That was the message from the carrier's CEO Michael O'Leary on Thursday (January 11).
He made his comments after some 737 MAX jets were grounded after a recent cabin panel blowout on an Alaska Airlines flight.
"We are not concerned. The number of quality control issues needs to be put in the context of over a million flights that the MAX aircrafts have taken over the past two years. But there is no doubt that Boeing needs to improve and that Spirit Wichita who made the hulls, need to improve quality control and production quality."
U.S. regulators grounded 171 MAX 9 planes on Saturday (January 6) after a panel called a door plug blew off an Alaska Airlines flight.
Ryanair is Europe's largest airline by passenger numbers and one of Boeing's largest customers.
It operates different variants of the 737 MAX from the type that has been grounded.
"So it seems to be confined to this plug on the MAX 9. We don't operate MAX 9s. We see no indication from any of our customers about any concern about the 737."
O'Leary further said the MAX 9 issue was concerning.
But he had confirmed with U.S., European and Irish regulators there was no read across to the MAX 8 model Ryanair flies or MAX 10 it has on order.
Though he did say Boeing had more work to do on quality control, O'Leary said he remained 100% committed to Boeing for future orders.
