Boeing has urged airlines to suspend the use of 777 jets with the same type of engine that shed debris over Denver at the weekend.
U.S. regulators have announced extra inspections.
And Japan suspended use of the planes there while considering further action.
The moves involve 777s with Pratt & Whitney PW4000 engines.
The right engine on a United Airlines jet failed on Saturday (Feb 20), scattering its protective outer casing over a residential area.
United said the next day it would voluntarily and temporarily remove its 24 active planes of the type.
Boeing said 69 of the the model with PW4000 engines were in service and 59 were stored.
It comes at a time when airlines have grounded planes due to a plunge in demand amid the health crisis.
The manufacturer recommended that airlines suspend operating the 777 until U.S. regulators identified the appropriate inspection protocol.
It's another headache for the plane maker after its 737 MAX crisis.
And comes after criticism of U.S. Federal Aviation Administration oversight regarding the MAX.
There were also issues for Boeing in the Netherlands on Monday.
The Dutch Safety Board said it was investigating what had caused a Boeing 747-400 to lose parts of an engine shortly after taking off from Maastricht airport on Saturday (February 20).
The cargo plane scattered mostly small metal parts over a southern Dutch town
It caused damage to cars and left one person with minor injuries.
