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.
INDONESIA'S DIRECTORATE GENERAL OF CIVIL AVIATION
-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.
FEDERAL AVIATION ADMINISTRATION
-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.
BATAM AERO TECHNIC
-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)
