FACTBOX-Indonesia's recommendations in the Lion Air crash report

Oct 25 (Reuters) - Indonesia's National Transportation Safety Committee (KNKT) issued dozens of recommendations to improve air safety as part of a report it released Friday on the Lion Air Boeing 737 MAX crash last year that killed 189 people.

The recommendations are for Lion Air, which operated the aircraft; Boeing, which built it; AirNav Indonesia, which controls Indonesian airspace; Indonesia's Directorate General of Civil Aviation; the Federal Aviation Administration; the International Civil Aviation Organization; and Batam Aero Technic and Xtra Aerospace, which performed maintenance work on the aircraft.

Among the recommendations:


-Improving training methods in a way that addresses flight crews who are assessed as being unable to meet the minimum requirements.

-Improving cockpit communications in emergencies, including procedures about how to hand control of the aircraft between the pilot and first officer.

-Reviewing manuals to ensure that all procedures are standard, eliminating discrepancies that could cause problems to go unreported or unfixed.


-Review the effects of multiple alerts and alarms on crew, and revisit procedures and training materials to ensure pilots do not take harmful and unexpected action in an emergency.

-New systems should be tested and designed so they can be operated by "a larger population of flight-rated pilots."

-The anti-stall MCAS system should be redesigned to be fail-safe and have a backup.

-Any systems that can take over flight control should be "more closely scrutinized in the certification process."

-All aircraft must conform with the certified design.

-A cockpit alert should tell pilots if sensors measuring angle of attack - the angle of the aircraft's wing relative to the direction of flight - disagree, to prevent relying on bad data.

-Training materials and flight crew manuals must include better information regarding MCAS.


-Review the list of suspected emergency situations so that air traffic controllers can correctly identify when an emergency is taking place.


-Improve oversight to make sure procedures such as maintenance are carried out properly and safely.

-Improve oversight of training materials and manuals.

-Develop better procedures for flight crews to hand control off between the pilot and first officer.


-Improve oversight of system certification processes and maintenance work.

International Civil Aviation Organization

-Develop better guidance for information that should be included in flight crew and engineer's manuals.


-Emphasise that engineers must record the results of tests on components installed in aircraft as part of repairs.

-Establish clear procedures for how to handle recurring problems with aircraft systems.

-Review the process for releasing aircraft from remote airports where the necessary parts for a repair might not be on hand.


-Implement a manual that includes training and procedures to ensure repaired components are properly maintained. (Reporting by Gerry Doyle; Editing by Himani Sarkar)
