Boeing Plane Crashed in Indonesia After Key Sensor Replaced

The bulletin warns operators that erroneous readings from a flight-monitoring system can cause the new 737 Max models to aggressively dive

Boeing said it had issued an "Operations Manual Bulletin" addressing flight crew procedures in cases where there is "erroneous input from an [Angle of Attack] sensor".

Based on preliminary findings from an investigation of the crash, Boeing Co. has warned airlines operating the new 737 Max that erroneous readings from a flight-monitoring system can cause the planes to do just that - abruptly dive. The manufacturer cautioned that the so-called angle-of-attack sensor can provide false readings in limited circumstances that cause the 737 Max to pitch nose downward.

This warning extends to both Air Canada and WestJet pilots, since both the airlines use 737-Max planes regularly.

"The center will undertake relevant work involving the installation, coating and maintenance of the 737 Max and it is expected that the full capacity of the center will reach 100 planes a year, the statement said". In short they have to accommodate everyone from the best trained pilots in the world to the worst.

Just a week after a Lion Air passenger plane crashed into the Java Sea killing all the 189 people on board, another jet of the budget carrier has been involved in an accident.

Flight JT610 radioed a request to return to Jakarta to land, but never turned back toward the airport, according to Indonesia's National Transportation Safety Committee.

"The draft of what will be conveyed by Boeing this morning has been presented to us", said air accident investigator Nurcahyo Utomo.

Data from the black box of the Lion Air 737 Max that fell into the sea with 189 people onboard has confirmed there was an issue with the plane's airspeed indicator.

It seems patently obvious to say that such situations shouldn't happen in this day and age-and clearly the investigation is still in its earliest stage-but it is troubling to see something so deadly transpire in the most modern aircraft in the Boeing fleet.

The Boeing alert to 737 MAX operators to follow the manual when erroneous data problems are encountered from flight sensors raises more questions than it answers in relation to the Lion Air crash on Monday, October 29.

A Lion Air plane, which was carrying 145 passengers, was forced to abort its take-off after its left wing crashed into a pole.

He said the pilot had landed the plane safely on that occasion.

"Over the last 40 years, Boeing and Chinese partners have built deep relations in all industrial chains, including the research of new technologies, parts manufacturing as well as flight maintenance and modification", the statement said.

"We have extended the operation for three more days", Muhammad Syaugi, the head of the national search and rescue agency (Basarnas), told Reuters.
