The day before a brand new Lion Air jet crashed into the sea shortly after taking off from Indonesia's capital city last fall -- likely due to an equipment malfunction -- an off-duty pilot reportedly helped save the aircraft when it began to dive.
The extra pilot was on the flight from Bali to Jakarta and was seated in the cockpit jumpseat when the crew of the Boeing 737 Max 8 struggled for control of the aircraft, Bloomberg reported on Tuesday.
During the flight, the jet displayed unusual variations in altitude and airspeed in its first several minutes, Reuters previously reported. Some of those variations included an 875-foot drop over 27 seconds when the plane would typically be ascending, before stabilizing and flying on to Jakarta.
As the jetliner was in a dive, the extra pilot figured out what was wrong and told the crew how to disable a malfunctioning flight-control system to save the aircraft, two people familiar with Indonesia's investigation told Bloomberg.
The crew was told to cut power to the motor causing the plane's nose to dive down, which is part of a checklist that all pilots are required to memorize, according to Bloomberg.
Hours later with a different crew on board, the same aircraft crashed into the Java Sea after takeoff, killing all 189 aboard.
Officials investigating the Lion Air crash previously said they were looking into the plane’s anti-stall system, which was engaged and repeatedly pushing down the aircraft’s nose prior to it crashing into the sea. The Indonesia safety committee report also said the plane had had multiple failures on previous flights and hadn’t been properly repaired.

NOTE: This article is about the Lion Air crash in Malaysia, not the Ethiopian crash.
Most of these articles have focused on hardware and software, not on the crews. In the Lion Air case, a failed sensor played a big role. This article point out that the same aircraft had the same problem the day before, but a trained pilot on the flight deck understood the problem and took corrective action. Safe Landing. The very next day, with a different crew, same aircraft, same fault, 189 people died. Issues with crew training and maintenance procedures seem to be key as well as the problems with the MCAS and the AOA sensor.
Looks like a major issue is inadequate pilot training.
3rd World Airline = 3rd World Training
Unnamed source at SE AL tells me they (some Left seaters) have experienced this and corrected in time.
Another tells me (USAF C5A Jockey) and Jet BLUE (Left seater) tells me when they see these 3rd world AL reports they blow them off due to lack of Hrs and training,training and more training.
Things always go bad in a simulator....In reality a glitch grabs you by the ass and weeds out the best.
typing while yer posting.Looks like were on the same tarmac
Yes, and most of the earlier articles have fixated on the hardware and software issues, with no mention of crew training and behavior. Most accidents are a function of multiple errors, just one problem is usually resolved ending in a safe flight.
We have had “Run-Away Trim” incidents since they put ‘em on airplanes, I myself have had at least 8 and I’m still alive (old but Alive)
From DC-3s to B747-400s
Boeing seems to have an obvious hardware/software issue, but one that pilots here seem to be able to handle because of training or that is avoided completely by proper maintenance.
Euroweenies will ban Boeing soon....then good ol President Trump will raise holy he//with the scumbags.
I have a sentimental fondness for the Dakota
I’m a private pilot and ex AF mechanic (C5s).
An instructor once told me “If something unexpected happens in the cockpit, think about what you just changed, and change it back.”
From what I’ve read, the safety system causing these issues doesn’t activate while the flaps are extended, or the auto pilot is set. This explains why the issues occurred after initial takeoff climb, when the flaps would be retracted, but the AP not yet activated.
That being the case, the nose drop would have occurred immediately after take off flaps were retracted. Seems even without knowledge of the safety system or how to counter malfunctions, if the pilots had just re-extended flaps to take off setting, the issue would have stopped.
Change back what you just changed.
Wow, honored to have you here. Way to go.
There are old pilots and bold pilots but there are no old bold pilots.
What is "SE AL?"
And inadequate information sharing. The first crew really should have alerted both the second crew and the airline. And the Airline should have alerted all crews that fly that type plane.
...and the system design of the plane.
BAD combination.
Whoops sorry SW
that out of control horizontal jack screw can pucker yer butt
Sounds like an abysmal lack of communication between flight crews.
The worst trim run-aways were in the 727-100s,, don’t know about the later mods.
