In the wake of a disaster, Boeing is on defense as a group of pilots claims the company failed to impart essential safety information about a new jet feature.
"We tried to talk and make jokes, like it's just a normal day". Boeing have admitted that there was no reference to this safety feature in any of the documentation either. "We ensure that we provide all of the information that is needed to safely fly our airplanes", he said in an interview with Fox Business Week. Investigators believe the system may have been triggered on inaccurate data transmitted or processed from sensors on the fuselage, causing the plane to nosedive into the water.
"We value our partnership with Boeing, but were unaware of some of the functionality of the Manoeuvring Characteristics Augmentation System (MCAS) installed on the MAX 8", an American Airlines spokesman said.
Boeing made modifications to the anti-stall system without informing air carriers and their crews, according to the Allied Pilots Association.
"How this happened is definitely something which has to be resolved", said Tajer, who pilots 737s himself. The company has been relying on revenue gains from faster output of the narrow-body jet to help ease financial strain from introducing its newest wide-body aircraft, the 777X.
Boeing released an operational bulletin last week, warning all airlines about how to address any erroneous readings related to the angle of attack (AOA) sensors.

Cues like the sculpted bonnet, slim headlamps and trademark Aston Martin grille are derived from the concept. The very sporty utility vehicle will be called the DBX when it goes on sale in about a year.
The accident is the first to be reported involving the widely sold Boeing 737 MAX, an updated, more fuel-efficient version of the manufacturer's workhorse single-aisle jet. American, the world's largest airline, has outstanding orders for 85 of the planes.
According to the WSJ, Boeing told airlines that such a situation "can result in a steep dive or crash - even if pilots are manually flying the jetliner and don't expect flight-control computers to kick in".
As per the recently issued directive, this could persist for up to 10 seconds, and is so forceful and unexpected that the pilot would have little chance of stopping it happening.
Pilots can stop this automated response by pressing two buttons if the system behaves unexpectedly, the directive said.
Indonesian investigators said on Monday a system created to deal with the accident scenario was not described in the flight manual.
As speculation continues as to whether the flight-control system was indeed to blame for the fatal crash in Indonesia, authorities are still searching for the aircraft's black box, which could contain information on what exactly was going on in the cockpit at the time of the crash.
Recovery of the CVR could give vital insights into the actions the pilots took at the time of the crash, but as the location signal was lost around a week ago, it's unlikely it will ever be found.
