singaporean daughter. The rest were Indonesians.
After the report was released, AirAsia CEO Tony Fernandes tweeted out condolences to those who died. "There are scars that are left on me forever" due to the crash, he said.
"There is much to be learned here for Airasia, the manufacturer and the aviation@ industry," Fernandes said. "We will not leave any stone unturned to make sure the industry learns from this tragic incident."
The crash closed out a bumpy 2014 for Southeast Asia air travel. On March 8 of that year,<span style="color: Red;">*</span>Malaysia Airlines Flight 370<span style="color: Red;">*</span>went missing soon after taking off from<span style="color: Red;">*</span>Kuala Lumpur<span style="color: Red;">*</span>for<span style="color: Red;">*</span>Beijing with 239 people aboard. Four months later, another Malaysia Airlines flight was shot down over eastern<span style="color: Red;">*</span>Ukraine<span style="color: Red;">*</span>while on a flight from Amsterdam to Kuala Lumpur. The 298 people on board were killed.
