JAKARTA, Indonesia (AP) – An Indonesian pilot shouted “Pull up! Pull up!” seconds before his jetliner plunged into the sea last year, killing all 102 people on board, according to an investigation Tuesday that blamed his errors and a faulty navigation system for the disaster.

The government revoked low-cost carrier Adam Air’s operating license because of its poor safety record. The National Transportation Safety Committee said 154 recurring defects in the plane’s navigation system were reported in the months leading up to New Year’s Day crash, and that the carrier failed to properly address those reports or train pilots to deal with them.

The plane was flying from the main island of Java to an airport in the east of Indonesia when it spiraled from the sky at a height of 10,000 meters. It took around two minutes to hit the sea. Several days before fisherman and navy boats discovered wreckage from the plane floating on the ocean. Both flight data recorders were eventually recovered from the sea bed, but the plane’s mostly intact fuselage remains there.

The pilots reported a problem with the navigation system, but they sounded unconcerned, even joking at 20 minutes before it went down. In the course of trying to fix the problem, the jetliner’s autopilot disengaged, causing the plane to bank to the right.

In February 2006, another of its Boeing 737s went missing for hours following a navigation and communications breakdown and eventually made an emergency landing hundreds of miles from its destination in eastern Indonesia.

Relatives of those who died in the accident said they were angry with Adam Air following the release of the investigation results, with some vowing to pursue legal action against the airline.
