CFM wins approval for jet engine durability boost

CFM International, a jet engine manufacturer, announced that it had received approval from the U.S. as well as?Europe for an upgrade to improve 'durability of engines utilised on Boeing 737 -MAX -jets.

The "durability kit" will be available for LEAP-1B engine models that are powered by Airbus A320neo jets, which use the LEAP-1A model.

CFM executives said in a press briefing before the Farnborough Airshow that it would double "time on wings" or gaps between critical repairs, especially for hot and harsh environments such as?the Middle East or India.

In recent years, long waiting times for repair have been a major concern and hampered a part of the fleets. However, this has gradually eased.

The problem stems from the significant fuel savings achieved in the latest engine generation, but at the cost of high wear and tear. This has led to longer waiting times for repair and forced some airlines to ground their aircraft.

CFM announced that it has?now?reach a "near-zero" number of LEAP powered planes that are grounded due to delays in maintenance.

CFM and Pratt & Whitney compete to power A320neo aircraft. Both have reported steady improvements in maintenance delays, as well as a reduction of'metal contamination' issues.

CFM stated that its new update will be available on new engines and can be added to the maintenance line. (Reporting and editing by Aidan Lewis; Tim Hepher)
