This is the best summary I could come up with:

A six-week audit by the Federal Aviation Administration of Boeing’s production of the 737 Max jet found dozens of problems throughout the manufacturing process at the plane maker and one of its key suppliers, according to a slide presentation reviewed by The New York Times.

Last week, the agency announced that the audit had found “multiple instances” in which Boeing and the supplier, Spirit AeroSystems, failed to comply with quality-control requirements, though it did not provide specifics about the findings.

Since the Alaska Airlines episode, Boeing has come under intense scrutiny over its quality-control practices, and the findings add to the body of evidence about manufacturing lapses at the company.

At one point during the examination, the air-safety agency observed mechanics at Spirit using a hotel key card to check a door seal, according to a document that describes some of the findings.

Asked about the appropriateness of using a hotel key card or Dawn soap in those situations, a spokesman for Spirit, Joe Buccino, said the company was “reviewing all identified nonconformities for corrective action.”

The audit raised concerns about the Spirit technicians who carried out the work and found that the company “failed to determine the knowledge necessary for the operation of its processes.”
